Wet lesion by L. major
L. major occurs most commonly in rural areas, causing moist, ulcerative lesions which may be extensive and sometimes involve the epithelium of lips and nose.
These are the commonest types of lesion caused by L. major.Prominent ‘rolled’ edge of the lesions is the best area to demonstrate the parasites
![Page 38: Massive Splenomegaly By Dr Bashir Ahmed Dar Chinkipora Sopore Kashmir Associate Professor Medicine](https://reader036.fdocuments.net/reader036/viewer/2022062303/554b3276b4c905a2058b506f/html5/thumbnails/38.jpg)
Lymphatic spread of L. major
The ink marks indicate a line of subcutaneous nodules along the lymphatic, passing proximally from the lesion on the lower part of this man’s arm.The nodules usually resolve without complications when the primary lesin heals with or without specific therapy.

Simple ‘dry’ lesion by L. tropica
dry, usually self-healing lesions, Generally singleUrban area in North Africa and the Middle East to the former USSR, Afghanistan, western states of IndiaThe lesions frequently contain very large numbers of parasites.
![Page 41: Massive Splenomegaly By Dr Bashir Ahmed Dar Chinkipora Sopore Kashmir Associate Professor Medicine](https://reader036.fdocuments.net/reader036/viewer/2022062303/554b3276b4c905a2058b506f/html5/thumbnails/41.jpg)
Leishmaniasis recidivans
Infection with L. tropica may become very chronic, with a hyperallergic reaction leading to lupus-like lesions such as seen in this child.Amastigotes may be very difficult to find in the lesions.
![Page 42: Massive Splenomegaly By Dr Bashir Ahmed Dar Chinkipora Sopore Kashmir Associate Professor Medicine](https://reader036.fdocuments.net/reader036/viewer/2022062303/554b3276b4c905a2058b506f/html5/thumbnails/42.jpg)
Mucocutaneous lesion by L. aethiopica
In addition to simple cutaneous lesions due to infection with L. aethiopica, other forms are seen in the Ethiopian highlands where rock hyraxes are the reservoirs. It has not yet been ascertained whether the mucocutaneous condition seen here is due to this or another species of Leishmania.

Lymphatic spread of
L. mexicana
As noted for L. major, lymphatic spread may also occur with New World species. This patient was infected with L. guyanensis the agent of ‘Pian bois’. In such infections the lymphatic nodules may ulcerate.

Pharyngeal involvement
Ulceration often extends to the pharynx and soft palate, and the first symptoms may be related to tissue destruction in this area.
This man had the scar of a large ulcer which had apparently healed on his leg some 30 years before.

Clinical picture of kala-azar in Kenya
Increasing enlargement of the spleen and liver is a characteristic feature while, in dark-complexioned subjects, deepening skin pigmentation is seen-hence the synonym kala-azar, the ‘black sickness’.
A generalized lymphadenopathy is common in African kala-azar; the parasite in this area is considered to be in the L. donovani complex.

Iliac crest aspiration of bone marrow
The most direct means of diagnosis of kala-azar is the detection of amastigotes in bone-marrow, spleen or blood; the organisms are recognized in dried smears of material stained with a Romanowsky stain by their characteristic morphology.
