ABSTRACT
Primary biliary cholangitis (PBC) is a chronic progressive cholestatic liver disease of uncertain etiology. Although PBC is frequently complicated by Sjögren's syndrome and chronic thyroiditis, it can also be associated with a variety of other autoimmune disorders. We herein describe a rare case of immune thrombocytopenic purpura (ITP) coexistence with PBC and localized cutaneous systemic sclerosis (LcSSc). A 47-year-old woman with PBC and LcSSc who was positive for antiphospholipid antibody experienced a rapid decrease in platelet count to 1.8 × 104/µL during follow-up. After clinical findings ruled out thrombocytopenia from cirrhosis, a diagnosis of ITP was made following bone marrow examination. Her human leukocyte antigen (HLA) type was HLA-DPB1*05:01, which has been associated with disease susceptibility to PBC and LcSSc, but not to ITP. A careful review of similar reports suggested that in PBC, other collagen disease complications, positive antinuclear antibody, and positive antiphospholipid antibody may all support a diagnosis of ITP. Clinicians should be vigilant for ITP when rapid thrombocytopenia is observed during the course of PBC.

A 57-year-old man visited our hospital for evaluation of an abnormal shadow identified on chest radiography. Chest computed tomography findings suggested diffuse bone metastases in the thoracic spine and the bilateral ribs. Notably, 18- fluoro-deoxyglucose positron emission tomography revealed no evidence of the primary tumor. Esophagogastroduodenoscopy revealed a small flat depressed lesion in the greater curvature of the gastric angle. Histopathological examination of this specimen revealed a signet-ring cell carcinoma. Histopathological examination of a biopsy obtained from the right iliac bone revealed a signet-ring cell carcinoma similar to that observed in the gastric mucosa. He was diagnosed with a gastric signetring cell carcinoma with multiple bone and bone marrow metastases. Cervical metastases caused gradual worsening of respiratory functions, necessitating artificial ventilation. He died of sudden ventricular tachycardia on the 36th day. Clinicians should be aware of the features of primary gastric cancer with bone and bone marrow metastases for early diagnosis and prompt treatment.

A 48-year-old man presented with a sustained fever. Abdominal computed tomography revealed multilocular liver abscesses. He underwent percutaneous needle aspiration, yielding straw-colored pus. Gram staining revealed Gram-negative coccobacilli. The organism grew only on chocolate II agar in a 7% carbon dioxide atmosphere. Identification of Aggregatibacter aphrophilus was confirmed using mass spectrometry and 16S rRNA gene sequencing. He was successfully treated with antibiotics. Liver abscess caused by A. aphrophilus is extremely rare. We herein report the first such case in Japan. Even fastidious organisms, such as A. aphrophilus, should be correctly identified using mass spectrometry or 16S rRNA gene sequencing for adequate treatment.

We present an unusual case of a 35-year-old male patient whom a patency capsule stayed in his gut without breaking. He has a history of Peutz-Jeghers syndrome and multiple abdominal surgeries. Prestudy was performed for abdominal searching, but a patency capsule remained in the colon over 9 days. He displayed neither abdominal nor obstructive symptoms in that period. We collected the patency capsule using colonoscopy after dilating a postoperative stricture at an anastomotic site of the rectum. Clinicians should bear in mind that patency capsules may become retained as distally as the colon in patients with a surgical history of the large intestine.
