Abstract

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

Highlights

  • Conjunctival melanoma (CM) is a very rare malignancy, with an incidence of less than one per million cases per year

  • We believe based the available evidence that sentinel lymph node mapping (SLNM) and SNLB is feasible, accurate, with a low complication rate in patient with CM

  • Micro-metastasis through the lymphatic system can only be detected with sentinel lymph node mapping (SLNM) and sentinel lymph node biopsy (SLNB) [6]

Summary

Introduction

Conjunctival melanoma (CM) is a rare malignancy with an incidence of 0.15 to 0.49 cases per million persons per year [1,2]. We identified two pigmented lesions, one of approximately 1 cm in size and another of approximately 2 cm in size Both lesions had irregular borders, one was in the temporal region, and the other on the nasal region of the eye (Figure 1). The ophthalmology-oncology team performed the resection and the head and neck team, performed the SLNM and SLNB which included a superficial parotidectomy with identification and preservation of the facial nerve (Figure 2). Performed the excision and the head and neck team performed the SLNM and SLNB which included a superficial parotidectomy with identification and preservation of the facial nerve (Figure 4). The final pathology report showed a complete resection with negative margins and the SLNB was negative She is free of disease without evidence of recurrence
