Abstract
Since 2000, cutaneous nodular lesions were observed in Tohoku hynobiid salamanders (Hynobius lichenatus) in the northern Abukuma Mountains, northeastern Honshu, Japan. The distribution of diseased salamanders has expanded, along with the increasing severity of the disease. Samples (foreleg, hindleg,...

Abstract
The AMP LL-37 has been identified as regulator of keratinocyte apoptosis. The hypothesis of a direct defense function of keratinocytes, combating bacterial, fungal, virus and parasite infection, is strengthened. The discovery of an IL-22-producing T-lymphocyte subpopulation implicates a role in AMP...

Abstract
Family physicians commonly diagnose and manage penile cutaneous lesions. Noninfectious lesions may be classified as inflammatory and papulosquamous (e.g., psoriasis, lichen sclerosus, angiokeratomas, lichen nitidus, lichen planus), or as neoplastic (e.g., carcinoma in situ, invasive squamous cell ca...

Abstract
Dermatologic disease is common in HIV-infected individuals, and clinicians caring for patients with HIV infection or AIDS in Africa are routinely confronted with skin problems in their patients. Scarce access to dermatologic specialty care and limited educational resources describing the unique clin...

Abstract
Because Demodex mites are ubiquitous, their potential as human pathogens has often been ignored. This contribution focuses on the growing body of evidence linking Demodex mites with various skin disorders. Histologically, spongiosis and lymphoid inflammation are regularly seen in follicles containin...

Abstract
In case of cercarial dermatitis after exposure to fresh water lakes, managers responsible for bathing water quality wish to confirm the presence of Trichobilharzia, which substantiates taking measures to protect bathers from further exposure. A novel approach, including concentration of suspected wa...

Abstract
Tungiasis (sand flea disease) and cutaneous larva migrans (creeping eruption) are parasitic skin diseases in which the infectious agents only temporarily invade human skin. The parasites die in situ and eventually are eliminated by tissue repair mechanisms. Both diseases are zoonoses. Humans only ac...

Abstract
The authors describe a case of cutaneous myiasis caused by Dermatobia hominis in a 23-year-old Italian woman who contracted the infestation during a tour in Jamaica. The infestation was located on the back and was characterized clinically by a single inflammatory nodule. To our knowledge, this is th...

Abstract
In the past decade, swimmer's itch (SI) has repeatedly occurred in people who have been wading or bathing in ponds or lakes in Iceland where water birds and snails are abundant. Some of the affected sites were warmed by geothermal activity, and others were not. A search for the causative agent of SI...

Abstract
'Swimmer's itch' or cercarial dermatitis (CD) results from an immunological reaction to free-swimming non-human schistosome parasites released from aquatic snails. Affected bathers develop a self-limiting, pruritic, macular or papular eruption shortly after leaving the water. The condition is well-r...

Abstract
Delusional parasitosis manifests in the patient's firm belief that they have skin symptoms due to an infestation with insects. Patients often refuse to seek psychiatric care. This study reassessed patients with delusional parasitosis in order to review and learn from them, which is important due to...

Abstract
Human subcutaneous dirofilariasis is an increasingly reported zoonosis caused by several filarial species, in particular by Dirofilaria (Nochtiella) repens. Like many filarial worms, D. repens harbors the bacterial endosymbiont Wolbachia that has been implicated in the inflammatory features of filar...

Abstract
Cutaneous amebiasis always presents with painful ulcers. The ulcers are laden with amebae, which are relatively easy to see microscopically with routine stains. Erythrophagocytosis is an unequivocal sign of CA. Amebae reach the skin via 2 mechanisms: direct and indirect. Amebae are able to reach the...

Abstract
Human dirofilariasis caused by Dirofilaria repens is a parasitic infection, currently considered to be an emerging zoonosis, that has been observed in many areas of the Old World. Dogs are the main 'reservoir' host. In humans, D. repens can cause inflammatory nodules, most commonly in the subcutaneo...

Abstract
In Germany there is little information available about the distribution of the Tropical rat mite (Ornithonyssus bacoti) in rodents. A few case reports show that this haematophagous mite species may also cause dermatitis in man. All developmental stages are exclusively bloodfeeder. Three children (4,...
