Mapped serial excision for periocular lentigo maligna and lentigo maligna melanoma

Our review is the largest prospective series of MSE for LM and LMM and suggests that it is the treatment of choice in these forms of melanoma. Mapped serial excision offers a high early cure rate in conjunction with tissue conservation, which is of particular relevance in the periocular region. There were no significant differences between periocular LM and LMM and those found elsewhere in the head and neck region. It also appears that the current recommendations of 5-mm margins for in situ melanoma (LM) and 1-cm margins for melanoma less than 1 mm thick are insufficient for complete excision of LM or LMM, emphasizing the importance of margin-controlled excision of these lesions.
