Adenoid cystic carcinoma is a rare neoplasm that originates from secretory glands, most commonly from the salivary glands. We present a 76 year-old white man with a history of adenoid cystic carcinoma from the base of the tongue diagnosed 15 years prior to the development of the metastatic lesion on his mid-posterior scalp. The present case represents the second reported instance of an extracutaneous adenoid cystic carcinoma metastasizing to the scalp. Differentiating between a primary cutaneous adenoid cystic carcinoma and an extracutaneous adenoid cystic carcinoma metastasizing to cutaneous structures is crucial in determining prognosis and management.
腺样囊性癌是一种罕见的肿瘤，起源于分泌腺，最常见于唾液腺。我们报告一例76岁白人男性，有舌根腺样囊性癌病史，在其头皮中后部出现转移灶15年前被诊断。本病例是第二例报道的皮肤外腺样囊性癌转移至头皮的病例。区分原发性皮肤腺样囊性癌和转移至皮肤结构的皮肤外腺样囊性癌对于确定预后和治疗至关重要。
