ABSTRACT
Cutaneous Larva migrans is a very common disease in tropical regions. In the oral mucosa, the infection occurs in the same way as in the skin, but it is rarer. This report describes two cases of Larva migrans in the oral mucosa. The first case was in a 27-year-old woman who presented an erythematous plaque located on the buccal mucosa, extending to a posterior direction, following a linear pattern, to other areas of the mouth. After incisional biopsy of the anterior-most portion of the lesion, morphological details obtained in multiple examined sections suggested Necator or Ancylostoma braziliense larvae as the cause of infection. The second case was in a 35-year-old male who presented a fusiform erythematous plaque in the palatal mucosa. This area was removed and submitted to microscopic examination under a presumptive diagnosis of "parasite migratory stomatitis". The histological characteristics were suggestive of a larva pathway. In both cases the lesion disappeared after biopsy and the patients were symptom-free.
RESUMO
Larva migrans cutânea é uma doença muito comum em regiões tropicais. Na mucosa oral, a infecção ocorre da mesma forma como na pele, mas é raro. Este relato descreve dois casos de Larva migrans na mucosa oral. O primeiro caso foi de uma mulher de 27 anos de idade, que apresentou uma placa eritematosa localizada na mucosa julgal, estendendo-se posteriormente, em conformação linear, para outras áreas da boca. Após biópsia incisional da porção mais anterior da lesão, detalhes morfológicos obtidos em múltiplos cortes examinados sugeriram Necator ou larvas de Ancylostoma braziliense como a causa da infecção. O segundo caso foi de um homem de 35 anos de idade que apresentou uma placa fusiformes eritematosas na mucosa palatina. Esta área foi removida e submetida a exame microscópico, com diagnóstico presuntivo de "estomatite migratória por parasita". As características histológicas foram sugestivas de trajeto de larva. Em ambos os casos a lesão desapareceu após a biópsia e os pacientes estavam assintomáticos.
