Primary retroperitoneal seminomas account for approximately 2% of all seminomas. Differentiating the primary retroperitoneal tumor from a metastatic tumor with an occult testicular primary remains difficult despite the availability of ultrasonic examination. We present a case of primary retroperitoneal seminoma with ultrasonically demonstrated abnormalities in both testes. The patient underwent a unilateral orchiectomy and ultrasound-guided biopsy of the opposite testis. All surgical specimens were negative for testis cancer. Controversial issues in the diagnosis and treatment of primary retroperitoneal germ cell tumors are discussed.

Symptomatic abdominal aortic aneurysms carry significant mortality risk. This is supplemented by the Royal College of Emergency Medicine guidelines which suggest imaging for patients 50 years of age or older presenting with unexplained abdominal, flank, or back pain. This study aimed to evaluate the prevalence and mortality rates of patients with symptomatic abdominal aortic aneurysms in a high-risk population and to assess scanning rates in the accident and emergency department.

Purpose: To assess the association between neoadjuvant therapy and overall survival (OS) in patients with left-sided resectable pancreatic cancer (RPC) compared to upfront surgery.
Background: Left-sided pancreatic cancer is associated with worse OS compared to right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not effective in patients with RPC, current randomized trials included mostly patients with right-sided RPC.

Introduction And Importance: Retroperitoneal schwannomas are extremely rare, benign tumors originating from Schwann cells in peripheral nerve sheaths, with few reported cases. Their deep location and nonspecific symptoms make preoperative diagnosis challenging, often requiring imaging and surgical resection for confirmation. This case highlights an uncommon presentation of retroperitoneal schwannoma in a young patient, emphasizing its rarity.

Introduction: Neuroblastoma is an embryonic tumor of the peripheral sympathetic nervous system. It is the most common extracranial solid tumor of childhood and accounts for up to 15% of all pediatric cancer fatalities. The manifestation of neuroblastoma is variable depending on the location of the tumor and the presence or absence of paraneoplastic syndromes.
