[A case of concomitant hepatic lesion in a child with cystic hydatid disease and Arthropoda larva (nymph)].

A 15-year-old patient living in Bashkortostan was admitted as having a diagnosis of hydatid cyst of the left hepatic lobe for surgical treatment. He had the following concomitant diseases: neurodermatitis, bronchial asthma, and acute respiratory disease. After surgery (laparoscopic echinococcectomy), a portion was taken from the parent vesicle wall for a histological study. The parasite was detected on the inner membrane surface. It is suggested that this is a Pentastoma sp. (Arthropoda, Maxillopoda, Pentastomida, and Cephalobaenida). Thus, the observed patient has a combined hepatic invasion with Echinococcus and Pentastoma).
