introduction: lymphoscintigraphy is imaging of the lymphatic system and has been integrated into the sentinel node mapping procedures. lymphoscintigraphy usually encompasses early or delayed static images. however, immediate dynamic imaging of the lymphatic basins and tumors has also been used as an adjunct lymphoscintigraphy imaging. the aim of this study was to assess the role of early dynami...

we report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (sln) biopsy.  four peritumoral intradermal tc-99m phytate injection was performed and slns were detected in both axillary and right inguinal regions. on the biopsy only the right axillary sln was metastatic leading to right axilla...

IMPORTANCE A practice gap exists in the surgical removal of sentinel lymph nodes, from removal of only the most radioactive (hottest) lymph node to removal of all lymph nodes with radioactivity greater than 10% of the hottest lymph node. OBJECTIVE To determine the clinical significance of melanoma in sentinel lymph nodes that are not the hottest sentinel node and to determine the risk for dis...

BACKGROUND In patients with clinically node-negative breast cancer, diagnosed with palpation and several types of imaging examination, sentinel lymph nodes accurately predict the status of the other axillary nodes, which determine the nature of subsequent adjuvant treatment. In addition, compared with axillary lymph node dissection, sentinel-node biopsy results in less postoperative morbidity, ...

OBJECTIVE Sentinel lymph node biopsy is the recommended approach in the evaluation of axilla during breast cancer surgery. In this study, results of patients who underwent methylene blue sentinel lymph node biopsy were evaluated. MATERIALS AND METHODS The study included 32 female patients with T1 and T2 tumors. 5 ml of 1% methylene blue was injected into the peritumoral area or around the cav...

OBJECTIVE To establish the prognostic value of knowledge of sentinel node status in melanoma. DESIGN Single centre prospective observational study, with sentinel nodes identified by lymphoscintigraphy, gamma probe, and intraoperative blue dye and examined by both conventional histopathology and immunopathology. SETTING Specialist surgical service in west of Scotland. PARTICIPANTS 482 pati...

BACKGROUND The objectives of the study were to determine how often a sentinel lymph node is visualized by lymphoscintigraphy in breast carcinoma patients, how often the sentinel lymph node is identified during surgery, and the sensitivity of these procedures to identify the presence of axillary lymph node metastasis. METHODS A total of 136 patients were enrolled in 2 hospitals. Preoperative d...

in medicine, patent blue violet (pbv) is utilized for staining lymphatic vessels in sentinel lymph node (sln) surgery. moreover, pbv (also called e131 ) is used as food additive. we report on a 51-year-old non-atopic female with early breast cancer, who was scheduled for sln excision and experienced an intra-operative anaphylactic reaction. in diagnostics the skin prick test (spt) was positive ...
