To the Editor.—
There are a large number of epidermal appendage tumors of the skin, and they have been carefully classified according to clinical appearance, light and electron microscopical structure, and enzyme histochemistry.1,2 Most of these tumors appear to be acquired and are representative of developmental defects, although disorders such as the basal cell nevus, trichoepithelioma, cylindroma, and steatocystoma multiplex have a genetic basis, and they are inherited in an autosomal dominant manner.3 Of these disorders, however, in only the basal cell nevus syndrome is a second type of skin lesion—palmar keratoses and pits—observed. This report describes a patient with both syringomas of the face and palmar keratoses, whose mother had similar lesions.
