Non-pancreatic pseudo cyst of oral cavity-case report

INTRODUCTION AND IMPORTANCE: Cyst is commonly found in oral and maxillofacial region, but non-pancreatic pseudo cyst in this region is quite rare. None of the such cases have been reported so far. Presented here is the case of non-pancreatic pseudo cyst in the right cheek. A description and management of this pathology through open surgery is given, while preserving the anatomy of the cheek. CASE PRESENTATION: The authors report a non-pancreatic pseudo cyst of the right cheek in a 4 years old boy. His parents noticed swelling over right cheek which slowly increases in size without any other associated symptoms. The swelling was firm, non-tender, nonfluctuant, non-pulsatile, margin was distinct, overlying mucosa was normal in colour, aspiration was negative, 3x2x1 cc in size. The surgical excision of the tumour was performed through an intraoral approach under general anaesthesia. Intraoperatively we found clotted blood confined within fibrous capsule. During one year postoperative follow-up there was no sign of recurrence. CLINICAL DISCUSSION: Pancreatic pseudocysts are benign soft tissue lesion occurring most commonly in pancreas. They are rarely encountered in the soft tissue of Oral and Maxillofacial region. It is the first case of non-pancreatic pseudocyst found in soft tissue of oral and maxillofacial region. The etiopathogenesis of these pseudocysts is not known yet. It may be considered as soft tissue counterpart of Aneurysmal Bone Cyst (ABC). CONCLUSION: Non pancreatic pseudo cysts may form in soft tissue of oral and maxillofacial region.
