Mass on thigh mimicking soft tissue tumor – a rare case report
Abstract
Hidradenoma papilliferum (HP) is a rare benign, cystic, papillary, apocrine gland tumor that occurs mostly in females on the anogenital area. Rare cases of ectopic (non-genital) HP have been described. These ectopic tumors are seen at various sites and are more common in women. These lesions usually present as asymptomatic slow-growing, red, firm, mobile, well-defined nodule that grows for a long time before resection. The prognosis for HP is very good. Incomplete excision of tumor resulted in tumor recurrence. Malignant transformation is rare. We present a case of 65-year-old man who presented with an enlarging nodule on his left thigh. The histological findings and immunohistochemistry revealed a Hidradenoma papilliferum.
