What symptom is associated with the vesiculobullous form of athlete's foot caused by Trichophyton mentagrophytes?

• A. Red, scaly patches
• B. Tense vesicles or bullae over the soles
• C. Itchy dry skin
• D. Painful blisters

Answer: (B)

The vesiculobullous form of athlete's foot, which is caused by the fungus Trichophyton mentagrophytes, is characterized primarily by the presence of tense vesicles or bullae, particularly on the soles of the feet. This specific manifestation occurs due to a more severe inflammatory response to the fungal infection, leading to the formation of fluid-filled blisters. These tense vesicles may be located on areas of the feet that are subject to friction, making them a distinguishing feature of this type of infection. In contrast, the other options describe manifestations that are typical of different types of dermatophyte infections or less severe forms of athlete's foot. For example, red, scaly patches and itchy dry skin are more often associated with other forms of tinea pedis, which do not involve the blistering that is specific to the vesiculobullous form. Similarly, painful blisters can occur, but in the context of the question, the distinct feature of tense vesicles is what specifically highlights this variation of athlete's foot, making it the correct answer.
