The condition was unresponsive to antibiotic therapy, and previous surgical excision had been unsuccessful in 3 dogs. None of the dogs had any other congenital defects, and all dogs responded to complete surgical excision of the tract and cyst. On histopathologic examination of excised tissue, there were adnexal structures along a tract lined with stratified squamous epithelium, consistent with a developmental abnormality of ectodermal tissue.<\/jats:p><jats:p><jats:bold>Conclusions\u2014<\/jats:bold> The lesions were diagnosed as nasal dermoid sinus cysts, similar to the congenital condition described in humans. Nasal dermoid sinus cysts are rare developmental defects related to abnormal development of the pre\u2010nasal space and may extend into the cranial vault causing cerebral abscesses or recurrent meningitis. Complete surgical excision has a good prognosis.<\/jats:p><jats:p><jats:bold>Clinical relevance\u2014<\/jats:bold> This is a new condition that should be added to the surgical differential diagnosis for a discharging sinus over the external nares in dogs.<\/jats:p>","DOI":"10.1053\/jvet.2002.33597","type":"journal-article","created":{"date-parts":[[2002,8,25]],"date-time":"2002-08-25T03:46:10Z","timestamp":1030247170000},"page":"303-308","source":"Crossref","is-referenced-by-count":25,"title":["Nasal
