Actinic prurigo is a rare disease occurring mainly in individuals of American Indian origin and those living in high altitudes. Skin lesions consist of pruritic popular or nodular excoriated lesions mainly affecting exposed skin but covered skin is also involved in up to 50% of patients. This is the first case report of an Iranian patient. This 19-year-old female had pruritic popular and ...

the clinical and phenotypic features of two siblings (a 12 years old girl and her 7 year old brother) with cockayne syndrome are described. the main problems were mild to moderate mental retardation, dwarfism, clumsy gait, photosensitive skin lesions and progeroid (senile like) appearance. brain ct - scans revealed symmetrical, well defined areas of calcification mainly located at lenticular nu...

Photosensitivity and induction of skin lesions following UV radiation is a common problem of patients with cutaneous and systemic forms of lupus erythematosus. The detrimental effect of UV radiation to patients with lupus erythematosus was already recognized in the last century. Skin lesions can now be provoked under standardized conditions allowing the diagnosis and classification of patients ...

BACKGROUND The pathogenic mechanisms of UV-induced skin lesions of lupus erythematosus (LE) are unknown. In a recent study of pathogenic mechanisms of polymorphic light eruption (PLE), significantly more Langerhans cells (LCs) persisted in the epidermis after UVB overexposure than in healthy individuals. Interestingly, the same phenomenon was observed in one subacute cutaneous lupus erythematos...

Gabapentin usually has a good safety profile with adequate tolerance. The incidence of adverse reactions in skin, hair and mucosa due to gabapentin is low. Here, we present a case of lichenoid photosensitive eruption due to application of gabapentin in exposed areas. A lichenoid eruption with skin lesions that are widespread distributed requires a drug history as well as stopping the consumptio...

skin lesions were found in two 3–4-year-old holstein cows in a dairy farm in shiraz. lesions were distributed mostly around the neck, forelimbs, hindlimbs, and bilateral of midline portion and varied from nodule-like structure to patch with extensive accumulation of crust. skin scraping samples were taken from each animal and direct smears were prepared, stained with giemsa and observed under a...

Dermatomyositis (DM) is an idiopathic inflammatory process characterized by proximal muscle weakness and cutaneous lesions, such as the Gottron's sign, heliotrope rash, and erythematous photosensitive rash. Administration of systemic agents for the treatment of underlying systemic diseases leads to remission of the cutaneous lesions in many cases. However, cutaneous lesions may remain refractor...

The cutaneous diseases associated with progesterone are autoimmune progesterone dermatitis, erythema multiforme-like eruption, drug-induced progesterone dermatitis and solar urticaria. Estrogen and progesterone are widely used in oral contraceptives and hormone replacement therapies, and they are rarely known to cause a photosensitive reaction. The mechanism of contraceptive-induced photosensit...

Investigators from multinational institutions hypothesized that disruption of CHD2, which encodes chromodomain helicase DNA-binding protein 2, would be associated with common forms of photosensitive epilepsy or photosensitivity manifesting as a photoparoxysmal response alone.
