Dermatomyofibroma: case report and review.

This case report describes a 4-year-old boy with a dermatomyofibroma on the posterior aspect of the neck. Dermatomyofibroma is a recently described, rare, benign proliferation of myofibroblasts of the skin, mainly found in young women. Only a few cases have been reported in males. This entity is not generally well known and probably often misdiagnosed. To our knowledge the patient presented here is the youngest diagnosed thus far.
