Metastatic Lobular Carcinoma of the Breast Presenting with Small Bowel Metastases: Case Report and Literature Review

Introduction: Invasive lobular carcinoma (ILC) is the second most common histologic type of breast cancer, representing 5% to 15% of invasive tumors. ILC tends to spread to bones, lungs, central nervous system, reproductive organs, and the gastrointestinal tract (GI tract). The most commonly affected organs in the GI tract are the stomach, small intestine, followed by colon and rectum. Case presentation: A 78-year-old woman who was referred to our institution after having a bowel obstruction that required a diagnostic laparoscopy where they identified an obstructing ulcerative lesion in the distal ileum that was managed with a segmental bowel resection. Pathology report showed an invasive lobular breast carcinoma that occluded 90% of the bowel lumen. A PET/CT scan revealed a left breast tumor with increased metabolism. The patient was staged as a clinical cT4b, cN0, cM1 left breast invasive lobular carcinoma (ER/PgR positive, HER-2 negative). She was managed with endocrine therapy with Letrozole (an eight-week course). A follow-up PET/CT showed a peritoneal hypermetabolic nodule adjacent to the previous ileal anastomosis. The lesion decreased in size and metabolic activity. In a multidisciplinary fashion, the endocrine therapy was extended for another three months. Another follow-up PET/CT scan was performed three months after the identification of the peritoneal implant that showed that the nodule increased in size and in metabolism. The lesion continued to decrease significantly in size and became metabolically inactivity. Due to the good breast response and the possibility that the ileal nodule could be a granuloma, she underwent an exploratory laparoscopy with excision of the peritoneal nodule, and a modified left radical mastectomy with immediate breast reconstruction (complex wound closure). The final pathology report of the nodule was negative for malignancy. She continued on endocrine therapy and underwent whole breast irradiation four weeks after the operation. Currently, she is free of disease with no evidence of local, regional, or distant recurrence, and she is still on endocrine therapy. Discussion: The time interval between primary breast cancer and gastrointestinal involvement may range from synchronous presentation to as long as 30 years. The clinical manifestations in GI lobular breast cancer metastasis may range from non-specific complaints to acute GI symptoms, such as a bowel obstruction. There are multiple controversies in the management of ILC. Systemic treatment should be initiated as soon as possible. Indications for postmastectomy radiotherapy are also controversial, given the propensity for multifocal/multicentric tumors and late recurrences, sometimes in atypical locations. Five years of postoperative adjuvant hormonal therapy is an option for women with poor prognosis. Remissions are observed in 32% to 53% of patients. Conclusion: Metastatic lobular carcinoma of the breast has a wide range of clinical presentations. Patients with a history of breast cancer who present with new GI tumors should have these lesions evaluated for evidence of metastasis through histopathologic and immunohistochemical analysis, this will allow for appropriate management. Currently, breast cancer management involves a multidisciplinary approach including surgery, radiotherapy, and systemic medical therapy, and the treatment must be tailored to the patient’s needs.

A Patient with Gastric Metastasis of Lobular Breast Cancer with CDH1 Mutation: A Case Report

A Patient with Gastric Metastasis of Lobular Breast Cancer with CDH1 Mutation: A Case Report

Gastric Metastasis of Invasive Lobular Breast Carcinoma, a Current Diagnostic and Treatment Challenge - A Review.

Introduction: The predilection of lobular invasive breast cancer metastasis for the stomach is a topic that has succumbed to various assumptions over the time. Background and Aims: Gastric metastasis of lobular breast cancer is unusual and it can be diagnosed after a long period of time from primary tumor diagnosis. The aim of this study was to review current knowledge regarding the current methods of diagnosis and treatment of gastric metastasis of breast cancer. Methods: A systematic literature search was performed in the Pub-Med Medline database using the terms "gastric metastasis of lobular breast cancer" and "gastric metastasis features" to identify articles relevant to gastric metastasis of lobular breast cancer. Results: Several papers have shown that the topic is rarely presented in the form of case presentations or miniseries by summing up sporadic cases. Due to its rarity and metastasis specificity as host type and appearance after latency of lobular breast cancer makes its gastric metastasis considered atypical and occasionally confused with a primary stomach malignancy. The most recent articles present the immunohistochemical diagnostic criteria of this clinical entity and a new therapeutic approach. Conclusion: At patients with gastric metastasis of lobular breast cancer, obtaining pathologic material and biopsies interpretation can be a real challenge for getting a correct pathologic diagnosis, immunohistochemistry gives us definite diagnosis. The introduction of an endoscopic surveillance protocol for patients with lobular breast cancer could be a proposal for the detection of early gastric metastases allowing for appropriate therapy.

