BACKGROUND: Although pityriasis versicolor (PV) is a common fungal infection of the skin affecting up to 50% of the population in the tropics, little is known about what patients know, believe, or feel about the condition. METHODS: In a cross-sectional questionnaire study of 608 consecutive patients attending the General Outpatient Department and Skin Clinic of a public hospital in Kaduna, Nigeria, self-report of PV, knowledge about its causes, treatments used by patients, and perception and feelings about the condition were assessed...

We report two cases of Pityriasis versicolor (PV) in infants aged 12 and 18 months. The latter were brought to medical attention because of hypochromic and achromic, round macules involving the limbs and the face. Physical examination of their mothers showed voluntary depigmentation for cosmetic purposes due to the use of corticosteroids and hydroquinone, on average, over a 5-year period. The scotch tape test performed in one of the infants and his mother showed short filaments and clusters of spores. Treatment was based on ketoconazole...

Malassezia spp. are lipophilic yeasts not only present in the normal skin microflora, but also responsible of skin-related diseases (pityriasis versicolor, seborrheic/atopic dermatitis and dandruff) as well as systemic fungal infections in humans and animals. Their treatment and eradication are mainly based on old azole drugs, which are characterized by poor compliance, unpredictable clinical efficacy, emerging resistance and several side effects. These drawbacks have prompted the research toward novel synthetic and natural derivatives/nanomaterials targeting other pivotal enzymes/pathways such as carbonic anhydrase (MgCA) and lipases, alone or in combination, in order to improve the eradication rate of this fungus...

BACKGROUND: Demodicosis is a parasitic skin disease caused by Demodex mites, and the determination of mite density per square centimeter is important to diagnose demodicosis. Standardized skin surface biopsy (SSSB) and direct microscopic examination (DME) are commonly used to determine Demodex mites density (Dd). However, no study has previously compared these two methods with respect to clinical types and distribution patterns of demodicosis. OBJECTIVE: The aim of this study was to compare the value of SSSB and DME findings in reference to the clinical types and distribution patterns of demodicosis...

Malassezia is a genus of lipid-dependent yeasts. It is associated with common skin diseases such as pityriasis versicolor and atopic dermatitis and can cause systemic infections in immunocompromised individuals. Owing to the slow growth and lipid requirements of these fastidious yeasts, convenient and reliable antifungal drug susceptibility testing assays for Malassezia spp. are not widely available. Therefore, we optimized a broth microdilution assay for the testing of Malassezia that is based on the CLSI and EUCAST assays for Candida and other yeasts...

BACKGROUND: Direct immunofluorescence (DIF) is considered pivotal in diagnosing autoimmune blistering diseases. Our goal was to examine the necessity of DIF in intraepidermal bullous cases, of which pemphigus vulgaris (PV) is the prototype. METHODS: Sixty-six cases from 2010 to 2014 submitted for DIF with an intraepidermal blistering disease listed in the differential diagnosis were reviewed by 2 board-certified dermatopathologists to see if they would order DIF based on routine histologic findings...

Pityriasis rosea is a common, self-limited and inflammatory skin disease. The etiology is not clearly known. Viral agents, autoimmunity, psychogenic factors and drugs have all been suggested as risk factors. Isotretinoin is usually used in the treatment of resistant, nodulocytic acne. We present a case of pityriasis rosea-like eruption induced by isotretinoin. To our knowledge, this is the second clinical case of pityriasis rosea-like eruption induced by isotretinoin.

A. sieberi essential oil has been used for treatment of hardly curable infectious ulcers in Middle East Medicine and has been famous due to its wormicide effects. In this review, we evaluated the potency of A. sieberi essential oil in treatment of fungal infections. We searched in PubMed Central, Science direct, Wiley, Springer, SID, and accessible books, reports, thesis. There is a lot of mixed information on chemical compositions of A. sieberi essential oil, but most articles reported α, β-thujones as the main components of essential oils...

Pierre Halteh, Shari R Lipner
Pityriasis rosea (PR) is an acute self-limited exanthem characterized by oval erythematous patches with scale and may be difficult to differentiate from secondary syphilis. A rapid plasma reagin (RPR) test can be used to rule in secondary syphilis with high sensitivity and specificity. A retrospective study was performed on patients at Weill Cornell Medicine, who were diagnosed with PR from 2000 to 2016 and also received RPR testing at the time of diagnosis. The objective was to assess the frequency of secondary syphilis when the initial clinical impression was PR...

