Chondromyxoid fibroma of the ethmoid sinus

A Case Report of Chondromyxoid Fibroma of the Nasal Cavity

The chondromyxoid fibroma is a benign osseocartilaginous tumor histopathologically characterized by chondroid, fibrous, and myxoid tissues (Nazeer et al. in Skeltal Radiol 25:779-78, 1996). Its occurrence is quite rare, accounting for less than 0.5% of all bone tumors, with 1-5% of cases reported in the head and neck region. We report an unusual case of 25 years old male who presented with progressive swelling over dorsum of nose with bilateral nasal obstruction over 1 year. The histopathological examination was suggestive of chondromyxoid fibroma. The tumor was completely excised via open approach. We report this case owing to the rarity of the disease, sometimes masquerading as invasive/malignant pathology.

Rapidly expanding chondromyxoid fibroma of the mandible: A case report of rare entity

Chondromyxoid fibroma is an unusual, benign bone tumour that is usually sited in the metaphyseal region of the long bones. It accounts for less than 1% of all bone tumours. It manifests predominantly in males in their second and third decades of life. Rarely, it occurs in the bones of the craniofacial skeleton. For small, lesions enucleation and curettage and for larger lesions, resection followed by are the treatment modalities available. Here, we present a case of chondromyxoid fibroma with respect to the right side of the mandible which was managed by surgical resection followed by reconstruction under general anaesthesia. Resection followed by reconstruction provides satisfactory outcomes, especially in cases with large lesions. Chondromyxoid fibroma is an asymptomatic, benign, slow-growing lesion but can rapidly expand and involve the greater area of bone. Thus, its detection at an early stage and treatment at the proper time can lead to less morbidity associated with the lesion and improved quality of life of the patient.

Primary Orbital Chondromyxoid Fibroma: A Cause of Monosymptomatic Periocular Pain

Chondromyxoid fibroma (CMF) is a very rare entity, accounting for <1% of all bone tumours. So far, only 4 cases have been reported with the orbit as primary location. Here, we present a case of orbital CMF with periocular pain as the presenting symptom and as the only symptom when the tumour recurred after surgery. A 41-year-old man underwent a CT scan and later an MRI as part of evaluation for left periocular pain that had persisted for a year. Clinical examination was normal. CT and MRI revealed an irregular mass in the lateral part of the left orbital roof. The tumour was removed by curettage, and histopathological examination showed a CMF. The pain was absent for 3 months. A second MRI 5 months postoperatively revealed a recurrence, which was removed surgically, resulting in pain alleviation. In conclusion, CMF is a potential cause of periocular pain, and persistent periocular pain with normal clinical findings should warrant a CT or MRI scan.

Chondromyxoid fibroma of the temporal bone: A rare case report

RATIONALE

Chondromyxoid fibroma (CMF) is a rare form of benign bone tumor and easily misdiagnosed as fibrosarcoma. Hence, to explore the clinical manifestations, diagnostic tests, and therapeutic procedures for temporal bone cartilage myxoid fibroma, it is important to optimize patient treatment and avoid overtreatment. Previous research has discussed cases of CMF, but this paper presents a systematic, complete, and comprehensive introduction of this disease based on this case and related literature.

PATIENT CONCERNS

A 52-year-old male patient presented with pain in his right ear for 2 years and hearing loss in his right ear with tinnitus for 1 year. The patient had a history of hypertension for 9 years and it was well-controlled.

DIAGNOSIS

A computed tomography (CT) scan of the temporal bone showed an expansive growth on the right temporal bone plate and tympanic plate, presenting as a cloud-like ground glass opaque shadow involving the temporom and ibular joint, middle skull base, and small auditory bones. A magnetic resonance imaging (MRI) of the temporal bone showed a large and irregular soft tissue mass shadow on the right temporal bone plate. The right temporal bone plate was occupied by the lesion, consistent with a bone origin. From the results of the imaging examination of the patient, a lesion occupying the temporal bone in the right ear and mastoiditis in the right middle ear was initially diagnosed.

INTERVENTIONS

Right ear temporal bone tumor resection and abdominal fat extraction were conducted.

OUTCOMES

Postoperative pathological results demonstrated myxoid fibroma of the temporal bone cartilage. No recurrence or severe complications were observed in 8 months of follow-up.

LESSONS

A finding of myxoid fibroma of the temporal bone cartilage is rare in the clinic. The growth of such tumors is slow. The temporal bone CT and inner ear MRI were helpful in diagnosis. Surgery was the principal treatment.

Soft Tissue Special Issue: Chondroid Neoplasms of the Skull

Clinically, radiologically, and pathologically, chondroid neoplasms of the skull can be diagnostically challenging due to overlapping features in each of these domains. Compounding the problem for the pathologist, there is also significant morphologic, immunophenotypic, and molecular genetic overlap between benign and malignant cartilaginous lesions, and the majority of these lesions are encountered quite rarely in routine surgical pathology practice. Each of these factors contribute to the diagnostic difficulty posed by these lesions, highlighting the importance of radiologic-pathologic correlation in the diagnosis. This review is intended to provide an update for surgical pathologists on some of the most commonly encountered chondroid neoplasms in the skull, and includes the following lesions: chondromyxoid fibroma, synovial chondromatosis, chondrosarcoma and variants, and chordoma and variants. For each of these lesions, the differential diagnosis and useful ancillary tests will be discussed in the context of a broad range of additional primary and secondary lesions.

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 Radius: A Case Report

Chondromyxoid fibroma (CMF) is a rare benign cartilaginous tumour accounting to less than 1% of bone tumours. It is most commonly seen in lower extremity involving tibia. CMF of radius is rare. We report a rare case of CMF of proximal radius in a 37-year-old female who presented with swelling and pain over right elbow. Wide local excision of proximal radius along with radial head was done and above elbow POP slab was applied for one month. Elbow range of movement exercises started after one month.

Chondromyxoid fibroma of the mandible: Case report and review of the literature

INTRODUCTION

Chondromyxofibroma (CMF) is exceedingly rare, accounting for 0.5% of the 10,065 bone tumors categorized by Unni and Inwards and 1.6% of their catalog of benign bone tumors. Only 2 of the 50 chondromyxoid fibromas included in their study occurred in the skull. Chondromyxoid fibroma of the maxillofacial region is typically seen in patients in the 2nd-3rd decade of life with slight female predominance. It is more commonly seen in the maxilla and is unusual in the sphenoid and ethmoid sinuses. The tumor is composed of hypocellular chondroid or myxochondroid tissue with multinucleated giant cells.

CASE REPORT

A 30 year old Nigerian house wife was seen at the Oral and Maxillofacial clinic of the Dental and Maxillofacial Department of the Federal Medical Centre Lokoja with a 4 year history of Rt mandibular swelling which was initially slow growing and painless and difficulty in eating. The whole lesion was removed and result confirmed the previous biopsy of chondromyxofbroma of the jaw.

CONCLUSION

Patients with CMF need close monitoring due to high rate of recurrence with cases of malignant transformation at rate of 1-2%, and this seems to have occurred following irradiation.
