Abstract
The patient was a 58-year-old woman. We resected squamous cell carcinoma (SCC) about 4 cm in size from her forearm with a 2 cm margin of tumor free skin, and performed a sentinel lymph node (SLN) biopsy. Histopathological examination revealed no evidence of SLN metastasis. Since 8 months after the surgery, she had not visited our hospital. Two years after the surgery, she noticed that the tumor had gradually increased to her elbow. When she visited our hospital, there was an erosive tumor, 20cm in size. We diagnosed in-transit metastasis of SCC, transected her right superior limb from the shoulder joint and right axillary lymphadenectomy. Histopathological examination revealed no evidence of SCC and axillary lymph node metastasis. Peplomycin sulfate preoperatively, 7-courses of CDDP and 5-FU postoperatively were used for systemic chemotherapy. The patient has no sign of recurrence. [Skin Cancer (Japan) 2006; 21: 332-335]
