Abstract
We report a case report of lupus vulgaris (LV) presented on the extremities of an 80-year-old man. He was misdiagnosed as having psoriasis and referred to our department for a second-opinion evaluation. The discrepancy between the clinical manifestation which was misleading and the dermatoscopic findings raised the suspicion of an underlying granulomatous disease and we proceeded to skin biopsy. The histopathologic examination set the diagnosis of LV.

Summary
Lupus vulgaris (LV) is the most common form of cutaneous reinfection with M. tuberculosis. LV affects primarily the head and neck region. LV in regions other than the head and neck can pose diagnostic difficulties. We report a case of LV localized on the extremities of an elder patient and we stress the role of dermatoscopic examination
