[Use of intraoperative lymphoscintigraphy in doubtful cases of sentinel node detection]

Lymphoscintigraphy is a widely accepted method used to detect selectively the sentinel node in malignant melanoma. This is the case report of a patient who was operated on for an inguinal melanoma and who was referred to the Nuclear Medicine Section for preoperative lymphoscintigraphy. There were technical problems for sentinel node detection due to the proximity of injection points. We aimed to know the possibility to perform an intraoperative lymphoscintigraphy as a valid and useful technique in cases as this one.
