Abstract

A 6-year-old male Rottweiler dog presented with a marked weight loss combined with abdominal pain and diarrhea over 3 month. Hematology revealed lymphocytosis, neutrophilia and eosinophilia. Abdominal ultrasound revealed a heteroechoic mid-abdominal mass with a focal hypoechoic area measuring 6.0 x 5.0 cm but with a confusing origin. The mass was resected and intestinal anastomosis was performed after celiotomy. Histopathology of the mass demonstrated massive lympho-proliferative lesions were diagnosed as low grade lymphoma with diffuse small lymphocytic (DSL-plasmacytoid) pattern. The dog was recovered and a one-month ultra sonography follow-up showed no-recurrence.

Highlights

GI mesenchymal tumors are mainly comprised of a series of spindle cell tumors, including GI stromal tumors, leiomyomas, lymphomas, schwannomas, inflammatory fibroid polyps, fibromatoses and leiomyosarcomas (Greenlee et al, 1990; Teske et al, 1994; Davis et al, 2000; Miettinen and Lasota, 2001)
The mass including the involved part of the intestine was resected with subsequent intestinal anastomosis
With respect to the patient’s presented reported signs, there were crampy abdominal pain associated with anorexia, bloating, diarrhea and weight loss

Summary

Introduction

GI mesenchymal tumors are mainly comprised of a series of spindle cell tumors, including GI stromal tumors, leiomyomas, lymphomas, schwannomas, inflammatory fibroid polyps, fibromatoses and leiomyosarcomas (Greenlee et al, 1990; Teske et al, 1994; Davis et al, 2000; Miettinen and Lasota, 2001). GISTs smaller than 3 cm are generally considered benign tumors (Bonsaing et al, 2007) and GISTs larger than 3-5 cm, with mitotic counts greater than 2/10 high power field or that involved more layers are generally considered high-risk tumors for malignancy ( Giuly et al, 2003; Miettinen et al, 2000).The presented case is reported due to its rare occurrence. Abdominal ultrasonography detected a heteroechoic midabdominal mass with a focal hypoechoic area measuring 6.0 x 5.0 cm but with confusing origin (fig.1).The remainder of the intestinal tract and viscera were unremarkable.
