Case Reports
Enlargement of Intrathoracic Goiter with Unilateral Phrenic Nerve Paralysis Leading to Cardiopulmonary Arrest.
As an intrathoracic goiter expands, it causes airway stenosis and phrenic nerve paralysis, and slight respiratory stimuli can trigger sudden life-threatening hypoventilation. A 78-year-old obese woman with a large intrathoracic goiter was found unconscious with agonal breathing in her room early in the morning. ⋯ She underwent surgical removal of the goiter; however, she required long-term mechanical ventilation because of atelectasis due to phrenic nerve paralysis. In patients with large intrathoracic goiters, difficulty breathing on exertion and diaphragm elevation on chest X-ray may be significant findings predicting future respiratory failure.

Case Reports
Unusual Overlapping Cardiac Sarcoidosis and Long-QT Type 3 Induced Ventricular Fibrillation.
A 54-year-old woman had been resuscitated after ventricular fibrillation and her electrocardiogram showed a QT prolongation (QTc=510 ms), and genetic screening revealed a missense variant, R1644C, in the SCN5A gene. She was therefore diagnosed with congenital long-QT syndrome (LQTS) type 3. ⋯ Although both are rare diseases, their overlapping presence in this case may have led to an increased cardiovascular risk compared with either alone. Thus, not only genetic but comprehensive clinical examinations are important for making a correct diagnosis.

The case was a 76-year-old man with chronic limb-threatening ischemia. Plain old balloon angioplasty (POBA) was performed on the popliteal artery. Subsequently, he suffered from cellulitis around the POBA site, followed by reocclusion. ⋯ We performed aneurysmectomy and bypass grafting with the saphenous vein and then continued antibiotic therapy. Although treatment consisted of endovascular therapy (EVT) with nothing left behind, management was difficult because of secondary infectious complications. We conclude that prophylactic antibiotics before EVT should be considered in such cases.

A 61-year-old man who underwent surgery for rectal adenocarcinoma developed multiple hepatic nodules. The nodules were 1-3 cm without a capsular structure or contrast enhancement on computed tomography/magnetic resonance imaging, findings that were atypical for adenocarcinoma metastases. A biopsy showed the aggregation of eosinophils without larval bodies, ova, or granulomas. ⋯ He had been taking the commercial herbal medicine Ganoderma lucidum for his liver function. After discontinuing G. lucidum, the eosinophil counts and liver enzyme levels rapidly resolved, and the nodules disappeared completely. This is a rare case of hypereosinophilia with hepatic nodules reactive to herbal medicine rather than a parasitic infection.

We herein report an unusual case of granulomatosis with polyangiitis (GPA) in a 65-year-old man in whom relapsed disease manifested as an anterior cheek nodule. Magnetic resonance imaging indicated the differential diagnoses of the subcutaneous nodule in the patient's anterior cheek to be inflammatory granulomatous lesions with GPA, malignancy, or infectious disease. ⋯ The subcutaneous nodule was successfully treated using rituximab, suggesting that it was associated with GPA, secondary to vasculitis. Clinicians should be aware of the possibility of such a rare manifestation of GPA.
