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...

Basosquamous carcinoma of the skin is a relatively rare cutaneous neoplasm that has significant metastatic potential and a metastatic rate greater than that of basal cell and squamous cell carcinoma. We describe the use of lymphatic mapping and sentinel lymph node biopsy in a 63-year-old man after identification of basosquamous carcinoma. Sentinel lymph node biopsy, which is a standard tool to ...

BACKGROUND We reviewed the available literature on the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers. METHODS MEDLINE and Scopus were searched by using "sentinel AND (cervix OR cervical)" as key words. Studies evaluating the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers were included if enough data could be ...

BACKGROUND For accurate nodal staging, all blue and radioactive lymph nodes should be sampled during the sentinel lymph node biopsy for breast cancer. We report a case of anomalous drainage in which one of the sentinel lymph nodes was unexpectedly found in the level III axillary space. CASE PRESENTATION A 40-year-old female underwent mastectomy for extensive high-grade ductal carcinoma in-sit...

We present a patient with malignant melanoma on his heel. Wide local excision was performed, along with sentinel lymph node biopsy of the inguinal and popliteal lesions. The primary site was clear of tumor at all margins; the inguinal nodes were negative, but the popliteal node was positive for metastatic melanoma. Only radical popliteal lymph node dissection was performed. The patient went on ...

BACKGROUND The prognostic value and clinical implication of micrometastases and isolated tumor cells (ITCs) in sentinel lymph nodes are still not clearly defined. This study was designed to collect clinical pathological data in our Institution. PATIENTS AND METHODS Twenty-five cases of micrometastases and nine cases of ITCs were identified among 1,000 sentinel lymph node biopsies performed at...

OBJECTIVE A significant morbidity risk is associated with axillary nodal dissections for breast cancer. Many treatment decisions are based on axillary nodal status. Lymphatic mapping and sentinel node biopsy have been investigated to determine if the histology of the sentinel node reflects the remaining lymph node basin. We describe the technical aspects of sentinel node lymphoscintigraphy for ...

The worldwide incidence of malignant melanoma is increasing at an alarming rate. The importance of diagnosing nodal metastatic disease has impacted significantly on the accurate staging and stratification of melanoma patients. As a minimally invasive procedure with low morbidity, sentinel lymph node mapping allows for a detailed histopathologic evaluation involving multiple sections, H&E staini...

The use of sentinel lymph node biopsy for the T1 melanoma is controversial. Recent reports have demonstrated that certain T1 melanomas are at increased risk for early regional metastases and late recurrence when compared with all thin melanomas. The purpose of this study was to review the authors' experience with wide excision and sentinel lymph node biopsy for certain patients with T1 melanoma...

OBJECTIVE To define the percentage of positive sentinel lymph node biopsies and identify risk factors for the presence of lymph node disease in patients with melanomas less than or equal to 1 mm in depth. DESIGN Retrospective chart review. SETTING Washington University School of Medicine and Barnes-Jewish Hospital, St Louis, Mo, a melanoma referral center with outpatient surgical care. PA...
