ABSTRACT
Protothecosis is a primary or opportunistic chronic infection caused by achlorophyllic algae of the genus Prototheca. These algae enter through minor trauma or surgical incisions. Protothecosis is a uncommon disease with clinical manifestations that vary and with systemic, cutaneous, subcutaneous and bursal involvement. It is diagnosed without difficulty by histopathology and culture. There is no specific treatment. However, triazolic derivatives combined with surgery yield good results.
