ABSTRACT
AIM:
The objective of this study was to describe and characterize the postmortem and histopathological findings of putative esophageal chondrosarcoma associated with Spirocerca lupi. MATERIALS ANDMETHODS:
Spirocerca-associated esophageal nodules were collected from 54 dogs at postmortem examination and were stained with hematoxylin and eosin. Of the cases examined, 15 were selected randomly for further investigation, of which 11 were classified as non-neoplastic nodules while 4 had changes reflecting a neoplastic process.RESULTS:
In all four neoplastic cases, the wall of the esophageal nodules contained islands and nests of highly proliferative atypical chondroblasts within a cartilaginous matrix. However, there was no statistically significant association between gender (p=0.228), age (p=0.568), and breeds (p>0.05) with the occurrence of spirocercosis. Moreover, all esophageal nodules identified were located near the caudal segment, and their diameters ranged from 1 to 6 cm (4.7±1.5 cm). A number of worms in each nodule varied from 5 to 25 (11.3±5).CONCLUSION:
Histopathology and cytology revealed that the wall of the esophageal nodules contained islands and nests of highly proliferative atypical chondroblasts within a cartilaginous matrix, a rare finding, and clinical challenge in spirocercosis.
