An unusual presentation of mycetoma around knee joint as a subcutaneous mass - A case report.

Abstract

Mycetoma is a form of chronic granulomatous disease which involves subcutaneous tissues and causes bone destruction in advanced stages. The characteristic features are sinus formation, granules formation, and mass in subcutaneous region. A 19-year-old male presented to our out-patient clinic with complaint of a painless swelling around the medial aspect of the right knee joint for 8 months with no sinus or discharge of granules. Pes anserinus bursitis was thought of as differential diagnosis for the present condition. "Staging-classification of mycetoma" is commonly used for classifying mycetoma and as per classification, the present case had Stage-A. Single-stage local excision was performed and supplemented with anti-fungal agent for 6 months, which showed good outcome at the final follow-up of 13 months.
