Description

A 75-year-old man had had a mass on his right buttock for about 10 years. The mass developed slowly, and he visited a private clinic of a plastic surgeon. According to the clinical record, a 9×8 cm infected mass on the right buttock was incised, drained and also biopsied. The biopsy specimen of the mass showed the existence of squamous cell carcinoma, and he was referred to our hospital. Physical examination revealed that there was a 6×4 cm mass on his right buttock. Image inspection results suggested swelling of the right inguinal lymph node. We performed a wide excision of the tumor. Histopathological examination of the resected tumor showed a cystic structure and highly differentiated squamous cell carcinoma connected to the cyst wall. The tumor had infiltrated into the subcutaneous tissue. Metastasis was found in one lymph node.[Skin Cancer (Japan) 2013 ; 28 : 292-296]
