RESUMEN
The authors report 13 cases of myoepithelial cell proliferation in the breast. One of them is a neoplasm with a predominant myoepithelial component. These proliferations in mastopathies or neoplasms raise important questions concerning differential diagnosis with invasive adenocarcinoma and prognosis.

The authors report a case of primary bilateral adenocarcinoma of the fallopian tube in a woman with invasive ductal carcinoma of the breast in her antecedents. The tubal carcinoma was in situ or invasive and appeared as a bilateral hydrosalpinx, fact which often happens in the literature. Gross examination showed a tumoral mass of about 2 cm diameter at the fimbriated end of the right tube, the diagnostic of bilaterality requiring serial cuts on the left tube. The electron microscopic study showed ciliated differentiation in the neoplastic cells, bearing out the primitive nature of the proliferation.

In a retrospective study, the authors have observed different types among 180 breast invasive carcinomas, their environment and their epidemiology. Tumors consisted in 158 invasive ductal carcinomas, 11 invasive lobular carcinomas and 11 special forms. The benign environment was divided in 3 groups: no epithelial lesion (1/5 cases), "mastosis simple" (3/5) (elementary lesions more or less associated, exceptionally isolated, diffuse or focal), the last, 1/5, corresponded to a "mastosis complex" defined as the significant association of the same elementary lesions (minimum 3 to 4), diffuse, with some degree of dysplasia and always an intraductal hyperplasia, of any type. The confrontation of these environments with carcinoma types and grades and with some epidemiological data allowed: 1) To opposite intraductal hyperplasias, mainly "mastosis complex", to other environments; 2) to discuss a) "mastosis complex" position in relation to cancer, b) an eventual lobular origin for precancerous lesions and c) individualization of epidemiological factors in relation to development of malignant tumors.
