A 65-year-old woman was referred to the Fajr Health Center. The chief complaint was a lip lesion that began 2 months prior as a slowly enlarging nodule. Patient reported that the lesion began as a small soft mass, which ulcerated later. Clinical examination showed a necrotic ulcer of the left lower lip vermillion. The lip was erythematous and edematous from midline to the left commissure mediolaterally (Fig. ). With suspicion of basal cell carcinoma and squamous cell carcinoma, skin scraping, culture, and PCR were accomplished. Touch impression smears and culture were positive and the parasite was characterized by PCR as L. tropica.
