Herein, a 12-year-old Afghan boy with chronic cutaneous leishmaniasis on the face and verrucous lesions on the body and pleural effusion suspected of having co-existent tuberculosis has been presented. The cutaneous lesions were appeared for five years before his admission. Leishman-Donovan bodies were seen in H&E (Hematoxylin and eosin) slide of skin lesion specimens. The pathogenic species wa...

the agency through which a new disease is produced. The disease differs entirely from drug eruptions in being a specific parasitic affection which follows the administration of antimony salts by the intravenous route. It is possible t\hiat the disease may occur under other conditions but there is no evidence that this takes place, and it is not likely that a dermal leishmaniasis of so distinct ...

Leishmaniasis is a worldwide tropical infectious disease caused by different species of intracellular protozoa parasites of the genus Leishmania . Herein, we report a 78-year-old man with unusual diffuse cutaneous leishmaniasis (DCL) who had a history of opium abuse and chronic obstructive pulmonary disease (COPD). He had multiple papular, crusted and severely ulcerated lesions extended to his ...

Deregulated CD8+ T cell cytotoxicity plays a central role in enhancing disease severity in several conditions. However, we have little understanding of the mechanisms by which immunopathology develops as a consequence of cytotoxicity. Using murine models of inflammation induced by the protozoan parasite leishmania, and data obtained from patients with cutaneous leishmaniasis, we uncovered a pre...

Visceral leishmaniasis is endemic in District Dir, NWFP. We evaluated 10 patients with visceral leishmaniasis at DHQ Hospital Timergara District Dir, N.W.F.P. All patients were in the age range 2 to 10 years. The predominant clinical features in these were chronic fever (10), splenomegaly (10), hepatomegaly (10), weight loss (10) and abdominal distention (5). Lymphadenopathy was absent. Common ...

This case report describes an atypical case of duodenal leishmaniasis in an elderly patient not infected with human immunodeficiency virus. Investigation of this 84 year old woman with a constitutional syndrome and dysphagia revealed anaemia of chronic disorder, a high erythrocyte sedimentation rate, and polyclonal hypergammaglobulinaemia. Abdominal ultrasonography revealed thickening of the st...

Statement of the problem: Nowadays leishmaniasis is a common infectious disease around the world which is caused by a protozoan parasite named Leishmania. This parasite is transmitted to human by an infected female sand fly. This disease has three clinical forms; mucosal forms are rare in Iran. Purpose: The purpose of this study was to report a case of leishmaniasis with lip and oral mucosal in...

About 50 to 70% of sera from patients with American cutaneous leishmaniasis and chronic Chagas' disease possessed antibodies which reacted in enzyme and radioimmunoassays with nidogen obtained from a tumor basement membrane. The antibodies were of the immunoglobulin M and G classes in acute American cutaneous leishmaniasis but mainly of the immunoglobulin G class in chronic Chagas' disease. Sim...

The levels of protection found in vaccine studies of murine visceral leishmaniasis are significantly lower than for cutaneous leishmaniasis; whether this is due to the high-challenge murine model employed and/or is a consequence of differences required in tissue-specific local immune responses is not understood. Consequently, an intradermal murine model of visceral leishmaniasis has been explor...
