Subcutaneous nodules with sporotrichoid spread.
BACKGROUND
Mycobacterium marinum is an atypical mycobacterium found worldwide and associated with swimming pools and aquariums. Infections typically present with subcutaneous nodules and lymphangitis.


METHODS
A 61-year-old female presented with a two-month history of subcutaneous nodules. The patient had a significant recent history that included rose gardening and cleaning her aquarium at home. Biopsy for histology and tissue culture proved the presence of infection with Mycobacterium marinum and the patient was treated with minocycline. The nodules eventually healed and no new lesions appeared after initiation of treatment.


CONCLUSIONS
Mycobacterium marinum is one of many entities that must be considered in a patient with ascending nodules along the lymphatic drainage of an extremity.
