Acinic cell carcinoma (ACC) is a malignant epithelial neoplasm that commonly occurs in the parotid gland. It is known to have a high recurrence rate and the potential to metastasize to the lung or cervical lymph nodes. However, few cases of ACC with bone metastasis have been reported in the medical literature.
The clinical significance of this case report lies in the unique site of occurrence of the metastasis: To the best of our knowledge, this report is the only literature documenting ACC arising in a shoulder mass.
Unusual presentations of uncommon malignancies can present diagnostic challenges for both surgeons and histopathologists. It is important to be aware of these rare occurrences in order to provide the best possible treatment for patients.
腺泡细胞癌（ACC）是一种常见于腮腺的恶性上皮性肿瘤。已知其具有高复发率以及转移至肺部或颈部淋巴结的可能性。然而，医学文献中报道的ACC发生骨转移的病例很少。
本病例报告的临床意义在于转移发生的独特部位：据我们所知，本报告是唯一记录肩部肿块中发生ACC的文献。
罕见恶性肿瘤的不寻常表现可能给外科医生和组织病理学家带来诊断挑战。了解这些罕见情况对于为患者提供最佳治疗非常重要。
