Genital tumors: their management by micrographic surgery.

Genital tumors represent a special group requiring effective and curative treatment while functional and cosmetic demands require tissue sparing techniques. For these reasons, micrographic surgery is indicated. Over the past 5 years we have treated 24 such patients utilizing standard techniques for micrographic surgery. The patient population included twenty male and four female patients with ages ranging from 27 to 80 years. Histologically confirmed diagnoses included squamous cell carcinoma, Bowen's disease, verrucous carcinoma, basal cell carcinoma, Paget's disease, and leiomyosarcoma. These were located on the penis, scrotum, perineum, and buttocks. Seven of these patients were considered to have recurrent tumors. Preexisting conditions existed in 6 patients, including balantis xerotica obliterans, trauma, decubitus ulcer, and hidradenitis suppurativa. All surgery was performed under local anesthesia in the cutaneous surgery unit. Average pretreatment tumor size was 2.0 X 1.9 cm. Average postoperative defect size was 4.5 X 3.7 cm. Tumors were excised with an average of three stages and 18 sections. Most defects (65%) were allowed to heal by secondary intention, five (21%) were closed primarily, and three were referred for closure. After surgery five patients developed metastases in their regional lymphatic system. No patients developed local recurrence. Micrographic surgery is a most useful treatment modality in patients with genital tumors for control of local disease. However, patients with squamous cell carcinoma should be considered for elective regional lymph node biopsy and/or dissection in conjunction with micrographically controlled excision of the primary tumor.
