Abstract

Renal medullary carcinoma: a report of three cases Renal medullary carcinoma is a very aggressive malignant epithelial tumor of the kidney. In this study, three cases of renal medullary carcinoma are presented, one of which was diagnosed by nephrectomy and the others with biopsy. Histologically, the tumors were composed of diffuse or glandular architecture accompanying neutrophilic inflam- matory component. The neoplastic cells have plasmacytoid or rhabdoid appearance. Immunohistochemically, the neo- plastic cells showed positivity with epithelial membrane antigen, vimentin, Cam5.2, pancytokeratin AE1/AE3 and focally cytokeratin 7 and p53, and showed negativity with Her2neu (c-erb-b2), CEA, high molecular weight cytokeratin (34ßE12) and cytokeratin 20. Two of the patients died with- in the first year after diagnosis. Renal medullary carcinoma is different from other renal carcinomas by histogenesis, diagnosis and treatment. In this report, three cases pre- sented are discussed along with the cases in the literature.

Özet

Renal medüller karsinom böbreğin çok agresif seyirli malign epitelyal tümörüdür. Bu çalışmada biri nefrektomi, diğerleri ise biyopsiden tanı almış üç renal medüller karsinoma olgusu sunulmaktadır. Histolojik olarak tümörler, nötrofilik inflamatuvar komponentin eşlik ettiği diffüz ya da glandüler yapılardan oluşmuştu. Tümör hücreleri plazmositoid veya rabdoid görünümdedir. İmmünohistokimyasal olarak neoplastik hücrelerde epitelyal membran antijeni, vimentin, Cam 5.2, pansitokeratin (AE1/AE3) pozitifliği, fokal olarak sitokeratin 7 ve P53 pozitifliği gözlenirken, Her2neu (C-erbb2), CEA, yüksek moleküler ağırlıklı sitokeratin (34ßE12) ve sitokeratin 20 negatiftir. İki olgu tanıdan sonraki bir yıl içinde ölmüştür. Renal medüller karsinom histogenez, tanı ve tedavi yönüyle diğer böbrek karsinomlarından farklıdır. Bu yazıda sunulan üç olgu literatürdeki olgularla birlikte tartışılmaktadır.
