Abstract The number of
skin infections caused by
atypical mycobacteria has increased in recent decades. They usually appear after contact with
wounds and interruptions in the integrity of the
skin. The present
report describes a case of cutaneous
infection by
Mycobacterium marinum, in a young, immunocompetent
patient, with a prolonged evolution, diagnosed through a
skin lesion
culture (from a spindle
biopsy of the
skin). The
patient was treated with multidrug
therapy, including
clarithromycin,
doxycycline, and
rifampicin, due to the lesion extent, with satisfactory results. A brief
review of the
literature is also provided.
