Lymphosarcoma of Tonsil

Uveal lymphosarcoma.

LYMPHOMATOUS tumours involving the lids and orbit have been recognized and repeatedly reported in the literature for many years; intra-ocular involvement on the contrary is rare if the lymphomatous infiltrations associated with lymphatic leukaemia are excluded. Kukain (1935) and Triebenstein (1920) have each described a case of uveal lymphosarcoma complicated by secondary glaucoma, and other is...

Tonsil fibromatosis.

Fibromatosis is a non-metastatic, however locally invasive tumor that may infiltrate muscle, fat, and bone. It may be fatal depending on its location. Tumors in the head and neck are particularly dangerous. These fibroblast tumors have poorly defined margins and are not encapsulated. Anaplasia and invasion of nerves and vessels are not present; mitosis is rare and there may be collagen between ...

Primary lymphosarcoma of the lung.

Transplantation of Lymphosarcoma in Calves1

Bovine lymphosarcoma cells were transplanted into six new born calves which had first received 200 rads of whole-body irradiation. Distinct subcutaneous masses, involving one or more prefemoral and/or prescapular lymph nodes, were evident within one or two weeks after inoculation of lymphosarcoma cell suspensions. In each instance, it was ]x>ssible to make a histologie diagnosis of lymphosarcom...

Primary adenomyoepithelioma of tonsil

We present a case of adenomyoepithlioma (AME) arising from the tonsil. AME is an uncommon tumor that typically arises in breast, but rarely found in salivary glands, lung, and skin. Its biological features have not been thoroughly characterized. Here we describe a primary AME originating from the tonsil. The pathologic changes were characterized by hypercellularity, the dominance of both epithe...
