c) Clinical picture
The first lesion start with a papule it can grow to nodules or it can be ulcerated and
can be covered with crust.
Lesions are small papules that develop in to non-ulcerated dry plaques or large
encrusted ulcers with well-demarcated raised and indurate margin.
¾ The lesion may be single, multiple or diffuse may be self limiting or can be
chronic
¾ If it is mucocutaneous the lesion appears as single or multiple papules. The
lesion first is nodular and then becomes ulcerated and wart like that can be
painful. Some times the lesion appears as single nodule but later on can be
indurate and involve on nasal mucosa and skin and lead to destructions.
¾ In case of diffuse cutaneous leishmania which is caused by L-Mexican and L.
aethiopica, the multiple modules lesion is a non ulcering lesion, and occurs on
the entire body
¾ Involvement of lesion in naso -pharyngeal tissue, is severely disfiguring and
often fatal
Mucocutaneous leishmaniasis causes extensive destruction of the soft tissue &
cartilage of the nose, oral cavity and lip and extends to the larynx & pharynx.
