A 46-year-old woman with exacerbating hemoptysis and dyspnea was diagnosed with diffuse alveolar hemorrhage (DAH). High doses of glucocorticoids were initiated, but afterward, paroxysmal hypertension (210/140 mmHg) with headache and abdominal pain appeared. A 50-mm left adrenal tumor with an intense uptake by iodine-123 metaiodobenzylguanidine scintigraphy and catecholamine hypersecretion revealed complication with pheochromocytoma. Because high doses of glucocorticoids, sometimes required for DAH, can provoke life-threatening paroxysmal hypertension in pheochromocytoma and paraganglioma (PPGL), our case suggests that PPGL needs to be recognized as the cause of DAH and should be detected with whole-body imaging before starting glucocorticoids.

Multicenter Study
Immediate or Interval Endoscopic Papillary Large-balloon Dilation after Limited Endoscopic Sphincterotomy for Bile Duct Stone Removal.
Objective Endoscopic papillary large-balloon dilation (EPLBD) with limited endoscopic sphincterotomy (EST) is widely used for removing multiple large common bile duct (CBD) stones. However, the safety and effectiveness of immediate EPLBD after limited EST and EPLBD at an interval after limited EST is unclear. Thus, this multicenter retrospective study was conducted to examine this matter. ⋯ The immediate EPLBD group had significantly fewer mean ERCP sessions for complete stone removal and a significantly lower rate of endoscopic mechanical lithotripsy (EML) usage than the interval EPLBD group [1.6 vs. 2.4 sessions, p<0.001; and 4/33 (12.1%) vs. 12/33 (36.4%), p=0.042, respectively]. Conclusion The incidence of post-ERCP complications in the immediate EPLBD group was not significantly different from that in the interval EPLBD group. Compared with interval EPLBD, immediate EPLBD may result in a reduced number of ERCP sessions for complete stone clearance and reduce the rate of EML usage.

A 70-year-old woman was hospitalized with dyspnea. A transthoracic echocardiogram indicated an elevated systolic pulmonary artery pressure, and the cytology specimens obtained using a pulmonary artery catheter confirmed adenocarcinoma metastasis. ⋯ Tumor cells in the bladder were immunohistochemically positive for GATA3, indicating micropapillary urothelial carcinoma, which is a rare variant of urothelial carcinoma and considered an adenocarcinoma subtype. This case is the first autopsy case of pulmonary tumor thrombotic microangiopathy (PTTM) associated with micropapillary urothelial carcinoma of the urinary bladder.
