[Ileal and axillary metastasis of primary unknown site melanoma. Clinical case].

The incidence of Cutaneous Melanoma is 4-5% of all the tumors of the skin. This incidence increases several folds in the last years. Metastases of Melanoma involve lungs, skin, soft tissue, liver, bone, brain, but in 20-30% of the patients involve gastrointestinal (GI) tract. In 60-70% of the cases GI metastases involve small bowel, in 15-20% stomach, in 10-20% large bowel, in 5% esophagus. In 8% of the patients the primary cutaneous melanoma is not known. The prognosis of the patients with metastatic melanoma is poor with an average survival of 5 months. One patient male, 51 years old, underwent surgery for metastases from melanoma in the lymph nodes of the right axilla and in the gastrointestinal tract (ileum). An ileo-ileo anastomosis and a lymphoadenectomy of the nodes of the right axilla were performed. After a first chemotherapy with DTIC (800 mg/m2) + a-IFN(3MU three times every week) and another with CDDP (30 mg/m2 day 1-3), DTIC (250 mg/m2 day 1-3) and VDS (2.5 mg/m2 day 1) with no response, the patient was treated with chemo-immunotherapy sec. Bernengo, slightly modified: CDDP 75 mg/m2; IL-2 18 MU (9MU b.d.) day 3-6 and 17-21; a-IFN 5MU three times every week. This therapy had a partial response of short-course (three months) and the patient died 15 months after surgery. The authors hope that immunotherapy and genetic therapy improve the survival of the patients with metastatic melanoma in the next years.
