De novo primary malignant lymphoma of the dura following recurrent episodes of subdural abscess presenting as chronic subdural hematoma: illustrative case.

Chronic inflammation of the thorax, as in tuberculosis-related pyothorax, can cause secondary malignant lymphomas. However, primary malignant lymphoma of the central nervous system, specifically of the dura mater, developing after intracranial infection or inflammation has rarely been reported. Herein, the authors describe a case of primary dural lymphoma that developed secondary to subdural empyema, with an initial presentation mimicking a chronic subdural hematoma. A 51-year-old man had undergone single burr hole drainage for subdural empyema 2 years prior. The patient subsequently underwent multiple craniotomy and drainage procedures, with successful remission of the subdural empyema. He was subsequently referred to the authors' hospital approximately a year after his initial treatment because of a recollection of subdural fluid, which was suspected to be recurrent empyema. After another single burr hole drainage, which revealed only a subdural hematoma, a histopathological diagnosis of B-cell lymphoma of the dural/subdural membrane was made. Subsequent radiation therapy was completed, with good local control and no recurrence of the subdural hematoma confirmed at 2 months posttreatment. Intracranial lymphoma triggered by chronic inflammation is rare but should be considered a differential diagnosis in subdural hematomas for which the background pathology is unclear. https://thejns.org/doi/10.3171/CASE24153.

Auriculate Ulcers in Gastrointestinal Tract

An 89-year-old man was referred to our hospital for painless hematochezia. Blood tests revealed moderate anemia, abnormal liver function tests, and an elevated serum lactate dehydrogenase. A thoracoabdominal computed tomography showed multiple solitary liver masses and diffuse lymphadenopathy, and peritoneal dissemination was suspected. An esophagogastroduodenoscopy and colonoscopy revealed multiple elevated lesions with an auriculate ulcer mound in the stomach (Figure A, white-light image; Figure B, contrast method by indigo-carmine spraying), duodenum, and colon (Figure C, magnifying narrow band imaging), consistent with secondary malignant lymphoma.

Breast involvement in immunolymphoproliferative disorders: Report of a case of multiple myeloma of the breast

Summary: Breast involvement by immunolymphoproliferative disordersis rare. Primary and secondary malignant lymphomas of the breast are much more common than multiple myeloma, of which only a few cases have been described. We report a case of a patient with an established diagnosis of multiple myeloma in whom breast involvement appeared after the completion of the treatment. We underline diagnostic difficulties caused by the lack of clinical and radiological features which allow us to differentiate between breast carcinoma and breast involvement by lymphoproliferative disease. Only fine needle aspiration and/or excisional biopsy can differentiate between immunolymphoproliferative disorders and epithelial or mesenchymal tumors of the breast. I. Introduction Multiple myeloma(MM) is the most frequent lympho-immunoproliferative disorders, but their localization in the breast is quite rare. MM is a disseminated malignant B-cell lineage neoplasm, characterized by clonal proliferation of plasma cells in the bone marrow, associated with the overproduction of structurally homogeneous immunoglobulins (M-component). They represent the most frequent form of plasma cell dyscrasias and about 1% of all types of tumors [1]. The incidence increases progressively with age and the mean age at diagnosis is about 65 years, while the onset in children [2] and young adults before 40 years is very rare [3]. Impaired hemopoiesis, renal failure, osteolytic bone lesions, recurrent infections, hypercalcemia are the most common features of the disease. Clinically apparent extraosseous manifestation are present in less than 5% of patients with multiple myeloma and are usually associated with more aggressive behaviour, resistance to treatment and shorter survival.

MR features of primary and secondary malignant lymphoma of the pancreas: a pictorial review

ObjectiveTo describe the imaging findings of primary and secondary pancreatic malignant lymphoma on magnetic resonance imaging (MRI), to help differentiate lymphoma of the pancreas from primary adenocarcinoma and autoimmune pancreatitis among others, and to discuss a few atypical presentations of pancreatitis mimicking lymphoma.ConclusionKnowledge of these imaging manifestations of lymphoma may be helpful to arrive at an accurate diagnosis and avoid unnecessary morbidity and mortality from inadvertent surgery.Main Messages• Pancreatic malignant lymphoma is shown as a nodular low-density area with mild enhancement on CT.• It sometimes shows variable manifestations mimicking other tumours and inflammatory conditions.• MRI provides useful information for differentiating malignant lymphoma from other mimickers.

