Nevus Cells within Lymph Nodes: Possible Metastases from a Benign intradermal Nevus

Abstract

Two axillary lymph nodes from a patient who underwent modified radical mastectomy for carcinoma of the breast showed benign nevus cells in the fibrous capsule and within afferent lymphatics. Subsequently, an intradermal nevus from the area of drainage of the axillary lymph nodes was excised, which showed groups of nevus cells lying within small lymphatic channels. It is postulated that the nevus cells in the lymph node capsule could represent benign metastases from the intradermal nevus.
