Background: An unusual case of visceral pentastomiasis in a male adult long-tailed macaque imported from China is reported.
Methods: The monkey was part of a toxicologic study. A massive accumulation of C-shaped parasites in various visceral organs was found post-mortem.
Results: Based on the morphology of the nymphs, pentastomiasis was diagnosed etiopathologically. The pentastome genus and species was identified as Armillifer agkistrodontis by PCR and respective sequencing.
Conclusion: Molecular diagnostic methods are necessary tools to determine the exact species involved.

We report a case of an 80-year-old symptomatic female with severe visceral infestation who presented with complaints of progressively worsening colicky abdominal pain with associated constipation and mild abdominal distension. Imaging workup demonstrated unique radiological features of the parasite including multiple curvilinear opacities, measuring approximately 3 to 6 mm in length, scattered in the lung fields, abdomen, pelvis, and inguinal region. Histologic examination of inguinal biopsies revealed enlarged lymph nodes containing several parasitic pseudocysts.

Larval stages of pentastomids were collected from different organs of small mammals from the Peruvian Amazon. These parasitized mammals included: a western Amazonian oryzomys (Hylaeamys perenensis), an elegant oryzomys (Euryoryzomys nitidus), a lowland paca (Cuniculus paca), two kinkajous (Potos flavus), two silvery woolly monkeys (Lagothrix poeppigii) and a brown-mantled tamarin (Leontocebus fuscicollis). Pentastomids were found in the mesentery and parenchyma of the liver and lungs of these animals.

In January 2016, a 20-year-old female oriental small-clawed otter (Aonyx cinereus) from Night Safari in Singapore was euthanized and diagnosed with a thyroid gland carcinoma. Postmortem examination and histology also revealed metastasis to the regional lymph nodes and severe visceral pentastomiasis. Grossly, the lymph nodes were infested, and encapsulation was observed on the visceral serosal surface.

We describe a case of visceral pentastomiasis discovered during inguinoscrotal hernia surgery for a man from Benin, Africa. Because surgical removal of nymphs is needed for symptomatic patients only, this patient's asymptomatic pentastomiasis was not treated and he recovered from surgery uneventfully.
