Generalized hair follicle hamartoma: the third case report in association with myasthenia gravis.

A 29-year-old woman, referred because of the development of diffuse papules and plaques on the face and progressive hair loss, was found to have generalized hair follicle hamartoma, a very rare condition previously described in only two female patients. All three patients also suffered from myasthenia gravis. The histological appearance of both the involved and uninvolved skin was similar to trichoepithelioma.
