Which statement about Cutaneous Mycoses (superficial) is true?

Which statement about Cutaneous Mycoses (superficial) is true?

• A. They always invade deeper tissues
• B. They require culture to observe yeast
• C. They show superficial scaling and rarely invade deeper tissues
• D. They do not form hyphae

Answer: (C)

Superficial cutaneous fungal infections stay confined to the outermost skin layers and other keratinized tissues like hair shafts and nails. They cause scaling and itch but typically do not penetrate into deeper tissues. That limited, epidermis-centric behavior is what sets them apart from deeper fungal infections and explains why symptoms are mainly surface-based rather than systemic or invasive. You can often see fungal elements directly on skin scrapings with simple microscopy (like a KOH prep), and culture is not required just to observe those elements—it’s mainly used if you need to identify the exact species. The idea that they require culture to observe yeast is not accurate, and these infections can involve hyphae in the appropriate tissues (dermatophytes) or yeast forms in others (like Malassezia), so saying they do not form hyphae isn’t universally true. The key truth is the superficial nature with surface-scale symptoms and rare deeper invasion.
