前列腺小细胞癌罕见,文献仅报道15例,其中8例肿瘤分泌促肾上腺皮质激素,1例肿瘤分泌抗利尿激素。关于小细胞癌的组织发生仍有争议。鉴于它与类癌、燕麦细胞癌的形态学相似,对神经内分泌细胞的免疫组化实验呈阳性反应,超微结构可见一些致密核心颗粒,故推测它来源于神经嵴。然而,小细胞癌与普通前列腺腺癌的联系又表明它可能来源于具有神经内分
Small cell carcinoma of the prostate is rare. Only 15 cases have been reported in the literature. Among them, 8 cases of tumors secrete adrenocorticotropic hormone and 1 case of tumor secretes antidiuretic hormone. The organization of small cell carcinoma remains controversial. In view of its morphological similarity to carcinoid and oat cell carcinoma, the immunohistochemical experiment of neuroendocrine cells showed a positive reaction. The ultrastructure showed some dense core particles, so it is presumed to be derived from neural crest. However, the link between small cell carcinoma and normal prostate adenocarcinoma also suggests that it may have a
