La mastopathie diabétique : une lésion mammaire bénigne sujette à récidive

Diabetic mastopathy is an uncommon benign entity occurring in young women with type 1 diabetes. Its clinical and radiological signs are not specific and often mimic a breast carcinoma. However, the benign nature of this lesion is easily recognized on histological examination, visualizing dense keloid-like fibrosis, lymphocytic lobulitis and ductitis with lymphocytic perivascular inflammation, with or without epithelioid-like fibroblasts. Surgery can generally be avoided. The evolution of this entity is characterized by the risk of local growth, bilateralisation or recurrence after surgical treatment. We present a case in which the core biopsy allowed the diagnosis of a diabetic mastopathy and we discuss its clinical, diagnostic, pathological and therapeutic particularities.

The Diagnosis and Management of Diabetic Mastopathy

Sclerosing lymphocytic lobulitis is strongly associated with type one diabetes, when it is then known as diabetic mastopathy. This very rare benign condition tends to present in premenopausal women, often with diabetic complications particularly retinopathy. Patients present with clinically suspicious fibrous breast lumps; these are commonly multiple, bilateral, and recurrent. Mammograms show asymmetric densities and no focal mass and ultrasound investigation tends to show ill-defined hypoechoic attenuation with strong posterior acoustic shadowing. Magnetic resonance imaging can be used to further differentiate the lesion from malignancy. However, a core biopsy or excisional biopsy is essential so that a pathologic diagnosis can be made. The constellation of pathologic findings is: lymphocytic lobulitis and ductitis with glandular atrophy, lymphocytic/mononuclear perivascular inflammation which is predominantly B-cell and dense often keloid-like fibrosis, with or without epithelioid-like fibroblasts. A review of the current literature on diabetic mastopathy was carried out as it was noted that there has been no recent review of the literature. Detailed Pubmed and other medical data base searches were carried out and all publications were considered, irrespective of language and date, wherever possible.

Bilateral Extensive Ductitis Obliterans Manifested by Bloody Nipple Discharge in a Patient with Long-Term Diabetes Mellitus

Ductitis obliterans or mastitis obliterans is a rare late manifestation of mammary ductal ectasia. We describe a long-term diabetic patient who presented with bilateral bloody nipple discharge and poorly defined nodularities around the nipple of both breasts. The ductography showed multiple segments of irregular ductal narrowing and intraluminal filling defects in both breasts. The bilateral resection of the sub-areolar portion of the breast showed exuberant fibrous obliteration of the large- and medium-sized ducts by granulation tissue associated with few histiocytes. Ductal dilatation and intraductal accumulation of histiocytes was also present. This represents a late and florid form of mammary ductal ectasia. Differential diagnostic considerations including fibrocystic changes, diabetic sclerosing lymphocytic lobulitis, idiopathic granulomatous lobular mastitis, and periductal mastitis (Zuska disease) are discussed. Accurate diagnosis can help avoid or limit radical surgeries in this group of patients.

An uncommon case of diabetic mastopathy in type II non-insulin dependent diabetes mellitus

Diabetic mastopathy is an uncommon tumor-like proliferation of fibrous tissue of the breast that usually occurs in a patient who has suffered from type I diabetes mellitus of long duration. Here we report a rare case of diabetic mastopathy that occurred in type II non-insulin dependent diabetes mellitus. This patient was a 63-year-old postmenopausal woman. Mammography, ultrasonography and MR imaging could not distinguish it from breast cancer. Although the core needle biopsy specimen showed fibrosis without evidence of malignancy, excisional biopsy was performed. Histological findings demonstrated typical diabetic mastopathy with keloid-like fibrosis, perivascular lymphocytic infiltration, and lymphocytic lobulitis without evidence of malignancy. These lymphocytes were composed predominantly of B-cells. Five months after surgical biopsy, a nodular formation approximately 4 cm in diameter recurred adjacent to the resected end of the biopsy.

Screen detected sclerosing lymphocytic lobulitis and amyloid of the breast in the same patient—a possible causal link

Sclerosing lymphocytic lobulitis (SLL) and amyloidosis of the breast are both rare. We report the case of a 59 year old woman who presented with suspicious microcalcifications on routine screening mammography. Wire-guided excision biopsy showed features typical of SLL but also localised amyloid deposits within the specimen. Amyloidosis and SLL may have similar immunological causes. This patient represents the first documented association of these two disorders.

Granulomatous mastitis: a clinicopathological review of 26 cases

Twenty-six cases of granulomatous mastitis were examined to determine the common histological and clinical features and the possible association with micro-organisms. A retrospective review of the clinical and histological features of these cases was undertaken, including granuloma, inflammatory cell infiltrate, multinucleated giant cells, necrosis and lymphocytic lobulitis, as well as special stains for micro-organisms including Mycobacterium, other bacteria and fungus. PCR for Mycobacterium tuberculosis DNA was also performed in 19 cases. Granulomas were present in all cases (100%) while multinucleated giant cells were seen in 17 cases (65%), background inflammatory cell infiltrate in 23 cases (88%), predominantly lymphocytes in 18 cases (69%), significant lymphocytic lobulitis in 13 of 19 cases (68%) and necrosis in three cases (11%). Special stains and cultures for micro-organisms were all negative. Clinically, four cases (15%) were associated with duct ectasia, eight (31%) with abscess, and there was no such association in 14 cases (54%). Of the 19 cases with PCR for tuberculosis, one case showed Mycobacterium DNA in the sample, raising the possibility of occult tuberculosis infection. Granulomatous mastitis is a heterogeneous group of diseases with a diverse clinical picture and association. Most idiopathic cases are not associated with specific micro-organisms.

