Breast carcinoma metastasis to the cheek: a case report.

Breast carcinoma is a common tumor in women, but it rarely metastasizes to the oral region. Furthermore, metastases to the oral region occur mainly to the maxillary and mandibular bone and rarely to soft tissue. We describe a case of breast cancer metastasis to the buccal area. Examination of the right buccal mass of a 66-year-old Japanese woman was suggestive of breast cancer metastasis, and a breast lump was detected. Since receiving hormone-based treatment, the patient has survived more than 5 years and is now in remission. An oral metastatic lesion may be the first sign of breast carcinoma; oral surgeons should be aware of this possibility.

乳腺癌是女性常见的肿瘤，但很少转移至口腔区域。此外，转移至口腔区域主要发生在上颌骨和下颌骨，很少累及软组织。 我们描述了一例乳腺癌转移至颊部的病例。一名66岁日本女性右侧颊部肿物检查提示为乳腺癌转移，并且发现了乳腺肿块。自从接受激素治疗以来，该患者已存活超过5年，目前处于缓解期。 口腔转移性病变可能是乳腺癌的首发症状；口腔外科医生应意识到这种可能性。
