Cytologic features of mucinous cystadenocarcinoma. (A) A few scattered, variably sized, irregular clusters of columnar cells with pleomorphism and anisocytosis in a greenish blue mucinous background and necrotic debris. (B) The cells contain abundant mucin vacuoles in cytoplasm that attenuate and displace their nuclei. The nuclear membrane is irregular and sharply angulated and the nuclei reveal a coarse chromatin pattern with prominent nucleoli.
