Enhanced Histopathology of the Lymph Nodes

Histopathology of regression of tumor metastasis in the lymph nodes.

A transplanted rat lymphosarcoma (SGT-4), induced by Gross virus and inoculated s.c. into the foot of a normal syngeneic rat, initially grew but ultimately regressed. The tumor cells metastasized to the regional popliteal, lumbar, and inguinal lymph nodes and formed massive metastatic foci there. These lymph node metastases also regressed spontaneously. However, in Gross-tolerant rats inoculate...

Contrast enhanced ultrasound of sentinel lymph nodes

Sentinel lymph nodes are the first lymph nodes in the region that receive lymphatic drainage from a primary tumor. The detection or exclusion of sentinel lymph node micrometastases is critical in the staging of cancer, especially breast cancer and melanoma because it directly affects patient's prognosis and surgical management. Currently, intraoperative sentinel lymph node biopsies using blue d...

The Relationship of gravidity with the Frequency of Removed Lymph Nodes in Mastectomy and Involved Lymph Nodes after the Surgery in Women with Breast Cancer

Abstract Background: Breast cancer is the most common fatal cancer among women worldwide and it has an increasing rate in Iranian women. The aim of this study was to determine the relationship of gravidity with removed lymph nodes and involved lymph nodes after mastectomy surgery in women with breast cancer. Methods: In this ...

Comparative histopathology of the lymph nodes, spleen, liver and kidney in experimental ovine trypanosomosis.

The infection of Yankassa rams with three important trypanosome species affecting livestock, namely, Trypanosoma congolense, T. vivax and T. bruceiproduced both acute and chronic fatal conditions. Chronic infections were induced in the three infections by the application of subcurative doses of diaminazene aceturate (Berenil). Pathological changes in the infected animals included splenomegaly a...
