Lagochilascariasis in a 54-year-old male hunter in Brazil. A) Nodular tumorous lesion on cervical region caused by L. minor infection. B) Biopsy of nodular lesion showing granuloma and larvae of L. minor nematode. Hematoxylin and eosin staining. Original magnification ×50. C) Optic microscopy shows the ejaculatory duct with spicule and lateral alae of L. minor. The ratio of ejaculatory duct length to spicule length of the worms is ≈2. Original magnification ×50.
