卵巢畸胎瘤是卵巢生殖细胞肿瘤中最常见的良性肿瘤,卵巢囊性畸胎瘤又称成熟性囊性畸胎瘤,是常见的畸胎瘤类型。卵巢畸胎瘤的内容物可由2~3个胚层的组织形成,含有皮肤及其附件、毛发、牙齿、神经、脂肪、骨骼等。虽然这些成分在理论上可...卵巢畸胎瘤是卵巢生殖细胞肿瘤中最常见的良性肿瘤,卵巢囊性畸胎瘤又称成熟性囊性畸胎瘤,是常见的畸胎瘤类型。卵巢畸胎瘤的内容物可由2~3个胚层的组织形成,含有皮肤及其附件、毛发、牙齿、神经、脂肪、骨骼等。虽然这些成分在理论上可以来自任何胚层,但实际上,完整地包含各种组织的畸胎瘤较为罕见。本文报道了一例合并美尼尔氏综合征、高血压、肥胖、II型糖尿病的女性患者,经过超声影像学提示卵巢畸胎瘤并手术治疗后发现畸胎瘤中含有皮肤、毛发、骨骼、牙齿、甲状腺组织的特殊病例。关于您提到的具体病例,即合并美尼尔氏综合征、高血压、肥胖、II型糖尿病的女性患者,超声影像学提示卵巢畸胎瘤,并在手术治疗后发现畸胎瘤中含有皮肤、毛发、骨骼、牙齿、甲状腺组织,这在临床诊疗中确实是一种罕见的病例。Ovarian teratoma is the most common benign tumor among ovarian germ cell tumors, and ovarian cystic teratoma, also known as mature cystic teratoma, is the most common type of teratoma. The contents of ovarian teratomas can be formed by tissues from two or three germ layers, including skin and its appendages, hair, teeth, nerves, fat, bones, etc. Although theoretically, these components can come from any germ layer, teratomas that fully contain various tissues are rare in practice. This article reports a special case of a female patient with Meniere’s syndrome, hypertension, obesity, and type II diabetes. Ultrasound imaging suggested an ovarian teratoma, and after surgical treatment, the teratoma was found to contain skin, hair, bones, teeth, and thyroid tissue. Regarding the specific case you mentioned, a female patient with Meniere’s syndrome, hypertension, obesity, and type II diabetes, in which ultrasound imaging suggested an ovarian teratoma, and post-surgery revealed the presence of skin, hair, bones, teeth, and thyroid tissue, this indeed represents a rare case in clinical practice.展开更多
