MACEDO, Priscila Marques de et al. Dermatomyofibroma: a case report of a rare disease. An. Bras. Dermatol. [online]. 2011, vol.86, n.1, pp.120-123. ISSN 0365-0596. http://dx.doi.org/10.1590/S0365-05962011000100016.
Dermato myofibroma is included in the group of benign cutaneous mesenchymal neoplastic lesions of fibroblastic and myofibroblastic lineage. It's a rare disease and there are approximately only one hundred cases described worldwide in the medical literature up to now. The present study reports the case of a young woman with typical clinical cutaneous lesion and histopathological diagnosis of dermato myofibroma. Special stains were carried out which showed preserved collagen fibers and immunohistochemistry was positive for vimentin and negative for actin and S100. As it is a rare disease, the histopathological findings are of great importance but clinical suspicion is possible in typical cases such as this one.
