The second group comprises the less common types: collecting duct carcinoma
, multilocular cystic renal neoplasm of low malignant potential, mucinous tubular spindle cell carcinoma, acquired cystic disease-associated RCC, and tubulocystic RCC.
More than 20 types of cancer have been treated in this trial, including Merkel cell, parotid gland, colorectal, endometrial, ER+ and triple-negative breast cancer, esophageal, collecting duct carcinoma
, ovarian, Hodgkin's disease, hemangioepithelioma and other cancers.
Major histopathological subtypes include clear cell carcinoma, papillary carcinoma, chromophobe carcinoma, collecting duct carcinoma
, medullary carcinoma, and unclassified categories .
Subtypes of renal carcinoma include clear cell, papillary, chromophobe, medullary, and collecting duct carcinoma
. Chromophobe carcinoma (ChC) comprises approximately 5% of all renal cell carcinomas (RCC) .
Only six cases of tubulocystic carcinoma that derived from the bile duct have been reported as subtype of the collecting duct carcinoma
of the kidney in abstracts of the 102nd United States and Canadian Academy of Pathology (USCAP) annual meeting in 2013, and the details of the entity are unknown.
One case each of collecting duct carcinoma
and RCC with oncocytic features was encountered.
(3) Transitional cell carcinoma, renal lymphoma, and collecting duct carcinoma
may present with a central location and an infiltrative pattern.
Collecting Duct Carcinoma
(CDC) is a rare form of RCC that arises from the epithelium of Bellini ducts, located in the distal collecting duct of the renal medulla.
It is challenging to differentiate MTSCC from other renal cell carcinoma subtypes that exhibit comparable morphologic features, but have a less favorable prognosis--namely papillary renal cell carcinoma, collecting duct carcinoma
, metanephric adenoma or sarcomatoid carcinomas.
Prospective multi-center phase II study of gemcitabine plus platinum salt for metastatic collecting duct carcinoma
: Results of a GETUG (Groupe d'Etudes des Tumeurs Uro-Genitales) study.
Previously referred to as 'low-grade collecting duct carcinoma
' or 'Bellinian epithelioma', tubulocystic renal cell carcinoma (TC-RCC) is a unique, recently identified subtype of renal cell carcinoma.
LELCs are distinguished from collecting duct carcinoma
by the absence of desmoplasia and marked cytological atypia.
