INITIAL SYMPTOMS: Papule usually on the upper extremity; Papule ulcerates and scar tissue develops; Ascending nodular lymphangitis is observed in some patients; [ATS/IDSA Statement: Nontuberculous Mycobacterial Diseases] Mycobacterium marinum is a common nontuberculous mycobacterial (NTM) infection. It is an occupational hazard for aquarium and fish tank attendants and swimming pool cleaners. In some cases, the infection may resemble sporotrichosis with ulcerating papules or nodules that ascend the arm or leg following regional lymphatic vessels. In some cases, deep infections cause tenosynovitis. Patients with AIDS are at increased risk for this infection. [LaDou, p. 288; Guerrant, p. 245-6] M. marinum is one of the common causes of nodular lymphangitis in the USA. Other NTM also cause nodular lymphangitis. [Am Fam Physician 2001;63:326-32] The skin lesion is a chronic nodule, ulcer, or warty growth at the site of a previous abrasion, commonly at the elbow or knee. [PPID, p. 1235] Osteomyelitis has been reported. [ID, p. 2189] Deep infections can involve tendon, joint, and bone. [ABX Guide: Mycobacterium marinum]
