INTRODUCTION: Mastocytosis, a heterogeneous group of disorders, is characterized by an abnormal increase in the number of mast cells that is limited to the skin (cutaneous mastocytosis), involving extracutaneous tissues (systemic mastocytosis), or presenting as solid tumours (mastocytoma and mast cell sarcoma). Recent studies estimate that 1 in 10,000 people are diagnosed with mastocytosis. Although prompt diagnosis and appropriate management are crucial, little is known about the natural history and currently there are no established management guidelines...

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...

Cutaneous mastocytosis is defined by the presence of mast cells within the skin in the absence of other criteria for the diagnosis of systemic mastocytosis. Mast cells are characterized by an abundant granular cytoplasm and a round to oval or spindle-shaped nuclei. The presence of mast cells with bilobed and multilobed nuclei in cutaneous mastocytosis is a rare phenomenon and has been rarely reported in the literature. To our knowledge, there are only 4 reported cases of cutaneous mastocytosis with atypical mast cells...

BACKGROUND/OBJECTIVES: Urticaria pigmentosa (UP) is the most common form of mastocytosis in children and is associated with systemic signs, symptoms, and triggers. To our knowledge, the effect of UP on children's quality of life has not been studied. The objective of the current study was to characterize the natural history, triggers, and complications of pediatric UP, identify prognostic indicators, and determine its effect on quality of life. METHODS: Between 2002 and 2007, children with three or more mastocytomas diagnosed by a pediatric dermatologist were recruited during visits at the Children's Hospital of Wisconsin Dermatology Clinic (Milwaukee, WI)...

BACKGROUND: Progressive multifocal leukoencephalopathy (PML) is a rare opportunistic brain infection caused by the human polyomavirus JC (JCPyV). A particular problem with the drug cladribine seems to be prolonged suppression of the CD4+ T-cells, a well-known risk factor for PML. CASE DESCRIPTION: A 67-year-old male presented with a 3-weeks history of unsteady gait, dysarthria and a dysfunctional right arm. Seven years earlier, he had been diagnosed with urticaria pigmentosa, and 2 years later aggressive systemic mastocytosis...

Mastocytosis is a group of diseases related to abnormal accumulation and proliferation of mast cells in one or more organs. They may be associated with an acquired point mutation and the activation of the receptor tyrosine-kinase c-KIT of CFS (mast cell growth factor). The clinical manifestations are varied and secondary to the release of mast cell mediators and/or infiltration of various organs. There are two main types of mastocytosis: pure cutaneous mastocytosis and systemic mastocytosis when more than two organs are involved in mast cell infiltration (bone marrow, gastrointestinal tract, bone, liver and spleen, lymph nodes)...

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)...

Systemic Mastocytosis (SM) is characterized by accumulation of clonal, neoplastic proliferations of abnormal mast cells (MC) in one or more organ system other than skin. Presence of these multifocal clusters of abnormal mast cells is an essential feature of SM. Frequently associated with D816V (KIT) mutation, the presence of this mutation and elevated serum tryptase are minor criteria for diagnosis. SM manifestations depend on the degree of mast cell proliferation, activation and degranulation. SM has a variable prognosis and presentation, from indolent to "smoldering" to life-threatening disease...

Systemic mastocytosis is defined as a clonal increase of mast cells. We report on four patients with severe osteoporosis and histologically confirmed systemic mastocytosis. In spite of antiresorptive therapy the patients developed further vertebral fractures and suffered from ostealgia. Systemic mastocytosis is an important differential diagnosis in patients with therapy refractive and unexplained osteoporosis. Skin involvement (urticaria pigmentosa) is a rare occurrence and in most cases an isolated involvement of bone marrow is present...

BACKGROUND: Cutaneous mastocytosis is a rare benign disease occurring in domestic animals and humans. In previous reports, dermal findings in foals were accompanied by systemic mast cell infiltrations, whereas lesions in human cutaneous mastocytosis, including urticaria pigmentosa and solitary mastocytoma, are usually restricted to the skin. OBJECTIVES: To describe a new variant of equine cutaneous maculopapular mastocytosis lacking systemic involvement. ANIMALS: A 2...

BACKGROUND: Presently, no validated data exists on symptom severity and disease-specific quality of life (QoL) for mastocytosis patients. Simultaneously, clinical trials and drug application processes increasingly mandate reporting patients' perspectives on symptoms and QoL. We report on the development and validation of the mastocytosis quality of life questionnaire (MQLQ) and the mastocytosis symptom assessment form (MSAF). METHODS: Both outcome measures were developed in a standardised stepwise method, starting with the identification of items in focus groups (n= 12), item reduction and subsequent cross-sectional validation in a 63% female cohort of 164 adult indolent systemic mastocytosis patients...

Cutaneous mastocytosis, which resembles a subset of urticaria pigmentosa in humans, is rare in dogs. We herein report unrepresentative neoplastic proliferation of mast cells in ventral skin removed routinely from a nine-month-old female laboratory beagle dog at necropsy. A histological examination revealed diffuse extensive cellular infiltration from the superficial to deep dermis in most parts of the skin around the fourth and fifth mammary papilla without nodule formation. Tumor cells were fairly monomorphic, well-differentiated mast cells with round nuclei of small distinct nucleoli and moderate to abundant, slightly eosinophilic and granular cytoplasm...

Urticaria pigmentosa is a rare disorder characterized by an abnormal systemic proliferation of mast cells. In this condition, various triggers can induce either cutaneous histamine release, resulting in rash, or generalized histamine release, resulting in symptomatic hypotension, syncope, or in its severest form, an anaphylactoid reaction resistant to most resuscitative measures. Many anesthetic agents and adjuncts are known potential triggers, and patients who require surgery or procedures under anesthesia must be managed carefully...

Cutaneous lesions in patients with mastocytosis are highly heterogeneous and encompass localized and disseminated forms. Although a classification and criteria for cutaneous mastocytosis (CM) have been proposed, there remains a need to better define subforms of cutaneous manifestations in patients with mastocytosis. To address this unmet need, an international task force involving experts from different organizations (including the European Competence Network on Mastocytosis; the American Academy of Allergy, Asthma & Immunology; and the European Academy of Allergology and Clinical Immunology) met several times between 2010 and 2014 to discuss the classification and criteria for diagnosis of cutaneous manifestations in patients with mastocytosis...
