title: Inclusions of benign nevus cells in the capsule of axillary lymph nodes in three cases of breast cancer.
abstract: Three cases of breast carcinoma are reported in which the capsule of an axillary lymph node contained inclusions of benign-appearing nevus cells. The lesions were exclusively limited to the lymph node capsule without involvement of peripheric sinus or parenchyma. In one case, another lymph node presented a metastasis histologically identical to the primary neoplasm. The differential diagnosis with the carcinomatous metastasis and the possible origin of these inclusions are discussed.
