Granular cell tumor of the trigeminal nerve.

Male breast cancer is a rare disease and it differs from breast cancer in women by some characteristics. The incidence of the disease has increased in the last 25 years. The records of male patients who underwent surgery for breast cancer between 2007 and 2017 were retrospectively reviewed in a tertiary care hospital in Istanbul, Turkey. The patients' ages, background, family history, clinical features, histopathological features of the tumour, its stage, the treatment and the survival were investigated. SPSS 15.0 for Windows programme was used for statistical analysis.Survival analysis was performed with Kaplan-Meier method.Determinants were analysed by univariate Cox regression analysis. A total of 15 patients were evaluated in our study. Fourteen patients had invasive ductal carcinoma and one patient had intraductal papillary carcinoma. The median followup period of the patients was 36 months The axillary lymph node metastasis positivity rate (number of metastatic lymph nodes/number of lymph nodes dissected) was statistically significantly higher in patients who died than in patients who survived.In univariate Cox regression analysis, the effects of age, tumour size, estrogen, progesterone, the presence of HER2/neu receptor and axillary metastasis on survival were not determined. We believe that raising awareness on male breast cancer in the community, genetic testing and screening mammography in high-risk patients will be useful in early diagnosis of the disease and improvement of its prognosis.
