Swimming Pool Granuloma

Swimming pool granuloma is an uncommon skin infection caused by a mycobacterium present in the water of pools, aquariums, and other aquatic environments. It enters through small cuts or scrapes in the skin.

Common symptoms: one or several reddish nodules or lesions that appear weeks after contact, usually on the hands, elbows, or knees, and that may progress slowly.

Common causes: it is associated with the contact of injured skin with contaminated water, so it is common in people who clean aquariums or frequent pools.

Which specialist treats it? Its evaluation is handled by the dermatologist, with support from the general surgeon in some cases and initial guidance from the general practitioner. If a skin lesion persists after contact with water, it is worth showing it to a professional for evaluation.
