History

Figure 1
Translucent-appearing tumor of the groin

A 68-year-old man presented with a protruding mass in his groin. He had worked as a blacksmith for fifty years. Thirty-five years ago he had a similar groin lesion biopsied in another hospital. It was diagnosed as "glandular epithelioma". He received soft X-ray therapy. The lesion reappeared five years later, and he was treated with cobalt radiation, with good results. Five years ago a basal cell carcinoma on the back was excised at our hospital. He did not return for follow-up until a slowly growing lesion on his groin, present for the last three years, brought him for consultation. Physical examination revealed a poikilodermatous area on his right groin, with a sessile, translucent-looking, soft tumor, not fixed to deep structures. He also had a lesion on his back diagnosed as Bowen's disease, and a superficial multifocal basal cell carcinoma on his thigh. General physical examination was normal.

When cut for processing, the groin tumor was described as multinodular, with waxy and violaceus areas. It oozed a mucinous substance.

Laboratory

The following results were negative or normal: Hemogram, biochemistry, chest-X-ray, barium enema, upper gastrointestinal series and thoracoabdominal computerized tomography. Electroneuromyography showed no signs of polyneuropathy. Arsenic levels in nails and pubic hair were normal.
