[Advanced Renal Pelvic Tumor Diagnosed after Resection of a Solitary Subcutaneous Metastasis: A Case Report].

A 75-year-old woman had suffered from intermittent gross hematuria. Ultrasonography, enhanced CT, cystoscopy and urinary cytology had no abnormal findings. Four months later, antibiotics were administered for recurrent gross hematuria and urinary frequency, and not effective.

[A Case of Primary Hepatic Lymphoma Diagnosed by Laparoscopic Hepatectomy Affiliation].

An 88-year-old man was referred to our hospital for further examination of an asymptomatic liver tumor. MRI showed low-intensity regions on T1-weighted images, high-intensity regions on T2-weighted images, high-intensity regions on diffusion-weighted images, and low-intensity regions in the arterial, portal, and hepatocyte phases of Gd-EOB-DTPA. PET scan of the tumor was positive, while endoscopy exhibited no malignant findings.

Treatment of a Desmoid Tumor That Enlarged During Pregnancy: A Case Report and Literature Review.

Desmoid tumors are rare soft-tissue tumors that exhibit locoregional aggressiveness and a high local recurrence rate following initial resection. No fixed recommendations have been established with regard to the timing and method of treatment for desmoid tumors that enlarge during pregnancy. Desmoid tumors tend to enlarge during pregnancy, and most do not regress spontaneously postpartum.

A case of focal nodular hyperplasia-like lesion presenting unusual signal intensity on the hepatobiliary phase of gadoxetic acid-enhanced magnetic resonance image.

Focal nodular hyperplasia (FNH) or FNH-like lesions of the liver are benign lesions that can be mostly diagnosed by hepatobiliary phase gadoxetic acid-enhanced magnetic resonance imaging (MRI). Accurate imaging diagnosis is based on the fact that most FNHs or FNH-like lesions show characteristic hyper- or isointensity on hepatobiliary phase images. We report a case of an FNH-like lesion in a 73-year-old woman that mimicked a malignant tumor.

Clinical characteristics and long-term prognosis of type 1 gastric neuroendocrine tumors in a large Japanese national cohort.

Objectives: Optimal management of type 1 gastric neuroendocrine tumors (T1-GNETs) remains unknown, with few reports on their long-term prognosis. This study investigated the clinical characteristics and long-term prognosis of T1-GNETs.

Methods: We reviewed the medical records of patients diagnosed with T1-GNET during 1991-2019 at 40 institutions in Japan.
