Sebaceous hyperplasia: a clue to the diagnosis of dermatofibroma.
We describe a man with an indurated lesion on his upper back that showed a dermatofibroma with overlying sebaceous hyperplasia. Characteristic dermal features of a dermatofibroma may be sparse or absent in a lesional specimen that has been submitted subsequent to a superficial shave biopsy. Hyperplasia of sebaceous glands in a nonfacial lesion is a histologic feature that should prompt the search for a dermatofibroma in the underlying dermis.
