Chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses

[Retrofacial approach to remove a rare chondromyxoid fibroma of the infralabyrinthine space]

A very rare case of 46-yaer-old woman with chondromyxoid fibroma (CMF) of infralabyrinthine area of temporal bone was described in this article. The only manifestation of this disease was a severe temporary pain in the postauricular area with irradiation in the occipital bone and headache during the last 3 months. A detail description of the CT scan and MRI data was presented. Tumor removing was performed through the retrofacial approach with combination of the microscopic and endoscopic assistance technique, which allows to had a good visualization and controlling of tumor separation from the vital structures with hearing and facial nerve function preserve. Also, we presented a brief review of literature with differential diagnosis of the CMF of the temporal bone, which conducted to minimize the diagnosis mismatches in the otologic and head and neck practice and to optimize the treatment of patients with such tumor.

Sinonasal Chondromyxoid Fibroma: Case Report and Literature Review

Chondromyxoid fibroma (CMF) is a rare, benign neoplasm of the chondroid, myxoid, and fibrous tissue. It characteristically affects the lower extremity long bones, although it may rarely arise within the craniofacial skeleton. We report the diagnosis and management of a 31-year-old male with a large, incidentally discovered CMF originating from the sphenoid sinus. A subsequent review of the literature reveals the need to differentiate from more aggressive neoplasms, such as chondrosarcoma and chondroma, which share radiographic features. A histopathologic examination is crucial for proper diagnosis and treatment. We discuss clinical sequelae, highlight the importance of a thorough pre-operative evaluation, and summarize previously suggested treatment paradigms.

Chondromyxoid fibroma of the nasal septum: case report and review of literature

BACKGROUND

Chondromyxoid fibroma (CMF) is a rare bone tumor, accounting for less than 0.5% of all bone tumors, with a predilection for lower extremity bone metaphyses. Involvement of the head and neck is extremely rare, with only 3 cases reported in the nasal septum in world literature.

METHODS

This is a case report of a CMF in the nasal septum of a 49-year-old woman with a 6-month history of congestion. MRI showed a bilobed mass originating from the nasal septum. Histologic and immunoperoxidase staining as well as electron microscopic studies were performed. A literature review was performed.

RESULTS

The patient underwent a midface-degloving approach for surgical resection. The final pathology was prototypic of CMF. The patient was disease-free 16 months postoperatively.

CONCLUSIONS

CMF is a rare, benign neoplasm occasionally occurring in the head and neck. Surgical resection is often curative. CMF must be differentiated from chondrosarcoma, given the substantial differences in treatment.

Chondromyxoid fibroma of the skull base: differential diagnosis and radiotherapy: two case reports and a review of the literature

Chondromyxoid fibromas are uncommon tumours mostly arising in long bones of young males. Involvement of the skull base is extremely rare. We describe two new cases of base of the skull chondromyxoid fibromas. The tumours were incompletely excised and irradiated with protons because of the high risk of complications of another surgical procedure. The rationale for proton therapy was based on the intimate relations between the tumour and the organs at risk. Skull base chondromyxoid fibroma is a very rare, slowly growing benign tumour that can cause severe disabilities due to tumour compression of critical structures. Only surgical resection has been shown to be relatively effective. We report two cases of incompletely excised lesions treated by postoperative high-dose radiation including proton therapy with no active disease and complication. Our review of the literature allows us to conclude that histological diagnosis of lesions in this site is a trap for pathologists and that radiotherapy is not contraindicated.

Orbital Invasion by Chondromyxoid Fibroma of the Ethmoid Sinus

A 10-year-old girl presented with painless progressive proptosis of the left eye. CT and MRI of the orbits showed a large ethmoidal mass invading the orbit. Clinically, despite its size, the tumor was not inducing any functional signs. A coronal approach was used to remove the tumor en bloc. Histopathology revealed that the lesion was a chondromyxoid fibroma, a neoplasm unreported in the ophthalmic literature.

Chondromyxoid fibroma of the parietal bone

We report the case of an 11-year old girl who presented with an intracranial chondromyxoid fibroma arising from parietal bone. Chondromyxoid fibroma is a benign cartilaginous neoplasm, which can be easily mistaken for chondrosarcoma, especially in small biopsies. It is more common in long bones and is least common in cranial bones. Published work describes about 33 cases occurring in cranial bones with almost equal incidence in the bones of the base of the skull and cranial vault. To our knowledge, this is the second case of chondromyxoid fibroma reported to occur in parietal bone and is the first case reported in an English-language journal. We present this case for its rare anatomical, clinical, radiological and histological presentations.

Chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses: report of one case and a review of the literature

Chondromyxoid fibroma is a rare benign tumor that usually occurs in the long bones. A 50-year-old patient presented with chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses. This is the fourth case reported to date in the literature. The clinical manifestations of the tumor were very limited, and the appearance at rhinoscopy was misleading. Radiologic imaging showed a soft tissue lesion invading the adjacent bony structures and the dura mater. Surgery was performed by a combined team of otorhinolaryngologists and neurosurgeons, and total excision of the tumor was achieved. The histologic diagnosis of this tumor is difficult because of its similarities to chondrosarcoma. [Editorial comment: The authors concisely review management of this rare tumor, emphasizing that complete surgical excision, rather than curettage, is required for long term control.]

Chondromyxoid fibroma of the nasal septum: a case report emphasizing clinical correlation

Chondromyxoid fibromas are uncommon tumors most often seen in long bones of adolescent and young males. Involvement of craniofacial bones is extremely unusual, with sporadic case reports described in the literature. We describe the first case of chondromyxoid fibroma arising in the nasal septum with local destruction and expansile growth into the ethmoid bone and inferior turbinate in a 60-year-old female. The fortuitous discovery of this otherwise asymptomatic lesion and its follow-up are detailed. The literature is reviewed and salient clinical, radiographic, and pathologic correlative findings are emphasized.
