Apocrine gland carcinoma on the right thigh
Abstract
The authors report a case of cutaneous apocrine ductal carcinomaof the right thigh in a 78-year-old female. Histological examinationrevealed a solid, ductal and glandular tumor with a significantdesmoplastic reaction. The tumor cells showed high-grade cellularatypia, and occasional peritumoral inflammatory infiltration wasalso observed. There were no characteristics of extramammaryPaget´s Disease on the overlying skin. The neoplastic cells wereimmunohistochemically positive for S-100 protein, lysozyme andalpha-chymotrypsin, but negative for CEA, EMA, and HMB-45. On thebasis of these findings, the diagnosis of apocrine ductal carcinomawas confirmed. The patient then underwent wide resection of thetumor plus en-bloc radical inguinal lymphadenectomy. The localreconstruction was done by means of a tensor fascia lata flap, noadjuvant treatment was performed. To date, one year on, the patientremains healthy, there being no evidence of tumor recurrence.
