近年来尽管在研究合成甲状旁腺激素及甲状腺的正常腺体与腺瘤和增生腺体细胞之间DNA的差异等方面有所进展,但甲状旁腺机能亢进的病因仍不清楚。对甲旁亢的组织学分类仍有争论,因此名词众多。如:单个腺体病变,多个腺体病变、腺瘤、增生和腺瘤样增生等。一般认为原发性甲旁亢以单发性腺瘤为最常见,但也有人持异议。有经验的病理学者在鉴别单个腺瘤与多个腺体增生时也会遇到困难,但外科医师在术中必须做出鉴别。我们在术中用密度测定来进行鉴别。本法依据正常成人甲状旁腺细胞内外含有多量脂肪,异常腺体不论是腺瘤样变或增生,脂肪量减少,所以异常腺体的密度比正常腺体高,手术时,密度可用简单的漂浮法来测定。
In recent years, despite advances in the study of the synthesis of parathyroid hormone and normal glands of the thyroid gland and adenomas and hyperplastic glandular cells, advances have been made, but the cause of hyperparathyroidism remains unclear. There is still controversy over the histological classification of hyperparathyroidism, so there are many terms. Such as: single gland lesions, multiple glandular lesions, adenomas, hyperplasia and adenomatous hyperplasia. It is generally believed that primary hyperparathyroidism is the most common single adenoma, but some people disagree. Experienced pathologists will also encounter difficulties in identifying single adenomas and multiple glandular hyperplasias, but surgeons must identify during surgery. We use the density measurement to identify during surgery. This method is based on normal human adult parathyroid cells containing a large amount of fat inside and outside, abnormal glands, whether adenomatous changes or hyperplasia, reduced fat, so the abnormal gland density is higher than the normal glands, surgery, the density can be a simple floating method To determine.
