Which of the following is NOT considered one of the secondary phase lesions associated with Syphilis?

In the context of secondary syphilis, lesions can manifest in various organs and systems, reflecting the systemic nature of the infection. The secondary stage is primarily characterized by mucous membrane lesions, as well as involvement of various organs, including the kidneys and liver. These manifestations are a result of treponemal spread throughout the body.

The Argyll Robertson pupil, on the other hand, is a distinct neurological manifestation associated with tertiary syphilis, specifically indicating involvement of the central nervous system and is characterized by pupils that constrict with accommodation but do not react to light. This neurological effect develops later in the disease course and is not a direct lesion or manifestation of the secondary phase of syphilis. Thus, it does not fit within the classification of secondary phase lesions and is correctly identified as not being one of them.

Understanding these distinctions is crucial, as they reflect the stages of the disease and the types of lesions that are formed as the infection progresses.
