누낭(Lacrimal Sac)의 악성 흑색종 1례

Abstract

Malignant melanoma of lacrimal sac is extremely rare and can present with epiphora, bloody tear, and nasal bleeding. Its current management consists of surgical resection, chemotherapy, radiation therapy, and immunotherapy. The wide-field en bloc resection with removal of the entire nasolacrimal system, especially clearly defined tumor margins, ensures the best protection against recurrence. We present a case of malignant melanoma of lacrimal sac that is spread to inferior meatus and periorbital area. We excised the mass completely via medial maxillectomy including dacryocystectomy, but didn`t accompany adjunctive therapy because the treatment effect remains controversial. To date, after 15 months follow-up, there is no evidence of local recurrence and distant metastasis. A literature review was also done, in addition.
