Preoperative cutaneous lymphoscintigraphy in malignant melanoma.
To identify the regional lymph node basins cutaneous lymphoscintigraphy with technetium 99m rhenium sulfide colloid (99mTc-ReS) was performed in 45 patients and with technetium 99m antimony sulfide colloid (99mTc-Sb2S3) in seven patients after excisional biopsy of the primary tumor. All patients had skin tumors located in the face or neck or on the trunk with 47 cases of cutaneous malignant melanoma and 5 cases of benign or premalignant lesions. In 48 patients the scintiscans 1 hour after perilesional injection of the tracer colloid clearly showed the lymphatic drainage patterns from the tumor sites, of them 25 patients demonstrated unidirectional drainage, whereas the remaining 23 patients had multidirectional drainage to two or three lymph node groups. There were technical difficulties in performing the examinations in four patients. The authors recommend cutaneous lymphoscintigraphy as a safe, simple and reliable technique for mapping the lymphatic drainage preoperatively in patients with Stage I cutaneous malignant melanoma of axial localization.
