Abstract

We report a 20-year-old male patient with an atypical Spitz tumor, located in the dorsal aspect of his left hand, and a positive sentinel axillary lymph node. After lymphadenectomy, 1 of 23 non-sentinel lymph nodes excised was found to contain small multiple deposits of large spindle atypical melanocytes. Reviewing the pertinent literature, 5 of 29 patients with atypical Spitz tumors and positive sentinel nodes who had undergone lymphadenectomy have shown non-sentinel node involvement (17.2%), a proportion similar to that reported in melanoma patients. The exact nature of atypical Spitz tumors and the interpretation of cell deposits detected in sentinel nodes are still debated; data regarding the non-sentinel lymph node involvement in patients with atypical Spitz tumors may contribute to better understand the real biological potential of such tumors.
