Methods The ultrastructural pathological changes of syphilitic chancre were examined with transmission electron microscopy.

Hard chancre showed that epidermis might be absent in the center of the disease focuses and a diffuse mixed inflammatory infiltration was present at upper and middle dermis or the whole dermis as well as the endoangiitis in the dermis.

硬下疳病变中央部表皮缺损，真皮中上部或全层显示弥漫性混合性炎细胞浸润和明显血管内膜炎。

Conclusion The fundamental pathologic changes of hard chancre and secondary syphilis are a subacute inflamation caused by pallidula spirochaeta, and those of nodular tertiary syphilis epithelioid cell granuloma.

结论硬下疳和二期梅毒基本病理改变为梅毒性亚急性炎症，结节型三期梅毒为上皮样细胞肉芽肿。

Results Phase I syphilis manifests hard chancre. Phase II syphilis manifests rash which are complicated.

结果I期梅毒皮疹以硬下疳为主，Ⅱ期梅毒皮疹复杂。

Results In these 162 cases of hard chancre, misdiagnosis occurred to 48 cases, accounting for 29.6%.

结果162例硬下疳患者中，48例曾发生误诊，误诊率为296%。

Objective To explore misdiagnosis of hard chancre and its contributing factors.
