Clear Cell Carcinoma
Clear cell carcinomas of the ovary show a variety of architectural patterns and many different cell types admixed in various proportions. The most common patterns are tubulocystic, papillary and solid, often present adjacent to one another.
The image shows areas of papillary architecture. The papillary fronds arise from the walls of cystically dilated glandular spaces and fill up the lumens. They are variably-sized, have a complex architecture and may have completely hyalinized cores.
