RESUMEN
OBJECTIVE: To show the incidence, as well as the clinical and histopathological characteristics, of patients diagnosed with mammary salivary gland-like carcinomas at our institution. MATERIALS AND METHODS: A retrospective study was conducted in all women diagnosed with breast cancer at our institution from January 2005 to February 2016. Patients with diagnosis of salivary gland-like breast carcinomas were included. RESULTS: In this period, 6384 patients were diagnosed with breast cancer at our institution; salivary gland-like carcinomas were found in 7 patients (0.1%), adenoid cystic carcinoma was diagnosed in 5 patients (0.07%), acinic cell carcinoma in 1 patient (0.015%) and mucoepidermoid carcinoma in 1 patient (0.015%). The triple-negative subtype was found in all of the tumors. Median follow-up was 66.3 months (range, 1-108 months). No patient developed local or distant recurrence. CONCLUSIONS: Salivary gland-like breast tumors are extremely rare. We found a global incidence of 0.1%. Adenoid cystic, acinic cell and mucoepidermoid carcinomas were the three histologic types diagnosed. Although the triple-negative subtype is mainly found, good prognosis is expected.

BACKGROUND: Breast cancer is the leading oncological cause of death in Mexican women over 25 years old. Given the need to improve postoperative cosmetic results in patients with breast cancer, oncoplastic surgery has been developed, which allows larger tumour resections and minor cosmetic alterations. OBJECTIVE: To determine the oncological feasibility and cosmetic outcome of oncoplastic surgery at the Instituto de Enfermedades de la Mama, FUCAM, AC. MATERIAL AND METHODS: A review was conducted from January 2010 to July 2013, which included patients with breast cancer diagnosis treated with conventional breast-conserving surgery or with oncoplastic surgery in the Institute of Diseases of the Breast, FUCAM AC. Clinical and histopathological parameters were compared between the two groups, and a questionnaire of cosmetic satisfaction and quality of life was applied. RESULTS: Of the 171 patients included, 95 of them were treated with conventional breast-conserving surgery and 76 with oncoplastic surgery. Pathological tumour size was significantly larger in patients treated with oncoplastic surgery (p = 0.002). There were no differences found between the groups as regards the number of patients with positive surgical margin, the rate of complications, and cosmetic satisfaction. CONCLUSION: This study demonstrates the oncological feasibility and high cosmetic satisfaction of oncoplastic surgery with minimal psycho-social impact on patients.
