Metastatic tumors to the breast reportedly account for 0.5% to 2.0% of all malignant breast diseases. Such metastatic tumors must be differentiated from primary breast cancer. Additionally, few reports have de...
Neuroendocrine carcinomas (NECs) of the colon are among the rarest types of colorectal cancers. Among these, large cell type neuroendocrine carcinoma (LCNEC) is particularly rare. Colorectal NEC is an aggressi...
Nodular fasciitis (NF) is a type of rare and rapidly growing tumor that affects the muscular fascial layers. Due to its locally aggressive nature and rapid growth, NF can be mistaken as a malignant process on ...
Non-occlusive mesenteric ischaemia (NOMI) is a condition in which intestinal ischaemia arises due to spasms of peripheral blood vessels; however, there is no obstruction of the main arteries. Risk factors incl...
Peritoneal dissemination associated with the postoperative recurrence of breast cancer is relatively low (3–6%). Although the prognosis of patients with peritoneal metastasis is generally short (7–26 months), ...
Ehlers–Danlos syndrome (EDS) type IV is a rare subtype of EDS, but has important surgical implications.
Spontaneous regression (SR) of a malignant tumor is the partial or complete disappearance of primary or metastatic tumor tissue in the absence of treatment, which can be temporary or permanent. Here, we report...
There have been few reports on surgically treated primary lung cancer accompanied by contralateral partial anomalous pulmonary venous connection (PAPVC). In such cases, repair of the PAPVC might be necessary t...
The efficacy of resection of pancreatic cancer metastases has not been established. We here report two patients with long-term survival after resection of lung and liver metastases.
Malignant phyllodes tumors (PTs) of the breast occur infrequently and are difficult to treat with adjuvant therapy. Here, we present a case of a female patient with a huge malignant PT with rapid progression i...

Mesenteric cysts have various histological forms, including mesenteric cystadenomas and borderline cystic neoplasms. Primary cystadenocarcinoma of the mesentery is extremely rare; therefore, the clinical and r...
Glomus tumors (GTs) are mesenchymal neoplastic lesions arising from the glomus bodies and generally occur in the fingers and toes. Gastrointestinal GTs are rare, and most of them originate from the stomach; ho...
Postoperative biliary strictures are commonly related to accidental bile duct injuries or occur at the site of biliary anastomosis. The first-line treatment for benign biliary strictures is endoscopic therapy,...
Metastatic cancer to the stomach is relatively rare. Prostate-specific antigen (PSA) is a reliable biomarker used in the screening and management of patients with prostate cancer. However, it is difficult to d...
Pancreatic cancer is a disease with a poor prognosis, requiring multidisciplinary treatment combining chemotherapy and surgery for effective management. Distal pancreatectomy with celiac axis resection (DP-CAR...
The mainstay treatment for arteriovenous malformation in the pancreatic head (Ph-AVM) is standard pancreatectomy, especially pancreaticoduodenectomy (PD), or interventional endovascular treatment. We report th...
Adult intussusception is recognized as an abdominal emergency. More than 90% of adult patients with intussusception have distinct causes that are related to benign or malignant tumors. In contrast, idiopathic ...
Solitary fibrous tumor (SFT), a mesenchymal fibroblastic tumor with a hypervascular nature, rarely develops in the pelvis. Resection of a giant SFT occupying the pelvic cavity poses an increased risk of develo...
Chemotherapy has been considered the main treatment for stage IV gastric cancer (GC). However, advances in chemotherapy have provided new clinical approaches, permitting conversion surgery with the aim of R0 r...
Although the primary treatment for malignant phyllodes tumor (PT) is complete surgical excision with either breast-conserving surgery or total mastectomy, recent technical advances have led to the adoption of ...
The stomach has many incoming vessels and is resistant to ischemia due to the rich microvascular network within its submucosal layer. Although reports of gastric remnant necrosis after gastrectomy have been ra...
Meningeal carcinomatosis is a very rare metastatic site of gastric cancer and meningeal carcinomatosis without other metastatic sites is much extremely rare. Herein, we report our experience with a very rare c...
