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.
