Soft tissue recurrence of chondromyxoid fibroma

Chondromyxoid Fibroma of the Distal Tibia: A Rare Case Report

Chondromyxoid fibroma is one of the rarest bone tumours, occurring most frequently in adult men in their second and third decades. It generally affects the metaphysis of long bones, particularly the femur and tibia. Diagnosis can pose differential challenges with various tumor types, particularly chondrosarcoma, requiring separate management. We present a case of chondromyxoid fibroma of the distal tibia detected by soft tissue swelling. Clinical, epidemiological and radiological aspects will be discussed.

Diagnosis and Literature Review of Chondromyxoid Fibroma - A Pathological Puzzle

INTRODUCTION

Chondromyxoid fibroma (CMF) is a benign rare bone tumor of slow-growing nature arising from chondroblastic derivation. CMF in most of the cases is a diagnosis of exclusion, and in this case report, we differentiate the histological and radiological findings of CMF and difficulties in diagnosis of CMF from potential differential diagnosis.

CASE REPORT

A 38-year-old female patient presented with a history of limping for 5 months and on evaluation revealed an expansile osteolytic lesion in fibular head with septations and soft tissue component. Excision biopsy was done. Histological examination revealed a cellular neoplasm arranged as vague nodules in chondroid background with occasional mitotic figures and giant cells in periphery without any calcification. To rule out chondroblastoma, S-100 and epithelial markers were done which was negative establishing diagnosis of CMF by exclusion.

CONCLUSION

CMF is often misdiagnosed being a radiological and pathological mimicker. Histology remains key to diagnosis. En bloc resection remains the mainstay of management in expendable bone-like fibula.

Chondromyxoid fibroma involving the entire metacarpal: a case report

The occurrence of chondromyxoid fibroma in the hand is rare. We report a case of chondromyxoid fibroma involving the whole fourth metacarpal that was treated by curettage and cancellous bone allograft.

Chondromyxoid fibroma of the upper thoracic spine in a 7-year-old patient. A case report and review of the literature

BACKGROUND

We report a case of a 7-year-old white female who presented with acute, progressive bilateral lower extremity weakness over 48 h.

METHODS

Case report and presentation of clinical, radiological and pathological data on a single case of chondromyxoid fibroma (CMF) of the T2 vertebral body.

RESULTS

Magnetic resonance imaging of the thoracic spine revealed an extensive mass invading the lamina of the second thoracic vertebra, causing extensive cord compression and progressive neurological deterioration. Surgical resection and pathologic study of the mass revealed a CMF.

CONCLUSIONS

A thorough Medline search has revealed that only 25 cases of spinal CMF have been reported, making this lesion an extremely rare bone tumor.

Recurrent chondromyxoid fibroma of the thoracic spine 30 years after primary excision: case report and review of the literature

We report a case of late recurrence of chondromyxoid fibroma (CMF) arising in a thoracic vertebra in an 11-year-old male. This was treated by curettage, and 30 years later, the patient noticed shoulder pain and leg weakness. A recurrent mass appeared at the same site in the spinous process of T6. The histologic features of the recurrent tumor were similar to those of the primary lesion. A total of 38 cases of CMF of the vertebra have been reported. Only 3 of 38 previously reported vertebral CMF recurred. Tumors recurred 2 years after operation in 2 cases, and 7 years after operation in 1 case.

Chondromyxoid fibroma of bone: a clinicopathologic review of 278 cases

In a study of the clinical, radiographic, and pathological features of chondromyxoid fibroma, the tumor was slightly more common in men, usually in the second decade of life. Almost half of the tumors involved the long bones, although the ilium and the small bones were also common sites. Roentgenograms showed a sharply marginated, lobulated, lucent defect in the metaphysis. The tumor involved the medullary bone in an eccentric fashion, and the cortex was thinned and expanded. Periosteal reaction and soft tissue extension were uncommon. Mineralization was identified in 13% of the lesions. Histologically, the tumors were almost always arranged in lobules, which were prominent (macrolobular) or somewhat indistinct (microlobular). The tumor cells were spindle-shaped or stellate and arranged in a myxoid matrix. Calcification was seen in more than one third of the cases but was rarely prominent. Hyaline cartilage and chondroblastoma-like areas were not uncommon. Approximately 18% of tumors showed bizarre nuclei. Permeation of bony trabeculae was uncommon. Treatment was conservative surgical removal; approximately one fourth of the patients had recurrence.

Chondromyxoid fibroma of the ala of the sacrum presenting as a cause of lumbar pain in an adolescent

We report a case of chondromyxoid fibroma of the ala of the sacrum: its presentation, diagnosis, treatment, and resolution. Although this tumor is admittedly rare, our case demonstrates the need for careful evaluation of pack pain in an adolescent.

Chondromyxoid fibroma of the foot bones

A rare tumor affecting bones of the lower extremity is discussed. A thorough literature review describes a limited number of cases, reported by different authors. Radiographic and microscopic identification of this pathology, as well as definitive treatment, is suggested.

Case report 798: Recurrent chondromyxoid fibroma in connective tissue of leg

In summary, this is a case of recurrent CMF in soft tissue, 17 years after the diagnosis of the initial lesion. The literature concerning this entity is reviewed and the histological and radiological patterns are considered. The causative factors are evaluated and the prognosis is discussed.

Quiz: case report 776. Chondromyxoid fibroma of femur

CMF is a rare neoplasm of bone, comprising less than 1% of primary bone tumors. The neoplasm was first described in 1948 by Jaffe and Lichtenstein as a separate entity from chondrosarcomas, having slightly different plain film characteristics and a benign clinical course. As of 1985, Kreicbergs, Lonnquist, and Willems estimated that approximately 400 cases have been published. Recently, we encountered a CMF with an unusual clinical presentation. The efficacy of MRI studies is shown.
