Metastatic cutaneous leiomyosarcoma from primary neoplasm of the mesentery

A 31‐year‐old South Korean woman was referred to the dermatology department from the oncology department for the evaluation of a subcutaneous nodular lesion on the back. Three years before, she noted a palpable, fingertip‐sized, nontender mass on her right lower abdomen. The mass had increased in size slowly. One year ago, she visited a local clinic and physical examination revealed a 7 × 8 × 7 cm, slightly tender, deep‐seated mass on the right lower quadrant of the abdomen. The mass on the ilial mesentery was resected by surgical exploration and tissue examination revealed leiomyosarcoma. She refused adjuvant chemotherapy.
