[3][4][5] Visceral linguatuliasis has been described in several countries in Europe, the middle East, North Africa, and almost all of the Americas.

“…Humans may act as an intermediate or accidental definitive host, manifesting the nasopharyngeal or visceral form, with the latter being more frequently described. [1][2][3] Nasopharyngeal linguatuliasis, or Halzoun-Marrara syndrome, which has been described in Lebanon, Turkey, Greece (Halzoun) and Sudan (Marrara), is produced by ingestion of nymphs or third-instar larvae together with food such as raw or semi-raw sheep liver or lymph nodes. The symptoms are varied and include an irritated and sore throat, edema, and congestion that may extend to the larynx, Eustachian tubes, conjunctiva, nose, and lips.…”

Abstract. Linguatula serrata is a pentastomid, a cosmopolitan parasite belonging to the Phylum Pentastomida. Humans may act as an intermediate or accidental definitive host of this parasite, manifesting the nasopharyngeal or visceral form, with the latter having been described more frequently. The occurrence of ocular linguatuliasis is extremely rare, but it has been reported in the United States and Israel. The objective of the present paper was to report the first case of ocular linguatuliasis in Ecuador and to extend the morphologic study of L. serrata by morphometric analysis. The patient studied was a 34-year old woman from Guayaquil, Ecuador who complained of ocular pain with conjunctivitis and visual difficulties of two-months duration. Biomicroscopic examination revealed a mobile body in the anterior chamber of the eye. The mobile body was surgically removed. The specimen was fixed in alcohol, cleared using the technique of Loos, stained with acetic carmine, and mounted on balsam between a slide and a coverslip. It was observed with stereoscopic and common light microscopes in combination with an automatic system for image analysis and processing. The morphologic and morphometric characteristics corresponded to the third-instar larval form of L. serrata. To our knowledge, ocular linguatuliasis has not been previously described in South America, with this being the first report for Ecuador and South America. The present study shows that computer morphometry can adequately contribute both to the morphologic study and to the systematic classification of Pentastomids, and L. serrata in particular.

“…Pentastomids have been reported in humans in tropical Africa and Asia, but the parasite in captive animals is of no public health significance [290,692,749]. Infection of humans can occur only through the ingestion of eggs passed in the feces or in the saliva of the definitive host [290].…”

Necropsies were performed on 285 consecutively unclaimed Orang Asli bodies from Gombak Orang Asli Hospital during an eight‐year period from May 1967 to April 1975. Of the 25 malignant neoplasms, hepatocellular carcinoma was by far the commonest (36%). The nine patients with this neoplasm had coexistant macronodular cirrhosis. There were 20 cases of cirrhosis; 45% of these had coexistant hepatocellular carcinoma. The 53,000 Orang Aslis living in West Malaysia comprise three tribes, the Negrito, Senoi, and Melayu Asli (Proto Malays). The Senoi appear to have a high predilection for liver cancer, all our nine cases occurring in this group. These aboriginal people live in the jungles where they practice shifting cultivation and maintain their own dietary and social customs. Detailed studies of their dietary habits may provide a clue to the etiology of liver cancer in these people.
