De Garengeot Hernia in a Male Patient: Case Report of an Incarcerated Appendix Managed by a Hybrid Approach

Abdul Raheem Malik, et al.

INTRODUCTION: De Garengeot hernia is a rare condition in which the appendix is trapped within a femoral hernia. It accounts for less than 1% of femoral hernia cases and is more common in females, making its occurrence in males particularly unusual. Diagnosis is challenging because symptoms and laboratory findings are often nonspecific, and no standardized surgical protocol exists.

A Rare Case of Adenosquamous Carcinoma Arising from Intraductal Papillary Neoplasm of the Bile Duct

Akifumi Kawahito, et al.

INTRODUCTION: Intraductal papillary neoplasm of the bile duct (IPNB) is an uncommon biliary tumor that often exhibits invasive growth but generally shows a more favorable prognosis than conventional cholangiocarcinoma. In contrast, adenosquamous carcinoma (ASC) of the bile duct is rare and associated with markedly poor outcomes. We report an extremely rare case of ASC arising from IPNB in the intrapancreatic bile duct.

Hepatic Compartment Syndrome Induced by Subcapsular Hematoma following Percutaneous Transhepatic Gallbladder Drainage: A Case Report

Reina Miyazaki, et al.

INTRODUCTION: Hepatic compartment syndrome (HCS) is a rare but potentially fatal condition caused by acute elevation of intrahepatic pressure, most often secondary to a subcapsular hematoma. Iatrogenic cases, particularly after percutaneous hepatobiliary interventions, have been only sporadically reported. We describe HCS following percutaneous transhepatic gallbladder drainage (PTGBD) complicated by a subcapsular hepatic hematoma.

Rare Extrahepatic Metastasis of Hepatocellular Carcinoma to the Left Triangular Ligament: A Case Report

Ayumi Tsuda, et al.

INTRODUCTION: The left triangular ligament is an uncommon site of heterotopic liver tissue, from which ectopic hepatocellular carcinoma (HCC) may arise. In contrast, extrahepatic metastasis from an intrahepatic primary HCC to the triangular ligament appears to be extremely rare. To the best of our knowledge, within the scope of our structured search of the English-language literature (PubMed and Web of Science), we did not identify a pathologically confirmed report of an isolated metastasis to the left triangular ligament from an orthotopic HCC. We report a case of isolated HCC metastasis to the left triangular ligament discovered incidentally during laparoscopic hepatectomy, which posed a differential diagnostic challenge between ectopic HCC and extrahepatic metastasis.

A Case Report of Robotic Salvage Tumor Resection with Combined Resection of the Internal Iliac Vessels and Ureter for Lateral Local Recurrence after Lateral Lymph Node Dissection for Rectal Cancer

Riki Ohno, et al.

INTRODUCTION: Lateral local recurrence (LLR) is a recognized pattern of local recurrence in patients with low rectal cancer (LRC) following curative resection, and salvage surgery for LLR is technically challenging. Recent studies have reported the feasibility of robotic lateral lymph node dissection (LLND) in patients with LRC; however, data regarding the safety and usefulness of robotic salvage surgery for LLR after LLND remain limited. Herein, we report a case of robotic salvage tumor resection with combined resection of the internal iliac vessels (IIVs) and ureter for LLR following LLND.

Laparoscopic Repair of an Incarcerated Parahiatal Hernia with Gastric Necrosis: A Rare Case Report

Kazuyoshi Mitta, et al.

INTRODUCTION: Primary parahiatal hernias are rare in adults. We report the case of a young woman with a parahiatal hernia without obvious predisposing factors that resulted in gastric fundus necrosis.

Staged Surgical and Endovascular Management of Parkes–Weber Syndrome to Preserve Limb Function: A Case Report

Kyokei Fuchizawa, et al.

INTRODUCTION: Parkes–Weber Syndrome (PWS) is a rare congenital vascular disorder of unknown etiology for which no established curative treatments currently exist. High-flow arteriovenous malformations (AVMs) in PWS can lead to severe complications, including the need for major limb amputation.

Laparoscopic Hepatectomy for Hepatic Inflammatory Myofibroblastic Tumor: A Case Report

Yuta Hiura, et al.

INTRODUCTION: Inflammatory myofibroblastic tumors (IMTs) are neoplasms composed of spindle-shaped myofibroblasts along with inflammatory infiltrate, and possess malignant potential. Primary hepatic IMTs (HIMTs) are relatively uncommon and difficult to distinguish from liver malignancies such as intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma due to the lack of characteristic radiological findings.

Intracavitary Drainage Followed by Lobectomy for a Giant Bulla Causing Respiratory Failure due to Severe Mediastinal Compression: A Case Report

Hikaru Tokutake, et al.

INTRODUCTION: We present the case of a giant emphysematous bulla resulting in deteriorating respiratory condition due to severe mediastinal compression that was successfully treated with emergency intracavitary drainage followed by elective right upper lobectomy.

Pulmonary Mycobacterium shigaense Infection with Hemoptysis: Two Surgically Resected Case Reports

Naoko Ose, et al.

INTRODUCTION: Mycobacterium shigaense (M. shigaense) is a rare nontuberculous mycobacterium (NTM) first reported in Japan in 2012. Only a few cases of pulmonary infection have been described, all treated medically. No surgically resected cases or cases presenting with hemoptysis have been reported to date.

Solitary Fibrous Tumor of the Greater Omentum with Intratumoral Infarction: A Case Report

Takumi Funo, et al.

INTRODUCTION: Solitary fibrous tumors (SFTs) are rare mesenchymal tumors with rich vascularity that rarely arise from the greater omentum. Many cases of SFT are asymptomatic and discovered incidentally; however, symptomatic cases may occur when complications such as intratumoral infarction develop. We report a case of an SFT originating from the greater omentum, complicated by intratumoral infarction.

Solitary Gluteal Subcutaneous Metastasis after Curative Resection of Cecal Cancer: A Rare Presentation Preceding Systemic Metastasis

Shusaku Hiyama, et al.

INTRODUCTION: Cutaneous and subcutaneous colon cancer metastases to the gluteal or perineal regions are extremely rare. Unlike the local recurrence or tumor implantation observed in rectal cancer, gluteal or perineal colon cancer metastasis likely represents a distinct pathophysiological mechanism. We report a case of a solitary subcutaneous gluteal metastasis that developed after curative resection of cecal cancer.
