Connective and soft tissue neoplasms

Mesothelioma is a type of cancer that develops from the thin layer of tissue that covers many of the internal organs (known as the mesothelium). The area most commonly affected is the lining of the lungs and chest wall. Less commonly the lining of the abdomen and rarely the sac surrounding the heart, or the sac surrounding each testis may be affected. Signs and symptoms of mesothelioma may include shortness of breath due to fluid around the lung, a swollen abdomen, chest wall pain, cough, feeling tired, and weight loss. These symptoms typically come on slowly.

Rhabdomyosarcoma (RMS) is a highly aggressive form of cancer that develops from mesenchymal cells that have failed to fully differentiate into myocytes of skeletal muscle. Cells of the tumor are identified as rhabdomyoblasts.

A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. The word is . The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.

A myxoma (New Latin from Greek 'mucus') is a myxoid tumor of primitive connective tissue. It is most commonly found in the heart (and is the most common primary tumor of the heart in adults) but can also occur in other locations.

Fibrosarcoma (fibroblastic sarcoma) is a malignant mesenchymal tumour derived from fibrous connective tissue and characterized by the presence of immature proliferating fibroblasts or undifferentiated anaplastic spindle cells in a storiform pattern. Fibrosarcomas mainly arise in people between the ages of 25 and 79, but may also occur in infants. It originates in fibrous tissues of the bone and invades long or flat bones such as the femur, tibia, and mandible. It also involves the periosteum and overlying muscle.

medical condition

Lymphangiosarcoma is a rare cancer which occurs in long-standing cases of primary or secondary lymphedema (swelling due to lymphatic system obstruction). It involves either the upper or lower lymphedematous extremities but is most common in upper extremities. Although its name implies lymphatic origin, it is believed to arise from endothelial cells and may be more accurately referred to as angiosarcoma.

Angiofibroma (AGF) is a descriptive term for a wide range of benign skin or mucous membrane (i.e. the outer membrane lining body cavities such as the mouth and nose) lesions in which individuals have: benign papules, i.e. pinhead-sized elevations that lack visible evidence of containing fluid; nodules, i.e. small firm lumps usually > 1 mm in diameter; and/or tumors, i.e. masses often regarded as ~8 mm or larger.

Myelolipoma (, from the Ancient Greek 'marrow'; , 'of, or pertaining to, fat'; -oma 'tumor or mass'; also myolipoma) is a benign tumor-like lesion composed of mature adipose (fat) tissue and haematopoietic (blood-forming) elements in various proportions.
