Lebanon, an underendemic area for cutaneous leishmania (CL), is suffering from a CL outbreak brought by the massive population influx from endemic Syria. CL affects mainly exposed areas; therefore, the head and neck (HN) region is highly susceptible. Individuals diagnosed and speciated with CL (n = 168) using molecular and microscopic analysis on punch biopsy/scrapings were studied. Clinical data, parasitic index (PI) and Ridley's Pattern (RP) were recorded. The HN was divided into 11 anatomic locations. Of 168 patients, 96 patients (57.1 %) had HN involvement and 72 (42.9 %) had no HN involvement. Lesions from the HN were significantly more common in younger patients and were more prone for ulceration, had larger size, higher PI and more advanced RP (p < 0.05). There was no difference in the anatomic distribution of lesions among age groups and genders in the HN group. The cheek area was the most HN involved location. Lesions were less commonly encountered in the veiled area in women. In the community we studied, HN is commonly involved by CL. Lesions with HN involvement were encountered more in pediatric age group and showed more extensive features.
