ABSTRACT

Diagnosis: Bizarre Parosteal Osteochondromatous Proliferation (BPOP)

History: 24 y.o. man presents with mildly painful, hard lump on ulnar surface of left 5th digit. Patient reports traumatic event 4 weeks before clinic visit when he dropped weights on this finger.

Findings: Antero-posterior and oblique radiographs show a well-marginated area of ossification arising from the cortical surface of the ulnar aspect of the 5th middle phalanx. There is no disruption of the cortex and no communication with the medullary canal of the underlying bone.

Ddx: Myositis ossificans Parosteal osteosarcoma Bizarre Parosteal Osteochondromatous Proliferation (BPOP)

Dxhow: Imaging and History

Exam: Notable for firm, fixed palpable mass over ulnar aspect of left 5th middle phalanx. Lesion was mildly tender to palpation without erythema, warmth, or ecchymosis.

No MeSH data available.


Lateral radiograph of the fifth digit of the left hand shows a well-marginated area of ossification arising from the cortical surface of the ulnar aspect of the 5th middle phalanx.  There is no disruption of the cortex and no communication with the medullary canal of the underlying bone.  This is consistent with BPOP.
