Clinical and histopathological evaluation of 16 dogs with T-zone lymphoma
Clinical and histopathological characteristics of 16 dogs with nodal paracortical (T-zone) lymphoma (TZL) were evaluated. At initial examination, generalized lymphadenopathy was found in all dogs, and peripheral lymphocytosis was found in 10 of the 16 dogs. At initial diagnosis or during the disease...

description | Clinical and histopathological characteristics of 16 dogs with nodal paracortical (T-zone) lymphoma (TZL) were evaluated. At initial examination, generalized lymphadenopathy was found in all dogs, and peripheral lymphocytosis was found in 10 of the 16 dogs. At initial diagnosis or during the disease course, 8 dogs (50%) were affected with demodicosis. Immunohistochemical analysis for CD3, CD20 and CD25 was performed for 6 dogs with TZL; the tumor cells were positive for CD3 and CD25 and negative for CD20. Median overall survival time was 938 days. A watchful waiting approach was adopted for 6 cases (38%), and 5 of the 6 dogs were still alive at the end of follow-up. The clinical course of TZL in dogs is generally indolent; however, many cases develop a variety of infectious and other neoplastic diseases after the diagnosis of TZL. |
