Atypical presentation of adenosquamous carcinoma: A case report

Cutaneous adenosquamous carcinoma is a rare malignant neoplasm that is more aggressive than conventional squamous cell carcinoma. The typical clinical presentation is an indurated papule or plaque on the head and neck of elderly patients. The authors report the case of a 52-year-old man with a right scrotal and inguinal tumour measuring 10 cm × 15 cm that had progressed over the past 2 years. The histological examination was compatible with adenosquamous carcinoma. Metastatic inguinal and pelvic lymph nodes were identified. This case demonstrates an atypical presentation of a rare tumour. Adenosquamous carcinoma is more aggressive than conventional squamous cell carcinoma, and prompt diagnosis is important.
