Giant-cell tumor (GCT) of bone is a primary bone neoplasm which is most commonly seen around the knee joint. Curettage and bone grafting is the mainstay of treatment in GCT. However, local recurrence is a frequent complication. Osteochondroma is a common benign tumor, which arises from a developmental defect in the growth plate. A para-articular osteochondroma is a rare lesion with only a few reported cases in the literature. This case is presented as, in the literature survey, we were not able to find any case where a GCT and para-articular osteochondroma occurred in the same patient. Furthermore, a superimposed Idiopathic Thrombocytopenic Purpura was detected and treated before her second "primary" operation.
