Case report: unusual presentation of Fasciolopsis buski in a Viet Namese child

Abstract

A Vietnamese child presented with a history of abdominal pain. Shortly afterwards, he vomited eight live trematode flukes that were collected and morphologically identified as Fasciolopsis buski. The identification was confirmed by DNA analysis. Adult worms of F. buski from humans are very rarely seen except at autopsy, and this is the first such report from Vietnam.

Foodborne Intestinal Flukes in Southeast Asia

“…Two sequences corresponding to the 18S rRNA gene are deposited in Genbank [142]. Using this DNA sequence, fluke specimens vomited by a child was confirmed as F. buski [290]. Species-specific ITS sequences of ribosomal DNA were described, and the sequences of eggs and adults were identical in length and composition [291].…”

Live Fasciolopsis buski vomited out by a boy

“…Adult worms are very rarely seen, except in autopsy, but there is only one case report of live adult worms being vomited out and another report of live adult worms coming out through an ileostomy opening. [5,6] To the best our knowledge, there are no reports of fasciolopsiasis from this region. This case raises the possibility that there may be more number of unidentified cases in this region.…”

Fasciolopsis buski Vomited Out by a Child; The First Case Reported from Nepal

“…So it is high chance that the child may have got infection from the water he drank from the pond as no other history which might involve the risk of getting infection by Fasciolopsis buski could be elucidated. Live adult worms of this parasite are very rarely seen in humans except in autopsy [5]. There are two more reports of live adult worms being vomited out [1,5].…”

“…Live adult worms of this parasite are very rarely seen in humans except in autopsy [5]. There are two more reports of live adult worms being vomited out [1,5]. Other cases of live adult worms causing different clinical conditions are reported by Cao et al [2], Mahajan et al [4] and Lee et al [6].…”
