Cytomorphological features of papillary cystadenocarcinoma of parotid gland: A case report with review of literature.
Papillary cystadenocarcinoma is a very rare slow growing malignant neoplasm characterized by cysts and intraluminal papillary projections. It is defined by WHO as a separate entity. On FNA, cytological features can mimic with various papillary and cystic neoplasms of salivary gland. It is also difficult to distinguish from benign salivary gland neoplasms as it has bland nuclear features. Thus we present cytomorphological features and discuss its differential diagnosis with neoplasms having prominent papillary architecture with review of literature.
