Abstract:
The authors report the case of a 44-year-old man in whom a poorly differentiated primary carcinoma of the head of the epididymis was discovered incidentally. Due to the rarity of this diagnosis, a comprehensive assessment was performed looking for a primary tumour, but without success. Despite early surgical resection, the patient developed lymph-node metastases. This exceptional tumour showed low sensitivity to chemotherapy. Malignant tumours of the epididymis are exceptional and require investigations to detect a primary tumour. Treatment is based on surgical resection, ideally via an inguinal incision, combined with chemotherapy adapted to the histological type.
