Two Cases with Isolated Splenic Sarcoidosis Diagnosed by an Ultrasound-guided Fine-needle Aspiration Biopsy.

Asymptomatic splenic nodules were detected incidentally in two middle-aged women at an annual checkup. They showed no abnormalities on laboratory tests, but imaging studies revealed splenic nodules. No other localized lesions were found.

Impact of Interferon-Free Direct-Acting Antivirals on the Incidence of Extrahepatic Malignancies in Patients with Chronic Hepatitis C.

Background: The incidence of extrahepatic malignancies (EHMs) after hepatitis C virus (HCV) eradication by interferon (IFN)-based and IFN-free direct-acting antivirals (DAAs) treatment remains unclear.

Aims: The aim was to evaluate the cumulative incidence of EHMs diagnosed for the first time after the antiviral treatments.

Methods: We analyzed a total 527 patients with chronic HCV infection and without prior history of any malignancies who achieved sustained virological response by antiviral treatments, including IFN-based (n = 242) or IFN-free DAAs (n = 285).

Rapid Progression of Liver Fibrosis Induced by Acute Liver Injury Due to Immune-related Adverse Events of Atezolizumab.

A 72-year-old woman with advanced lung cancer had received systemic chemotherapy including atezolizumab. About three months after the initial administration of atezolizumab, her liver enzyme levels increased. The histopathological findings of the initial liver biopsy revealed acute inflammatory infiltrate, predominantly CD3, CD4 and CD8 T lymphocytes, in the hepatic lobules.

Type 4B hereditary hemochromatosis due to heterozygous p.D157A mutation in SLC40A1 complicated with hypopituitarism.

Hemochromatosis is a clinical syndrome characterized by iron overload in various organs. We present here a case of type 4 hereditary hemochromatosis due to heterozygous mutation in SLC40A1 gene (p.D157A).

Hepatic Inflammatory Pseudotumor Protruding from the Liver Surface and Directly Penetrating the Colon.

A 69-year-old man was diagnosed with a liver abscess and received antibiotics at a local hospital. He was referred to our hospital due to a persistent fever. He had hepatic masses protruding from the liver surface toward the transverse colon.

Importance of a Liver Biopsy in the Management of Wilson Disease.

A 37-year-old Wilson disease patient treated with D-penicillamine visited our hospital for the evaluation of his liver function. Laboratory data showed a low serum copper level and ceruloplasmin. The ratio of urinary copper to urinary creatinine in a spot urinary analysis after 4 days' cessation of D-penicillamine was under 0.

Recombinant Thrombomodulin Used to Successfully Treat Cronkhite-Canada Syndrome with Disseminated Intravascular Coagulation due to Sepsis in a Compromised Patient.

Cronkhite-Canada syndrome (CCS) is a rare non-inherited disease characterized by gastrointestinal polyposis, chronic diarrhea, ectodermal dysplasia, skin hyperpigmentation, hair loss and nail atrophy. Although the efficacy of corticosteroid and immunomodulatory agents has been demonstrated, no standard therapy regimen has been established, and the prognosis of CCS is still poor due to various complications. We here in report a CCS patient complicated with severe sepsis and disseminated intravascular coagulation who was successfully treated by combined modality therapies, including recombinant human soluble thrombomodulin.
