Eumycetoma on histopathology presenting at unusual site: A rare entity.

Rajan Shah, Smriti karki, Ujawal Rai, Shankar Kafle



Mycetoma, an uncommon chronic infection of skin and subcutaneous tissues commonly seen in tropical and subtropical countries. It is caused by true mycetes named eumycetoma and filamentous bacteria belonging to group actinomycetes. The incidence is more common in agricultural workers walking in bare foot. Foot is most commonly affected. Other less commonly affected sites includes hand, knee, chest and head and neck region. Both forms of mycetoma present as a progressive, subcutaneous multiple nodular swelling with discharging sinuses containing black colour granules. The treatment of these two etiologies is entirely different, a definite diagnosis after histopathological examination is mandatory. We here by present a case of eumycetoma affecting knee joint.
