“…9,10 Apart from this, the retention of vegetable remnants in the bronchial tree may be responsible for the presence of certain symptoms of pulmonary superinfection. 11,12 Due to the morphologic characteristics of the vegetable tissues in the pulmonary parenchyma, some elements may originate parasite-like structures in histologic sections, necessitating a differential diagnosis with pulmonary parasitosis 13 and certain arthropods, such as Armillifer armillatus, and worms, such as Ascaris lumbricoides.In other types of samples, such as cytologic smears, the presence of vegetable elements may be a chance finding, generally related with contamination of the sample, 14 or indeed may be the cause of a specific process. 15 The recognition of uncommon morphologic structures, and their comparison with others already known, in both histologic sections and cellular smears, may be useful when it comes to establishing a diagnosis, avoiding confusion with other pathogenic elements.…”
