Parotis Bezinin Primer Malign Melanomu: Alışılmadık Primer Alan

Öz

Parotis bezinin malign melanomu alışılmadık bir lokalizasyon olup literatürde nadiren bildirilen istisnai bir durumdur. Farklı tedavi ve prognozlarından dolayı parotis bezinin primer malign melanomu ile malign melanomun parotise metastazının ayırımı kritiktir. Biz sağ parotiste şişlik ile başvuran 57 yaşındaki bir kadın hastayı sunduk. Hastaya sağ parotidektomi yapıldı. İmmünhistokimyasal olarak tümör hücreleri S-100, HMB-45 ve Melan A ile pozitif boyanıyordu. Değerlendirmede primer olabilecek başka bir odak bulunmadığından hastaya parotis bezinin primer malign melanomu teşhisi konuldu.Parotis bezinin malign melanomu nadir bir teşhis olmakla birlikte, klinisyenler parotis tümörlerinin farklı teşhisinde bu prezentasyonun farkında olmalıdır

Abstract

Malignant melanoma MM of the parotid gland arising at such an unusual location is an exceptional and rare case only occasionally mentioned in the literature. Due to the different treatments and prognosis, a distinction between primary parotid gland MM and metastasis of MM is crucial.We report on a 57-year-old woman who presented with right parotid swelling.She underwent right total parotidectomy. Immunohistochemically, the tumor cells were positive staining for S-100, HMB-45, and Melan A. Since no other focus was detected, the patient was diagnosed with primary malignant melanoma of the parotid gland. Although malignant melanoma of the parotid gland is a rare diagnosis, clinicians should be aware of this presentation in the differential diagnosis of parotid tumors
