Progressive eruptive histiocytomas

We describe progressive eruptive lesions that have been appearing on a 50-year-old Filipino man for the past 9 years. They are characterized by smooth, brown, firm nodules mainly on the head and torso. Histologic examination shows dermal collections of lipid-filled histiocytes and Touton-type giant cells. A comparison with other types of previously described non-Langerhans cell histiocytoses is made.
