Malign melanomlu bir hastada yapılan pozitron emisyon tomografide rastlantısal olarak tespit edilen tiroid papiller karsinom [Incidentally detected thyroid papillary carcinoma on PET in a patient with malignant melanoma]
Abstract
Focal or diffusely increased 18F-fluorodeoxyglucose (18FDG) uptake in thyroid gland are occasionally seen during 18FDG positron emission tomography (PET) scanning. Increased 18FDG uptake in thyroid nodules may be associated with benign or malignant tumours. In our case who was diagnosed as malignant melanoma, focally increased 18FDG uptake in a thyroid nodule was noticed. Thus, fine needle aspiration biopsy of the thyroid nodule was performed. On suspicious findings for the thyroid papillary cancer were reported, total thyroidectomy was performed. Histopathological evaluation revealed the thyroid papillary carcinoma. So, therapy for the incidental thyroid papillary carcinoma was commenced in this case who was under the follow-up for the malignant melanoma.

Abstract
18F-Florodeoksiglukoz pozitron emisyon tomografi (18FDG PET) görüntülemede tiroid bezinde difüz ya da fokal artmış 18FDG tutulumu ile zaman zaman karşılaşılmaktadır. Tiroid bezindeki nodüllerde artmış 18FDG tutulumu benign ya da malign tümörlere bağlı olabilir. Malign melanom tanısı bulunan olgumuza tümör evrelemesi amacıyla yapılan 18FDG PET/BT esnasında tiroid bezindeki bir nodülde fokal artmış 18FDG tutulumu dikkati çekti. Bu nodüle yapılan ince iğne aspirasyon biyopsisinde tiroid papiller karsinomu (Ca) düşündüren bulgular rapor edilmesi üzerine hastaya total tiroidektomi yapıldı. Histopatolojik olarak papiller tiroid Ca tanısı koyuldu. Bunun üzerine malign melanom tanısıyla takip ettiğimiz bu olgumuza ilave olarak rastlantısal tiroid papiller Ca tedavisi başlandı.
