Association between the paracaval branches of the caudate lobe and the three major hepatic veins in liver casts: Locating the cranial boundary of the caudate lobe.

According to Couinaud's definition, the cranial boundary of the caudate lobe is delineated by the three major hepatic veins. However, many branches of the caudate lobe go through the ceiling that is composed of these hepatic veins. The cranial boundary of the caudate lobe should be determined by employing the portal segmentation.

Right hemihepatectomy preserving the fluorescently visible paracaval portion of the caudate lobe.

The paracaval portion (PC) of the caudate lobe is a small area of the liver located in front of the inferior vena cava. Conventional right hemihepatectomy (RH) along the Rex-Cantlie line involves resection of not only the anterior and posterior sections but also the PC behind the middle hepatic vein (MHV). However, to preserve the future liver remnant volume as much as possible, PC-preserving RH may be beneficial in selected patients.

Primary syphilis presenting as a painful unilateral inguinal lymphadenopathy, without cutaneous manifestations, in a 71-year-old Japanese man: A case report.

Syphilitic infection is usually observed in young patients, and the first stage of the disease (primary syphilis) is characterized by painless cutaneous and lymph node lesions. Herein, we describe a 71-year-old Japanese man with primary syphilis that presented as unilateral inguinal lymphadenopathy without skin lesions. Originally, an incarcerated hernia was clinically suspected.

Demonstration of the right-side boundary of the caudate lobe in a liver cast.

There have been historical arguments about the boundary of the caudate lobe of the liver. Kumon M first advocated the definition of the caudate lobe based on the portal segmentation of the liver in 1985, and classified it into three parts, Spiegel lobe, paracaval portion and caudate process. Prof.

Definition of the caudate lobe of the liver based on portal segmentation.

Models of liver corrosion were developed by injecting colored Mercox, epoxy resin, silicon rubber and other materials into the portal vein, hepatic artery, bile duct and hepatic vein of autopsied livers. The glissonean or venous branches that obstructed the view of the caudate lobe of the liver were subsequently removed. The detailed anatomy of the caudate vessels was studied and the three parts of the caudate lobe (Spiegel lobe, paracaval portion and caudate process) were defined based on portal segmentation.

Incidence and risk factors of osteoporotic status in outpatients who underwent gastrectomy for gastric cancer.

Background And Aim: Disorders in bone metabolism have long been recognized as typical sequelae of gastrectomy; however, the pathogenesis has not been fully elucidated, resulting in a variation of reported incidence. This study aimed to evaluate current bone health by measuring bone mineral density (BMD) in patients treated by gastrectomy for gastric cancer, with a focus on incidence and risk factors of osteoporosis.

Methods: The study enrolled 81 patients who underwent gastrectomy for gastric cancer at Kochi Medical School.

Metachronous solitary splenic metastasis arising from early gastric cancer: a case report and literature review.

Background: The metastasis of malignant tumors to the spleen is rare, and only a small percentage of cases can be treated surgically, as splenic metastases generally occur in the context of multivisceral metastatic cancer at a terminal stage. We report a rare case of metachronous solitary splenic metastasis arising from early gastric cancer.

Case Presentation: A 75-year-old man was initially referred to our hospital for examination of gastric cancer, diagnosed at a medical check-up.

Rapid growing fibroadenoma in an adolescent.

Introduction: We report a case of rapidly growing fibroadenoma.

Patient: A 13-year-old girl consulted the outpatient clinic regarding a left breast mass. The mass was diagnosed as fibroadenoma by clinical examinations, and the patient was carefully monitored.

Inflammatory pseudotumor of the liver: report of a case diagnosed by needle biopsy.

We report a case of a 76-year-old man with inflammatory pseudotumor, xanthogranuloma type of the liver. The patient showed clinical manifestations of a liver abscess. Abdominal sonography and computed tomography revealed an additional tumor-like lesion adjoining the liver abscess.

Stromal sarcoma of the breast with lung metastasis successfully treated by radiotherapy: report of a case.

We report herein the case of a 42-year-old woman in whom a solitary lung metastasis from stromal sarcoma of the breast was effectively treated by radiotherapy. The original breast tumor had been extirpated in a local hospital, and she was subsequently referred to our outpatient clinic for nonsurgical treatment. Pathological examination of the breast tumor had confirmed a diagnosis of stromal sarcoma.
