Epidermal inclusion cyst of the breast . A literature review

An epidermal inclusion cyst (EIC) of the breast is a rare, benign condition that may potentially be malignant. The present study conducted a systematic review of the literature in order to identify pathological hypotheses, clinical characteristics, and diagnostic and treatment options. A search for relevant studies was conducted through the Scopus, Embase and Medline databases during September 2014. The search term employed was ῾epidermal inclusion cyst breast᾽. Studies were selected if they contained adequate information regarding symptoms at presentation, diagnostic tools, pathology, characteristics, type of procedure performed and follow-up routines. A total of 35 papers describing 91 patients affected by EIC of the breast were identified. Following this, a total of 82 patients, including an additional case supplied from the present study, were selected for further analysis. EIC of the breast typically occurs during the fifth decade of life. A palpable mass of the breast was present in 65 (79%) patients. Ultrasonographic imaging was consistently utilized as a diagnostic tool in all the cases analyzed, whereas fine-needle aspiration cytology was used in 70% of the cases and mammography in 65%. No tumor recurrence was reported at a mean follow-up time of 53 months. The present study demonstrated that elliptical excision is the preferred treatment for EIC of the breast, with pathological analysis required to exclude malignancy

Clinical and surgical aspects of high and low ligation of inferior mesenteric artery in laparoscopic resection for advanced colorectal cancer in elderly patients.

Objective of the present study was the evaluation of the efficacy of the low ligation of the inferior mesenteric artery with lymphadenectomy at the root in rectosigmoid resection for advanced cancer by laparoscopic approach. Ninety-two elderly patients with stage III tumors were retrospectively divided into three groups: low ligation of inferior mesenteric artery with and without lymphadenectomy at its root and high ligation. Anastomotic fistula, lymph nodes harvested and oncologic outcome were examined. Significant differences were registered in the number of lymph nodes comparing high and low ligation with lymphadenectomy to simple low ligation. Only 8.3% of patients treated by lymphadenectomy had metastasis at the root of mesenteric artery. Not significant shorter operative time was observed in the high compared to low ligation. Significantly longer time was observed in low ligation when it was associated to lymphadenectomy. Not significant difference was observed in term of anastomotic leakage. Significant increase in cancer related deaths was observed in the low ligation group without lymphadenectomy. Not significant difference in morbidity was observed in the different groups. Low ligation of the inferior mesenteric artery with lymphadenectomy is a safe and effective procedure in the treatment of advanced rectosigmoid cancer with similar results compared to high ligation. It might be especially indicated in elderly patients with advanced tumors to better define lymph nodes involvement and to improve vascular flow to the anastomosis

Isolated Multifocal Sclerosing Thyroiditis: Case Report

Multifocal fibrosclerosis is a very rare fibroproliferative syndrome involving multiple organ systems. In our report we present the case of multifocal sclerosing thyroiditis characterized by multiple fibroelastic foci similar to breast “radial scar”, which can be misdiagnosed as multifocal papillary carcinoma. The diagnosis of multifocal sclerosing thyroiditis, in according with Armed Forces Institute of Pathology (AFIP) textbook on thyroid tumors, was made only after histological and himmunohistochemical examination. We consider the multifocal sclerosing thyroiditis as the first stage of multifocal IgG4-related sclerosing disease for the presence of IgG4 within fibrosclerotic tissue of thyroid. Total body CT-scan and plamatic IgG4 levels must be investigated in order to exclude or confirm the presence of systemic disease

A rare case of malignant epithelioid angiomyolipoma in multiple locations: Multifocal disease or metastases?

Background: Perivascular epithelioid cell tumors (PEComas), make up a family of extremely rare mesenchymal neoplasms, with characteristic morphological, immunohistochemical and molecular findings. Malignant PEComas and gastrointestinal epithelioid angiomyolipoma (E-AML) are especially rare. To the best of our knowledge E-AML have not been found in the breast. The difficulty in determining what constitutes optimal therapy for PEComas, owing to the sparse literature available, led us to report this rare case. Methods: We report a case of a 44-year-old woman, with a family history of multiple endocrine neoplasia syndrome (MEN) (gastrinoma, medullary thyroid cancer and parathyroid hyperplasia), affected by PEComa located in the kidney, stomach, ileum, liver and breast. Results: The renal, gastric, ileal and mammarian tumors were completely resected, with no evidence of local disease. Liver lesions were biopsied. The morphological and immunohistochemical findings confirm the diagnosis of PEComa. Conclusion: On this basis it is difficult to determine if some E-AML are multifocal tumors or metastatic disease

Surgical treatment of pheochromocytoma in MEN 2.

Multiple endocrine neoplasia type 2 (MEN 2) is a rare autosomal dominant cancer syndrome. Forty to fifty percent of patients with MEN 2A develops pheochromocytoma. Surgeons treating these patients with pheochromocytoma have always been faced with question of whether to perform mono-or bilateral adrenalectomy and the timing of surgical intervention. Over the past 20 years, thanks to the development of ever more sophisticated techniques of diagnostic imaging (TC, MRI, Scintigraphy, PET), which make it possible to identify small lesions, and to ever more rapid laboratory tests, there has been a change in the surgical management of this condition. Surgeons moved from bilateral open adrenalectomy (6- 9) to laparoscopic partial adrenalectomy and cortical sparing (10-13). After partial adrenalectomy one third of the patients require replacement therapy because the function of the residual parenchyma was compromised by excessive devascularization during surgery. In patients with bilateral pheochromocytoma it is advisable to perform only partial adrenalectomy of at least one gland, i.e. to completely remove the gland with the larger lesion and remove part of the gland with the smaller lesion to reduce the risk of recurrence. The authors report 4 cases of MEN 2, including 2 first-degree relatives, which illustrate the progress made in surgical treatment for pheochromocytoma
