[Perineal tumors in male patients]

Perineal tumors are rare and are malignant primaries in 66% of cases. We treated three patients with perineal tumors. Histological examination led to a diagnosis of benign tumor (lipoma, granulomatous tumor) in two patients and a diagnosis of local perineal metastasis of a malignant nonseminomatous germ cell tumor in the third. After local tumor excision all patients stayed free of disease for 1-3 years. Neither physical nor clinical examination (standard blood parameters, ultrasound, X-ray of pelvis, urethrocystoscopy and rectoscopy) allowed determination before surgery of whether any of these perineal tumors was benign or malignant; percutaneous biopsy was the only way to find this out preoperatively. Radical excision of the perineal tumor is the treatment of choice. If extended dissemination has not taken place, malignant perineal tumors are curable by radical resection in nearly 80% of cases.
