Spinal Meningeal Melanositom Olgusu

Leptomeningeal melanositlerden köken alan neoplaziler diffüz ya da lokalize formları bulunan nadir görülen tümörlerdir. Lokalize lezyonlar sporadik olarak iyi diferansiye melanositomlardan potansiyel olarak yayılan melanomlara kadar değişen bir spektrum gösteren meningeal kitleler şeklinde ortaya çıkar. Pek çok tümör sıklıkla posterior fossada, Meckel boşluğunda ve torasik boşlukta yerleşir. Biz bu çalışmada 66 yaşında kadın hastada immünohistokimyasal ve ultrastrüktürel çalışmalar eşliğinde spinal melanositom olgusu sunduk. Tümör spinal kordu infiltre etmiş olup, MIB-1 indeksi %2 oranındaydı. Tümör total olarak eksize edildi. Bu tümörün tekrarlayabileceğini düşündüğümüz halde takip eden 3 yıl içerisinde tümör rekürrensi izlenmedi.

A Case of Spinal Meningeal Melanocytoma

Neoplasms derived from leptomeningeal melanocytes are uncommon lesions that present in diffuse or localized form. Localized lesions present sporadically as meningeal masses and range from well differantiated melanocytomas to malignant, potentially disseminating melanomas. Most tumors commomly occur in the posterior fossa,in Meckel's cave and within the toracic spinal canal. We report one cases of spinal melanocytoma 66 year-old-female with immunohistochemical and ultrastructural studies.Tumor invaded the spinal cord and MIB-1 staining was %2. Tumor was totaly excised. So we tought that this tumor can recur. After 3 year following no recurrence was seen.
