ABSTRACT

Diagnosis: Periosteal Chondroma

History: This 41 y.o. woman presented to the Orthopedic clinic with a two month history of a painful mass on her left middle finger. The patient stated that the pain interfered with her work activity; she denied any trauma. The patient was referred to a hand specialist for definitive treatment. Examination 1 month later revealed decreased grip strength in addition to the findings of the initial visit.

Findings: Plain film examination revealed a 9mm x 5mm focal ossific lesion with a chondroid matrix. The mass was adjacent to the cortical surface of the proximal phalanx and demonstrated saucerization of the underlying bone. MRI revealed a well demarcated lesion with a predominantly hypointense signal on both T1 and T2 weighted images, relative to skeletal muscle. A central, linear focus of hyperintense signal was also present on T2 weighted images. The lesion did not communicate with the underlying bone or surrounding soft tissue.

Ddx: • Periosteal chondroma • Periosteal chondrosarcoma • Periosteal osteosarcoma • Bizarre parosteal osteochondromatous proliferation

Dxhow: Resection and Histopathologic evaluation

Exam: On physical exam, she was noted to have a 1 cm firm, fixed, tender mass on the volar aspect of the proximal phalanx with a full range of motion. Sensory examination was within normal limits.

No MeSH data available.
