In 1941, Jaffe, Lichtenstein and Sutro collected a group of similar but variously named synovial lesion of joints, bursae and tendon sheaths and gave them the descriptive title "pigmented villonodular synovitis, bursitis and tenosynovitis". Since then, _numerous reports have appeared which further defined the entity or added series of cases in sufficient number to indicate that the lesion is not uncommon. }
We have experienced a rare case of pigmented villonodular bursitis on bursa anserina.
The patient, who were 36 year old, female, has been complained of painful soft swelling on bursa anserina area of right knee for one year. The excisional biopsy on the affected bursa con-firmed the diagnosis.
