Sclerosing adenosis in sentinel axillary lymph nodes from a patient with invasive ductal carcinoma: an unusual variant of benign glandular inclusions.
Benign glandular inclusions in axillary lymph nodes are very rare events that have to be distinguished from metastatic carcinoma. We report an exceptional instance in which a patient with invasive ductal carcinoma had benign glandular inclusions in the form of sclerosing adenosis in 2 sentinel lymph nodes. The lymph nodes did not contain metastatic carcinoma. Immunohistochemical studies facilitated the correct diagnosis.
