We report the a case of Nora's lesion (Bizarre Parosteal Osteochondromatous Proliferation) of the sesamoid. A 32-year-old woman presented with a painless, enlarging mass of two years duration on the plantar aspect of the first metatarsophalangeal joint of the left foot. Radiographs, Computerized Tomographs and Magnetic Resonance images, initially suggested a parosteal osteosarcoma arising from the tibial sesamoid. The mass was excised, and a histological diagnosis of Bizarre Parosteal Osteochondromatous Proliferation of bone (Nora's lesion) was made. The aggressive growth of this lesion may suggest a neoplasm clinically. Histological features, however, are those of a reactive lesion.

Histopathologic Findings

Extraskeletal chondroma is defined as a rare, benign, cartilaginous tumor arising from soft tissues such as tendons, tendon sheath synovia, and joint capsules with no continuity to the periosteum or bone cortex. In histopathologic findings, the tumor exhibits many lobular structures and some parts similar to hyaline cartilage. Therefore, it is sometimes difficult to differentiate this tumor from low-grade chondrosarcoma because of their similar histopathologic findings. In order to prevent recurrence, it is necessary to remove the tumor as a whole, including the capsule, so as not to leave any remnants of the tumor. In this article, we report our treatment experience with a case of extraskeletal chondroma in the index finger of a 63-year-old patient.
