Napkin Psoriasis (Severe Diaper Rash)
Infants may experience a skin condition that closely resembles severe diaper rash, but in fact, it is known as napkin psoriasis. This condition typically affects infants aged between two and eight months. The lesions associated with napkin psoriasis appear as small red papules that are covered with white or silver scales. Although the rash primarily develops in the diaper area, it can also spread to the limbs or torso. Experts suggest that napkin psoriasis is caused by similar factors that contribute to diaper rash, such as infections, sensitive skin, and irritation caused by stool and urine.
Plaque and Fissured Tongue in Psoriasis
Psoriasis, a chronic skin condition, can also affect the mouth, although it is relatively rare. This oral manifestation of psoriasis may not show any symptoms, but in some cases, it can present as white or yellow-gray plaques caused by the buildup of pus and dead cells. Additionally, individuals with psoriasis may experience a condition known as fissured tongue, where the tongue develops cracks of varying sizes, shapes, and depths. Despite its appearance, fissured tongue is usually painless. The exact cause of this symptom is still uncertain, but researchers have observed a higher likelihood of individuals with psoriasis developing periodontal disease, which can result in swollen or bleeding gums.
