Patient's question:
I have a white spot on my glans, next to the urethral opening, about the size of a peanut. It's not visible when erect. What disease is this? I used to have mycoplasma infection.Doctor's answer:
According to your description, it is likely a symptom of vitiligo. Since the symptoms of vitiligo are divided into two types: localized and generalized, this classification is mainly based on the distribution area of the patient's white patches. Localized vitiligo refers to white patches that are more prominent in a specific part of the body, making the affected area clearly visible. However, generalized vitiligo has no regional restrictions and typically affects the entire body. The primary characteristic is the presence of white patches, which appear as circular, dull-colored areas on the surface of the patient's skin. In the early stages, the boundary between the white patches and the surrounding normal skin is unclear, and there may be a slight redness. As the condition progresses, the boundary of the white patches becomes more distinct, and the redness may disappear.
