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.
A 62-year-old male patient, rural worker, smoker, and chronic alcohol user, HIV negative, was referred to the stomatology clinic with upper lip and upper alveolar ridge lesions present for 2 months. During anamnesis, sudden weight loss was reported. Medical history recorded no other important data. Extraoral physical examination showed a cutaneous lesion in the left thigh region [] and along with ulcerated lesions of the nasal mucosa. Cervical lymphadenopathy was undetected on palpation.\nPhysical intraoral examination revealed ulcerated and irregular lesions in the mucosa of upper alveolar ridge and palate [Figure and ]. An incisional biopsy was performed under local anesthesia considering a differential diagnosis with paracoccidioidomycosis, tuberculosis and leukemia.\nSerologies for histoplasmosis and toxoplasmosis were subsequently requested, both resulting in non-reactive antibodies. Therefore, mucocutaneous leishmaniasis was suspected. Histopathologic data showed a non-specific chronic inflammatory process. Immunohistochemistry procedures revealed cells positive for CD68 and Leishmania antigen [Figure and ]. In addition, the positivity of the IDRM test proved the hypothesis. Treatment, therapeutic response and follow-up of this patient were similar to those cited for the previous patient.
