Pulmonary paragonimiasis diagnosed by fine-needle aspiration biopsy

Neda Zarrin-Khameh et al. J Clin Microbiol. 2008 Jun.

Abstract

We report a case of paragonimiasis involving a 12-year-old Latin American boy. The diagnosis was made by fine-needle aspiration biopsy of a pulmonary nodule. Identification of the species by morphometric analysis of the eggs indicated that the infection was caused by Paragonimus mexicanus.

Paragonimus egg, composite photograph. The left panel shows an egg from the biopsy using fine-needle aspiration, where we see the characteristic thickened shell and slightly flattened end (Papanicolaou stain; magnification, ×400). The right side illustrates the birefringent Paragonimus egg; this characteristic helps differentiate this parasitic egg from Schistosoma japonicum (Papanicolaou stain; magnification, ×400).
