Merkel Cell Carcinoma of the Eyelid

Abstract

The majority of patients with MCC of the eyelid present with localized eyelid disease of T category T2 (eyelid TNM)/T1 (Merkel TNM). A wide local excision with margin control remains the mainstay of treatment, whereas the use of radiotherapy is institution specific. Tumors with a low T category are associated with regional nodal and distant metastatic disease. It may therefore be reasonable to consider a sentinel lymph node biopsy or strict regional lymph node surveillance for all MCCs of the eyelid, regardless of T category or size.
