- Abstract
Background: Dermatophytosis is a very common skin infection with a broad clinical spectrum. Biopsies are often used to confirm the diagnosis, especially when the clinical presentation is unusual. Not uncommonly, organisms are hard to find even with periodic acid-Schiff stains. Polymerase chain reaction (PCR) for dermatophytes can be used in such cases., Objectives: To test a new PCR assay allowing species identification of dermatophytes on paraffin-embedded biopsies, and to reassess histopathological criteria for diagnosis of dermatophytosis., Methods: In total, 121 biopsies of 92 patients with clinical suspicion of tinea were included. In 42 samples the clinical diagnosis had been confirmed histopathologically, and in 79 no fungal elements had been identified. PCRs targeting the internal transcribed spacer (ITS)2 region of dermatophytes were performed on the biopsies with subsequent sequencing. Sections were reassessed for the presence/absence of hyphae/spores, pattern and composition of infiltrate, and epidermal/follicular changes. Patient charts were reviewed for clinical data., Results: The new ITS2 PCR assay detected 94% of the dermatophyte infections (compared with 79% identified by microscopy). Trichophyton rubrum was the dominant species (89%), and other species identified were Trichophyton verrucosum (2%), Microsporum canis (4%), Epidermophyton floccosum (2%) and Trichophyton interdigitale (4%). In particular, infections with T. interdigitale and manifestations with prominent spongiosis were not diagnosed histologically. Intracorneal neutrophils, which have been emphasized as a histopathological clue to dermatophytosis, were present in only 46% of PCR-positive samples., Conclusions: Molecular species identification of dermatophytes via ITS2 PCR can easily be implemented in a routine dermatopathology setting. It is fast and highly specific and improves the sensitivity of histopathological diagnosis of dermatophytosis., (© 2015 British Association of Dermatologists.)

- Abstract
Background: The World Health Organization is strongly promoting alcohol-based hand rubs to interrupt transmission of pathogens within the healthcare environment, and in some hospitals they are being recommended in cases of scabies. However, there are no studies that demonstrate the efficacy of such hand rubs against scabies., Aim: To evaluate the viability of Sarcoptes scabiei after the application of various topical antiseptics used for hand hygiene, and the effect of hand washing on the number of parasites present on the skin surface of a patient with scabies., Methods: We applied three different topical antiseptics (two alcohol-based and one povidone-iodine-based) to the skin of one hand that was affected by scabies, and took a skin scraping of each area to evaluate the viability of the mites over time. A skin scraping of a control area without antiseptic application was also taken. We also tested the antiseptics directly on the mites. Statistical comparison between the percentages of vital mites in the different samples was assessed using the χ(2) test. We also captured a dermoscopic image of the other hand before and after hand washing to count the number of parasites on the skin surface., Results: Topical antiseptics did not reduce the number of living mites compared with control skin, and hand washing did not reduce the number of parasites on the skin surface., Conclusions: Application of topical antiseptics does not reduce the viability of S. scabiei, and is therefore unable to prevent the transmission of scabies. The usefulness of hand washing in preventing transmission of scabies to new subjects remains to be investigated., (© 2014 British Association of Dermatologists.)

- Abstract
Background: Tungiasis is endemic in poverty-stricken communities of South and Central America, Africa, Asia, and the Caribbean. This ectoparasitosis, caused by the female sand flea Tunga penetrans, is associated with considerable longterm morbidity in severely affected patients, including toe deformation and limited mobility. In Haiti, tungiasis is poorly documented but is known to occur. This study is the first formal investigation of tungiasis in Haiti., Methods: A total of 383 patients in four regions (Belle Fontaine, Vallue, Savanette, Cerca Carvajal) were examined and interviewed to determine disease prevalence, demographics and clinical presentation, and tungiasis-related behaviors., Results: Prevalences of tungiasis ranged from 10.6 to 81.8% across the four regions. The overall prevalence of tungiasis in the patients examined was 31.1%. Of the affected patients, 63% were male and 37% were female, 37% were aged 0-10 years, and 100% reported pain and pruritus. Lesions occurred on the feet in 93.3% and on the hands in 22.7% of affected patients. The most common complications observed were chronic inflammation (54.2%) and hyperkeratosis (48.2%)., Conclusions: This study establishes tungiasis as endemic in four regions of Haiti and reveals disease characteristics similar to those reported previously, suggesting that there are common factors underlying this disease in various regions, which are likely to be poverty-related. These findings emphasize the need to acknowledge tungiasis as a clinically relevant public health issue in order to decrease the frequency of tungiasis-related morbidity in endemic areas., (© 2014 The International Society of Dermatology.)

