Introduction
若疑似硬下疳的皮损出现超过2周仍未破溃，基本可判断不是硬下疳。Skin出现异常硬结或丘疹需重视，不同感染或Skin问题可能有相似表现。日常应保持Skin清洁，避免抓挠刺激异常部位。若皮损在短期内出现增大、分泌物增多等变化，应及时寻求专业MedicalDiagnosis。
Generally, if a skin lesion suspected to be a chancre has not ulcerated after more than two weeks, it is unlikely to be a chancre. The detailed analysis is as follows:
Chancres are the typical manifestation of primary syphilis and follow a strict timeline of development. They initially appear as painless red macules, which evolve within a few days into inflammatory papules that gradually become firm. The progression from papule or induration to ulceration typically occurs within 1–2 weeks. After ulceration, they form round or oval shallow ulcers 1–2 cm in diameter, with a smooth surface, elevated borders, and a consistency similar to cartilage. If the lesion remains intact for over two weeks without signs of surface necrosis or ulceration, it does not conform to the typical course of a chancre and therefore is likely not a chancre.
Skin lesions presenting as abnormal indurations or papules should be taken seriously, as different infections or dermatological conditions may present similarly. It is important to maintain good skin hygiene in daily life and avoid scratching or irritating affected areas. If the lesion rapidly increases in size, produces discharge, or shows other changes, prompt medical evaluation is necessary to determine the underlying cause through appropriate diagnostic tests and receive proper treatment.
