The name comes from finger-like projections, or papules , which are seen when the cells are looked at under the microscope. Many papillary tumors are benign. These are called papillomas. Even when a biopsy is negative for cancer, the pathologist often needs to look at the whole tumor under the microscope to be sure about the diagnosis. This is why surgery to remove a papilloma is usually recommended, even if it is thought to be benign.
Papillary Carcinoma of the Breast: Symptoms, Causes, Diagnosis, and Treatment
It is well known that certain types of pre-malignant lesions can predispose some women to increased risk of breast cancer. These certain types of pre-malignant lesions are generally classified as high-risk breast lesions. These lesions are morphologically, radiologically, histologically and clinically heterogeneous and early identification can help to prevent progression to invasive cancers. The management of these lesions has been debated internationally for years by experts as to the best treatment modality with surgical excision of the lesion often not considered necessary. It is thus important to evaluate each patient on an individual case-by-case basis.
Colleague's E-mail is Invalid. Your message has been successfully sent to your colleague. Save my selection. The majority are benign. The few that are malignant can be distinguished by the monomorphic morphology of the enlarged cells and by the absence of cytokeratin 5 positively stained neoplastic cells within the lesion.
Papillary lesions of the breast include a broad spectrum of lesions, from benign papillomas to papillary carcinomas. It is difficult to determine whether a lesion is benign or malignant based on the fragmented material of a core needle biopsy CNB. This study evaluated patients with papillary lesions examined using CNB. We retrospectively reviewed 31 papillary lesions diagnosed using CNB between and
