A Case of Alopecia Neoplastica from Breast Cancer / 대한피부과학회지

ABSTRACT

We report a case of alopecia neoplastica in a 54-year-old woman, who presented with a 2 month history of a solitary 2X2 cm sized, erythematous hairless plaque on the vertex. Histological findings showed an extensive infiltration of tumor cells in the dermis, resulting in loss of the pilosebaceous structure. Tumor cells infiltrated in sheets or cords of cells, sometimes demonstrating glandular structures, and tumor cells formed small groups or single rows between thickened collagen bundles; the characteristic features of alopecia neoplastica.
