Papillary lesions of the mamma. Presentation of a series and review on the theme

Abstract

The papillary lesions of the mamma are a group of heterogeneous tumors growing inside lactiferous ducts, varying from benign lesions as the benign ductal papillomas, to malign entities. We made a transversal, retrospective study on the papillary lesions of the mamma in the General Surgery Service of the University Hospital “Dr Mario Muñoz Monroy”, of the municipality of Colon, in the province of Matanzas, during the period from January 1980 to December 2005 (26 years), finding 36 papillary lesions of the mamma; 18 of them were identified as benign intracanal papillomas, 4 as in situ papillary ductal carcinomas and 14 as invasive papillary carcinomas. We found that benign intracanal papillomas of the mamma had an incidence of 0.56 % of all the mamma's surgical pathologies, having malign papillary neoplasias an incidence of 3.3 % among the operated mammary malign neoplasias (188/530). The average age when intracanal papillomas appear was 49 years old, while malign papillary lesions appear at the age of 55. 100 % of the intracanal papillomas began by a hemorrhagic secretion through the nipple (telorragia), while most of the malign papillary lesions were discovered as a palpable tumor. In relation with the treatment, a block resection including the affected conduct is enough for the benign affections; for the malign lesions, the modalities cover from a surgery preserving the mamma to a Merola- Patey's Modified Radical Mastectomy.
