BACKGROUND: Rectal leiomyosarcoma (LMS) is an extremely rare disease. Previously, LMS was not properly distinguishable from gastrointestinal stromal tumor (GIST) until c-kit, a characteristic marker of GIST, was discovered in 1998. No standard therapeutic strategy for gastrointestinal LMS has been established except for surgical resection because of its rarity. Rectal LMS is often accompanied by symptoms, which can enable detection at a small size. However, when a large LMS is detected at the lower rectum, it is difficult to excise due to the narrow pelvic space...

BACKGROUND: Undifferentiated carcinoma (UC) of the liver is extremely rare, and its clinicopathological characteristics have not been fully elucidated. CASE PRESENTATION: The present study reports the case of a 56-year-old male with UC of the liver. At 16 days post-admission, the patient suddenly succumbed due to intra-abdominal bleeding resulting from a ruptured liver. Macroscopic examination revealed that the hepatic parenchyma was almost completely replaced by innumerable minute nodules...

Median sternotomy is frequently selected for the resection of pulmonary artery tumor, and pneumonectomy is performed for complete resection. However, it is difficult to see the inferior pulmonary vein and transect it safely via median sternotomy, so additional thoracotomy is often required and this is highly invasive. In the present case, we employed thoracoscopy (which we routinely use for VATS lobectomy) to transect the inferior pulmonary vein via median sternotomy without additional intercostal thoracotomy...

Solitary fibrous tumors (SFTs) are relatively rare neoplasms that commonly occur in the pleura. The pathological feature of SFTs is a proliferation of spindle-shaped cells in interlacing or storiform fascicles. SFTs appear to derived from pluripotential submesothelial cells, but not the covering mesothelium. SFTs distinctively show diffuse staining for CD34 but lack staining for smooth muscle markers. We herein report a relatively rare case of a 68-year-old male patient without symptoms, who underwent resection for what was considered to be SFT...

Undifferentiated carcinoma of the ampulla of Vater is a rare disease with unclear and clinical characteristics and prognosis. Here, we report the case of a 61-year-old man with undifferentiated carcinoma of the ampulla of Vater. He presented to our hospital with an increase in hepatobiliary system enzymes that was detected during a health check-up. Imaging and endoscopy demonstrated a tumor with ulcer in the ampulla of Vater, which was diagnosed as a carcinoma by biopsy. No distant metastasis was observed. Subtotal stomach-preserving pancreaticoduodenectomy was performed...

BACKGROUND: Planning the surgical strategy for a gastrointestinal stromal tumor (GIST) at the posterior wall of the lower rectum is difficult, as the procedures for the lower rectum are hampered by poor visualization and may cause anal dysfunction or discomfort. We report a novel procedure to resect a submucosal tumor of the rectum. CASE PRESENTATION: A 75-year-old woman presented with metrorrhagia. Endovaginal ultrasonography showed a low echoic tumor. Computed tomography showed an enhanced tumor, measuring 5...

An asymptomatic 26-year-old man received an annual medical check-up, and chest X-ray showed a protrusion of the aortopulmonary window. Chest computed tomography (CT) revealed an anterior mediastinal tumor and cysts with thin wall and septum enhancement. The preoperative diagnosis was cystic thymoma or malignant lymphoma. We performed total resection of the tumor through a median sternotomy. The pathological findings revealed seminoma, positive for c-kit stain, and multilocular thymic cysts. Cysts were lined by normal squamous epithelium and no seminoma cells were located on their surface...

BACKGROUND: Mucin-producing cholangiocarcinoma (MPCC) is an uncommon tumour that is clinically characterized by mucin-hypersecretion. Because the initial symptoms of MPCC may be attributed to the viscus mucobilia, the primary tumour mass may potentially be unrecognizable. We report an interesting case of curatively resected occult MPCC in situ. CASE PRESENTATION: A 70-year-old man was referred to our hospital with increased levels of biliary enzymes. Multidetector row computed tomography (MDCT) demonstrated a diffuse dilatation of the entire biliary system without evidence of tumour mass...

BACKGROUND: A cavenous hemangioma of the appendix (CHA) is rare. The clinical pathophysiology and adequate management of a CHA have not been sufficiently explained since reports on CHA are scarce. CASE PRESENTATION: A 56-year-old woman presented with chronic right lower quadrant pain. Abdominal contrast-enhanced computed tomography revealed a thickened appendix (1.5 cm in diameter) and some focal calcifications in the appendiceal wall. No acute inflammatory signs were visible around the appendix...

