Acromelanosis. A case report.
The case of a 2-year-old Puerto Rican boy is presented. Clinical and histologic features are detailed because he showed peculiar jet black patches of pigmentation on the fingers of the right hand. This case, except for the lack of progression of the disease after a 2-year period of follow-up, shows many similarities to the case of a Japanese child reported by Furuya and Mishima as "acromelanosis progressiva." This condition is viewed as the epidermal counterpart of pigmentary disorders composed of dermal melanocytes, "epidermal melanocytosis."
