*Low-grade lesions previously designated “papillary adenoma” | |||
*High-grade lesions previously designated “noninvasive papillary carcinoma.” | |||
*Oten arise in a background of pyloric-gland metaplasia. | |||
*May be associated with invasive adenocarcinoma, which should be reported as intracystic papillary neoplasm with an associated invasive carcinoma and staged. | |||