Small bowel obstruction due to ductal breast cancer metastasis

The most frequent sites of breast cancer metastasis are the bone, lung and liver. Metastasis to the gastrointestinal tract, central nervous system and adrenal glands are rare, the gastrointestinal tract more frequently with being affected by lobular breast cancer metastasis, and rarely by ductal breast cancer. The case reports a 52-year-old female patient, previously diagnosed with locally advanced ductal breast carcinoma - cT4N+M0, who received neoadjuvant chemotherapy, followed by modified radical mastectomy – ypT2N3aM0 – and adjuvant radiotherapy. During follow-up there were no signs of recurrence, but the patient experienced several episodes of sub-acute intestinal obstruction, which resolved with medical treatment. In 2017, January the patient had another intestinal obstruction, but this time a laparotomy was performed, and two small bowel metastasis were found, which were resected. The pathologic exam revealed metastasis from ductal breast cancer. In the article have we discussed the patterns of breast cancer metastasis, with special consideration for gastrointestinal tract.

Metastases from lobular breast cancer as an unusual source of GI bleeding.

e12557 Background: With the exception of malignant melanoma, metastases to the GI tract are rare, especially as a first presentation of malignancy. We report a series of patients with GI metastases from lobular breast carcinoma as an unusual source of symptomatic GI bleeding. Methods: We conducted an electronic database search to identify solid tumour patients (excluding melanoma) with metastases to the GI tract. We then analysed the database by tumour type. Results: 3 cases of proven metastasis to the GI tract were identified. All had lobular breast cancer metastases. The database contained 240 patients with breast cancer, identifying 63 with infiltrating lobular carcinoma, 2 with micropapillary and 175 with invasive ductal carcinoma The 1st case had had invasive ductal breast carcinoma 6 years previously and presented with fatigue and shortness of breath from anaemia. Colonoscopy revealed a polyp which was removed. Histopathology showed metastatic lobular breast carcinoma. Further investigation then confirmed an occult breast mass with identical pathology. The 2nd case presented with 18 months of abdominal pain, previous colonoscopy was normal. After onset of anaemia and 25kg weight loss, upper GI endoscopy showed a markedly thickened stomach with evidence of recent bleeding and biopsies confirmed metastatic lobular breast carcinoma. The 3rd case presented with abdominal pain, subsequent blood tests showing a raised CA125 with omental and ovarian masses. Surgical debulking showed metastatic lobular breast carcinoma, though no primary breast lesion was detectable with mammography, ultrasound and MRI. 3 years later, investigation of anaemia with colonoscopy showed a caecal polyp with histology confirming lobular breast carcinoma. Conclusions: Despite all common tumour types being represented in the database it is notable that all 3 cases with mucosal GI metastases had lobular breast cancer. Previous evidence suggests a long latent period from initial diagnosis of breast cancer to development of GI metastases however our report suggests it can occur earlier in the illness. Clinicians should consider this as a rare cause of GI bleeding and further research to understand the mechanism of mucosal metastasis in lobular breast cancer is needed.

Siegelringzellhaltiges Infiltrat in der Kolon- und Magenschleimhaut

A 49-year-old female patient presented with anemia of unclear origin (hemoglobin level 6µg/dl). During coloscopy a circular wall edema in the right flexure of the colon was observed and gastroduodenoscopy gave rise to the suspicion of fundic gland polyps (Elster's cysts) of the mucosa. In the lamina propria of the gastric mucosa, infiltration of a poorly differentiated carcinoma with signet ring cell morphology could be histologically identified resulting in the suspected diagnosis of a primary gastric signet ring carcinoma. Using immunohistochemistry it could be shown that the tumor cells expressed cytokeratin 7 (CK7), estrogen receptors and Gata 3 but not CK20 or Cdx2. The diagnosis of metastases of lobular breast cancer in the gastric and colon mucosa could be made.

