Six patients presented to the dermatology department due to skin abscess of 1 month’s duration. They all underwent a catgut implant procedure at acupoint for treatment of obesity with materials made by the same manufacturer. The patients were treated with ?-lactam antibiotics without improvement. Physical examination of multiple patients revealed numerous warm, red, edematous, tender, fluctuant, and purulent draining nodules on the abdomen (, A). Microscopic examination revealed gram-positive bacilli with positive acid-fast staining and elongated branching morphology identified as Mycobacterium abscessus (M abscessus) by matrix-assisted laser desorption/ionization time of flight mass spectrometry (, B).
