Actinomycosis is a rare anaerobic, gram-positive bacterial infection caused by Actinomyces. As an site for the disease, cervicofacial area common but nasal cavity and nasopharynx are rare. causes chronic purulent granulomatous characterized extensive infiltration, necrosis, bone destruction on CT. Extranodal natural killer/T cell (NK/T cell) lymphoma, type more in East Asia than elsewhere, comp...

Extranodal natural killer cell (NK) T lymphoma (ENKL) is a rare type of non Hodgkins lymphoma, accounting for 5% 10% total NHL cases.

PRACTICAL RELEVANCE The majority of feline lymphoma is extranodal. While the gastrointestinal (GI) tract is the most commonly affected site, non-GI extranodal lymphomas, which are the focus of this review, account for a large proportion of lymphomas in cats. This article discusses prognostic factors for the most common of these extranodal lymphomas, both in general terms and specifically for in...

peripheral t-cell lymphomas are a group of heterogeneous disorders and according to who classification, are categorized into nodal and extranodal forms. nk/t-cell lymphoma, nasal type, is a subtype of extranodal peripheral t-cell lymphoma and commonly presents as a midfacial destructive lesion. this disorder is more prevalent in asia and south america and has a strong association with epstein b...

Mantle cell lymphoma is an aggressive type of B-cell non-Hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. The gastrointestinal tract is the predominant site of extranodal involvement in the form of multiple lymphomatous polyposis. Multiple lymphomatous polyposis due to mantle cell lymphoma presenting with intussusception is ...

Peripheral T-cell lymphomas are a group of heterogeneous disorders and according to WHO classification, are categorized into nodal and extranodal forms. NK/T-cell lymphoma, nasal type, is a subtype of extranodal peripheral T-cell lymphoma and commonly presents as a midfacial destructive lesion.

Primary pancreatic lymphoma is a rare extranodal manifestation of any histopathologic subtype of B cell non-Hodgkin's lymphoma that predominantly involves the pancreas. It comprises less than 0.2% of pancreatic malignancies and less than 0.7% of non-Hodgkin's lymphomas. This lymphoma is almost never suspected clinically. It is usually diagnosed by surgical exploration for suspected adenoca...

OBJECTIVE The purpose of this article is to illustrate the spectrum of appearances of extranodal lymphoma in the abdomen using cross-sectional imaging techniques. CONCLUSION Extranodal lymphoma in the abdomen can mimic other neoplastic or inflammatory conditions. Although a definitive diagnosis is possible only with biopsy, it is important to consider extranodal lymphoma in the presence of ce...

CT findings were reviewed in 68 patients with untreated head and neck lymphoma. More than half of the patients with either Hodgkin's disease or non-Hodgkin's lymphoma were detected in the earlier stages (stage I or II). Four types of abnormalities were identified with CT: nodal involvement alone (type 1), extranodal involvement alone (type 2), a combination of extranodal and nodal disease (type...
