Intraductal papillomas (IDPs) are benign tumors found within breast ducts. Clinicians should be familiar with IDPs given their association with atypical and neoplastic lesions. In our case, the patient was initially diagnosed with and treated for an abscess given clinical symptoms of breast pain, erythema, and swelling, but upon returning to the clinic a year later due to persistent symptoms, she was found to have an IDP. This case underscores the importance of atypical imaging features and close follow-up when evaluating breast lesions.

Squamous cell carcinoma was found in association with extensive and progressive oral papillomas in a 1 1/2-year-old male beagle. The neoplasm was in the region of the posterior portion of the right law and evidently originated from the adjacent papillomatous growths. Possible relationship between the duration and extent of papillomatosis and the appearance of malignant change, heretofore not reported, is discussed.