Bladder mucosa lymphoma: clinical and pathological characteristics and treatment

Objective To analyze the clinicopathologic characteristics and treatment of primary and secondary bladder mucosa lymphoma. Methods From June 1996 to September 2011,8 cases of bladder mucosa lymphoma patients including primary bladder mucosa lymphoma patients (2 males and 3 females)and secondary bladder mucosa lymphoma patients ( 1 male and 2 females) were treated in our institute.The patient's mean age was 68 years (ranged from 57 to 78 years),and the other 3 secondary bladder mucosa lymphoma patient's mean age was 61 years (ranged from 41 to 81 years).7 of 8 patients accepted transurethral resection of bladder tumor combined with CHOP chemotherapy and radiotherapy,and 1 patient abandoned treatment.CHOP chemotherapy and radiotherapy were performed at 2 weeks post-operatively.Secondary bladder mucosa lymphoma patients accepted 3-dimensional conformal 6000 cGy radiotherapy.Urinary CT examination showed that there were round or oval irregular tumors in the wall of urinary bladder,whose diameters were 1 to 4 cm.Tumor edges were glossy and tumor density were uniform.In addition,the bladder wall with tumor was uneven.In contrasted CT,the tumors appeared obviously enhanced.7 cases had cauliflower-like tumors found by cystoscope,and there were necrosis-calcification area in the center of tumors.1case appeared multiple tumors,which consisted of one big tumor and three smaller ones. Results There were 5 cases of primary bladder mucosa lymphoma, including 3 bladder mucosa associated lymphoma (MAL) cases and 2 diffuse large B cell lymphoma cases.There were 3 secondary bladder mucosa lymphoma cases including 2 diffuse large B cell lymphoma cases and 1 generalized follicular cystic central lymphoma case,which belongs to the tuberous sclerosis Hodgkin lymphoma.Immunohistochemical analysis showed that CD20,CD21,CD43 staining were positive in low grade MAL (3 cases).However,CD3,CD20,CD31 staining were positivein high grade MAL (5 cases). All patients were followed up 3 to 44 months.3 cases of secondary malignant lymphoma patients died after diagnosed after 3 to 13 months.5 cases of primary malignant lymphoma patients were all survived. 1 case recurred 14 months after surgery and accepted TURBT and CHOP chemotherapy again.Pathologic diagnosis showed the transformation from peripheral zone of bladder mucosa associated lymphoma to diffuse large B cell lymphoma.The patient was free of recurrence. Conclusions MAL and diffuse large B cell lymphoma are the most common type of bladder mucosa lymphoma.Primary and secondary diffuse large B cell lymphoma have similarities in histological analysis,but the former prognosis is better than the latter's. Transurethral resection of bladder tumor combined with chemotherapy and radiotherapy can prevent the relapse of MAL in short term and long term with good tolerance,and can be used as ideal treatment of MALT.

Primary non-Hodgkin's lymphoma of rectum presenting with rectal prolapse

Involvement of the rectum by primary or secondary malignant lymphoma is uncommon in adults. Primary lymphoma of the rectum in children is an extremely rare occurrence. We describe a 12-year-old boy with a localized rectal tumor that presented with rectal prolapse and bleeding, mimicking a juvenile polyp. He underwent transrectal local wide excision of the tumor, and the pathologic condition proved to be non-Hodgkin's lymphoma of diffuse large B-cell type. This case illustrates the importance of considering the possibility of a rectal malignancy manifesting as a rectal prolapse even in children and the surgical strategy used.

Breast involvement in immunolymphoproliferative disorders: Report of two cases of multiple myeloma of the breast

Breast involvement by immunolymphoproliferative disorders is rare. Primary and secondary malignant lymphomas of the breast are much more common than multiple myeloma, of which only 16 cases have been described. We report two cases of patients with an established diagnosis of multiple myeloma in whom breast involvement appeared during the course of the disease. We underline diagnostic difficulties caused by the lack of clinical and radiological features which allow us to differentiate between breast carcinoma and breast involvement by lymphoproliferative disease. Only fine needle aspiration and/or excisional biopsy can differentiate between immunolymphoproliferative disorders and epithelial or mesenchymal tumors of the breast.

Secondary malignant lymphoma which simulated primary thyroid cancer

A patient with secondary thyroid lymphoma who complained of a neck mass was presented. Multiple nodules were detected in both lobes of the thyroid gland, which appeared as homogeneous hypoechoic masses on ultrasonogarphy (US), low-density masses on computed tomography (CT), and areas of increased uptake on gallium-67 scintigraphy. The residual thyroid gland was normal. Surgery established a diagnosis of secondary thyroid lymphoma with no coexistent Hashimoto's thyroiditis but with cervical node involvement by lymphoma. Radiologic evidence of normal residual thyroid gland in a patient with thyroid lymphoma may be a sign of secondary thyroid lymphoma.

