Renal angiomyoadenomatous tumour

Abstract

Renal angiomyoadenomatous tumour is a newly described rare neoplasm. This tumour is characterised microscopically by admixture of three components-epithelial cells arranged in tubules and nests, angiomyomatous stroma and capillary sized interconnecting vascular channels in close association with the epithelial cell clusters. Microscopically it has wide range of differential diagnoses which include mixed epithelial and stromal tumour of kidney, angiomyolipoma and clear cell renal cell carcinoma with angiomyolipomatous/ angiomyoadenomatous areas. Renal angiomyoadenomatous tumour should be differentiated from these tumours. Till now, only 10 cases have been reported in English medical literature. Here, we are reporting a case of renal angiomyoadenomatous tumour in a 29 year-old female patient who presented with hematuria and low backache and describing its main features so as to differentiate this entity from other renal tumours. To the best of our knowledge, this is the first case to be reported from India.

Morphological characteristics and immunophenotype of clear cell renal cell carcinomas

“…Ряд исследователей рассматривают эти новообразования в рамках одной нозологической единицы [18][19]. В нашей работе в двух наблюдениях (0,8%) четко ограниченная опухоль почки серовато-коричневого цвета диаметром 3 см на светооптическом уровне имела трехфазную структуру.…”

Clinical and morphological features, immune profile of renal cell tumors with clear cytoplasm

“…В строме -явления выраженной пролиферации гладкомышечных элементов и микрососудов. По данным литературы, в эпителиоидном компоненте обнаруживается положительная экспрессия к EMA, CK7, CK20, PanCK и CAM5.2 [55,56].…”
