Subcutaneous nodular sarcoidosis and systemic involvement successfully treated with doxycycline.

Subcutaneous nodular sarcoidosis is a rare cutaneous manifestation of systemic sarcoidosis. We report a new case in a 45-year-old woman with a 7-year history of subcutaneous nodules and a new onset of dyspnea. She was treated with corticosteroids but her disease recurred upon withdrawal. A 6-month course of doxycycline in a dose of 200 mg/d led to complete remission. We also emphasize the value of systemic work-up and regular screening in such cases.
