Sarcomatoid collecting duct carcinoma: A clinicopathologic and immunohistochemical study of five cases

Vinculin: Its Possible Use as a Marker of Normal Collecting Ducts and Renal Neoplasms with Collecting Duct System Phenotype

“…Recent reports demonstrate that sarcomatoidtype RCCs were derived from various types of renal tumors, such as conventional-, papillary-, and chromophobe-type RCCs and collecting duct carcinoma (22)(23)(24)(25)(26). In the present study, four tumors with sarcomatoid-type RCC originated in three conventional-type (clear cell) RCCs and one collecting duct carcinoma.…”

Fine-needle aspiration of the adult kidney

Collecting Duct Carcinoma

“…Atypical hyperplastic changes and intratubular spread of tumor in the collecting duct epithelium are distinctive and characteristic findings, which support an origin from the distal collecting system [13,15]. Some reports have also described microcystic, papillary and tubular patterns and also sarcomatoid variants [1,9,17]. A group of CDCs described as low-grade cystic CDC by Murphy et al [18] and MacLennan et al [19], shows a tubulocystic architecture with tubular organization and small regular round cysts.…”
