甲状腺癌是较常见的恶性肿瘤。但发病率远较其它癌低,约占所有恶性肿瘤的1～1.3%,占癌症死亡病例的0.4%。甲状腺癌早期常与良性甲状腺瘤,慢性甲状腺炎难以区别,因此,临床上易被忽略。我院将3例甲状腺癌分别误诊为甲状腺囊肿及畸胎瘤。例1:女,36岁。左颈部长包块两月多。2月前无意中发现左颈部有一包块,如乒乒球大小,几天后逐渐长大。1987年11月12日门诊以左颈部甲状腺囊肿收入外一科,于11月26日行甲状腺包块切除术,术中见左甲状腺包块约4×5×5 cm,包膜完整,表面光滑,与周围组织无粘连,切面质韧,有1～2 cm 大小不等的囊腔,似有软骨样组织,病人于12月4日以甲状腺囊肿治愈出院。手术标本12月3日才送检,12月7日病理诊断左甲状腺滤泡性腺癌。
Thyroid cancer is a more common malignancy. However, the incidence rate is far lower than other cancers, accounting for about 1 to 1.3% of all malignant tumors and 0.4% of cancer deaths. Early thyroid cancer is often indistinguishable from benign thyroid tumors and chronic thyroiditis. Therefore, it is clinically overlooked. Our hospital misdiagnosed 3 cases of thyroid cancer as thyroid cysts and teratomas. Example 1: Female, 36 years old. The left neck is long for more than two months. Before 2 months, I found a mass in the left neck, such as the size of a ping-pong ball, which gradually grew after a few days. On November 12, 1987, the outpatient department received a thyroid cyst from the left neck and received a thyroidectomy on November 26th. During the operation, the left thyroid mass was approximately 4×5×5 cm, and the capsule was completely covered. Smooth, with no adhesion to the surrounding tissue, cut surface toughness, 1 ~ 2 cm in size ranging from the cyst cavity, there seems to be cartilage-like tissue, the patient was cured and discharged from the thyroid cyst on December 4. Surgical specimens were examined on December 3, and pathological diagnosis of left thyroid follicular adenocarcinoma was performed on December 7.
