Carcinoma microinvasivo de mama: estudio clinicopatológico de 18 casos

Conclusions Microinvasive breast carcinoma is often overdiagnosed histologically. The implementation of strict morphological criteria and the use of immunohistochemistry may be helpful in the differential diagnosis with DCIS and invasive ductal carcinoma. The incidence of local recurrence and lymph node metastases is low, and it is usually associated with the presence of high grade DCIS with necrosis. Sentinel lymph node biopsy may be indicated in cases of DCIS with microinvasion.
