The treatment of psoriasis has undergone a revolution with the advent of biologic therapies including infliximab, etanercept, adalimumab, efalizumab, golimumab, certolizumab, alefacept, secukinumab, abatacept, and ustekinumab. These medications are designed to target specific components of the immune system and are a major technological advancement...
Sunlight- and indoor ultraviolet (UV)-induced tanning is a common behavior, especially among adolescents, young adults, and individuals who have lighter skin. Excessive sun exposure is associated with several health risks, including the acceleration of skin aging and the promotion of skin cancers. Several health benefits of UV exposure include vita...
Solar urticaria is an uncommon condition characterized by erythema and whealing shortly after exposure to ultraviolet (UV) and/or visible light. We report a 25-year-old woman with an erythematous, edematous, pruritic reaction minutes after sun exposure while she was taking terbinafine for onychomycosis. Phototesting revealed a UVB-sensitive urticar...
Squamous cell carcinoma (SCC) developing in chronic hidradenitis suppurativa (HS) is rare, but failing to recognize the condition may have significant consequences. Dermatologists must be aware of the potential for malignant transformation and should have a low threshold for biopsy when clinical presentation is atypical. Herein we describe a 64-yea...
We report two unique cases of patients with Darier disease and hidradenitis suppurativa. Although it is unknown whether there is a connection between the two diseases, it is possible that an interaction between sarcoendoplasmic reticulum calcium transport ATPase and Notch homolog 1, translocation-associated (Drosophila) caused both diseases in thes...
Excessive sun exposure is known to be the leading cause of skin cancer. The direct cellular damage inflicted by the ultraviolet (UV) radiation from the sun results in premature aging, DNA damage, and mutations that ultimately lead to skin cancer. Sunscreens are highly recommended to protect against UV radiation. However, little research has been co...
Acne vulgaris is a widely prevalent chronic skin disease. Although multiple treatments are available, acne can sometimes be refractory to these treatments. The use of alternative medical therapies has increased within dermatology and for acne. This case report describes a patient in whom the addition of cedarwood oil was helpful in controlling acne...
An 84-year-old man presented with an enlarging bluish, painless subcutaneous nodule on the glabella. The lesion had been excised 4 years prior and was diagnosed as chondroid syringoma, but had gradually regrown. The recurrent lesion was treated by surgical re-excision. Histopathological examination was again consistent with chondroid syringoma, and...
