Chondromyxoid fibroma of the mandible

Chondromyxoid Fibroma of the Mandible in an Adolescent: Case Report and Microsurgical Reconstructive Option

Chondromyxoid fibroma is a rare bony tumor that usually presents in the lower extremities of middle-aged adults. Involvement of the craniofacial skeleton is extremely rare. We present the unique case of an adolescent boy with a chondromyxoid fibroma of the mandible. The chondromyxoid fibroma in this patient recurred after initial treatment with curettage. We treated the recurrence with resection of the involved mandible and immediate reconstruction using a vascularized musculo-osseus seventh rib flap (“Eve procedure”). Despite complex reconstruction in adolescents due to skeletal immaturity, the rib flap has successfully grown with the patient up to 3 years postoperatively. Therefore, we believe the musculo-osseus rib flap is a feasible solution for complex ramus and condyle reconstruction of the growing mandible in the adolescent patient.

Unilocular anterior mandibular swelling

PURPOSE

To report a rare case of chondromyxoid fibroma, presenting as an unilocular anterior mandibular swelling, which is one of the least common tumours of bone comprising less than 1% of bone tumours and to review the differential diagnosis and literature for a better understanding of this disease as well as addressing the controversies in respect with its treatment.

MATERIALS AND METHODS

Previous reports about this lesion in literature were reviewed wherein data was recorded about the age, sex, race, location of pathology, presenting signs and symptoms, duration of pathology, size, radiographic findings, treatment and any recurrence on follow-up.

RESULTS

25 cases were studied and data compiled. Multisectional histopathological examination is advocated to differentiate it from osteosarcoma. Enucleation with or without curettage with long-term follow-up has been considered to be a satisfactory treatment modality.

CONCLUSION

The rarity of the lesion, limited data on the clinical presentation, histological dilemma and treatment options replete with controversies make it a tough predicament. A thorough understanding of the disease and treatment options is indispensable to treat such a case.

Fine needle aspiration cytology in two cases of chondromyxoid fibroma of bone and review of literature

We report the cytological features of two cases of chondromyxoid fibroma (CMF) confirmed by histopathology examination. First case was a 40-year-old male who presented with a foot swelling, and the second case was a 16-year-old male with a lesion at the angle of jaw. A fine needle aspiration cytology (FNAC) was performed in both the cases. In first case, a correct diagnosis of CMF could be offered on FNAC. In the second case, though the cytology diagnosis was a sarcoma considering the cytological, radiological and clinical features, the histopathological examination confirmed the same to be a CMF. The cases are being discussed to highlight the usefulness of FNAC to diagnose these uncommon benign bone lesions and the potential pitfalls in the cytological diagnosis of chondroid lesions.

Chondromyxoid fibroma of the zygoma: a case report

Chondromyxoid fibroma is a rare benign tumour of chondral origin. It usually involves the long bones of the lower extremity, whilst involvement of craniofacial skeleton is extremely unusual. The second case of chondromyxoid fibroma of the zygoma described in literature is presented and the surgical resection of the lesion with tumour-free margins as the key factor for avoiding local recurrence of this tumour is emphasised.
