A case of Darier-Roussy sarcoidosis
Keywords:
Subcutaneous sarcoidosis, Tuberculosis, Interferon-γ release assay (IGRA)Abstract
Subcutaneous sarcoidosis, a rare form of cutaneous sarcoidosis, is seen in approximately 4.3-12.1% of patients with systemic sarcoidosis. These lesions are often associated with less severe systemic disease and usually appear at the beginning of the disease. The present study discusses an unusual case of subcutaneous sarcoidosis with interferon-γ release assay (IGRA) positivity. The case report highlights the increased chances of misdiagnosis of Darier-Roussy sarcoidosis as tuberculosis based on positive IGRA, especially in countries with increased prevalence of TB.
