[A Case of Recurrence-Free Survival for One Year after Surgery, Radiotherapy, and Chemotherapy for Stage Ⅳ Lung Cancer].

The prognosis for stage Ⅳ lung cancer is generally poor. However, there have been reports that local treatment of metastatic disease(that is oligometastatic disease), may improve prognosis. The standard treatment for stage Ⅳ non-small cell lung cancer with distant metastases is chemotherapy, and the efficacy of local therapy for primary tumors and metastases is controversial.

[Sustained Complete Remission after Eradication Therapy in A Helicobacter pylori-Negative Cecum Mucosa-Associated Lymphoid Tissue Lymphoma].

Most primary gastric mucosa-associated lymphoid tissue(MALT)lymphomas are associated with a chronic Helicobacter pylori(H. pylori)infection. The eradication of H.

Invasive candidiasis leading to gastric perforation in an immunocompromised patient.

Invasive candidiasis remains an important cause of mortality and morbidity in patients with underlying diseases. Here, we report a case of gastric perforation due to infection in a 74-year-old-male with Paroxysmal nocturnal hemoglobinuria (PNH) who received long-term corticosteroid treatment of hemophagocytic syndrome associated with acute cholecystitis. Total gastrectomy was performed, and he was treated liposomal amphotericin B.

Ectopic expression of band 3 anion transport protein in colorectal cancer revealed in an autoimmune hemolytic anemia patient.

Cancer patients occasionally have anemia with high mean corpuscular volume in addition to iron deficiency anemia. Secondary autoimmune hemolytic anemia (AIHA) following cancer is also observed with low frequency. To date, no causal mechanisms for these disease states have been reported.

Abdominal aortic aneurysm with periaortic malignant lymphoma differentiated from aneurysmal rupture by clinical presentation and magnetic resonance imaging.

Abdominal aortic aneurysm (AAA) associated with periaortic malignant lymphoma is difficult to differentiate from aneurysmal rupture because of similarities in their clinical presentation and appearance on computed tomography images. We here report a case of AAA associated with periaortic malignant lymphoma diagnosed preoperatively with an absence of typical symptoms, showing that AAA in periaortic malignant lymphoma can present without any clinical correlates. Magnetic resonance imaging was used to confirm the diagnosis.

Pancreatic desmoid-type fibromatosis with beta-catenin gene mutation-Report of a case and review of the literature.

We experienced a rare case of pancreatic desmoid-type fibromatosis (DTF) in a 75-year-old Japanese woman. She was asymptomatic but routine examination including ultrasonography revealed a mass in the abdomen. For precise examination, she was referred to the regional hospital.

Laparoscopy Reveals a Diversity of Peritoneal Change in Patients with Long-Term Vintage of Peritoneal Dialysis.

Background: Although laparoscopy may provide more detailed morphological and histological information about peritoneal damage, its significance in patients with long vintage of peritoneal dialysis (PD) is not elucidated.

Methods: Findings in 12 patients with PD vintage of 7.3 (5.

Central diabetes insipidus in an HHV6 encephalitis patient with a posterior pituitary lesion that developed after tandem cord blood transplantation.

A 60-year-old myelodysplastic syndrome patient underwent tandem cord blood transplantation. The primary cord blood graft was rejected, and human herpesvirus 6 (HHV6) encephalitis developed after engraftment of secondary cord blood. Polyuria and adipsic hypernatremia were observed during treatment of the encephalitis.

[A case of recurrent mantle cell lymphoma with gastrointestinal bleeding].

A 64-year-old man had a sudden onset of gastrointestinal bleeding. He had been diagnosed as systemic mantle cell lymphoma (MCL) 27 months ago, and the first-line chemotherapy was undergone. After maintaining CR state during 12 months, he showed PD.

Use of 5-aminolevulinic acid for the confirmation of deep-seated brain tumors during stereotactic biopsy. Report of 2 cases.

