Isolated facial cutaneous sarcoidosis.
Isolated cutaneous sarcoidosis is a rare multisystemic granulomatous disorder of unknown etiology. Cutaneous lesions have been classified into specific and nonspecific depending on the presence of noncaseating granulomas on histopathologic studies. Macrophages most likely initiate the response of sarcoidosis by presenting unidentified antigens to CD4+ lymphocytes. A persistent poorly degradable antigen-driven CMI response leads to cytokine cascade, granulomaformation, and fibrosis. In the present study, we report a case of isolated cutaneous sarcoidosis, localized to the face, in an adolescent girl without systemic manifestations which is a rare entity.
