A 62-year-old male patient attended the Gambo Rural General Hospital (Ethiopia) in June 2015 with a two-year history of slowly enlarging, otherwise asymptomatic, superficial black spots on the palms of both hands, light brown with sharp borders, near the wrist of the right hand and a more intense black spot on the center of the palm of the left hand (Figure 1A). A microbiologist performed 10% potassium hydroxide (KOH) examination of scrapings from the lesion, which revealed short septate dematiaceous hyphae (Figure 1B), later confirmed with Papanicolau staining performed by a pathologist with more experience in this type of infections.
