Enterectomy in the treatment of obstructive neuroendocrine carcinoid in a dog: case report

Abstract

Carcinoids in dogs are rare neoplasms of the diffuse neuroendocrine cell system. The term neuroendocrine tumor has been proposed and the clinical manifestation is related to the location. Despite the low rate of growth and metastasis, such neoplasms are often malignant and must undergo surgical resection. When this is done properly, the outcome is usually satisfactory. The objective of this study was to describe a case of carcinoid in a 10-year-old female with tenesmus and presence of fecaloma. The patient was received at a private veterinary clinic and, after clinical consultation and imaging examinations, she was submitted to the enterotomy and removal of fecaloma in the descending colon. The obstruction of the intestinal flow was resulting from a neoplastic mass in a pre-pubic region, also resected and forwarded for analysis. The histopathological revealed neuroendocrine carcinoid and the dog was followed for 60 days after the procedure, without signs of recurred or metastasis. Therefore, it is understood that neuroendocrine carcinoids should be considered as a cause of tenesmus and constipation in dogs, especially in the elderly, and the prognosis is favorable when patients undergo the surgical procedure with adequate resection of the tumor.
