A case of tubulolobular carcinoma, in a 65 years old woman, is presented. The tumor, less than 1 cm in maximum diameter, was discovered during screening mammography. The histological feature of single strands of uniform, small, quite regular tumor cells in a linear or «targetoid» infiltration intermixed with tubular elements, confirmed our diagnosis. Although, there is still a lack of agreement concerning its assignment as a variant of tubular or lobular carcinoma, we regard this uncommon type of breast cancer exhibiting an extremelly good prognosis, as a distinct and separate histopathological entity.
