Cryoballoon ablation has been established as an effective method for pulmonary vein isolation and has recently been investigated for its efficacy of substrate modification on the left atrial roof area in patients with persistent atrial fibrillation. We herein report the first successful case of left atrial posterior wall isolation including roof line ablation using cryoballoons in a patient with persistent atrial fibrillation, dextrocardia, and situs inversus. Cryoballoon ablation proved to be a safe and straightforward approach to create lasting lesions along the left atrial roof line and left atrial posterior wall, even under challenging anatomical conditions.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal-dominant vascular disorder characterized by intractable epistaxis, mucocutaneous telangiectasias, and arteriovenous malformations (AVMs) in multiple organs, including the lungs, liver, gastrointestinal tract, brain, and spinal cord. We herein report a 50-year-old Japanese man with HHT who experienced recurrent epistaxis, telangiectasia in the cornea, apex of the tongue and fingers; hepatic AVM; and a poorly developed main arterial trunk in the right middle cerebral artery. A genetic analysis revealed a novel heterozygous mutation in the activin A receptor-like type 1 gene, with a frameshift mutation in NM_000020.3:c.826_836del (p. Ile276ProfsTer112).

Case Reports
Two Cases of Gastric Adenocarcinoma with Enteroblastic Differentiation which Demonstrated Rapid Progressive Courses.
We herein report two extremely rare cases of gastric adenocarcinoma with enteroblastic differentiation (GAED) that underscore the aggressive nature of GAED. Case 1: endoscopic submucosal dissection (ESD) was scheduled for early-stage gastric cancer, however, the tumor increased in size drastically and the morphology changed to type "0-I + IIc" in one month. Surgery was performed and the patient was diagnosed with GAED. ⋯ The horizontal margin was positive for clear cells in the muscularis mucosa. Additional surgery was performed; however, recurrence occurred one year later. Therefore, the treatment strategies should be carefully considered for GAED.

Objective The efficacy of anamorelin in pancreatic cancer (PC) patients with a poor performance status (PS) is uncertain, as previous trials have excluded such patients. This study evaluated the efficacy of anamorelin in PC patients with a poor PS (2) compared with those with a good PS (0-1). Methods We retrospectively reviewed consecutive PC patients with cachexia who received anamorelin at our institution. ⋯ A poor PS was associated with early discontinuation of anamorelin. Conclusion The efficacy of anamorelin is extremely limited in PC patients with a poor PS. Patients with PC with a poor PS may not be good candidates for anamorelin compared to those with a good PS.

Although sarcoid-like reactions are uncommon in colorectal cancer, they can coexist with other cancers. We herein report a 50-year-old woman with sigmoid adenocarcinoma and osseous sarcoid-like reactions that resembled metastases. ⋯ Bone and lymph node biopsies revealed epithelioid non-caseating granulomas with bone trabeculae, resulting in a final diagnosis of pathological T2N2aM0, Stage IIIB. When the expected depth of invasion differs from that of typical bone metastases, colorectal cancer-associated bone lesions should be evaluated for sarcoid-like reactions.
