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...

BACKGROUND Lymphatic drainage to multiple basins (MLBD) is frequently observed in patients with primary melanoma located in the trunk. Conflicting data regarding the prognostic impact of MLBD are reported. OBJECTIVE AND METHODS We reviewed our case series of 352 patients with trunk melanoma to evaluate the pattern of basin drainage and to analyse whether different basin drainages may have dif...

OBJECTIVES To assess whether an association exists between drainage to multiple basins and lymphatic metastasis in patients with truncal melanoma. METHODS We retrospectively reviewed 227 patients with primary malignant melanoma between January 2006 and December 2009. All patients received an intradermal injection of (99m)Tc-nanocolloid and lymphoscintigraphy followed by sentinel node biopsy. ...

BACKGROUND The prognostic significance of multiple draining basins is controversial in melanoma because analyses have not adequately controlled for standard prognostic variables. We hypothesized that an analysis based on prognostically matched pairs of patients with multiple versus single drainage basins would clarify any independent role of basin number. STUDY DESIGN We identified patients i...

OBJECTIVE To determine the impact of multiple lymphatic channels (MLCs) on outcome in melanoma. DESIGN Retrospective cohort study. SETTING Academic tertiary care center. PATIENTS Of 1198 consecutive selective sentinel lymphadenectomies performed from 1995 to 2000 for primary invasive melanoma, 502 patients were identified with extremity or truncal melanoma that drained to a single nodal b...

OBJECTIVE The rising incidence of melanoma and the high prevalence of breast cancer have generated a new scientific problem-how do the regional lymph node basins function after radical lymphadenectomy and are lymphatic drainage patterns altered after radical lymphadenectomy? Furthermore, after radical lymphadenectomy, selective sentinel lymphadenectomy is still a technically feasible and valid ...

Background. Recent studies have demonstrated that there exists a great variation in the lymphatic drainage in patients with malignant melanoma. Some patients have drainage to lymph nodes outside of conventional nodal basins. The lymph nodes that exist between a primary melanoma and its regional nodal basin are defined "interval nodes". Interval node occurs in a small minority of patients with f...
