Childhood cutaneous leiomyosarcoma.

Cutaneous leiomyosarcoma is a soft tissue neoplasm exhibiting an aggressive local behavior and a potential for distant metastases. It is rare during childhood and diagnosis can be challenging both clinically and histologically. Surgical excision with wide lateral and deep margins is the treatment of choice, whereas radiotherapy and chemotherapy are contraindicated.
