lymphomatous

Lymphomatous involvement of the oesophageal wall is rare.

This is done through histological demonstration of lymphomatous infiltration into the affected tissue.

Additionally, it may be considered a precursor or variant of the lymphomatous skin disorder mycosis fungoides, which is also associated with large plaque parapsoriasis.

Mantle cell lymphoma is found in lymph nodes, the spleen, bone marrow, blood, and sometimes the gastrointestinal system (lymphomatous polyposis).

Besides lesions in the peripheral nerves, there are frequently lymphomatous infiltration/tumours in the skin, skeletal muscle, visceral organs.

Since mantle cell lymphoma may present a lymphomatous polyposis coli and colon involvement is common, colonoscopy is now considered a routine part of the evaluation.

The subsequent biopsy of a lymphomatous pleural plaque, visible on previous radiographs, permitted the retrospective deduction of lymphoma at initial presentaton.

Mauri C, Paterlini P : Histological and immunohistochemical characterization of lymphomatous extranodal localizations.

The definition of PTLD is frequently limited to lymphomatous lesions (low-stage or high-stage), which are often extranodal (frequently in the allograft).

A case of enteropathy associated T cell lymphoma (EATCL) is described, which was diagnosed by biopsy of a lymphomatous pleural mass.

The lymphomatous infiltrates need to be differentiated from other conditions that affect poultry including Lymphoid Leukosis and Reticuloendotheliosis, as well as an inflammatory event associated with hyperplastic changes of the affected tissue.

Marshak was the first to introduce the term "endoexoenteric" to refer to a specific radiographic pattern (seen on x-rays, CT scans or PET scans) of lymphomatous involvement of the bowel.

It has been argued, however, that in some cases of adult onset 'coeliac' disease the histological findings of villous atrophy, crypt hyperplasia, and intra-epithelial lymphocytosis may be a response to low grade lymphomatous infiltration.

This terminology derives from the fact that in this form of lymphomatous invasion of the bowel, the tumor extends throughout the entire width of the bowel wall, from the luminal or mucosal (endo) surface to the serosal (exo) surface.

For example, soft tissue sarcomas and lymphomatous masses show a reduction in signal on T2 weighted images in response to treatment, and bone tumours may show a mixed response with persistent areas of low signal remaining and areas of high signal developing within the bone marrow.
