Bellini Duct Carcinoma of the Kidney and Liver Metastasis

Abstract

We present clinical and radiological findings in a case of bellini duct carcinoma. This is a rare and aggressive kidney cancer originating from distal renal tubule. The patient underwent transperitoneal radical nephrectomy and the pathological report certified the diagnosis. Control computed tomography scan showed normal findings. But magnetic resonance imaging showed a heterogenous solid mass that is seen hypointense in T1 weighted imaging and hyperintensity in fat suppressed T2 weighted imaging in the liver. Microscopic examination revealed a deterioration structure, desmoplastic appearance and atypical cells with large hyperchromatic nucleus and evidence nucleolus. The histopathological diagnosis was a metastasis of bellini duct carcinoma.

Öz

Bu vakada Bellini ductus karsinomunun (BDC) klinik ve radyolojik bulgularını sunmaktayız. Bellini duktus karsinomu distal renal tübülden köken alan agresif seyirli bir böbrek tümörüdür. Hastaya transperitoneal radikal nefrektomi uygulandı ve patolojik bugular tanıyı destekledi. Kontrol bilgisayarlı tomografide (BT) normal bulgular izlendi. Fakat manyetik rezonans incelemede (MRI) karaciğerde T1 ağırlıklı sekanslarda hipointens ve yağ baskılı T2 ağırlıklı sekanslarda hiperintens görünümde heterojen solid kitle izlendi. Mikroskopik incelemede detoryasyon gösteren yapılar, dezmoplastik görünüm ve hiperkromatik büyük nükleuslu ve nükleouslu atipik hücreler izlendi. Histopatolojik tanı BDC matastazını doğruladı

Anahtar Kelimeler

• Bellini duktus karsinomu, radikal nefrektomi, heterojen solid kitle, yağ baskılanmış T2 ağırlıklı görüntüleme, dezmoplastik görünüm
