Oriental sore
Oriental sore. The originator - Leishmania tropica (minoro). It is extended in cities of the Mediterranean, Near and Middle East, the western part of Hindustan peninsula.
Incubation interval fluctuates from 2-4 months till 1-2 years. Elongation of an incubation till 4-5 years is possible. Both at antropos, and at a zoonotic leishmaniasis following clinical forms of illness can be observed:
- a primary leishamanioma:
- Stage of a hillock
- Stage of an ulceration
- Cicatrisation stage
- a consecutive leishamanioma
- Diffusive-infiltrative leishamanioma
- Tuberculoid dermal leishmaniasis. Last two forms arise at antropos a leishmaniasis type is more often
Oriental sore begins a little an appreciable papule - a hillock in diameter of 2-3 mm. It does not tower almost over level of a surrounding healthy skin, without visible inflammatory changes, some time can not be noticed by the diseased. Its colour slightly brownish, in the hillock centre at attentive studying (through a magnifier) it is possible to find the small central fossa quite often filled with dry flake, as though a stopper which can be removed a scalpel end. Gradually it is enlarged in the dimensions, in 3-6 months reaches the dimensions of 5-10 mm, the skin over it becomes burovato-red, the smooth or rugosity bottom covered with purulent scurf becomes covered by a scutal crust at which excision the ulcer having the round form is formed. Round an ulcer the infiltrate at which disintegration the ulcer dimensions are gradually enlarged is formed. Ulcer edges saped, rough; a discharge insignificant. Gradually the cicatrisation of an ulcer which comes to an end approximately in a year from the illness beginning begins, is sometimes tightened till 1,5-2 years. On an ulcer place there is a cicatrix, in the beginning pink, then acyanotic. Number of ulcers 1-3 (to 10), they settle down usually on the open fields of a skin accessible to mosquitoes (the person, arms). Sometimes educe diffusively - infiltrate leishamaniomas with the big region lesions (more often on brushes, stops) and without predilection to ulcerations and formation of cicatrixes. On the big extent the skin appears stagnation red, infiltrated, is thin husking, smooth or slightly hilly. On the general infiltrate separate small ulcers can be scattered.
