Osteochondroma of the phalanx: a late Roman case

Solitary osteochondromas in paleo-oncology: A case report from 4th-century BCE Pontecagnano (southern Italy)

OBJECTIVE

This study presents a new case of solitary osteochondroma (SOC) identified on the proximal tibia of a 4th-century BCE individual from Pontecagnano (Salerno, Italy) with an aim to contribute to differential diagnosis of bone tumors in archeological contexts.

MATERIALS

Paleopathological assessment of a male individual with an estimated age-at death of 45.9-62.9 years brought to light during the archaeological excavations in the funerary sector of 'Sica de Concillis' within the necropolis of Pontecagnano.

METHODS

Macroscopic and radiographic analyses were performed for diagnostic purposes.

RESULTS

The proximal portion of the right tibia exhibited a large exophytic bone formation extending from the anteromedial to the posteromedial portion of the diaphysis. The x-ray confirmed the lesion being characterized by regular trabecular bone tissue with cortico-medullary continuity.

CONCLUSIONS

The lesion observed is diagnostic of sessile SOC, a neoplasm that must have had aesthetic and, possibly, neurovascular complications due to its large size.

SIGNIFICANCE

By offering a detailed description of a case of tibial osteochondroma and discussing the possible complications the individual might have experienced during life, this study highlights the role and importance of benign bone tumors in paleo-oncology.

LIMITATIONS

Histological analysis was not carried out in order to preserve the integrity of the affected tibia.

SUGGESTIONS FOR FURTHER RESEARCH

More attention should be devoted to benign tumors in paleopathology as their occurrence and manifestations in the past will lead to a better understanding of their impacts on the quality of life of affected individuals and to greater knowledge of their natural history.

Solitary intra-articular osteochondroma of the finger

BACKGROUND

A solitary osteochondroma of the finger occasionally occurs intra-articularly and may cause clinical symptoms, including limited motion and deformity. The present report describes the clinical features and the results of operative treatment for a series of patients who had a solitary intra-articular osteochondroma of the finger.

METHODS

Ten patients with a solitary intra-articular osteochondroma of a phalanx of a finger were managed surgically. Eight patients were male, and two were female. The average age at the time of surgery was fourteen years. Treatment consisted of mass excision for three patients and mass excision with corrective osteotomy for six. One additional patient had a boutonniere deformity and underwent extensor tendon reconstruction combined with mass excision. The average duration of follow-up was forty-four months.

RESULTS

The proximal phalanx was affected in six patients, and the middle phalanx was affected in four. All tumors involved the distal epiphysis. All patients had postoperative improvement in terms of deformity and/or limitation of motion. Six patients had a preoperative mean coronal plane deformity of 29 degrees, which improved to 4 degrees after surgery. The preoperative mean arc of flexion-extension improved from 54 degrees to 78 degrees in four patients who had a motion deficit at the proximal interphalangeal joint and from 60 degrees to 80 degrees in one patient who had a motion deficit at the distal interphalangeal joint. Two patients had a residual flexion contracture, one with preexisting osteoarthritis and one with a longstanding progressive boutonniere deformity. There were no other complications or recurrences.

CONCLUSIONS

Isolated intra-articular osteochondroma of the finger can cause deformity and/or motion limitation. Early mass excision and corrective osteotomy when indicated are recommended to restore full range of motion and to prevent osteoarthritis and secondary deformity.
