RESUMEN

We tried to determine the epidemiology and species of human dirofilariasis observed at two tertiary care hospitals in Kerala. We searched the hospital database to identify cases of dirofilariosis from January 2005 to March 2020. Along with human isolates, one dog Dirofilaria isolate was also subjected to PCR and sequencing of pan filarial primers cytochrome oxidase subunits 1 and 12S rDNA. We documented 78 cases of human dirofilariosis. The orbit, eyelid, and conjunctiva were the most commonly affected sites. Molecular characterization identified one dog and five human isolates as Candidatus Dirofilaria Hongkongensis. A rare case of subconjunctival infestation by B. malayi was also documented. Human dirofilariosis is a public health problem in the state of Kerala in India, and it is mostly caused by Candidatus Dirofilaria Hongkongensis. We propose that all diroifilaria isolates are subjected to sequencing for identification.

RESUMEN

Germ cell tumor can affect extragonadal sites. Teratoma is a well-recognized extragonadal tumor in the orbit. Primary yolk sac tumor (YST) or endodermal sinus tumor of orbit is rare and only few cases have been reported in the literature. Its clinical presentation may mimic many common pediatric orbital conditions, and delay in diagnosis affects ocular morbidity and mortality. In the past orbital YST has been treated with multimodal therapy including surgery, systemic chemotherapy, and radiotherapy. Herein we describe a case of primary orbital YST and reviewed the literature for similar cases. The review aims to describe the clinical presentation, imaging features, histopathological characteristics, and management of orbital YST.
