The mean age of patients was 19.8 years with extremes from 6 months to 61 years. The sex ratio was 0.76 M / F. The mean duration of lesions was 1.6 months with extremes of 2 weeks to 10 months. Fall preponderance was noted (41.6%). The most frequent clinical appearance was that of a single ulcero-pulmonary nodule (61%) (71.9%) and was seated on the face (57.5%). Cutaneous leishmaniasis continues to pose a real public health problem in our country. The emergence of severe and resistant forms throughout the world should encourage the multiplication and strengthening of prophylactic measures.

INTRODUCTION Described the first time in Morocco in 1914 by Foley and Vialate (Rhajaoui et al., 2004), cutaneous leishmaniasis (CL) is a public health problem in our country. It is sharply recrudescence, due to a flagellated protozoan belonging to the genus Leishmania. The aim of our work is to describe the epidemiological, clinical and evolutionary characteristics of CL in the Ain Dfali health center. 2. METHODS Through a study conducted between Department of Parasitic Diseases and Ain Dfali Health Center, Provincial Delegation of Health Sidi Kacem, during the period from January 2006 to December 2015, including patients diagnosed with cutaneous leishmaniasis with parasitological and histological confirmation. For each patient were specified: the age, the sex, the geographical origin, the duration of evolution, the clinical aspect, the therapeutic scheme used as well as the evolution under treatment. The statistical analysis was performed using the Exel software (2010 version). http://iaeme.com/Home/journal/IJCIET 302 [email protected] Cutaneous Leishmaniasis in Ain Dfali province, West Morocco (2006-2015) 3. FIELD OF STUDY The commune Ain Dfali Figure 1 is limited to the West by commune Sidi Azouz Sidi Kacem province, to the North commune of Rurale Bni Oual province Sidi Kacem, to the common East Ouennan province Ouazzan, and to the South by municipality Rural Mrabih province Sidi Kacem . It covers approximately 234 km2. Its population is 24181 (projection 2009). This area has a high climatic diversity in mountainous areas, the climate is moderate with a hot and dry summer with temperatures ranging from 7 ° C to 47 ° C and average winter rainfall of 500 to 700 mm.

DISCUSSION Cutaneous leishmaniasis has a circum-terrestrial geographical area. According to the WHO, the population at risk of leishmaniasis is estimated at 350 million people (WHO, 2010). The global incidence of LC, in all clinical forms, is between 1 and 1.5 million / year. More than 90% of LF cases come from Afghanistan, Iran, Saudi Arabia and Syria for the old world, Brazil and Peru for the new world (Momeni, 1994). Morocco is an endemic country of the LC. Infection occurs in three noso-geographic forms: the zoonotic LC to Leishmania major in the south, the anthroponotic LC to Leishmania tropica in the center with emergence of new outbreaks in the north and the sporadic LC to Leishmania infantum in the north whose first Moroccan case has revealed in 1996 (Rhajaoui 2004, Guessous 1994, Chihab 1999). Between 2007 and 2011, 27457 cases of CL were identified (Ministry of Health Morocco, 2012). The analysis of the epidemiological data revealed a control of the LC profile at L. major in the majority of the old foci with a reactivation observed during the year 2010. Moreover, the LC to L. tropica has experienced outbreaks epidemic (El Assri, 2016). LC affects all ages and the child can be exposed to the disease in the first months of life (6 -10). We note a predominant impairment of school-aged children, especially those over ten years of age (38.6% of cases). The distribution of LC by sex is variously appreciated in the literature (EL Aasri, 2015). There does not seem to be any significant difference in our series. Clinically, our results are superimposable to those of the literature. The predominance of the ulcero-crustal form in our series, noted also in the other studies carried out in North Africa, is explained by the frequency of LC to L. Major (Guessous, 1999). The latter form is characterized by multiple lesions, localization at the level of the regions discovered especially at the level of face and limbs as well as the short duration of evolution (Aoun, 2012). The long consultation time found in our work is explained by the slowly insidious, indolent and benign nature of the lesions. In our context, the diagnosis is often made in autumn or winter away from the contamination that occurred in summer (after a stay in endemic area). Numerous clinical presentations are possible during LC, the impetigo, warty, vegetative, lupoidal, pseudotumoral, psoriasiform, lichenified, ulcerous, echtymatous, lymphangitic, abortive, sporotrichoid and nodular forms. This clinical polymorphism does not only depend on the genetic characteristics of the parasite, but also on the immunological status of the host. Indeed, the balance of functional phenotypes of CD4 T lymphocytes plays an important role in the determinism of this affection; schematically the Th1-type response corresponds to a benign localized lesion, the Th2 response involves extensive severe injury. Leishmania-HIV co-infection is currently considered an emerging disease, especially in southern Europe (Dedet, 2000). WHO estimates that 1.5 to 9% of AIDS patients have visceral leishmaniasis (Momni, 1994). The cutaneous form is more and more described during HIV infection (Durant, 1998). The diagnosis of LC is evoked clinically, confirmation is based on the detection of the parasite. The direct examination on the smear or the colored puncture with the MGG seems to be the best examination for the diagnosis because economic, easy, fast and without danger. However, it lacks sensitivity. Special Environment (NNN) culture improves the sensitivity of parasitological examination by 16% (Belhadej 2005, Grevlink 2003)]. Pathological examination also contributes to the diagnosis. The enzymatic identification of species is a reference technique, reserved for specialized laboratories, as well as for PCR, the results of which seem very promising (98% sensitivity versus 80% with conventional diagnostic means) (Chergui, 2003; Matsumoto, 1999).