Lipophilic yeast Malassezia species is widely found on the skin surface of humans and other animals. This fungus can cause pityriasis versicolor, Malassezia folliculitis, and seborrheic dermatitis. Still now, there is a problem with species identification of Malassezia with conventional methods. We developed a real-time polymerase chain reaction (PCR) assay with multiple hybridization probes for detecting M. globosa, M. furfur, M. restricta, M. sympodialis, M. slooffiae, and M. pachydermatis. The amplification curves and specific melting peaks of the probes hybridized with real-time PCR product were used for species identifications...

Pityriasis Rosea (PR) is a common skin disorderencountered in daily practice. Although its etiologyhas not been established, there has been widespreadresearch into possibilities. The lack of its characteristicmanifestations, specifically the herald patch andtruncal involvement, can lead to pitfalls in diagnosis.Whereas other conditions in the differential diagnosisshould be considered, PR can at times also manifest inan atypical manner. We wish to illustrate three casesof PR including those that presented with aphthousulcers, vesicles, and an inverse pattern...

Pityriasis rubra pilaris (PRP) represents a group of rare chronic inflammatory skin disorders in which ~1 in 20 affected individuals show autosomal dominant inheritance. In such cases, there may be gain-of-function mutations in CARD14, encoding caspase recruitment domain-containing protein 14 (CARD14) that activates the non-canonical nuclear factor-kappa B (NF-κB) pathway, thereby promoting cutaneous inflammation. Here, we report a mother and son with PRP due to a new missense mutation in CARD14 and describe the beneficial clinical effects of ustekinumab, a monoclonal antibody against interleukins-12 and -23, in both subjects...

In 2012, gain-of-function mutations in CARD14, which encodes caspase recruitment domain family member 14, were identified as the cause of familial psoriasis vulgaris (PV) and familial pityriasis rubra pilaris (PRP).(1,2) We and another group reported that CARD14 variants are associated with generalized pustular psoriasis (GPP) and palmoplantar pustular psoriasis (PPP).(3-5) The other reports mentioned that CARD14 mutations in individuals with GPP and erythrodermic PRP. (4,6) Very recently, we described PRP type V as an autoinflammatory disease caused by CARD14 mutations...

Pityriasis rubra pilaris (PRP) and plaque psoriasis (PP) are two distinctive erythemato-squamous skin diseases that often have to be differentiated from each other and from other similar dermatoses. Dermoscopy has been proven to aid the clinical diagnosis of several inflammatory disorders, minimizing the need for skin biopsy. Our aim was to determine the dermoscopic patterns of PRP compared to PP and to assess the significance of certain dermoscopic criteria in the diagnosis of PRP. This case-control study included 11 patients with biopsy proven PRP and 25 patients with biopsy proven plaque psoriasis...

BACKGROUND: Pityriasis lichenoides is an uncommon skin disease that presents in three different forms: pityriasis lichenoides et varioliformis acuta (PLEVA), pityriasis lichenoides chronica (PLC) and febrile ulceronecrotic-Mucha-Habermann disease. These represent a spectrum of a disease. PLEVA presents as skin eruption of multiple, small, red papules that develop into polymorphic lesions with periods of varying remissions, as well as possible sequels of hyper/hypopigmentation and varicella-like scars...

REVIEW
Alejandro A Gru, Andrea L Salavaggione
This review article focuses on the spongiotic tissue reaction pattern and some of the common entities that practicing pathologists can frequently encounter in their practice. The spongiotic tissue reaction pattern is the single most common one encountered in the routine analysis of inflammatory dermatoses, and the most non-specific one as well. Spongiotic dermatoses include a very large list of disorders which are best grouped under neutrophilic, eosinophilic, miliarial, follicular and pityriasiform forms of spogiosis...

RATIONALE: Paraneoplastic pemphigus (PNP) is an autoimmune syndrome associated with neoplasms. The treatment approach principally includes suppressing the immunity, but its therapeutic effect is not satisfying. PATIENT CONCERNS: We report a case of paraneoplastic pemphigus linked to chronic lymphocytic leukemia in a 63-year-old man. DIAGNOSES: At first, the patient was diagnosed with pityriasis rose caused by a viral infection. Biopsies for histology and immunofluorescence showed PNP, was treated with immunosuppressive and antiinfective therapy...
