✦ Synopsis

Five cases of histologically confirmed grade 1 papillary transitional cell carcinoma of the renal pelvis investigated by needle aspiration biopsy cytology were reviewed. In all cases the needle aspirates were hypercellular. Abundant benign-appearing urothelial cells in thick clusters, in small aggregates, and singly were seen in two cases. Numerous single and loosely aggregated urothelial cells with cytoplasmic extensions and slightly pleomorphic nuclei were noted in one case. In two patients numerous urothelial fragments of variable sizes showing defined cytoplasm and mildly nuclear pleomorphism were the main cellular findings.

Low-grade adenosquamous carcinoma of the breast (LASCB) is a relatively recently-described, rare histotype of breast cancer that has a favorable prognosis. Its principal microscopic features are the presence of ''syringoid'' (''tadpole''-shaped) ductal profiles of tumor cells, a bland and modestly c

The cytologic features derived from a fine-needle aspiration of polymorphous low-grade adenocarcinoma (PLGA) of the base of the tongue are described. The tumor cells were composed of cuboidal epithelial cells and short, spindle-shaped myoepitheliallike cells, and they formed large cell clusters. In
