Desmoplastic cutaneous leiomyosarcoma: case report and review of the literature.

abstract：BACKGROUND:Studies on the precise cause of increased melanization in pigmented basal cell carcinomas (BCC) are limited. We aimed to determine whether the cause of melanization is from increased number of melanocytes or increased melanin pigment, and if there is a difference in the number of melanocytes on different sun...