Lymphomatoid papulosis followed by large-cell lymphoma: immunophenotypical and genotypical analysis

The immunophenotype and genotype of atypical cells in skin and lymph node infiltrates were investigated in a patient with lymphomatoid papulosis (LyP) complicated by anaplastic large-cell lymphoma of the lymph nodes. The large atypical cells in both skin and lymph nodes displayed an almost identical immunophenotype, i.e. CD30+ and CD25+. Southern blot analysis for T-cell receptor beta-chain gene rearrangement revealed an identical gene configuration in DNA extracted from skin and lymph node. Our results strongly support the hypothesis that clonal populations of T cells arising in cutaneous LyP lesions may undergo malignant transformation, spread into regional lymph nodes, and give rise to secondary malignant lymphomas, such as anaplastic large-cell lymphoma.

Computed Tomography and Histologic Appearance of Pancreatic Metastases from Distant Sources

The computed tomographic and histologic appearances in 34 cases of autopsy-confirmed metastatic tumors of the pancreas including secondary malignant lymphoma are discussed. In 18 (53.8%) the pancreas appeared abnormal on computed tomography, the lesions being classified into three types: In 8 cases there was diffuse enlargement of the pancreas; in 9 cases a localized mass; and one patient had multiple low attenuated nodules within the organ. Histologic investigation revealed that metastatic carcinoma involved the pancreatic lobules. The degree of infiltration in the interlobular connective tissue was related to the invasiveness of the tumors. In the majority of cases with diffuse infiltration the pancreatic lobules were destroyed and varying degrees of proliferation of malignant cells into the interlobular septa were documented. In patients with localized infiltration there was extensive invasion of the carcinoma within the pancreatic lobule. Dilatation of the pancreatic duct and/or organ-related symptoms were occasionally seen in these cases.

Lymphomatoid granulomatosis and malignant lymphoma of the central nervous system in the acquired immunodeficiency syndrome

While primary and secondary malignant lymphomas have been well-documented in the CNS of patients with the acquired immunodeficiency syndrome (AIDS), only one case of lymphomatoid granulomatosis (LG) involving the CNS has been reported. We present three AIDS patients with multiple grossly evident foci of necrosis in the cerebral hemispheres which, on histologic evaluation, were seen to contain angiocentric mixed chronic inflammatory infiltrates with atypical mononuclear cells, luminal thrombosis, and infarction, which is typical of LG. LG was also identified in sections of the lung in one case. Lymphoma was found in other regions of the brain in two cases, suggesting the evolution of LG into cerebral lymphoma. In addition, widespread perivascular multinucleate syncytial giant cells, associated with human immunodeficiency virus (HIV) infection of the CNS, were identified in all patients. The features of LG, its relationship to lymphoma, and the possible etiologic role of an immunodeficiency state or the HIV virus in the pathogenesis of LG are discussed.

Kernspintomographie in der Mammadiagnostik

The authors report about their preliminary experience with MRI in the diagnosis of breast disease. 50 breast masses in 41 consecutive patients have been evaluated by MRI and mammography, some of which have been evaluated by ultrasound, as well. All masses have consequently been biopsied. They include 32 carcinomas, 1 secondary malignant lymphoma, 4 fibroadenomas, 2 papillomas, 3 cysts, 1 hamartoma and 5 dysplastic nodules. Advantages and disadvantages of MRI of the breast are discussed. Possible future indications are suggested for selected cases.

Lymphoreticular tumors of the orbit

Lymphoreticular tumors in the orbit are uncommon. Only 42 patients were identified from over 2000 patients with tumors of lymphoid tissue seen between 1958 and 1979. The patients were divided into 3 groups: primary malignant, secondary malignant, and benign lymphoma. In the primary malignant lymphoma groups, there were 24 patients with a median age of 64 (40 to 87) years and a 2.4:1 female to male ratio: 2 cases were bilateral. In 19 (79%) patients with the lymphoma limited to one orbit the tumor was controlled in every case with doses from 25 to 45 Gy. There were no serious complications. Subsequently lymphoma developed at other sites in 7 (37%) patients. The 5 and 10 year cause specific actuarial survival rates were 70 and 62%. In the 8 patients with secondary malignant lymphoma, the orbital disease was controlled by irradiation, although all patients required further treatment and died of their disease. Radiotherapy controlled all 7 patients with benign lymphoma without any complications.
