Ichthyosiform sarcoisis.

A 39-year-old woman with a 4-year history of paraparesis developed asymptomatic, ichthyosiform scale on her lower extremities. The lesions consisted of polygonal, pigmented, adherent scales, which were most prominent on the pretibial areas. A biopsy specimen showed granulomatous dermatitis in a patient with pulmonary and neurologic sarcoidosis. Ichthyosiform sarcoidosis is a rare, specific cutaneous manifestation of sarcoidosis, which may be responsive to topical or systemic glucocorticoids.
