Left Buttock Sebaceus Carcinoma: A Case Report and Review of the Literature

Sebaceous carcinoma is a rare, aggressive, malignant tumour, characterized by a tendency for local recurrence and distant metastases. This case report presents a rare form of sebaceous carcinoma in an 86 years-old female. Clinical examination revealed a 12cm nodular tumour, yellow-brown in colour, located on the left buttock of the patient. Ultrasound examination indicated that no ganglions were affected; dermatological examination suggested that the tumour had an unpredictable evolution. Treatment was surgical with a 2cm wide excision, followed by reconstruction with a VY skin flap, from the left side of the buttock. Histological exam supported the diagnosis of sebaceous carcinoma; the tumour was removed with a safety margin of healthy tissue. Sebaceous carcinoma is a malignant tumour with unpredictable evolution. Diagnosis is based on histological examination. Treatment of choice consists in complete wide surgical excision.
