Ectopic breast tissue (EBT) predominantly seen along the primitive embryonic milk lines that extend from axilla to groin. Axillary breast tissue is one of the common variant of EBT seen in 2% to 6% of women. Phyllodes tumour in EBT is uncommon. The various cystic, inflammatory and neoplastic lesions may occur in EBT similar to breast counterpart. Therefore, EBT should be carefully investigated as it may affect the management of the patient. We report two cases (axillary phyllodes tumour and axillary fibroadenoma) of axillary EBT diagnosed on cytology.
异位乳腺组织（EBT）主要见于从腋窝延伸至腹股沟的原始胚胎乳线。腋窝乳腺组织是EBT的常见变体之一，在2%至6%的女性中可见。EBT中的叶状肿瘤并不常见。EBT中可能出现各种囊性、炎症性和肿瘤性病变，与乳腺对应病变相似。因此，应对EBT进行仔细检查，因为它可能会影响患者的治疗。我们报告了两例经细胞学诊断的腋窝EBT病例（腋窝叶状肿瘤和腋窝纤维腺瘤）。
