腋窩原発の皮膚アポクリン癌の 1 例

抄録

We report herein on a case of cutaneous apocrine carcinoma, a rare malignant tumor of the skin, arising in the axilla of a 72-year-old female. Aspiration cytology showed tumor cells with abundant cytoplasm and decapitation secretion, arranged in papillary, tubular and solid patterns. Although cytological atypia was weak, the lack of myoepithelial cells and the presence of pair cells suggested malignancy. In this case, it was difficult to determine the presence or absence of malignancy, since the tumor was a well differentiated type (low grade) as shown by the histopathological findings.