Diabetic sclerosing lymphocytic lobulitis of the breast

Diabetic sclerosing lymphocytic lobulitis of the breast (SLLB) as a complication of long standing diabetes is a benign disease without known tendency to malignant evolution. Clinically, it is characterized by solitary or multiple rock-hard discrete lesion(s) in one or both breasts, usually in a subareolar site, but may appear equally in any part of the breast. Mammographically and morphologically, this lesion simulates cancer. The lesion may recur after excision in the same site or in another location of the ipsilateral or the contralateral breast. Awareness of this entity, establishment of the diagnosis by open biopsy or by core needle biopsy may spare the need for repeated wide excisions and the resulting distortion of the breast architecture. The aim of this review is to arouse the awareness of the physicians and surgeons to this possibility when they find a similar lesion in the breast of a diabetic patient.

Sclerosing Lymphocytic Lobulitis of the Breast in a Patient with Graves' Disease

A 43-year-old woman presented to the endocrinologist with symptoms and signs of typical thyrotoxicosis caused by Graves' disease. Review of systems revealed that she had recently discovered a lump in her left breast. Evaluation of the left breast lesion led to a core biopsy that showed sclerosing lymphocytic lobulitis. This breast disease, well recognized in the pathology literature, occurs in various autoimmine disorders, particularly type 1 diabetes mellitus, and has occasionally been reported in Hashimoto's thyroiditis. The patient described here represents the first published association of sclerosing lymphocytic lobulitis of the breast with Graves' disease.

Mastopathy and diabetes.

Sclerosing lymphocytic lobulitis or "diabetic mastopathy" is strongly associated with type 1 diabetes but may occur occasionally in its absence. It is characterized by keloid-type fibrosis, lymphocytic lobulitis, and perivasculitis and epithelioid cells. Infiltrating cells are predominantly B lymphocytes. It may be associated with retinopathy and neuropathy, but more research is needed to verify this association. The etiopathogenesis is unknown and the disorder does not seem to predispose to breast carcinoma or lymphoma.

"Diabetic mastopathy," or sclerosing lymphocytic lobulitis, is strongly associated with type 1 diabetes.

To demonstrate the strong association of diabetic mastopathy or sclerosing lymphocytic lobulitis with type 1 diabetes mellitus by studying appropriate control groups and to describe risk factors and natural history of the disorder. This was a retrospective cross-sectional study of four groups of patients conducted at a setting tertiary care medical center. We examined benign breast biopsies (investigator masked to identity) from age-matched patients with types 1 and 2 diabetes, autoimmune thyroid disease, or none of the above disorders for sclerosing lymphocytic lobulitis. Several risk factors proposed for the disorder (age at diagnosis of benign breast disease, duration of diabetes, age at onset of diabetes, prevalence of retinopathy, neuropathy, nephropathy and cheiroarthropathy, glycemic control, parity, oral contraceptive use, menopausal status, or number of breast biopsies) were evaluated, and patients were contacted to describe the natural history of the disorder. Sclerosing lymphocytic lobulitis was identified in 69.7% of the subjects with type 1 diabetes and 1.8% of those with autoimmune thyroid disease diagnosed with benign breast disease at surgery. It did not occur in patients with type 2 diabetes with or without insulin treatment or in control subjects. Only retinopathy and peripheral neuropathy were associated with sclerosing lymphocytic lobulitis. Breast carcinoma or lymphoma did not occur subsequently in any type 1 diabetes patient with or without sclerosing lymphocytic lobulitis. Sclerosing lymphocytic lobulitis is strongly associated with type 1 diabetes. Retinopathy and neuropathy are associated with the disorder. The risk of malignancy is not increased.

Lymphoepithelioma-like carcinoma of the breast with associated sclerosing lymphocytic lobulitis

The purpose of this article is to highlight an unusual form of breast carcinoma and discuss its differential diagnosis. A 50-year-old woman underwent wide local excision of a breast lump. Microscopic examination revealed features of a lymphoepithelioma-like carcinoma. Individual tumor cells were present within an abundant lymphoid stroma. Immunohistochemistry revealed the epithelial nature of the cells and excluded a diagnosis of lymphoma. In addition, surrounding nontumorous breast tissue displayed the histologic features of sclerosing lymphocytic lobulitis or lymphocytic mastopathy. This is the second report of a lymphoepithelioma-like carcinoma of the breast, but to the best of our knowledge, it is the first description of coexistent sclerosing lymphocytic lobulitis.

Diabetic mastopathy. A clinicopathologic review.

