prurigo pigmentosa

Isa An, Derya Ucmak, Ibrahim Ibiloglu, Vasfiye Demir, Sedat Akdeniz
Prurigo pigmentosa (PP) is a rare inflammatory skin disease. Neutrophil-mediated inflammation is considered to be responsible for the etiopathogenesis of PP. We consider that colchicine may be an effective agent in the treatment of PP since it exerts an antiinflammatory effect by inhibiting neutrophil chemotaxis. Further studies are required to verify whether colchicine is an effective treatment option for PP.

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

Prurigo pigmentosa is a rare inflammatory skin disease of unknown origin, mostly described in the ethnic Japanese population. Etiology and pathogenesis are not completely known. Tetracyclines or dapsone are the therapy of choice. A 17-year-old Swiss patient with Turkish parents presented with pruritic rash on the neck and trunk, which started after a diet. Under therapy with doxycycline over 5 weeks, complete healing with slight reticular hyperpigmentation was observed.

Prurigo pigmentosa is a rare inflammatory dermatosis that primarily affects adolescents and young adults. Even though it is most commonly seen in Japanese women, other countries have reported cases with increasing frequency. It is characterized by erythematous papules and macules on the trunk, neck and chest that resolve leaving a reticulate hyperpigmentation. Some endogenous factors related with ketosis like fasting, diet, diabetes, pregnancy and exogenous agents like chrome, nickel, para-amino compounds have been accused of playing a role in etiology...

Over the last few years, dermoscopy has been shown to be a useful tool in assisting the noninvasive diagnosis of various general dermatological disorders. In this article, we sought to provide an up-to-date practical overview on the use of dermoscopy in general dermatology by analysing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical presentation, i.e. dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides and subacute cutaneous lupus erythematosus), papulosquamous/papulokeratotic dermatoses (lichen planus, pityriasis rosea, papulosquamous sarcoidosis, guttate psoriasis, pityriasis lichenoides chronica, classical pityriasis rubra pilaris, porokeratosis, lymphomatoid papulosis, papulosquamous chronic GVHD, parakeratosis variegata, Grover disease, Darier disease and BRAF-inhibitor-induced acantholytic dyskeratosis), facial inflammatory skin diseases (rosacea, seborrheic dermatitis, discoid lupus erythematosus, sarcoidosis, cutaneous leishmaniasis, lupus vulgaris, granuloma faciale and demodicidosis), acquired keratodermas (chronic hand eczema, palmar psoriasis, keratoderma due to mycosis fungoides, keratoderma resulting from pityriasis rubra pilaris, tinea manuum, palmar lichen planus and aquagenic palmar keratoderma), sclero-atrophic dermatoses (necrobiosis lipoidica, morphea and cutaneous lichen sclerosus), hypopigmented macular diseases (extragenital guttate lichen sclerosus, achromic pityriasis versicolor, guttate vitiligo, idiopathic guttate hypomelanosis, progressive macular hypomelanosis and postinflammatory hypopigmentations), hyperpigmented maculopapular diseases (pityriasis versicolor, lichen planus pigmentosus, Gougerot-Carteaud syndrome, Dowling-Degos disease, erythema ab igne, macular amyloidosis, lichen amyloidosus, friction melanosis, terra firma-forme dermatosis, urticaria pigmentosa and telangiectasia macularis eruptiva perstans), itchy papulonodular dermatoses (hypertrophic lichen planus, prurigo nodularis, nodular scabies and acquired perforating dermatosis), erythrodermas (due to psoriasis, atopic dermatitis, mycosis fungoides, pityriasis rubra pilaris and scabies), noninfectious balanitis (Zoon's plasma cell balanitis, psoriatic balanitis, seborrheic dermatitis and non-specific balanitis) and erythroplasia of Queyrat, inflammatory cicatricial alopecias (scalp discoid lupus erythematosus, lichen planopilaris, frontal fibrosing alopecia and folliculitis decalvans), nonscarring alopecias (alopecia areata, trichotillomania, androgenetic alopecia and telogen effluvium) and scaling disorders of the scalp (tinea capitis, scalp psoriasis, seborrheic dermatitis and pityriasis amiantacea)...

Prurigo pigmentosa (PP) is a rare inflammatory disease of the skin of uncertain etiology first reported in Japan. It is typified by recurrent eruptions of itching urticarial macules, papules, vesicopapules, and plaques with a reticular arrangement that quickly resolve leaving a net-like pigmentation. The disease presents specific histopathological features. Herein, 3 cases of PP in Brazilians with no Japanese ancestry are reported and a revision of all previous English-language case reports indexed on PubMed is provided...

Prurigo pigmentosa, also referred to as Nagashima's disease, is a rare inflammatory skin condition of unknown etiology. It typically presents as pruritic erythematous papules, papulovesicles, and vesicles appearing in a reticular pattern on the back, chest, or neck. The histological features of prurigo pigmentosa vary according to the stage of the disease. Early-stage disease is characterized by a superficial perivascular infiltrate of neutrophils; spongiosis and necrotic keratinocytes commonly appear in later stages...

We present a 21-year-old Italian girl with an 8-year history of missed diagnosed prurigo pigmentosa (PP) successfully treated with short monotherapy with minocycline. PP is an inflammatory disease characterized by recurrent pruritic erythematous papules followed by reticular hyperpigmentation usually located on the trunk. About 300 cases of PP have been described mainly in Japan, whereas only few cases have been reported in Italy. This report shows that minocycline is rapidly effective probably through its ability to scavenge reactive oxygen species and to inhibit the chemotaxis and neutrophil function...

Prurigo pigmentosa (PP) is a rare inflammatory dermatosis originally reported in Japan. Since then, most reports have originated from Asia, and to a lesser extent from Europe. Although the pathogenesis remains unclear, it is now established that PP is linked to ketoacidotic states. Four patients diagnosed with PP were identified from the dermatopathology database at the American University of Beirut Medical Center between January 2009 and December 2013. Clinicopathologic findings in the 4 patients were similar to those previously reported in the literature...

Prurigo pigmentosa (PP) is an inflammatory skin disease of unknown origin. The skin lesions in PP are symmetrically distributed on the back, chest, and neck. Pruritus is a prominent feature in many cases. We report on a 13-year-old girl with lesions typical of PP in a segmental arrangement on her left chest. A segmental distribution of PP has not been previously reported.

Prurigo pigmentosa (PP) is a rare inflammatory dermatosis of unknown cause characterized by a predominantly truncal eruption of pruritic erythematous papules in a reticular pattern, resolving with hyperpigmentation. PP is twice as common in girls and women, and the mean age at onset is 25 years. Diagnosis of PP is challenging and is aided by characteristic histopathologic findings. We report a case of PP in a 17-year-old white boy. The eruption arose during strict adherence to a ketogenic diet.
