A Rare Case of True Pancreatic Cyst.

Pancreatic cysts can be true or pseudocysts. True pancreatic cysts in children are rare clinical entities. We present a 23-month-old boy with a cystic lesion in the distal body and tail of the pancreas which on histopathology was found to be a rare true congenital simple cyst of the pancreas.

BACKGROUND: True congenital pancreatic cysts are a rare pathological process reported within feline and human literature. To date there has been no documented case of a true congenital cyst affecting a canine patient. The objective of this case report is to document the clinical findings, diagnostic investigations, surgical treatment, histopathological diagnosis and long-term outcome of a dog with a true pancreatic cyst. CASE PRESENTATION: A 5-month-old crossbreed dog was presented with a six-week history of abdominal pain, apparent bilateral pelvic limb weakness, reluctance to walk and intermittent vomiting and diarrhoea. An abdominal ultrasound examination performed by the dog's primary care veterinarian identified a large intra-abdominal structure of unclear origin. A computed tomographic examination identified a large ovoid structure measuring 156 mm in length, 95 mm in height and 89 mm in width and apparently originating from the left limb of the pancreas. An exploratory coeliotomy was performed and a partial pancreatectomy was performed to allow complete removal of the cystic structure. Histopathological analysis of sections of the wall of the large fluid-filled cyst identified a thick fibromuscular wall lined by a well regimented hyperplastic tall columnar epithelium with basally located round to ovoid nuclei featuring fine chromatin stippling and abundant apically located and surface mucin, concurrent with a true congenital pancreatic cyst. A long-term follow-up of twenty-nine months identified no clinical signs of recurrence. CONCLUSION: A partial pancreatectomy and en bloc excision of a true pancreatic cyst provided an excellent long-term outcome in a dog.

Congenital Cyst of the Pancreas: A Case Report and Review of Literature.

This is a case of a newborn female with congenital pancreatic cysts discovered incidentally. The 5-week-old infant had multiple abdominal cysts originating from the pancreas. When the radiologist catheter placement failed to alleviate the symptoms, the infant underwent laparoscopic excision. The lesion, however, recurred 11 months after the first excision, leading to a second surgical procedure including excision and marsupialization. A review of the literature revealed that this is a rare condition. Herein, we discuss the characteristics of the case, including medical imaging, drainage catheter placement, surgical treatment, pathological findings, and follow-up. Differential diagnoses, clinical presentations, treatment options, and patient outcomes are also discussed. Although rare, congenital pancreatic cyst should be considered in the differential diagnosis of an infant with cystic lesion of the pancreas.
