What symptoms do people with hand and foot fungus experience?
Disease description:
My friend is 30 years old this year and recently noticed numerous rice-grain-sized red spots on the body. After visiting the hospital for examination, the diagnosis was tinea manuum and tinea pedis (hand and foot ringworm). I would like to know what symptoms occur in humans with tinea manuum and tinea pedis.

Dr. Liu Wan
Tinea pedis (athlete’s foot) is clinically classified into three main types based on its cutaneous manifestations:
1. Vesicular (papulovesicular) type,
2. Intertriginous (macerated and erosive) type,
3. Hyperkeratotic (squamous, hyperkeratotic) type.
The vesicular type is the most common, characterized primarily by erythema and papules. Vesicles are typically rice-grain-sized and occur predominantly on the palms, soles, and interdigital spaces of the feet.
The intertriginous (macerated and erosive) type mainly affects the interdigital spaces of the toes and fingers, presenting with maceration and whitish discoloration of the skin.
The hyperkeratotic type is marked by thickened, rough, and dry skin—especially on the palms and soles—leading to fissures.
The primary diagnostic method for tinea manuum (hand dermatophytosis) is direct microscopic examination for fungi. A potassium hydroxide (KOH) preparation is first obtained from a skin scraping; fungal culture may be performed subsequently to confirm the diagnosis.
