Atypical Breast CarcinomaA Series of Six Cases

Abstract

Breast cancer comprises 10.4% of all cancer among women world and it the second most common type of cancer. Increased public awareness and screening have led to earlier diagnosis at different stages. Surgical resection can be done earlier and complete cure of the disease can be achieved. As a result survival rates for breast cancer in young women have improved significantly. Six unusual type of breast carcinoma, presented to the Surgery Outpatient Department were referred to Pathology Department for further investigations. Patient age and sex, clinical characteristics of the tumour, the duration of the lesion, the size, radiological investigation, Fine Needle Aspiration Cytology (FNAC), trucut biopsy and histopathological examination were noted. Immunohistochemical examination also done in all the cases. Out of the six cases of breast carcinoma, one was the mucinous carcinoma of breast, two invasive papillary breast carcinoma, one apocrine carcinoma, one invasive Pleomorphic Lobular Carcinoma (PLC) of breast and one was fibromatosis like metaplastic carcinoma of breast. All the patients were female except, a 71-year-old male who presented with invasive papillary carcinoma. All the female patients were presented at postmenopausal age group. After careful examination of the cytology and histopathological slides the final diagnosis was made which helped the clinician for further treatment. Rare breast cancers do not differ from other types of breast cancer in their presentation. But they vary by treatment regimens and outcomes. So, proper diagnosis with imaging, FNAC, trucut biopsy and histopathological examination is a combined tool for proper diagnosis and treatment.
