In a large cross-sectional study of more than 6,000 adults in the United States, the overall prevalence of psoriasis was estimated at 1.9 percent. Although prevalence was lower among individuals with darker Fitzpatrick skin types, these patients experienced greater disease severity and quality-of-life burden. This disparity may reflect delayed recognition,...]]></description><link>https://www.skintoneconditions.com/post/psoriasis</link><guid isPermaLink="false">698cf7d8e46957565bf2bc6d</guid><pubDate>Wed, 11 Feb 2026 21:43:17 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/114ea4_f66aa0ad00414ff5bee06b27e1fa645d~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>UAMS Dermatology Students</dc:creator></item><item><title><![CDATA[Lichen Planus]]></title><description><![CDATA[Lichen planus (LP) is a chronic, inflammatory dermatosis characterized by T cells targeting basal keratinocytes because of dysregulated cell-mediated immunity, with associations including viral infections, medications, contact allergens, and autoimmune conditions. In individuals with darker skin tones, hypertrophic, pigmentosus, and actinic variants of lichen planus are observed more frequently, suggesting that environmental and pigmentary factors may influence disease expression.  Lichen...]]></description><link>https://www.skintoneconditions.com/post/lichen-planus</link><guid isPermaLink="false">698cf79f31ffa9c2435ff661</guid><pubDate>Wed, 11 Feb 2026 21:42:24 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/114ea4_24013015558e47b182db19e4e31b1377~mv2.jpg/v1/fit/w_474,h_303,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>UAMS Dermatology Students</dc:creator></item><item><title><![CDATA[Seborrheic Dermatitis]]></title><description><![CDATA[Seborrheic dermatitis (SD) is a chronic inflammatory dermatosis affecting sebaceous-rich areas and is among the five most common dermatologic diagnoses in Black individuals. In the general population, SD affects approximately 5 percent of individuals; however, prevalence is higher among African Americans, estimated at 6.5 percent.

CD is broadly classified into  irritant contact dermatitis (ICD)  and  allergic contact dermatitis (ACD ) . ICD results from direct chemical injury to the skin followed by the release of inflammatory mediators from epidermal cells. ACD is a type IV delayed hypersensitivity reaction mediated by T cells. Overall, CD is more frequently reported in women, likely due to higher exposure to jewelry,...]]></description><link>https://www.skintoneconditions.com/post/contact-dermatitis</link><guid isPermaLink="false">698cf71e5ce248ef4489cdef</guid><pubDate>Wed, 11 Feb 2026 21:40:17 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/114ea4_d9f45da4fe764b7c97876af8cec03419~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>UAMS Dermatology Students</dc:creator></item><item><title><![CDATA[Molluscum Contagiosum]]></title><description><![CDATA[Molluscum contagiosum is a common cutaneous viral infection caused by a DNA poxvirus and is frequently encountered in children and adolescents. Incidence increases during adolescence due to closer skin-to-skin contact, participation in athletics, shared equipment, and shaving practices. The virus infects epidermal keratinocytes, leading to the formation of characteristic dome-shaped papules.

The etiology of atopic dermatitis is complex and multifactorial. Although the exact mechanism is unknown, it is believed that AD arises from an interplay of epidermal barrier dysfunction, immune dysregulation and microbiome alterations. Additionally, genetic predispositions, such as loss-of-function mutations in the filaggrin gene, may set the stage for the immune-driven...]]></description><link>https://www.skintoneconditions.com/post/dermatology-insights-skin-conditions-by-color-presentation</link><guid isPermaLink="false">68e7ff41a4a8e4d1e884d72e</guid><pubDate>Thu, 09 Oct 2025 18:30:25 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/114ea4_0fa563f740e241b09bce9bcb410df45c~mv2.jpg/v1/fit/w_474,h_305,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>UAMS Dermatology Students</dc:creator></item><item><title><![CDATA[Infantile Hemangiomas]]></title><description><![CDATA[Infantile hemangiomas are common benign vascular tumors of infancy that between 4-5% of infants, making it the most common infantile tumor. It arises due to an abnormal proliferation of endothelial cells and vascular networks, likely driven by factors such as hypoxia, aberrant stem cell activation, and dysregulated signaling pathways. The progression of infantile hemangiomas is classically biphasic.

Transmission is most often peripartum, though a minority, < 5–10%, of cases may represent in utero (congenital) infection with transplacental spread.   After exposure, the virus replicates and disseminates manifesting in one of three overlapping syndromes: SEM disease (skin, eye, mouth), CNS...]]></description><link>https://www.skintoneconditions.com/post/understanding-skin-conditions-across-diverse-skin-tones</link><guid isPermaLink="false">68e7ff28a5a8e77456def7f5</guid><pubDate>Thu, 09 Oct 2025 18:30:00 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/114ea4_86e4cd28e4644eacbfe90c2b0148ad77~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>UAMS Dermatology Students</dc:creator></item></channel></rss>
