Lymphatic mapping for Merkel cell carcinoma

Abstract

Merkel cell trabecular carcinoma of the skin has a prognosis poorer than expected for a small skin lesion. An early diagnosis and prompt treatment can contribute to improve survival in cases of this aggressive skin tumor. A wide local excision is indicated for localized disease. Elective lymph node dissection is controversial. The authors report a rare case of Merkel cell tumor treated with wide local excision and sentinel lymph node biopsy.
