Primary prostate lymphoma: a rare presentation of lower urinary tract symptoms in young aged patient.

Primary prostatic lymphoma is a rare prostate malignancy that accounts for 0.09% of prostate cancer and 0.1% of lymphoma. Clinical misdiagnosis is common as majority of cases present with non-specific urinary symptoms like other prostatic diseases or prostatic cancer. Early diagnosis is of significant paramount as prognosis is dependent on histological type and tumour staging at the time of diagnosis. Urologists should remain aware of rare histological types of prostate cancer as delayed diagnosis of primary prostate lymphoma can be detrimental and lead to advanced disease causing serious sequelae i.e renal failure in addition to the primary pathology.

Idiopathic pseudoaneurysmal omental bleeding, a rare cause of life-threatening acute abdomen.

Mesenteric aneurysms and their complications can be a life-threatening presentation of acute abdomen to the emergency department. The majority of mesenteric artery aneurysms are incidentally detected on imaging investigations and are asymptomatic. Symptomatic mesenteric aneurysms manifest as hemoperitoneum or abdominal pain. In addition, treatment of symptomatic aneurysms is delayed due to the infrequent consideration of the diagnosis in patients presenting with abdominal pain. Timely and accurate diagnosis is of paramount importance as any delay in definitive surgical management can lead to increased patient's mortality and morbidity with up to 25% of mesenteric aneurysms may be complicated by rupture.
