Chondromyxoid Fibroma

Chondromyxoid Fibroma (Morphologic Abnormality)

It typically presents with pain, swelling, and tenderness to palpation. The lesion has a predilection for the metaphysis of long bones of the lower extremity, most commonly in the proximal tibial metaphysis. [ncbi.nlm.nih.gov]

  • Fishing

    In an effort to further define the aberrant 6q13 breakpoint and identify the molecular consequences, a fluorescence in situ hybridization (FISH)-based positional cloning strategy on chondromyxoid fibroma abnormal metaphase and interphase cells using a [ncbi.nlm.nih.gov]

  • Plethora

    However, this is very non-specific and can be found in a plethora of other bone lesions. They are benign lesions and malignant degeneration is rare. They are usually treated with curettage which however have a high recurrence rate of 25%. [en.wikipedia.org]

  • Overeating

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

    There was an over-all rate of recurrence of 27 per cent. With curettage alone there was an 80 per cent recurrence rate, but when curettage was combined with corticocancellous bone-grafting the recurrence rate decreased to 7 per cent. [moh-it.pure.elsevier.com]

  • Long Arm

    We found a novel unbalanced translocation between the long arms of chromosomes 1 and 9, resulting in loss of 1p. In addition, rearrangements involving the 6q23 and 9q22 regions were also observed. [ncbi.nlm.nih.gov]

    Using single-nucleotide polymorphism arrays, the authors first found—in tumors from two different patients—deletions in the long arm of chromosome 6, with a distal breakpoint immediately upstream of the gene that encodes metabotropic glutamate receptor [stm.sciencemag.org]

    In particular, rearrangement of the long arm of chromosome 6 at bands q13 and q25 was most frequent [ 29 – 38 ]. [doi.org]

  • Bony Swelling

    A 45-year-old female was admitted with painless bony swelling in the forehead. Computerized tomography demonstrated a well-defined expansive lesion with a sclerotic margin measuring approximately 3 cm in diameter in the right frontal bone. [ncbi.nlm.nih.gov]

    Typically people present with progressive pain, often long standing and/or bony swelling and restricted range of movement in affected limb 3,12. [en.wikipedia.org]

    swelling and restricted range of movement in affected limb 3,12. [radiopaedia.org]

    The common clinical presentation in cases of skull-bone involvement are headache with bony swelling as in our case, others include neuralgia, facial pain, exophthalmos, convulsions, and diplopia. [6] The imaging features of these lesions are characteristic [pediatricneurosciences.com]

    Patients can suffer from bony swelling, dysarthria, neuralgia, diplopia, facial pain, exophthalmos, headache, polyuria, and polydipsia. [5,6,10] In our case, the patient presented with diplopia, occasional headaches, and dizziness, which is consistent [journals.lww.com]

  • Neck Pain

    The patient has had excellent clinical and radiographic resolution of the prior instability with no neck pain, instability, or local recurrence. [ncbi.nlm.nih.gov]

    The most common clinical manifestation reported was neck pain 12-13. Radiologically CMF appears as a well-defined lytic lesion with lobulated margins, a sclerotic ring, and septations. [scielo.br]

  • Small Foot

    Chondromyxoid fibroma is a rare benign bony tumor classically occurring in the metaphyseal region of the long bones surrounding the knee, but also found with relative frequency in other long bones, the pelvis, ribs, and small foot bones. [ncbi.nlm.nih.gov]

    Classically occurring in the metaphyseal region of the long bones surrounding the knee, but also found with relative frequency in other long bones, the pelvis, ribs, and small foot bones.[2] It accounts for less than 1% of all the primary bone tumors [surgicalcasesjournal.com]

    Abstract Chondromyxoid fibroma is a rare benign bony tumor classically occurring in the metaphyseal region of the long bones surrounding the knee, but also found with relative frequency in other long bones, the pelvis, ribs, and small foot bones. [healio.com]

  • Short Arm

    Eighteen cells showed an abnormal pseudodiploid clone with a clonal translocation between the short arms of chromosomes 1 and 5 [46,XX,t(1;5)(p13;p13)] (Figure 6 ). Four of these eighteen cells had additional non-clonal single cell abnormalities. [doi.org]

  • Dizziness

    A 16-year-old Asian male presented to the hospital 12 months ago with bilateral diplopia involving right visual fields, intermittent headaches, and dizziness. [ncbi.nlm.nih.gov]

  • Intracranial Hemorrhage

    However, this case represents the first example, to our knowledge, of a chondromyxoid fibroma invading the transverse-sigmoid junction, resulting in intracranial hemorrhage. [ncbi.nlm.nih.gov]

Preoperative tumor workup was performed for our patients. We reviewed and recorded demographic data and the sign and symptoms of patients at presentation to our center. [ncbi.nlm.nih.gov]

An extensive infection workup was negative. (click for larger image) Figure 1: CT scan of the chest with three sagittal sections revealing no evidence of interstitial lung disease or air trapping. [the-rheumatologist.org]

Adequate surgical treatment needs to provide spinal stability. [ncbi.nlm.nih.gov]

This shall facilitate better treatment approaches and prognosis. This case is the first reported case of involvement of the zygomatic arch in a pediatric patient. [jomfp.in]

Prognosis The prognosis is excellent. Cytogenetics Morphological Karyotypes of 12 cases are reported in the literature. Complex cytogenic abnormalities are reported. [atlasgeneticsoncology.org]

Treatment and prognosis They are benign lesions and malignant degeneration is rare. There is a high rate of reported recurrence (up to 80%) with curettage alone, with lower rate ( 20%) with bone grafting. [radiopaedia.org]

To date, no definite etiologies have been documented. It is known that approximately 75% of the total cases of CMF affect the bones of the lower extremities. In particular, it occurs most frequently in the tibia and femur around the knee joint [3]. [surgicalcasesjournal.com]

A study by Romeo et al examined the DNA microarray of chondromyxoid fibroma and demonstrated that CMFs could be differentiated from other cartilaginous tumors. [8] Etiology As is the case with most bone tumors, no specific cause is known for CMF. [emedicine.medscape.com]

As with all rare lesions, reported epidemiology varies: age: most commonly diagnosed before 30 years of age ( 75%), mostly during second and third decades 1,12-15 full reported range from 3 to 70 years of age gender: conflicting data 2, 12,18 some series [radiopaedia.org]

Epidemiology Chondromyxoid fibroma is a very rare neoplasm accounting for less than 1% of all bone tumours, and less of 2% of all benign bone tumours. [atlasgeneticsoncology.org]

Epidemiology CMFs account for fewer than 1% of primary bone tumors in the United States. CMFs are becoming less frequently diagnosed, and thus, the current frequency is much lower than 1%. [emedicine.medscape.com]

Epidemiology demographics more common in males most common in second and third decades of life may affect patients up to 75 years old location long bones (ie. tibia, distal femur) often affects metaphyseal (proximal tibia) regions pelvis feet or hands Pathophysiology [orthobullets.com]

Pathophysiology Grossly, CMFs are firm, grayish-white masses that are sharply demarcated; they are lobulated or pseudolobulated. Their appearance can mimic that of fibrous tissue or hyaline cartilage. [emedicine.medscape.com]

A quick and accurate diagnosis of chondromyxoid fibroma can prevent unnecessary treatment that could be harmful to the patient. [ncbi.nlm.nih.gov]
