RESUMEN
INTRODUCTION: Retroperitoneal cysts are uncommon, with an estimated incidence of 1/5750 to 1/250,000. CASE PRESENTATION: A male patient was admitted with an abdominal pain, jaundice and fever. Clinical examination and investigations confirmed an idiopathic benign retroperitoneal cyst. He underwent surgery and was discharged after making good recovery. CONCLUSION: Retroperitoneal cysts are very rare, and most of the time they are discovered incidentally. Patients may be asymptomatic or present with abdominal pain, referred pain to the legs or weight loss. Imaging may help diagnose these lesions, but surgery is the keystone in confirming the diagnosis. This case is very rare and very educational as it highlights an unusual presentation of a benign retroperitoneal cyst. In our patient, the course of the disease was unique as the patient presented with jaundice.
RESUMEN
BACKGROUND: Cystic neoplasms of the pancreas comprise 10%-15% of pancreatic cystic lesions, with the serous cystadenoms being the commonest. The association of exocrine and endocrine tumours of the pancreas unrelated to Von Hipple Lindau disease is very rare. Very few cases have been reported in the literature. We present another case of both these tumours in one patient. CASE PRESENTATION: A female patient was seen in the surgical clinic for a pain in the right groin. Clinical examination and investigations confirmed a diagnosis of combined endocrine and exocrine tumours of the pancreas. She underwent surgery and is under regular follow-up in the surgical clinic. CONCLUSION: Biphasic differentiation of pancreatic stem cell during embryological development could happen and may result in combined endocrine and exocrine tumours of the pancreas. Imaging studies are excellent in diagnosing theses lesions. Surgery has a central role and could be curative.
