[Mucinous carcinoma of the breast (clinico-morphological characteristics)].

The main criteria for the morphological diagnosis of the "pure" and mixed mucinous carcinoma are established on the basis of studying 83 mucinous carcinomas of the mammary gland. The necessity to differentiate is pointed out between the "pure" from of this carcinoma and the mixed one as the former has a much more favourable prognosis as compared to the latter which, in its turn, has a more favourable prognosis than an infiltrative ductal carcinoma. Total 10-year-survival of patients with "pure" and mixed variants of the mucinous carcinoma is 90.46 +/- 7.27 and 58.29 +/- 11.1, respectively. The radical mammary gland resection is recommended in patients with a "pure" variant of mucinous carcinoma at 1 and 11 A stages of the disease.
