Patient's question:
Recently, it seems that due to friction from underwear, I have noticed swelling, redness, exudation, and desquamation on my glans. Secondary infection has led to purulent discharge, forming ulcers, accompanied by symptoms of pain. What are the differential diagnoses for balanoposthitis?Doctor's answer:
1. Carefully examine the test: Candidal balanitis (balanoposthitis) can be identified by selecting samples from the inflamed glans or foreskin for microscopic examination or culture, where Candida can be found. Trichomoniasis balanitis can be identified by finding Trichomonas in the discharge.2. Direct microscopy: Scrape off the scales from the affected areas of the glans, coronal sulcus, or foreskin as the specimen for examination. Prepare the specimen with 10% potassium hydroxide or physiological saline for microscopic examination. Numerous oval-shaped spores and pseudohyphae can be observed under the microscope. If a large number of pseudohyphae are found, it indicates that the Candida is in the bloodstream stage.
