肌上皮癌是一种典型地出现在腮腺中的肿瘤,鼻咽部,鼻旁窦,和头部和颈部的鼻腔。它很少出现在其他器官或软组织中,泌尿生殖器官的受累明显罕见。我们描述了一个21岁男性的案例,出现恶心,减肥,3个月以上耻骨上疼痛恶化,发现膀胱圆顶有一个大肿块。最终进行部分膀胱切除术,显示膀胱肌上皮癌。患者在四年内没有疾病,不需要全身治疗。
Myoepithelial carcinoma is a neoplasm that classically arises in the parotid glands, nasopharynx, paranasal sinus, and nasal cavity of the head and neck. It rarely arises in other organs or soft tissues and involvement of genitourinary organs is distinctly rare. We describe a case of a 21-year-old male, presenting with nausea, weight loss, and worsening suprapubic pain over 3 months, found to have a large mass at the dome of the bladder. Partial cystectomy was ultimately performed revealing myoepithelial carcinoma of the bladder. The patient is free of disease at four years without the need for systemic therapy.