BACKGROUND: Acute esophageal necrosis (AEN) is a rare clinical disorder. Esophageal stenosis or obstruction is one of severe complications, but there are a few reports about surgical treatments. In such a situation, it still remains controversial which to choose, esophagectomy or bypass operation. CASE PRESENTATION: A 61-year-old woman was admitted to the local hospital for septic shock with diabetic ketoacidosis due to necrotizing fasciitis of the right thigh. Three days later, she had hematemesis, and gastrointestinal endoscopy revealed black mucosal coloration throughout the entire esophagus...

BACKGROUND: Dermatomyositis (DM) is a rare syndrome that belongs to the group of idiopathic inflammatory myopathies. The association between DM and malignancy is well recognized, and the severity of DM symptoms has been linked to the progression of metastatic disease. CASE PRESENTATION: We report the case of a 42-year-old man that was diagnosed with dermatomyositis (DM) and rectal cancer. Proctectomy was performed, and DM symptoms were resolved postoperatively. One year and 9 months after the surgery, liver metastasis occurred accompanied by the exacerbation of DM symptom...

BACKGROUND: Intra-abdominal lymphangiomas are rare, benign tumors in adults. This report is the third documented case of a lymphangioma originating in the hepatoduodenal ligament that mimicked a simple liver cyst. CASE PRESENTATION: A 50-year-old woman was admitted with a cystic tumor in the right lobe of her liver and underwent laparoscopic excision of the cyst. Operative findings revealed that the cyst had developed in the hepatoduodenal ligament, not in the liver...

BACKGROUND: A mediastinal air cyst is a rare computed tomography (CT) finding. Once the lesion is identified, it is difficult to diagnose and treat. Meanwhile, bronchial diverticula have been reported as a CT finding observed in certain pulmonary pathologic conditions. We encountered the case of an enlarged mediastinal air cyst accompanied with bronchial diverticula and upper lobe-dominant fibrous changes of the lung. CASE PRESENTATION: A 69-year-old man with a chronic cough who had regularly visited a chest physician for upper lobe-dominant pulmonary fibrosis was referred to our hospital for the examination of an enlarged mediastinal air cyst...

BACKGROUND: The spontaneous rupture of nonparasitic liver cysts (NLC) is sometimes seen in clinical practice. However, there are no guidelines that describe the optimal treatment strategy and the surgical indications for an NLC rupture due to a small number of reports. Here, we present a case who underwent elective laparoscopic deroofing to treat a spontaneously ruptured NLC that had undergone conservative treatment. CASE PRESENTATION: A 67-year-old woman was referred to our hospital for the evaluation of acute abdominal pain after the conservative treatment of an NLC at another hospital...

BACKGROUND: Chronic mesenteric ischemia (CMI) is a rare disease; however, symptomatic CMI has a risk of acute exacerbation without timely revascularization. CASE PRESENTATION: A 54-year-old man who had had postprandial pain for 6 months was admitted to our hospital because of vomiting and diarrhea. Although the celiac and superior mesenteric arteries were occluded at the proximal portion, contrast enhancement of the bowel wall was good in contrast-enhanced computed tomography (CECT)...

BACKGROUND: Hypertrophic pyloric stenosis (HPS) is a rare cause of gastric outlet obstruction beyond infancy. Ramstedt pyloromyotomy remains the gold standard treatment for HPS. This type of HPS can be managed successfully with pyloromyotomy under laparoscopic or open procedures. Endoscopic pyloric balloon dilation (EPBD) has not been recommended in the treatment of HPS, and there are only a small number of reported cases who had had successful endoscopic pyloromyotomy (EP) for HPS only in infants...

A 53-year-old male visited his primary physician for epigastric and back pain. Abdominal-enhanced computed tomography (CT) revealed a simple cyst of the pancreatic tail attached to the stomach. A distal main pancreatic duct (MPD) was clearly dilated, but no pancreatic tumor was identified around the stenosis of MPD by CT scan and magnetic resonance cholangiopancreatography (MRCP). Endoscopic retrograde pancreatography (ERP) revealed stenosis and distal dilation of the MPD located between the body and tail of the pancreas...

Cardiac rupture is defined as a full-thickness myocardial tear; this injury after blunt chest trauma is rare, and is associated with high mortality. Blunt cardiac rupture typically presents with either cardiac tamponade or massive hemothorax, and is often unrecognized in the context of blunt chest trauma. It is a little known fact that pericardial effusions can decrease due to pericardial lacerations. Hence, cardiac rupture with pericardial lacerations may be easily overlooked especially by chest surgeons. We herein report a case of hemothorax caused by rupture of the left atrial appendage...
