Three cases of successful treatment of granulomatous tenosynovitis

Granulomatous tenosynovitis is a rare disease with an indolent, relapsing process, which can be caused by various pathogens. Here, we describe three immunocompetent patients with right wrist granulomatous tenosynovitis. Two cases were attributed to nontuberculous mycobacteria (NTM) infection. In the third case, no definite etiology was found. However, the symptoms and patient history were similar to the other two cases. All three patients were cured by surgical debridement and clarithromycin-based anti-NTM antibiotics.
