RESUMO
Gamasoidosis is a poorly known and underdiagnosed mite infestation. It is characterized by the presence of erythematous and flattened papules that are quite pruritic, and can affect any region of the body, with preference for areas of folds. This article reports a case of the disease caused by mites of the species Dermanyssus gallinae. Increasingly, the agents that cause this disease are found in urban environments, increasing the incidence of people affected by the disease. This dermatosis has a self-limiting clinical picture and the treatment is done with the use of topical corticosteroids and oral antihistamines.

Cutaneous leishmaniasis is a parasitic disease caused by the Leishmania species, transmitted by the bite of an infected sandfly. The typical cutaneous lesion is a painless ulcer with a raised, indurated margin and often covered with an adherent crust. The lesions are mostly located on exposed sites such as the face and the extremities. Eyelid involvement is rare, making up only 2-5% of cases with facial cutaneous leishmaniasis. Herein, we report a 50-year-old male who presented with an erythematous plaque on the upper eyelid and multiple ulcerated nodules located on the extremities. Following microscopic examination of the lesional smear, a diagnosis of cutaneous leishmaniasis was made, and the patient was successfully treated with intramuscular meglumine antimonate therapy.

The European eel (Anguilla anguilla) is a critically endangered species. Red anus syndrome (RAS) is known to be associated with parasitic infections of the eel, particularly with Anguillicola crassus, but the full range of causative pathogenic organisms has not been systematically investigated. Here we examined the infective organisms and histopathological and ultrastructural features of seventy eels with RAS. In total, nine different pathogens were detected in association with RAS: Pseudomonas aeruginosa were present in twelve specimens (17%), the metacercaria of Euclinostromum heterostomum in three cases (4%), Gastrostome (Bucephalidae family) in seven cases (10%), A. crassus in forty-five cases (64%), Bothriocephalus in seventeen cases (24%), and Proteocephalus in twenty-three cases (32%). Yeast, amoeba, and myxobolus-like pathogens were seen in the anal skin in all cases when examined in combination with electron microscopy. Histopathologically, the lesions appeared as anoproctitis of varying severity from mild anusitis to severe haemorrhagic anoproctitis, with severe perianal oedema, haemorrhage, and proctoptosis. Gut inflammation ranged from mild catarrhal enteritis to severe haemorrhagic enteritis with mucosal sloughing. RAS is associated with a range of parasitic infections, not only A. crassus, some of which we describe here for the first time. Since RAS is not associated with direct invasion by parasites, it is likely that RAS is a secondary phenomenon caused by superadded infection on a background of generalised immunosuppression, or indirect local toxic effects. RAS may be used as a non-invasive indicator of underlying parasitic infection, but further investigations are required to establish the causative organisms for effective fishery management.

OBJECTIVE: The aim of the study was to determine the prevalence of Demodex sp. in patients referred fom the Dermatology Outpatient Clinic to the Parasitology Laboratory, Dursun Odabas Medical Center of the Yüzüncü Yil University. METHODS: The study was conducted between May 2012-May 2013. The samples were taken from 67 patients using the standard skin surface biopsy method. RESULTS: Demodex sp. mites were identified in 47.4% of 38 women, and in 48.3% of 29 male patients. These mites were detected in 15.8% of 19 patients who were 35 years old and younger, and in 60.4% of 48 patients who were 36 years old and older. Overall, 47.8% (32 patients) of 67 patients were found positive for demodicosis. It was determined that 53.1% of Demodex sp. positive patients had eritemato telangiectatic rosacea, 21.9% had papulo-pustular type rosacea, 18.8% had papules, 3.1% had erythematous pustules, and 3.1% had erythematous squamous plaques. There was a statistically significant difference between the Demodex sp. positivity and age groups (p=0.001). CONCLUSION: It was concluded that dermatologists should also take into consideration the possible presence of Demodex sp. mites in patients with skin symptoms such as erythema, telangiectasia, papules and pustules, and apply the appropriate treatment for these parasites.

Skin lesion is common in person living with HIV. We reported a 42 years old HIV positive man with single erythema skin lesion on the right foot. Clinical examination, anamnesis and laboratory examination revealed that it was cutaneous larva migrant due to parasitic infection. The cutaneous larva migrant due to hookworms is one of neglected tropical disease that might occur in adult with immunocompromised. This neglected disease is discussed rarely and might not be found in developed country, but it is still a common disease in the tropical region. Patient was treated successfully with albendazole, cetirizine, chlorethyl spray and betamethasone cream.

BACKGROUND: Previous studies have demonstrated that dermoscopy improves accuracy in diagnosing pigmented and non-pigmented tumors. Recently, there has been increasing evidence that dermoscopy can also be useful in the diagnosis of some skin infections. OBJECTIVE: We sought to describe the dermoscopic features of cutaneous leishmaniasis. METHOD: Dermoscopic examination (using the Derm Lite FOTO, 3Gen) of 144 CL lesions in 82 patients was performed. This study was conducted in the Imam Reza and Ghaem hospitals (Mashhad, Iran) from October 2010 to September 2011. RESULTS: We observed the following dermoscopic features: generalized erythema (81.9%), white starbursts (60.4%), yellow hue (43.8%), yellow teardrop-like structures (41.7%), central ulcers (59%), hyperkeratosis (33.3%), and milia-like cysts (4.9%). We also observed vascular structures, including dotted vessels (61.1%), hairpin vessels (37.5%), linear irregular vessels (30.6%), comma-shaped vessels (29.9%), glomerular vessels (22.9%), arborizing telangiectasia (10.4%), and corkscrew vessels (4.2%). LIMITATIONS: Biopsy and pathologic evaluation were not performed due to ethical considerations. CONCLUSION: Important vascular patterns seen in melanocytic and non-melanocytic tumors were frequently observed in this infection. Dermoscopy may be a promising tool to predict the clinical course in cases of cutaneous leishmaniasis.

BACKGROUND: Cutaneous leishmaniasis (CL) has a worldwide distribution. Delayed and incorrect diagnosis may cause the significant spread of this disease and consequent increases in morbidity and drug resistance. OBJECTIVES: We aimed to determine dermoscopic features of CL that may help to improve the accuracy of clinical diagnosis of the disease. METHODS: A total of 145 lesions in 102 patients were evaluated dermoscopically. Following the diagnosis of CL, all lesions were evaluated by experienced dermoscopists. RESULTS: A total of 51 papules, 40 nodulo-ulcerative lesions, 31 plaques, and 23 nodules were evaluated by dermoscopy. Generalized erythema appeared in all lesions (100%), yellow tears in 58 lesions, both crust and ulcer in 51 lesions, white starburst-like patterns in 27 lesions, ovoid salmon-colored structures in 19 lesions, and a perilesional hypopigmented halo pattern in four lesions. Various vascular structures were present in 126 lesions. The most common vascular structure observed was an irregular linear pattern in 78 lesions, followed by a tree-like pattern in 53 lesions. The rest of the vascular structures included hairpin vessels in 25 lesions, glomerulus-like vessels in 24 lesions, dotted vessels in 23 lesions, comma-shaped vessels in six lesions, and polymorphous/atypical vessels in four lesions. We did not identify the types of parasite involved. CONCLUSIONS: Yellow tears, white starburst-like patterns and salmon-colored ovoid structures seem to appear specifically in CL lesions. In geographical areas in which CL is common, dermoscopy may be utilized as a useful diagnostic tool that is practical and non-invasive.