Small bowel obstruction from breast cancer metastasis: A case report and review of the literature

Small bowel obstruction from luminal gastrointestinal metastasis is a rare, but recognized, presentation of metastatic breast cancer. Herein, we report a case of a small bowel obstruction from lobular breast cancer metastasis to the terminal ileum, occurring over a decade after diagnosis and treatment of the initial primary cancer. Our review highlights the presentation and management of this unusual disease manifestation, including diagnosis of the gastrointestinal process, identification of the primary cancer, surgical treatment of the abdominal pathology, systemic therapy for metastatic disease, and survival data for patients with this disease process.

Gastric obstruction secondary to metastatic breast cancer: a case report and literature review

IntroductionGastrointestinal tract soft tissues metastasis is a well-known occurrence with invasive lobular breast cancer subtypes. Gastric involvement is more common, with reports of both diffuse and localized involvements. Usually, a gastric localized involvement presents as wall thickening with an appearance similar to that of a gastrointestinal stromal tumour; rarely does a localized metastatic deposit grow aggressively to present as a large tumour causing obstructive symptoms. Our case highlights one such unusual presentation in a patient presenting with non-specific gastrointestinal symptoms. To the best of our knowledge, there have been no previous reports on a similar presentation occurring from a localized metastasis.Case presentationA 65-year-old Caucasian woman awaiting an outpatient oral gastroduodenoscopy for symptoms of intermittent vomiting, epigastric pains and weight loss of six weeks’ duration presented acutely with symptoms of haematemesis and abdominal distension. An initial contrast-enhanced computed tomography scan showed a grossly dilated stomach with a locally advanced stenosing tumour mass at the pylorus. Our patient had a history of left mastectomy and axillary clearance followed by adjuvant endocrine therapy for an oestrogen receptor- and progesterone receptor-positive, grade 2, invasive lobular breast cancer. The oral gastroduodenoscopy confirmed the computed tomography findings; biopsies of the pyloric mass on immunohistochemistry stains were strongly positive for pancytokeratin and gross cystic disease fluid proteins, consistent with an invasive lobular breast cancer metastasis. She received a palliative gastrojejunal bypass and her adjuvant endocrine treatment was switched over to exemestane.ConclusionOur case highlights the aggressive behaviour of a localized gastric metastasis that is unusual and unexpected. Gastrointestinal symptomatology can be non-specific and, at times, non-diagnostic on conventional mucosal biopsies. A high index of clinical suspicion in patients with a previous history of invasive lobular breast cancer can aid in an early diagnosis and treatment. A combined treatment approach with chemoendocrine therapies achieves remission and improves patient survival.

Bilateral synchronous breast carcinomas followed by a metastasis to the gallbladder: a case report

BackgroundBreast cancer is usually associated with metastases to lungs, bones and liver. Breast carcinoma metastasizing to the gallbladder is very rare.Case presentationA 59-year-old woman presented with bilateral synchronous breast lesions. A palpable, retroareolar solid lesion of diameter equal to 5 cm was present in the right breast, and a newly developed, non-palpable lesion with microcalcifications (diameter equal to 0.7 cm) was present in the upper outer quadrant of the left breast. Modified radical mastectomy was performed on the right breast and lumpectomy after hook-wire localization was performed on the left breast, combined with lymph node dissection in both sides. The pathological examination revealed invasive lobular carcinoma grade II in the right breast and invasive ductal carcinoma grade I in the left breast. Chemotherapy, radiation therapy, trastuzumab and letrozole were appropriately administered. At her 18-month follow-up, the patient was free of symptoms; the imaging tests (chest CT, abdominal U/S, bone scan), biochemical tests, blood cell count and tumor markers were also normal. At the 20th month after surgery however, the patient developed symptoms of cholecystitis and underwent cholecystectomy. The histopathological examination revealed metastasis of the lobular carcinoma to the gallbladder.ConclusionThis extremely rare case confirms on a single patient the results of large series having demonstrated the preferential metastasis of lobular breast cancer to the gallbladder. Symptoms of cholecystitis should not be neglected in such patients, as they might indicate metastasis to the gallbladder.
