Polymorphous low‐grade adenocarcinomas are low‐grade malignant salivary‐gland neoplasms with a broad variety of architectural patterns. Whether papillary structures fall within this spectrum or whether they should lead to a diagnosis of papillary low‐grade adenocarcinoma is a subject of debate. This problem was investigated by analyzing a series of 22 salivary gland neoplasms. It was concluded that papillary structures form part of the histologic spectrum of polymorphous low‐grade adenocarcinoma but that there are also tumors with papillary structures as a single component. In most instances these are more properly classified as papillary cystadenocarcinomas. As the designation papillary low‐grade adenocarcinoma has been used for polymorphous low‐grade adenocarcinomas with papillary structures as well as for papillary cystadenocarcinoma, it is advocated that the diagnosis of papillary low‐grade adenocarcinoma should be discontinued.
