Orofacial manifestations of mucocutaneous leishmaniasis: a case series from Brazil.

The dental surgeon plays a fundamental role in the early diagnosis of oral leishmaniasis, since oral mucosa may be the primary site of the disease manifestation. This study reports seven clinical cases of orofacial mucocutaneous leishmaniasis. All had mucocutaneous leishmaniasis with oropharyngeal involvement confirmed by laboratory tests. Five out of the seven cases were males, and in four cases, patients had associated comorbidities. Late diagnosis was observed, resulting in treatment delay and increased hospitalization stay. One patient had severe psychological consequences due to facial deformity. The lack of differential diagnosis due the great variability of clinical presentation of the lesions and frequent unspecific histopathology represent a challenge for the dental surgeon. In two reported cases, there were unspecific biopsy results. The multidisciplinary approach plays an important role in orofacial leishmaniasis diagnosis and treatment. Leishmaniasis should be investigated in case of atypical and persistent lesions in patients from endemic regions. This recommendation may avoid diagnosis delays and decrease dissemination of the disease.
