Primary Benign Fibrous Histiocytoma of the Lung with FDG Involvement

Fibrous histiocytoma is a benign tumoral lesion consisting of fibroblastic and histiocytic cells, accompanied by varying numbers of inflammatory cells, foamy histiocytes and siderophages, and has sheet- or short fascicle-type histomorphology. These tumors are generally localized in the dermis or the superficial subcutaneous tissue. Fibrous histiocytoma of the lung is an extremely rare tumor. This study presents a case that appeared as a nodular opacity in the posteroanterior (PA) lung graphy, which was then considered malignant after computerized tomography and PET-CT scans and operated on. The case was finally reported as primary benign fibrous histiocytoma of the lung after pathological examination.

FDG Tutulumu Gösteren Primer Akciðer Yerleþimli Benign Fibröz Histiositom

Fibröz histiositom, deðiþen oranda inflamatuar hücrelerin, köpüksü histiositlerin ve siderofajlarýn eþlik ettiði, fibroblastik ve histiositik hücrelerden oluþan, histomorfolojik olarak tabakalar ya da kýsa demetler halinde görülen benign tümöral bir lezyondur. Genellikle bu tümörler, dermis ya da yüzeyel subkutan doku yerleþimlidir. Akciðer yerleþimli fibröz histiositom oldukça nadir bir tümördür. Arka-ön akciðer grafisinde nodüler opasite þeklinde ortaya çýkan, bilgisayarlý tomografi ve PET-CT taramalarýnýýn ardýndan öncelikli olarak malign kabul edilip opere edilen ve patoloji sonucu primer akciðer benign fibröz histiositomu olarak bildirilen bir olguyu sunduk.
