Overview

Chondromyxoid fibroma is a rare benign bone tumor accounting for approximately 1% of all benign bone tumors. Chondromyxoid fibroma affects all age groups. It is more commonly seen during the second and third decades of life. Men are more commonly affected than women. Chondromyxoid fibroma arising from the physeal remnant is the commonly proposed theory in the pathogenesis of this tumor. It is predominantly found in the metaphyses of the long bones. The bones involved include tibia, distal femur, pelvis, feet and hands. Chromosome 6 appears to be involved in chondromyxoid fibroma. Over expression of the glutamate receptor gene GRM1 in patients with chondromyxoid fibroma via promoter swapping and gene fusion has been observed. The hallmark of chondromyxoid fibroma is pain, swelling, and pathological fracture. The mainstay of treatment for chondromyxoid fibroma is surgery (curettage and bone grafting).

Historical Perspective

In 1948, Jaffe and Lichtenstein described chondromyxoid fibroma for the first time.^[1]

Classification

Chondromyxoid fibroma can be classified based on imaging findings.

Enneking (MSTS) Staging System

The Enneking surgical staging system (also known as the MSTS system) for benign musculoskeletal tumors is based on radiographic characteristics of the tumor host margin.^[2]
It is widely accepted and routinely used classification.

Stages	Description

1	Latent: Well demarcated borders
2	Active: Indistinct borders
3	Aggressive: Indistinct borders

Pathophysiology

The exact etiology of chondromyxoid fibroma is unknown.^[3]
Chondromyxoid fibroma arising from the physeal remnant is the commonly proposed theory in the pathogenesis of chondromyxoid fibroma.^[4]
It is predominantly found in the metaphyses of the long bones.^[5]
The bones involved by chondromyxoid fibroma includes tibia, distal femur, pelvis, feet and hands.^[6]

Genetics

Chromosome 6 appears to be involved in chondromyxoid fibroma.^[5]^[7]
The non-random clonal abnormalities involves 6p25, 6q13 and 6q23.^[5]
Whole-genome mate-pair sequencing and RNA sequencing showed over expression of the glutamate receptor gene GRM1 in patients with chondromyxoid fibroma via promoter swapping and gene fusion.^[8]

Causes

There are no established causes of chondromyxoid fibroma.^[9]

Differentiating Chondromyxoid Fibroma from Other Diseases

Chondromyxoid fibroma must be differentiated from the following bone disorders:^[10]

Disease	Bubbly lytic lesion on x-ray	Lakes of Blood on histology	Diagnosis	Treatment is curretage and bone grafting
Chondromyxoid Fibroma	-	-	Radiology and biopsy	+
Unicameral bone cyst	+	-	Radiology and biopsy	-
Non ossifying fibroma	+	-	Radiology and biopsy	-
Giant cell tumor	-	-	Radiology and Biopsy	+
Chondroblastoma	-	-	Biopsy	+
Aneurysmal bone cyst	+	+	Radiology and biopsy	+
Osteoblastoma	-	-	Radiology and biopsy	+
Telangiectatic osteosarcoma	-	+	Radiology and biopsy	-

Epidemiology and Demographics

Chondromyxoid fibroma is a rare benign bone tumor accounting for approximately 1% of all benign bone tumors.^[11]
Chondromyxoid fibroma affects all age groups.
It is more commonly seen during the second and third decades of life.
Men are more commonly affected than women.
There is no racial predilection to chondromyxoid fibroma.

Risk Factors

There are no established risk factors for chondromyxoid fibroma.

Screening

There is insufficient evidence to recommend routine screening for chondromyxoid fibroma.

Natural History, Complications, and Prognosis

Common complications of chondromyxoid fibroma include:

Pathological fracture
Premature epiphyseal closure
Limb-length discrepancy
Angular deformity

Prognosis is generally good for chondromyxoid fibroma.

Prognostic variables include:
- Children
- When the Tumor is more lobulated with abundant myxoid material

Diagnostic Study of Choice

Biopsy is the diagnostic study of choice for chondromyxoid fibroma.
Biopsy findings under low and high power fields are given below:^[12]^[13]

Under Low Power field:

It has a biphasic appearance
It has lobules and pseudolobules of fibromyxoid tissue with hypercellular area.
The cells are spindle-shaped or stellate-shaped and contain hyperchromatic nuclei.
Multinucleated giant cells and fibrovascular tissue may be present between the lobules.
Hypocellular area with chondroid material is seen.

Under High Power Field:

The tumor shows myxoid stroma mixed with stellate cells.
In addition, an area of pleiomorphic cells with bizarre nuclei may be seen.

History and Symptoms

The majority of patients with chondromyxoid fibroma have a positive history of:

Physical Examination

Common physical examination findings of chondromyxoid fibroma include:

Deformity

Swelling
Decreased range of motion
Warmth over the affected area

Laboratory Findings

There are no diagnostic laboratory findings associated with chondromyxoid fibroma.

Electrocardiogram

There are no ECG findings associated with chondromyxoid fibroma.

X-ray

X-ray findings include:^[14]^[15]

The tumor appears as a lytic, eccentric metaphyse al lesion.

Size of the lesion may vary from 2 to 10 cm.
It has a sharply demarcated border from the adjacent bone.

It may show scalloped and sclerotic rim
Calcification is usually not seen
The tumor may show cortical expansion.

Echocardiography or Ultrasound

There are no echocardiography/ultrasound findings associated with chondromyxoid fibroma.

CT scan

CT scan confirms the x-ray findings.^[16]
It is superior to x-ray for analyzing the expansion of the lesion and cortical breach.

MRI

MRI findings of chondromyxoid fibroma include:^[17]^[18]

T1 image: Chondroid and myxoid tissues produce low signals.
T2 image: Chondroid and myxoid tissues produce high signals.

Other Imaging Findings

Bone Scan

Increased uptake is seen in chondromyxoid fibroma.

Other Diagnostic Studies

There are no other diagnostic studies associated with chondromyxoid fibroma.

Treatment

Medical Therapy

There is no treatment for chondromyxoid fibroma; the mainstay of therapy is surgery.

Surgery

Surgery is the mainstay of treatment for chondromyxoid fibroma.^[19]^[20]

Types

1. Intralesional Curettage

It is the mainstay of treatment for chondromyxoid fibroma.^[20]
The defect is filled with bone graft or bone cement in form of polymethlymethacrylate(PMMA).

2. En Bloc Excision

It usually reserved for recurrent cases.^[21]

Recurrence Rate

The recurrence rate is about 25% for chondromyxoid fibroma.^[22]

Primary Prevention

There are no established measures for the primary prevention of chondromyxoid fibroma.

Secondary Prevention

There are no established measures for the secondary prevention of chondromyxoid fibroma.
