Lichenoid sarcoidosis in a 3-year-old girl

We report a case of lichenoid sarcoidosis in a 3-year-old girl. She had numerous discrete skin-colored or erythematous, infiltrated follicular papules on the buttocks and extremities since 2 months of age. Histopathologic examination showed follicular plugging and an upper dermal granulomatous infiltrate of epithelioid cells closely surrounding the follicular ducts. No acid-fast bacilli were seen in the sections examined. Chest radiograph and high-resolution computed tomography (CT) showed no hilar lymphadenopathy or pulmonary parenchymal changes. An angiotensin-converting enzyme level was elevated. The Mantoux reaction was negative and results of ophthalmologic examinations were normal. Treatment was started with triamcinolone 0.2 mg/kg and prednicarbate ointment. Some lesions healed completely and others showed residual pitting.
