Cutaneous Melanomas of the Eyelid

Cutaneous eyelid melanomas are very rare lesions. The lentiginous subtypes are the most frequent melanocytic lesions of the eyelid and can be likened to conjunctival melanocytic lesions like PAM, PAM with atypia and conjunctival melanoma. Compared to melanomas elsewhere on the body, eyelid melanomas have special considerations. Eyelid skin is very thin, the mucocutaneous junction at the lid margin can affect prognosis, the lymphatic drainage pattern is very variable and there is an inherent difficulty to excise wide margins without sacrificing important structures. A customized excision approach, using tissue-sparing "Slow-Mohs" technique, is suggested. Sentinel lymph node dissection has an evolving therapeutic role but remains controversial.
