Penetration of the oral mucosa by parasite-like sperm bags of squid: a case report in a Korean woman

J Parasitol. 2012 Feb;98(1):222-3. doi: 10.1645/GE-2827.1. Epub 2011 Aug 11.


We report a case of oral stings by spermatophores of the squid Todarodes pacificus . A 63-yr-old Korean woman experienced severe pain in her oral cavity immediately after eating a portion of parboiled squid along with its internal organs. She did not swallow the portion, but spat it out immediately. She complained of a pricking and foreign-body sensation in the oral cavity. Twelve small, white spindle-shaped, bug-like organisms stuck in the mucous membrane of the tongue, cheek, and gingiva were completely removed, along with the affected mucosa. On the basis of their morphology and the presence of the sperm bag, the foreign bodies were identified as squid spermatophores.
