Pathological Tonsil

Rectal adenocarcinoma metastatic to the tonsil; PET-CT observations with pathological confirmation: A case report

Metastasis of rectal adenocarcinoma develops by lymphatic or hematogenous spread. The usual sites of metastasis from rectal adenocarcinoma include local and distant lymph nodes, the liver and the lungs. The current case report presents a unique case of a mass that was identified in the tonsil by positron emission tomography-computed tomography (PET-CT), indicating a metastasis from rectal adeno...

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 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...

Schwannoma of the tonsil.

Between 25 and 48% of schwannomas have been reported to occur in the head and neck region; the acoustic nerve is involved in most cases. Schwannomas arising in the tonsil are extremely uncommon. We report a case of tonsillar schwannoma in a 23-year-old woman. We also review the literature on this rare entity.
