Mycobacterium abscessus Hand Infections in Immunocompetent Fish Handlers: Case Report.

Abstract

Mycobacterium abscessus hand infections are rare and usually occur in immunocompromised patients or after injection with contaminated injectables. This article describes 2 cases of M abscessus infection of the hand in otherwise healthy fish handlers. Mycobacterium abscessus can cause severe chronic tenosynovitis even in immunocompetent patients and should be suspected alongside the more common M marinum as a cause of nontuberculous mycobacterial hand infections in patients with aquatic and fish exposure.
