Prurigo pigmentosa is a recurrent dermatosis with severe pruritus and several peculiar clinical features. Its exact etiology and pathogenesis are unclear. The aim of this study was to investigate the clinical features and chronological changes in the histopathology of prurigo pigmentosa in Korean patients and to assess the etiology of this condition. We reviewed the medical records, clinical ph...

Most of the reported cases have been from Japan; however, here we report on several cases from Taiwan. METHODS This was a single hospital-based retrospective study conducted in a tertiary medical center in Southern Taiwan, recruiting ...

Actinic prurigo is a pruritic sun-induced dermatosis classified among the immunologically mediated photodermatoses. The disease is a well-known entity among Native Americans and in Central and South America, however rare in Caucasians with only a few reports from Australia, Britain and France. We report the first case of actinic prurigo in a Scandinavian patient, responding favorably to systemi...

Epidermolysis bullosa pruriginosa (EBP; OMIM #604129) is an unusual variant of autosomal dominant (or occasionally recessive) dystrophic epidermolysis bullosa (DEB) in which intense itching and scratching impacts upon the phenotype (1, 2). Although trauma-induced blistering often occurs, and toenail dystrophy is almost universal, the skin lesions can often resemble nodular prurigo, lichen simpl...

A 21-year-old Chinese man presented with four years' history of recurrent itchy erythematous papules and reticulated hyperpigmentation over the upper back and chest wall. The diagnosis of prurigo pigmentosa was made. Treatment with oral doxycycline resulted in reduction of pruritus and no emergence of new lesions. Clinical features, histological features and treatment of prurigo pigmentosa will...

Thalidomide is a beneficial agent for treating a variety of refractory dermatologic disorders including erythema nodosom leprosum, lupus erythematosus, prurigo nodularis, actinic prurigo, pyoderma gangrenosum and aphthous stomatitis. Two thalidomide analogues, lenalidomide and CC-4047, are considerably more potent with decreased side effects when compared to thalidomide. They are currently unde...

Prurigo pigmentosa is a distinctive inflammatory disease first described by the Japanese dermatologist Masaji Nagashima in 1971. It is typified by recurrent, pruritic erythematous macules, papules and papulovesicles that resolve leaving behind netlike pigmentation. The disease is rarely diagnosed outside Japan, because clinicians outside Japan are not well conversant with the criteria for its d...

Prurigo nodularis of Hyde is a skin disorder characterized by pruritic excoriated nodules. Improvement in pruritus and decrease in nodules was demonstrated in patients treated with oral thalidomide 200-400 mg daily. We report a case of a 52 year old woman with a history of widespread, persistent, and intensely pruritic lesions on all extremities and a histological diagnosis of "prurigo nodulari...

Prurigo nodularis is a pruritic dermatosis of unknown origin. Human T-cell lymphotropic virus type 1 (HTLV-1) causes adult T-cell leukaemia/lymphoma. HTLV-1 is not considered to be a cause of prurigo nodularis. A 52-year-old black man, from the French West Indies, who had had prurigo nodularis for 12 years, presented with a distinct micropapular eruption with the typical pathological picture of...
