Juxtacortical Chondroma of the Hand: Treatment by Resection of the Tumour and the Adjacent Bone Cortex

A recurrence of a juxtacortical chondroma of the finger after marginal excision prompted us to review the treatment of this condition. Although the recommended treatment is simple curettage or marginal excision, the reported recurrence rate is significantly higher for lesions in the hand than those in other locations and recurrences only occurred in patients who had local treatments which did not include excision of the adjacent bone cortex.

We report five patients with juxtacortical chondroma of the fingers. The first patient underwent marginal excision without resection of the underlying bone cortex. The other four patients underwent intralesional, marginal or wide excisions of tumour with resection of the bone cortex underlying the lesion. Recurrence was only seen in the patient who did not undergo resection of the bone cortex. Resection of the underlying bone cortex after excision of this tumour may be advisable for the treatment of this tumour in the hand to reduce the rate of recurrence.

Periosteal chondroma of the femur: A case report and review of the literature

Periosteal chondroma is a rare benign cartilage tumor located on the cortical bone, which may be mistaken clinically and histologically for other and more common tumors in this location. The current study reports the case of periosteal chondroma located in the distal femur of a 14-year-old female. A non-tender swelling, 5×4 cm in diameter, was identified on computed tomography, a radiological study of which revealed an overhanging edge and a radiolucent shadow with stippled calcification in radiographs and a lobular heterogeneous mass in magnetic resonance imaging. Cytological examination of the excision biopsy revealed cellular pleomorphism and binucleate cells. The patient underwent en bloc resection of the tumor and covering periosteum, and the histological diagnosis was subsequently determined to be periosteal chondroma. The present study also reviews nine previously reported cases of periosteal chondroma in the femur, with a discussion of the demographic characteristics, imaging features, differential diagnosis and treatment of bone tumors in this location. This study aims to inform clincians that periosteal chondromas may occur in the distal femur although osteochondromas are more common and to discuss making a differential diagnosis between periosteal chondroma and other bone tumors.

A report of a rare phalangeal periosteal chondroma of the foot

Periosteal chondroma is a benign, slow-growing cartilaginous tumor that typically occurs at the metaphysis of long tubular bones beneath the periosteal membrane. A case is presented of a 42-year-old male who developed a firm, tender, uneven mass encircling the lateral, dorsal, and medial aspects of the right second proximal phalanx following a traumatic event. The mass was excised en toto and histopathologic findings are presented.

Periosteal chondroma with atypical behavior in a 9-year-old black female: case report

Periosteal chondroma is an uncommon benign cartilaginous tumor of bone reported most often in children and young adults but is as of yet unreported in a black child. This is a case of periosteal chondroma in a 9-year-old black female with unusual findings of short duration of symptoms; large size; suspicious x-ray appearance and; aggressive behavior. The lesion was histologically benign and has not recurred six years post curettage.
