What is Extraskeletal myxoid chondrosarcoma?

A rare, slow-growing type of cancer that forms in soft tissues outside the bone and usually has certain changes in the NR4A3 gene that cause abnormal fusion proteins to be made. Extraskeletal myxoid chondrosarcomas usually occur in the thigh but may also occur in the knee, buttock, or chest and abdomen.

What is Extraskeletal osteosarcoma?

A rare, fast-growing type of cancer that is made up of bone and cartilage cells, and forms in soft tissue near bones. It usually occurs in the thigh, buttock, shoulder, or trunk (chest and abdomen).

What is a myxoid?

Listen to pronunciation. (MIK-soyd LIH-poh-sar-KOH-muh) A rare type of cancer that begins in fat cells. It usually occurs in the thigh, but it may also occur in the buttock, back of the abdomen, or trunk (chest and abdomen).

What is clear cell chondrosarcoma?

Clear-cell chondrosarcoma is a rare, low-grade variant of chondrosarcoma characterized by slow growth, low metastatic potential, and a predilection for local recurrence long after treatment.

What does Extraskeletal mean?

Listen to pronunciation. (EK-struh-SKEH-leh-tul) Located or occurring outside of the bone. Also called extraosseous.

What does chondrosarcoma look like?

The lytic lesion usually appears well-defined, associated with endosteal scalloping, and cortical thinning or thickening. High-grade tumours show irregular margins. Calcifications of the tumoral matrix may be punctate, flocculent, or have a ring-like pattern, they can be small, or disseminated, dense or subtle.

What is the most common site for Extraskeletal osteosarcoma?

The most common location for primary extraskeletal osteosarcoma is the soft tissues of the thigh (46%), followed by the upper extremity (20%) and the retroperitoneum (17%), but can occur in any part of the body [8].

What is myxoid appearance?

A myxoid tumor is a connective tissue tumor with a “myxoid” background, composed of clear, mucoid substance.

Where is the myxoid?

Myxoid liposarcomas and extraskeletal myxoid chondrosarcomas are typically located within the lower extremities hips, buttocks and trunk 2,6. Myxoinflammatory fibroblastic sarcoma and acral fibromyxoma typically involve the distal extremities and the subcutaneous tissues 2.

What is conventional chondrosarcoma?

Conventional chondrosarcomas are the most common subtype of malignant cartilage-forming tumors, comprising an estimated 75–85% of tumors. Less common subtypes include clear cell chondrosarcoma, dedifferentiated chondrosarcoma and mesenchymal chondrosarcoma.

What is mesenchymal chondrosarcoma?

Mesenchymal chondrosarcoma is an extremely rare, often aggressive form of cancer. It is an uncommon type of chondrosarcoma. Conventional chondrosarcoma is a form of bone cancer that arises from cartilage cells. Cartilage is the specialized tissue that serves as a buffer or cushion at joints.

What are the size of chondrosarcoma?

Chondrosarcomas are large tumors, usually greater than 4 cm in size [5]. They have a translucent lobular, blue-grey, or white cut surface corresponding to the presence of hyaline cartilage.

What is Extraskeletal Ewing sarcoma?

Extraskeletal Ewing sarcoma (EES) is a rare entity that belongs to the ES family of tumors (ESFT), which is a group of small round tumor cells that share a common neural histology and genetic mechanism (1–4).

What is myxoid background?

What is a myxoid sarcoma?

A myxoid sarcoma cancer is a type of liposarcoma, a fatty tumor that develops in deep soft tissue. The condition ranges from an intermediate to high-grade tumor and typically does not manifest any symptoms until the tumor has grown and presses on surrounding tissue.

What is a grade 1 chondrosarcoma?

Grade I chondrosarcoma (syn.: atypical cartilaginous tumor) is classified as an intermediately and locally aggressive neoplasm and typically is treated less aggressively (i.e., by intralesional curettage).

What are the different types of chondrosarcoma?

Different types of chondrosarcoma have been described, as follows:

• Conventional chondrosarcoma, which accounts for nearly 90% of all chondrosarcomas.
• Dedifferentiated chondrosarcoma.
• Clear cell chondrosarcoma.
• Mesenchymal chondrosarcoma.
• Juxtacortical chondrosarcoma.
• Secondary chondrosarcoma.

How fast does chondrosarcoma grow?

Chondrosarcoma tends to grow slowly, so it might not cause signs and symptoms at first. When they occur, signs and symptoms of chondrosarcoma may include: Increasing pain. A growing lump or area of swelling.

What is extraskeletal myxoid chondrosarcoma?

Extraskeletal myxoid chondrosarcoma (EMC) is a malignant mesenchymal neoplasm of uncertain differentiation with abundant myxoid matrix, multilobular architecture, uniform cells arranged in cords, clusters and reticular networks and NR4A3 rearrangement

What is the best treatment for myxoid chondrosarcoma (myxoid cancer)?

Wide surgical removal is the best treatment. Extraskeletal myxoid chondrosarcoma is an intermediate-grade neoplasm with a tendency toward recurrence and metastasis. This rare variant of chondrosarcoma occurs in the deep soft tissues, usually of the limb girdles or extremities, but may occur in the trunk wall, thorax, abdomen, breast, or elsewhere.

What are the histologic findings characteristic of a myxoid stroma tumor?

Comment: The tumor has a multinodular architecture. Thick fibrous bands separate pools of myxoid stroma containing uniform tumor cells with eosinophilic or vacuolated cytoplasm and round to oval nuclei with evenly distributed chromatin and inconspicuous nucleolus. The cells are interconnected with one another to form cords and small clusters.

Where does chondrosarcoma affect the body?

This rare variant of chondrosarcoma occurs in the deep soft tissues, usually of the limb girdles or extremities, but may occur in the trunk wall, thorax, abdomen, breast, or elsewhere. An identical tumor also arises in bone.
