Which condition is characterized by an overgrowth of skin cells that can cause the nails to appear thickened?

Onychomycosis
Psoriasis
Hangnail
Paronychia

The correct answer is: Psoriasis

The condition characterized by an overgrowth of skin cells that can cause the nails to appear thickened is psoriasis. This autoimmune disorder leads to rapid skin cell turnover, resulting in patches of red, raised skin covered with silvery-white scales. When it affects the nails, it often causes pitting, discoloration, and thickening, making the nails appear distorted or abnormal in texture and thickness. In contrast, onychomycosis refers to a fungal infection of the nails, which can also lead to thickening but is primarily caused by a microorganism rather than an overgrowth of skin cells. A hangnail is simply a small tear in the cuticle or surrounding skin, while paronychia is an infection of the skin around the nail, which can cause swelling and redness, but again, it does not involve the specific overgrowth of skin cells characteristic of psoriasis.
