Epitrochlear Lymph Node Dissection.
Summary of "Epitrochlear Lymph Node Dissection."
Epitrochlear node involvement occurs in a small minority of patients with forearm or hand melanoma. Although in-transit sentinel lymph nodes are identified infrequently, they contain metastatic disease at nearly the same frequency as sentinel lymph nodes in cervical, axillary, and inguinal nodal basins. Positive in-transit sentinel lymph nodes are likely to be the only site of nodal metastasis. Therefore, detailed preoperative lymphoscintigraphy and meticulous intraoperative search for in-transit nodes should be performed. The recovery of nodes from in-transit nodal areas is low; however, there appears to be an increase in the performance of these dissections since the advent of lymphatic mapping and sentinel lymph node biopsy. This streaming video demonstrates the incidence of epitrochlear lymph node involvement and technical considerations associated with epitrochlear lymph node dissection.

Sentinel Lymph Node Biopsy
A diagnostic procedure used to determine whether LYMPHATIC METASTASIS has occurred. The sentinel lymph node is the first lymph node to receive drainage from a neoplasm.
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the LYMPH NODES. The nodules resemble to some extent the GERMINAL CENTER of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular center B-LYMPHOCYTES.
Local Lymph Node Assay
The local lymph node assay (LLNA) is an alternative method for the identification of chemicals that have the ability to cause skin sensitization and allergic contact dermatitis. Endpoints have been established so fewer animals are required and less painful procedures are used.
The historic designation for scrofula (TUBERCULOSIS, LYMPH NODE). The disease is so called from the belief that it could be healed by the touch of a king. This term is used only for historical articles using the name "king's evil", and is to be differentiated from scrofula as lymph node tuberculosis in modern clinical medicine. (From Webster, 3d ed)
The mainstay of surgical therapy for rectal cancer is colectomy (including lesions) with lymph node dissection. The lymphatic spread of rectal cancer can proceed in two directions: medially toward the...
INTRODUCTION: We evaluated the incidence of micrometastasis and nonsentinel lymph node metastasis as well as local and axillary recurrence rates after level I-II axillary lymph node dissection. MATERI...
Complete axillary lymph node dissection has been the traditional operation to determine whether cancer has spread beyond the breast. In the large majority of patients with breast cancer, lymphatic map...
Sentinel lymph node biopsy has become a standard component of the evaluation of early-stage breast cancer, with a gradually increasing number of indications in this patient population. This report pre...
PURPOSE:: We determined the incidence of antegrade emission after primary retroperitoneal lymph node dissection in a large contemporary cohort. Our secondary purpose was to evaluate the fertility rate...
Occult lymph node metastasis is common in micro papillary thyroid cancer. However, the role of lymph node dissection in the treatment of microPTC remains controversial. The investigators w...
Aim of present study is to inspect, if the removal alone of sentinel lymph nodes in women with early Cervix Carcinoma lead to, at equal length, overall survival like entire systematic diss...
The Purpose of This Study: In case of urothelial carcinoma of the upper urinary tract (a cancer originating from the inner lining of the urinary tract) requiring the removal of the kidney...
The purpose of this study is to evaluate a less invasive procedure for the evaluation of the inguinal (groin) nodes in patients with a primary squamous cell carcinoma of the vulva. Each pa...
RATIONALE: The use of axillary drains may help to prevent complications following axillary lymph node dissection. PURPOSE: This randomized clinical trial is comparing three methods of axi...
