Sentinel Lymph Node Biopsy in the Setting of Conjunctival Melanoma: Report of Two Cases and Literature Review

Abstract

Objective: To report two cases of conjunctival melanoma (CM) that underwent sentinel lymph mapping (SLNM) and sentinel lymph node biopsy (SLNB) with good results. Introduction:Conjunctival melanoma (CM) is a very rare malignancy, with an incidence of less than one per million cases per year. Metastatic dissemination may occur via lymphatic or hematogenous routes. The regional lymph nodes most commonly involved in the head and neck region are found in the deep cervical node chain and in the parotid gland. The management of the lymph nodes in patients with CM is debatable with some authors recommending SLNM with SLNB. The indications for performing SLNM and SLNB are CM with a thickness of 1 mm or greater.
