A Case of Cutaneous Sarcoidosis with Direct Osseous Involvement

Sarcoidosis is a granulomatous disorder that presents with cutaneous manifestations in one-third of patients, often as an initial symptom prompting interaction with the healthcare system. Here, we report a case of cutaneous sarcoidosis on the forehead with directly underlying erosive osseous disease. The patient was imaged further, uncovering pulmonary involvement. The lesion was treated with topical and intralesional corticosteroids with significant resolution. Though there exist a range of classic eruptions associated with sarcoidosis, skin involvement can present variably and should prompt additional imaging, particularly to assess for osseous and pulmonary involvement. Topical and intralesional corticosteroids can be effective first-line therapy for cutaneous sarcoidosis.
