摘要

Mycobacteria are aerobic, non-spore forming, gram positive, acid-fast bacilli, which affect skin, subcutaneous tissue,and other organs and systems. Mycobacterium fortuitum produces cellulitis, abscesses, papules-pustules, nodules andulcers with serosanguinolent, purulent material, and subcutaneous necrosis. A 61-year-old woman, presents a case oftwo months of evolution that begins with reddish grain from an insect sting. After immersion in the Mexican Sea, itworsens, increases in quantity, is blistered and has brownish secretion; Physical examination shows erythematous plaque,with punctate orifices with hematic and meliceric crusts; Pustules and satellite papules, on the anterior aspect of theright leg. Histopathology: Suppurative dermal granulomas, centered by acute leukocyte infiltrate, with liquefactivetissue necrosis, surrounded by chronic inflammation with macrophages, plasma cells, lymphocytes, multinucleatedgiant cells. The first skin culture returns negative; in the second skin culture, fast-growing, non-pigmented atypicalmycobacteria. Molecular detection is performed by Polymerase Chain Reaction: Mycobacterium fortuitum. Treatmentwith Ciprofloxacin 500 mg every 12 hours, with resolution of the table to the eighth month. A case of cutaneousinfection by Mycobacterium fortuitum, related to the immersion in the sea and corals, whose diagnostic process hasbeen difficult and was achieved by techniques of advanced molecular biology.
