Aquarium granuloma: a diagnosis based on history

Chirag Pereira, Leo F. Tauro, Prathvi Shetty


Mycobacterium marinum infections are rare but well described in literature. It causes an infection known as aquarium granuloma or swimming pool granuloma since its transmitted through contaminated water. We describe a case of aquarium granuloma in a male patient with skin nodules over his dominant hand whose occupational history helped clinch the diagnosis.
