Summary: Two cases of lagochilascariasis minor in domestic cats from Costa Rica within a period of two months are recorded for the first time in Central America. Clinical findings included purulent discharge and a tumor in the left ear in one of the cats, whereas the other cat had an ulcerated cervical lesion. Both patients underwent surgical procedures during which nematode worms were collected and analyzed. The collected nematodes were identified using a combination of morphological and molecular assays, which revealed a 99.1% similarity in the cytochrome oxidase subunit 1 with L. minor from Mexico. The lack of information on this parasitosis, as well as the enormous harm it does to animal and human hosts, highlights the need for more research and awareness in Costa Rica and Central America. Furthermore, the unexpected occurrence of these instances in the same location emphasizes the imminent zoonotic risk to humans and the active circulation of the parasite.