Diabetic mastopathy, an uncommon form of lymphocytic mastitis and stromal fibrosis, typically occurs in longstanding type 1 diabetes. Nineteen cases meeting predetermined histopathologic criteria for diabetic mastopathy were correlated as to clinical history and disease recurrence. Physical examination revealed palpable discrete masses or diffuse nodularity, both predominantly in the subareolar region. One nonpalpable lesion was detected incidentally during reduction mammoplasty. All cases contained lymphocytic ductitis and lobulitis with varying degrees of keloidal fibrosis, vasculitis, epithelioid fibroblasts, and lymphoid nodule formation. Single mammary lesions were found in 11 patients with type 1 diabetes, 1 with type 2 diabetes, and 3 without diabetes. Four cases were bilateral (3 patients with type 1 and 1 patient with type 2 diabetes). Six of 19 cases recurred (3 ipsilateral, 2 contralateral, and 1 bilateral). We confirm the histopathologic constellation for diabetic mastopathy. However, we question the specificity of these features because of identical findings in patients with type 2 diabetes and nondiabetic patients. We found diabetic mastopathy in men and women, as a solitary mass or bilateral disease, and recurrence in either breast, sometimes multiple. Recognition of potential recurrence is important because it might spare patients with documented diabetic mastopathy from repeated breast biopsies.

Sclerosing lymphocytic lobulitis of the breast

<h2>Abstract</h2> Sclerosing lymphocytic lobulitis of the breast is an uncommon condition which clinicians need to be aware of. The disorder has characteristic pathological features; however, findings on triple assessment may be equivocal. In this paper we report ten cases of sclerosing lymphocytic lobulitis and outline the clinical, cytological and radiological features of this condition. Patients, often diabetic, typically present with discrete firm breast lumps. Fine needle aspiration cytology is either acellular or benign and mammography is normal or indeterminate whereas ultrasonography is usually suspicious of malignancy. If the condition is recognized prior to surgery, excision biopsy in patients who are often diabetic may be avoided.

A Case of Sclerosing Lymphocytic Lobulitis of the Breast Associated with Diabetes Mellitus.

BACKGROUND: The benign breast disease sclerosing lymphocytic lobulitis is thought to result from autoimmune diseases causing insulin-dependent diabetes mellitus (IDDM) due to insulinitis. In cases of sclerosing lymphocytic lobulitis accompanied by IDDM, the clinical term gdiabetic fibrous breast disease hhas been proposed. METHODS: A case of sclerosing lymphocytic lobulitis of the breast is described RESULTS: The patient was a 43-year-old woman diagnosed with non insulin-dependent diabetes mellitus (NIDDM) 8 years previously. Insulin therapy was thought to be necessary because treatment with glibenclamide was not effective. She visited our facility complaining of a lump in her right breast that was 5 cm in diameter, painless, rock-hard, discrete, and irregularly outlined. Biopsy was performed because breast cancer was strongly suggested by its hardness and its irregular internal echo on ultrasonography. Histopathological findings demonstrated marked stromal sclerosis and lymphocyte infiltration in the perivascular and perilobular areas. Sclerosing lymphocytic lobulitis was diagnosed. CONCLUSION: Referring physicians should avoid performing unnecessary repeated biopsies by recognizing this disease entity, which often occurs bilaterally.

Inflammatory infiltrate in invasive lobular and ductal carcinoma of the breast.

The significance of inflammation in carcinoma of the breast is controversial. Little attention has been paid to different patterns of inflammation or inflammation associated with different histological types of carcinoma. We have looked at the pattern of inflammation in 123 invasive mammary carcinomas (including 46 lobular), and characterised the inflammatory cells with immunohistochemistry in 21. We found different patterns of inflammation in ductal and lobular carcinoma. Diffuse inflammation was seen more in ductal carcinoma, particularly of high grade, and was predominantly composed of macrophages and T cells. It was associated with necrosis, but the correlation was weak, suggesting that other factors are important. Perilobular inflammation was seen most frequently in lobular and high-grade ductal carcinomas, particularly at the tumour edge. Perivascular inflammation was also largely at the tumour edge, but was not more common in any tumour type. In contrast to the diffuse inflammation, the perivascular and perilobular inflammation was composed of T and B cells. Normal lobules at the tumour edge showed consistent expression of HLA-DR, whereas lobules away from the tumour were negative. A combination of perilobular and perivascular inflammation composed of B and T cells with epithelial expression of HLA-DR mimicking lymphocytic lobulitis was seen more frequently in lobular than ductal carcinoma.

Sclerosing lymphocytic lobulitis of the breast

Eight patients are described who had palpable breast lumps with clinical and imaging features suspicious of malignancy which proved to be sclerosing lymphocytic lobulitis on histological examination. In this series the typical mammographic appearance of this condition was increased parenchymal density and/or localized stromal distortion while on ultrasound, the typical appearance was an ill-defined mass with distal acoustic shadowing. This rare benign condition has been described in association with longstanding insulin-dependent diabetes or autoimmune disease, but four of our eight patients had no such medical history.
