Desmoplastic Mesothelioma Prognosis

In one seven year study 1982 1989 that evaluated 255 cases of mesothelioma researchers identified 17 cases of desmoplastic mesothelioma. These cells are found in around 20 of pleural mesothelioma diagnoses and 4 or 5 of peritoneal mesothelioma diagnoses.

Sarcomatoid Mesothelioma Get Diagnosed Treated

Desmoplastic malignant mesothelioma is a rare subtype of diffuse malignant mesothelioma defined as a sarcomatoid mesothelioma that has greater than 50 dense collagenized stroma sometimes with a vague storiform appearancewhat that means is that the molecular structure of the cell includes elements not found in a typical sarcomatoid mesothelioma cell.

Desmoplastic mesothelioma prognosis. Its pathological characteristics include dense collagen fibers in a storiform pattern. Because mesothelioma is generally difficult to diagnose this sub type in particular it usually isnt discovered until the cancer is in the later stages. This website is intended for pathologists and laboratory personnel who understand that medical information is imperfect and must be interpreted using reasonable medical judgment.

Desmoplastic mesothelioma is categorized as a sarcomatoid cancer which is typified by a poor prognosis. Desmoplastic malignant pleural mesothelioma dmm is rare histological subtype of diffuse malignant pleural mesothelioma mpm accounting for 5 10 of cases. Desmoplastic malignant mesothelioma dmm is a rare histological subtype of sarcomatoid malignant mesothelioma arising most frequently in the pleura or peritoneum and less frequently in the lung parenchyma.

The tumors associated with desmoplastic mesothelioma are usually more than 50 fibrous with a bland hard to recognize pattern. The prognosis for desmoplastic mesothelioma is not usually positive. In this case the life expectancy following diagnosis is usually less than one year.

At this point it is virtually impossible to cure and life expectancy is short. Desmoplastic mesothelioma desmoplastic mesothelioma is a subtype of malignant mesothelioma an incurable cancer typically affecting the tissues that line the lungs heart or abdomen. A 52 year old female with no apparent asbestos exposure was referred for consultation in our center after 1 month of cough and no concomitant symptoms of chest.

Desmoplastic mesothelioma a cell subtype of malignant mesothelioma is a variant of another cell type known as sarcomatoidalthough research is still ongoing in order to find favorable treatment options for this subtype the prognosis is currently grim. It is hard to diagnose this cancer because it is so similar to healthy tissue. Pleura mesothelioma desmoplastic.

This type of mesothelioma which is a subset of the sarcomatoid mesothelioma cell type involves a patternless makeup of dense tissue fibers called collagen the lack of structure to the tissue makes desmoplastic mesothelioma challenging to identify from scans and biopsies. In many cases this type of mesothelioma will be misdiagnosed as other conditions such as fibrous pleurisy or even renal cell carcinoma. It has a poor prognosis with direct invasion of the chest wall or lungs and distant metastases.
