Abstract

Bladder cancer is the second most common urological neoplasm of the genitourinary tract, with an increasing incidence in industrialized and developed countries. Massive calcification of bladder tumors are rarely seen on plain radiographs and this appearance may be confused with bladder stones. In this report, we presented a 53-year-old man who was operated on with the diagnosis of a bladder stone seen as a large opacity in the pelvic region on plain radiograph. In exploration, two papillary tumors were found, 10 cm and 2 cm in diameter. The tumors were resected totally. On pathological examination, the tumors were diagnosed as transitional cell carcinoma. Turkish Başlık: Radyolojik Olarak Mesane Taşını Taklit Eden Dev Mesane Tümörü Anahtar Kelimeler: Mesane tümörü, Mesane taşı, Kalsifikasyon Kalsinoz/radyografi; karsinom, geçiş hücreli; tanı, ayırıcı; mesane taşı/tanı; mesane tümörü/radyografi Mesane kanseri genitoüriner sistemin en sık görülen ikinci neoplazisidir ve endüstriyel olarak gelişmiş ülkelerde giderek daha fazla görülmektedir. Mesane tümörlerinde yaygın kalsifikasyon oluşumu nadirdir ve bu görünüm mesane taşları ile karıştırılabilir. Bu yazıda, düz üriner sistem grafisinde pelvik bölgede görülen büyük bir opasite ile mesane taşı tanısıyla ameliyata alınan, cerrahi eksplorasyonda büyüklüğü 10 cm ve 2 cm olan iki papiller tümör saptanan 53 yaşında erkek hasta sunuldu. Tümüyle çıkarılan tümörlerin patolojik tanısı düşük dereceli geçiş hücre karsinomu olarak kondu.
