Species: Lagochilascariasis minor
Eggs: 50-90 microns with thick shells and a coarse, pitted surface

Infection occurs when a person ingests raw or undercooked feline meat that contains L3 larvae.
Autoinfection can occur once the host is infected.
The main clinical finding is a nodular lesion in the head and neck region, including:
(1) cervical region
(3) middle ear
A nodule may show a cutaneous fistula tract from which worms may be discharged.
The eosinophil count is often normal.
Relapse can occur if therapy is stopped as soon as nodules disappear. A patient should be treated for at least one month after a cliinical cure has been achieved.
