the gastrointestinal stromal tumor (gist) is a rare mesenchymal tumor of gastrointestinal (gi) tract. this tumor has tendency to liver metastasis and peritoneal recurrence, however; the primarily lymph node involvement or metastasis is rare. here we reported a 17-years-old girl with multifocal gastric gist and multiple lymph node involvement at presentation and recurrence in celiac lymph nodes....

Background and Objectives: Involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. In the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. The aim of this study was determination of the relationship between the size of col...

lymph node status remains an important prognostic indicator for survival in breast cancer. sentinel lymph node biopsy has become the standard method of assessment of clinically node negative breast cancers. economic implications as well as patient related factors have lead to the development a number of intra-operative techniques. review of the emerging trends in the last 4 years show that alth...

abstract castleman disease or giant node hyperplasia is a rare disorder of the lymphoid tissue most often involving the mediastinal lymph nodes. we report a case of localized retroperitoneal hyaline-vascular type of castleman disease. a 35-year old woman presented with mild epigastric pain with radiation to the back. amild anemia was the only abnormal associated finding. abdominal ultrasound an...

Background: Breast cancer is the most commonly diagnosed and the leading cause of cancer death among females worldwide. The rate of breast cancer incidence among Iranian women is 17% of all cancers, it has been ranked first in Iran. This study aimed to investigate the factors affecting axillary lymph node involvement in female patients with breast cancer. Methods: A cross-sectional study was c...

Background: The purpose of this study was to assess the dose distribution and coverage of level Ⅰ-Ⅱ axillary lymph nodes during whole breast tangential field radiotherapy (RT) after breast-conserving surgery in patients with breast cancer. Materials and Methods: The level Ⅰ-Ⅱ axillary lymph node volumes were retrospectively contoured by a single radiation oncologist based on computed tomography...

OBJECTIVE To create a reference map of mediastinal lymph nodes through the analysis of their size, number and distribution in various lymph node stations. METHOD A total of 50 cadavers, 38 males and 12 females, were studied. Of those 50, 39 were Caucasian. The mean age was 59.9 +/= 14.1 years, the mean height was 173.1 +/= 7.6 cm, and the mean weight was 71.0 +/= 12.0 kg. A bilateral mediasti...

Lymphatic filariasis is endemic to tropical countries and is the most common cause of acquired lymphedema in the world. Wuchereria bancrofti is the main etiological agent responsible. While the presentation of filariasis in limbs is common, isolated presentation as a single enlarged lymph node in the neck is very rare. We describe a 48-year-old Indian woman, who presented with a hard lymph node...

Introduction: The applicability of sentinel lymph node biopsy for early detection of metastasis in patients with renal cell carcinoma (RCC) is still in the validation phase and under investigation, which might be due to the unpredictability of the lymphatic pattern in RCC. In this study, we aimed to evaluate the feasibility and accuracy of sentinel node biopsy in patients with ...
