Chondromyxoid fibroma of the zygoma: a case report

Radiological manifestations of chondromyxoid fibroma in the zygoma: A case report and literature review

Chondromyxoid fibroma (CMF) is a rare benign bone tumor of cartilaginous origin, with an extremely rare craniofacial occurrence. Considering its rarity, craniofacial CMF presents a diagnostic challenge for radiologists. To our knowledge, only seven cases of zygomatic CMF have been described in the literature, only one of which was in the paediatric age group. Furthermore, none of the currently reported cases include MRI findings of zygomatic CMF. Here, we present a paediatric case of CMF of the zygoma with a comprehensive literature review of the reported cases, focusing on their radiological features and its differential diagnosis.

Treatment of cryotherapy and orthotopic transplantation following chondromyxoid fibroma of zygomatic bone: A case report

INTRODUCTION

Chondromyxoid fibrotherma (CMF) is a rare benign cartilage tumor that occurs more frequently in young males at the age of 20 to 30. It occurs more frequently on long bones, but rarely involves craniofacial bones.

CASE PRESENTATION

This study mainly introduced a 30-year-old male with CMF of zygomatic bone. Single tumor excochleation was conducted initially. However, CMF reoccurred, and then the following steps were adopted: firstly, the tumor was extensively excised; secondly, in vitro tumor excochleation was conducted; thirdly, the excised tumor bone was placed in liquid nitrogen for 3 cycles of cryoablation; finally, the orthotopic transplantation was performed to reconstruct the zygomatic appearance, with satisfactory follow-up efficacy obtained.

CONCLUSIONS

Orthotopic transplantation after tumorectomy and cryopreservation of tumor bone in liquid nitrogen could lead to excellent therapeutic efficacy and deserves to be widely applied in clinical practice in the treatment of a male patient with CMF of zygomatic bone, because it not only radically eliminates the tumor and kills tumor cells, but also provides bony skeleton for the growth of new bone, thus greatly promoting postoperative aesthetic degree and reducing the occurrence rates of complications.

Chondromyxoid fibroma of zygoma in an elderly patient: A rare presentation

Chondromyxoid fibroma (CF) is a benign bone tumor of cartilaginous origin and is considered the least common of cartilage-derived neoplasms. The lesion's most frequent location is in long bones, while involvement of craniofacial skeleton is extremely unusual. It generally appears in the second and third decade of life and most frequent in men. We present the case of a 68-year-old female with a CF of the zygomatic region. The resection of the tumor and reconstruction of the defect is described.

Chondromyxoid fibroma of zygoma: A rare case report

Chondromyxoid fibroma (CMF) is a rare benign mesenchymal tumor of the bone. Clinically, it is characterized by a lobular growth pattern and histologically by chondroid and myxoid differentiation. The tumor is rare in the craniofacial bones with only 2% of all reported cases. Extragnathic location in the facial skeleton is extremely rare. Most of the cases reported either originate from gnathic sites or in the cranium. A case of CMF in a 3½-year-old male is presented here, which arose from the root of zygomatic arch. A detailed clinical history and histopathological picture of one more case is added to the literature. It is important to document such cases so that better light can be shed on future reviews and conclusions. This shall facilitate better treatment approaches and prognosis. This case is the first reported case of involvement of the zygomatic arch in a pediatric patient.

[An unusual cranial vault tumor: the chondromyxoid fibroma]

Chondromyxoid fibroma is an uncommon benign bone tumor of cartilaginous origin. It is often located in long bone metaphysis. We report a case involving the left frontotemporal cranial vault in a 44-year-old woman. Fifteen cranial vault cases have been reported in the international literature. Surgical resection of the lesion with tumor-free margins is the key factor to cure it and avoid local recurrence.
