Intraductal papilloma is a rare benign tumor reported to be primarily in minor salivary gland. There were few reports in parotid gland. A case of a 5-year-old boy with a palpable mass in the left parotid gland, with a review of the literature pertaining to this unusual case. A supeficial parotidectomy was performed under impression of benign or congenital lesion. Histopathologic diagnosis of intraductal papilloma was made on the surgical specimen. Authors report a intraductal papilloma arising from the parotid gland in childhood.

Ductal papillomas are rare benign lesions of the salivary glands with two distinctive types, intraductal and inverted. The rarest anatomical location where intraductal papillomas occur is the major salivary glands. In the present study, we report an intraductal papilloma of the left sublingual gland with the relevant clinical, imaging, and histopathological findings and postoperative follow-up. To our knowledge, this is the fourth case of an intraductal papilloma of a sublingual gland to be reported in the international literature. We present this rare case because of its clinical and radiological imitation of a ranula.

Intraductal papilloma is an extremely rare benign tumor especially when it arises from major salivary gland. Recently, we experienced a case of an intraductal papilloma arising from the parotid gland in a 51-year-old woman. The radiologic finding showed lobulated enhancing and cystic solid mass in the left parotid superficial lobe. Superficial parotidectomy was performed. Pathological findings showed papillary proliferations with fibrovascular cores lined with bland cuboidal or columnar epithelial cells, and immunohistochemical stain results were consistent with intraductal papilloma. We report a case of intraductal papilloma in parotid gland with a review of literature.

Benign and malignant papillary neoplasms of the breast may be difficult to distinguish in both cytologic and histologic preparations. To define the cytologic features of benign and malignant papillary lesions, we retrospectively reviewed 18 cases of fine needle aspirates from histologically confirmed cases of papilloma or papillary carcinoma of the breast. This study included 3 intraductal papillary carcinomas, 3 invasive papillary carcinomas, and 12 intraductal papillomas. Ail cases were evaluated for presence or absence of papillary fragments, bloody background, apocrine metaplasia, macrophages, and degree of cellularity, atypia, and single isolated columnar epithelial cells. Papillary fragments were present in all cases. The background of the smear was bloody in all 6 carcinomas, but in only 7 out of 12 papillomas. Markedly increased cellularity was present in 4 carcinomas(67%) and 7 papillomas(58%). Single cells were present in 5 carcinomas(83%) and 8 papillomas(67%). The majority of papillomas and papillary carcinomas had mild to moderate atypia, and severe atypia was noted in one case of intraductal papillary carcinoma and one case of invasive papillary carcinoma. Apocrine metaplasia was absent in all cases of papillary carcinomas, but present in 8 papillomas(57%). Macrophages were noted in 4 carcinomas and were present in all cases of papillomas. The constellation of severe atypia, bloody background, absence of apocrine metaplasia and/or macrophages were features to favor carcinoma. Malignant lesions tended to show higher cellularity and more single isolated cells. The cytologic features mentioned above would be helpful to distinguish benign from malignant papillary lesions of the breast. However, because of overlapping of cytologic features, surgical excision should be warranted in all cases on papillary lesions of the breast to further characterize the tumor.
