Nasal polyps in dogs are space-occupying soft-tissue masses that have been encountered concurrently with intranasal neoplasia in surgical biopsy specimens. The proportion of nasal polyp co-occurrence with primary nasal tumors was examined, and follow-up biopsies on dogs initially diagnosed with nasal polyp were reviewed. Histologic sections from 321 cases of intranasal neoplasia and 50 cases of nasal polyp from 2004 to 2017 were reviewed. Of the 321 cases of intranasal neoplasia, 51 (16%) had concurrent nasal polyps, and most of these (47/51) had intranasal carcinoma. Twenty-five of the 50 dogs with a primary diagnosis of nasal polyp were rebiopsied, and the diagnoses in these subsequent biopsies were nasal polyp in 15, malignant neoplasm in 9, and intranasal nematode in 1. Nasal polyps occurred frequently in conjunction with nasal carcinoma. In dogs with a diagnosis of nasal polyp, repeat biopsy to reveal possible neoplasia is warranted.

鼻息肉和犬鼻腔肿瘤共存。

狗鼻息肉是占用空间的软组织肿块，在手术活检标本中与鼻内瘤形成同时发生。检查鼻息肉与原发性鼻肿瘤共存的比例，并对最初诊断为鼻息肉的狗进行活检。回顾了2004年至2017年的321例鼻内瘤变和50例鼻息肉的组织学切片。在321例鼻内瘤变中，有51例（16％）并发鼻息肉，其中大多数（47/51）患有鼻内癌。对50例初步诊断为鼻息肉的狗中的25例进行了活检，随后这些活检的诊断为15例鼻息肉，9例恶性肿瘤和1例鼻内线虫。鼻息肉常与鼻癌一起发生。 。
