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.


Lateral radiograph of the left long finger shows an oval, calcified mass anterior to the distal aspect of the proximal phalanx, with extrinsic saucerization of the underlying cortex.