5-Aminolevulinic acid (ALA) has been successfully used to confirm the target tumor tissues obtained during stereotactic biopsy. The authors report their experience with 2 patients who underwent stereotactic biopsies of thalamic malignant lymphoma and pontine glioma utilizing 5-ALA. Intraoperatively, the tumor specimens fluoresced, allowing for confirmation that the obtained target specimen contained tumor tissues.

Large cell neuroendocrine carcinoma of the mediastinum with alpha-fetoprotein production.

Large cell neuroendocrine carcinoma (LCNEC) is a relatively new category of pulmonary neuroendocrine tumor. Although it was first detected in the lung, LCNEC has since been found in a variety of extrapulmonary sites. We now describe a patient who was diagnosed with LCNEC originating from the mediastinum, an extremely rare disorder.

Idiopathic granulomatous appendicitis treated surgically with long-term follow-up: report of a case.

Isolated granulomatous inflammation of the appendix is extremely rare, and its etiology is still unknown. Thus, differentiating between idiopathic granulomatous appendicitis and isolated appendiceal Crohn's disease is difficult. We report a case of idiopathic granulomatous appendicitis with long-term follow-up after surgery.

Pulmonary lymphoma of mucosa-associated lymphoid tissue type followed as a long-standing indeterminate lesion in immunoglobulin M-type paraproteinemia.

An 82-year-old woman with monoclonal immunoglobulin (Ig) M-type paraproteinemia had a large opacity in the right lung field. The abnormal shadow on roentgenogram had persisted for more than 6 years since the initial diagnosis of paraproteinemia, which had been diagnosed as Waldenström's macroglobulinemia (WM). Computed tomography revealed the lesion as a pulmonary tumor which was finally diagnosed as a marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) after surgical removal.

Pulmonary nodules 10 mm or less in diameter with ground-glass opacity component detected by high-resolution computed tomography have a high possibility of malignancy.

Objectives: For the histological diagnosis of small lung cancers of 10 mm or less in diameter (< or =10), resection by video-assisted thoracic surgery (VATS) with computed tomography (CT)-guided marking is feasible. One problem is that a small number of these pulmonary nodules are malignant. We retrospectively analyzed CT images of pulmonary nodules to find better criteria to select candidates for resection among patients with small pulmonary nodules.

Growth of herpes simplex virus in epidermal keratinocytes determines cutaneous pathogenicity in mice.

Herpes simplex viruses (HSV)-1 and -2 isolated from genital lesions were examined for cutaneous pathogenicity and its correlation with cellular tropism. HSV-1 caused vesiculation, erosion/ulcer, and zosteriform lesions successively, but skin lesions of HSV-2 developed without vesiculation in some mice, and with statistically significantly less frequent vesiculation than HSV-1. Thus, the virological type of HSV was correlated with its cutaneous pathogenicity.

A patient with membranoproliferative glomerulonephritis diagnosed by the third biopsy via endocapillary proliferative glomerulonephritis and focal membranoproliferative glomerulonephritis.

We present a girl with type I membranoproliferative glomerulonephritis (MPGN) diagnosed by the third renal biopsy. The first renal biopsy was performed at age 11.2 years after microscopic hematuria (which was revealed by school urinary screening) had persisted for 3 months, along with a low level of serum C3.

Laparoscopic resection of intra-abdominal esophageal duplication cyst.

Esophageal duplication cysts are frequently encountered in the mediastinum and rarely in the abdomen. A case of laparoscopic resection of an intra-abdominal esophageal duplication cyst is reported. An incidental 4.

Solitary necrotic nodule of the liver.

Solitary necrotic nodule of the liver is a rare benign lesion; only 22 cases have been reported to date. An unsolved problem in treating these lesions involves the difficulties in differential diagnosis; specific features of necrotic nodule of the liver in preoperative examinations have not been identified. Here, we report a patient with resected solitary necrotic nodule of the liver with preoperative features shown on ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) examinations.
