title: Cylindroma of the breast in a 72-year-old woman with fibrocystic disease first misdiagnosed as a malignant lesion in imaging studies.
abstract: Cylindroma is a benign skin adnexal tumour with apocrine and trichoepitheliomatous differentiation that is rarely seen in the breast. Here, we report a case of cylindroma in the subareolar region of the left breast in a 72-year-old woman who presented with a palpable mass. Ultrasound and mammographic reports of the lesion were considered probably malignant. An ultrasound-guided core needle biopsy was performed and the patient underwent wide local excision with axillary lymph nodes biopsy. Immunohistochemistry and histopathological studies confirmed cylindroma with fibrocystic changes in uninvolved parenchyma.
