Previous reports have shown that 99m sestamibi(MIBI)could detect clinically occult metastatic melanoma lesions. This article reports on a patient with invasive melanoma of the right heel in whom the sentinl node status was preoperatively evaluated with this trace. Although regional lymph nodes were clinically negative, 99mTc MIBI scintigraphy showed focal increased tracer uptake in the right groin that corresponded to the location of 2 sentinel nodes visualized by lymphoscintigraphy with 99m Tc-colloidal rhenium sulfide performed the same day. A y-probe was used intraoperatively to guide the excision of the sentinel nodes that were further classified as metastatic by histopathology. This double.technique approach is technically feasible and has the potential of selecting a groups of patients who might benefit from a selective complete lymphadenectomy
