Adenoid cystic carcinoma (ACC) is a rare type of malignant tracheal tumor originating from the secretory glands. Complete surgical resection is the current standard of care for tracheal ACC. ⋯ CCRT was completed with a good response and safety, and the patient is currently receiving durvalumab as maintenance therapy. Durvalumab after CCRT can be a treatment option for patients with unresectable tracheal ACC.

Focal Segmental Sclerosis Associated with the Novel Multi-tyrosine Kinase Inhibitor Ponatinib: A Case Report.
Ponatinib is a novel multi-tyrosine kinase inhibitor (TKI) with potent inhibitory activity against refractory chronic myeloid leukemia (CML). Despite its high clinical efficacy, ponatinib induces various adverse events due to its multi-target characteristic. ⋯ Our patient developed proteinuria and renal function deterioration during treatment with ponatinib but not with imatinib or nilotinib. We herein report the first case of a patient with secondary focal segmental glomerulosclerosis (FSGS) with partial glomerular collapse induced by ponatinib treatment.

Case Reports
Advanced Appendiceal Cancer with Systematic Metastasis without Gastrointestinal Symptoms Found by Subcutaneous Tumor.
An 86-year-old woman with a subcutaneous nodule in her left axilla visited our hospital. She had no gastrointestinal symptoms, but contrast-enhanced computed tomography revealed a cecal mass and systemic metastasis, including cutaneous, bone, peritoneal dissemination and ascites. Colonoscopy revealed a circumferential, elevated cecal lesion. ⋯ The pathological diagnosis was poorly differentiated adenocarcinoma (por1>tub2>muc) arising from the appendix with a BRAFV600E mutation and microsatellite instability-high. Chemotherapy was administered, and she is currently still alive and undergoing chemotherapy. We describe a rare case of advanced appendiceal cancer without gastrointestinal symptoms diagnosed due to cutaneous metastasis.

We herein report two cases of rapidly progressive fatty liver (FL) disease due to pancreatic exocrine insufficiency (PEI) without a surgical history. Two women, 59 and 72 years old, with no history of abdominal surgery presented to our hospital with severe anorexia and nausea persisting for one week. Examinations revealed progressive, marked FL disease with hepatomegaly and PEI, for which pancreatic enzyme replacement therapy was effective. Commonly known causes of PEI include chronic pancreatitis, abdominal surgery (e.g. pancreaticoduodenectomy), pancreatic cancer, and obstruction of the pancreatic duct, none of which were present in either of these two cases.

We herein report a case of idiopathic refractory ascites following allogeneic hematopoietic cell transplantation that was successfully treated with ibrutinib. A 39-year-old man presented with massive transudative ascites. ⋯ The ascites dramatically improved, and the portal venous pressure was reduced. This case may help clarify the mechanism through which refractory ascites develops after allogeneic hematopoietic cell transplantation and establish appropriate treatment protocols.
