Photodermatoses are a group of heterogeneous disorders with diverse clinical manifestations and complex aetiology. They can be classified into five general categories including (1) photodermatoses which are secondary to exogenous agents, such as phototoxic and photoallergic reactions, (2) photoexacerbated dermatoses, (3) photodermatoses which are idiopathic such as polymorphic light eruption (P...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-205974 DESCRIPTION A middle aged Southeast-Asian man, recently diagnosed with chronic myeloid leukaemia (Philadelphia positive on FISH), was started on cytoreductive therapy with hydroxyurea due to high leucocyte count (130 000/mL). The patient had no history o...

Twenty patients with photodermatoses [actinic prurigo (n = 6), hydroa vacciniforme (n = 4), idiopathic solar urticaria (n = 1), amiodarone-induced photosensitivity (n = 1) and a range of cutaneous porphyrias (n = 8)] were treated with a 'hardening' course of narrow-band ultraviolet B (TL-01) phototherapy in springtime. The response to phototherapy was monitored subjectively, by interviewing pat...

Actinic prurigo (AP) is a rare acquired idiopathic photodermatosis, reported most often in American Indians, but also in Caucasian and Asian populations. The skin lesions in AP predominantly affect exposed sites but may involve covered areas, and often result in postinflammatory scarring. The diagnosis of AP can be difficult and relies on a combination of history, clinical experience and invest...

Prurigo nodularis is an intensely pruritic dermatosis characterized by lichenified and excoriated papules and nodules. The course of prurigo nodularis is often chronic, and some patients respond very poorly to the standard therapeutic modalities. Because the pathogenesis of this disease remains obscure, the treatment of prurigo nodularis can be disappointing and frustrating for both the patient...

INTRODUCTION We previously reported a cohort of elderly patients with concurrent development of debilitating prurigo nodularis, extreme and disabling pruritus with or without eczematous dermatitis, and keratoacanthomas in the presence of actinic damage. This report is a long-term follow through on patients who were successfully transitioned from cyclosporine, acitretin, and topical 5-fluorourac...

Prurigo is a condition of nodular cutaneous lesions that itch intensely. Prurigo lesions are divided into acute, subacute and chronic forms that itch intensely. Subacute prurigo (SP) clinically presents as excoriated papules mostly in a symmetrical distribution on the extensor surfaces of the extremities, neck, lower trunk, and buttocks. It tends to occur in middle-aged patients, especially in ...
