Mucinous carcinoma is a rare type of breast cancer, which represents less than 4% of all primary cancers. It usually occurs in postmenopausal patients, around the seventh decade of life. Clinically, it is characterized by the presence of a palpable nodule, rarely accompanied by other symptoms.

Imaging tools, such as mammogram and ultrasound, are essential for its diagnosis, however, in some situations the diagnosis can be underestimated due to the similar characteristics that it shares with other benign lesions. Definitive diagnosis is made by histopathology.

Regarding treatment, there is no consensus on the most appropriate, due to the low incidence of these tumors. Many authors agree that surgical intervention continues to be the best option, showing a positive impact on survival and low recurrences. This can be accompanied later by adjuvant endocrine therapies. Fortunately, the prognosis of this type of tumor is usually favorable, even survival exceeds 90% at 5 years.

Palabras llave : Breast cancer; mucinous carcinoma; clinicopathological features; histological subtypes.
