Abstract

Cutaneous manifestations in sarcoidosis are seen in 25-35% of patients with systemic disease and may be the sole manifestation in few patients. It is known that isolated cutaneous sarcoidosis is a great mimicker and can be easily misdiagnosed as other granulomatous conditions especially lupus vulgaris in regions with high burden of tuberculosis (TB). Here we present a case with cutaneous sarcoidosis who was initially misdiagnosed and treated as bifocal lupus vulgaris with antitubercular therapy (ATT) for 6 months. This nonresponsiveness to therapy prompted us to investigate the patient further for other differentials, failing which a diagnosis of cutaneous sarcoidosis was made and the patient was treated with oral steroids and methotrexate with complete clearance of lesions after 14 weeks of therapy. Our case reemphasizes the value of therapeutic trial of ATT in diagnosis of cutaneous TB and highlights the remarkable clinical mimic of sarcoidosis with lupus vulgaris.