- Abstract
We describe the case of a 44-year-old homosexual man diagnosed with HIV infection and visceral leishmaniasis. He presented nodules on the dorsum of the hands. Histological study of one of the nodules revealed necrobiotic palisading granulomas with abundant Leishmania amastigotes within the histiocytes and in the adjacent extracellular space. Tissue and peripheral blood cultures were positive for Leishmania infantum, zymodeme MON-24. A biopsy of healthy skin did not reveal the presence of Leishmania. A diagnosis of rheumatoid nodulosis with Leishmania was made and treatment was started with intravenous liposomal amphotericin, leading to slight improvement. We believe that the presence of the parasite within the nodules was the result of its dissemination during visceral leishmaniasis in an immunocompromised patient with HIV infection, and that the Leishmania did not have an etiological role in the appearance of the nodules. We present the first case of the association between Leishmania and rheumatoid nodulosis.

- Abstract
The cutaneous leishmaniasis (CL) is an affection which is quite well known in Tunisia. The zoonotic cutaneous leishmaniasis caused by Leishmania major by far the more frequent, is endemo-epidemic in the centre and south of the country. It is characterized by clinical polymorphism. The aim of our study is to precise the different clinical aspects of the CL in our region through a prospective study of 102 cases. The average age was 37.8 years old (from 4 to 78 years old) with a slight female predominance. All of our cases lived or stayed in an endemic zone. Various clinical forms were noted in our series. The ulcerated and crusted form was predominant: 54,9% of the cases, the lupoid form was noted in 15.7% of the cases and the sporotrichoid form was observed in 18.6% of the cases. Other rare forms were noted (papular erysipeloid, verrucous, vegetant, erythematous, ulcerated, necrotic and linear) were noted in 25.5% of the cases. Our series is characterized by the multiplicity of clinical forms. Besides, the classical form (ulcerated and crusted form), other clinical form can be individualised: lupoid, loco regional spreading (sporotrichoid form, satellite papules). Some atypical forms can be found which are due to variation of host immune responses and to the strain of the parasites involved.

- Abstract
Crusted scabies has been defined as a scabies-induced psoriasiform dermatosis on the hands and feet with dystrophy of the nails and an erythematous scaling eruption that may be generalized. This case report demonstrates a patient who presented with widespread psoriasiform plaques that were teeming with scabies mites and eggs, but who had absence of nail and palmar involvement. While patients with crusted scabies may have nail dystrophy and involvement of the palms, this involvement is not necessary.

- Abstract
Background: Leishmaniasis associated with HIV/AIDS has been reported in the last decade., Case Report: A case of generalized cutaneous leishmaniasis in a patient with AIDS is described. The case is paradoxical in that the cutaneous lesions resemble anergic leishmaniasis caused by Leishmania (L.) amazonensis and Jorge Lobo's disease, but the positive Montenegro test and the clinical improvement with antimonial are more commonly observed in leishmaniasis caused by L.(V.) braziliensis., Comment: The immunosuppression due to HIV/AIDS seen in this patient may explain the dissemination of the lesions, but the positive specific response to leishmanial antigen may explain the good response to the antimonial treatment.

- Abstract
A 33-year-old man presented with very itchy red papules on the back of his hands and forearms. These papules appeared about 90 min after he had cleaned his aquarium in which he kept native fish and watersnails. He had obtained the watersnails some weeks before from a nearby pond. Examination of water from the aquarium revealed cercariae. The clinical diagnosis of cercarial dermatitis was corroborated. Cercarial dermatitis has repeatedly been seen in swimmers but not in aquarists keeping fish in a home aquarium.

- Abstract
Three patients are described with leishmaniasis and AIDS, with cutaneous lesions mimicking dermatomyositis. Leishmania organisms were observed in great numbers in the dermis of lesional skin biopsy specimens. They were also present inside keratinocytes in all layers of the epidermis in one patient. Skin cultures from all patients and bone marrow culture in patients 1 and 3 revealed Leishmania infantum. Leishmania organisms were also found in nonlesional skin. The absence of proximal symmetric muscle weakness, elevated muscle enzymes, myopathic electromyograms, or characteristic histopathologic and immunologic features of dermatomyositis, and the rapid and complete clearance or marked improvement of the cutaneous lesions after treatment for leishmaniasis, make us consider true dermatomyositis unlikely. We suggest that leishmaniasis be included in the list of diseases capable of inducing a dermatomyositis-like eruption.
