Osteochondroma at its rarest site.
BACKGROUND
Osteochondromas usually arise from the metaphyseal region of the growing skeleton but extraskeletal cartilaginous tumors are rarest.


METHODS
A 65 year old woman presented with anterior knee pain and inability to flex her knee more than 90° since 1 year. Clinical examination and imaging studies revealed a nodular calcific mass in the anterior portion of the knee i.e. patella. Following excision, histopathology confirmed the diagnosis of extra-osseous osteochondroma-like soft tissue mass, with no recurrence in 36 weeks.


CONCLUSIONS
An integrated clinical-pathologic diagnosis helps to clarify the nature of extraskeletal cartilaginous tumors that can arise at unusual anatomic site viz. patella. Complete local surgical excision is the management of choice.
