Introduction:

Cutaneous sarcoidosis is a chronic inflammatory disease of unknown etiology. Its most common manifestations include erythema nodosum and the formation of papules, nodules, and plaques. The literature describes cases of successful treatment with phototherapy.

Objective:

The purpose of this study is to present the case of a patient with cutaneous sarcoidosis who achieved complete remission of lesions following PUVA phototherapy.

Case report:

A 51-year-old woman presented to the Dermatology Outpatient Clinic with erythematous and papular lesions on her back. Histopathological examination revealed nodular collection of epithelioid histiocytes in the dermis with sparse lymphocytes at the periphery corresponding to sarcoidosis. Due to the ineffectiveness of potent topical corticosteroids, PUVA phototherapy was implemented. After a cycle of 20 irradiations, complete remission of the skin lesions was achieved.

Conclusions:

Cutaneous sarcoidosis presents a diagnostic and therapeutic challenge. PUVA phototherapy may be an effective therapeutic option.
