Case Reports
Paraneoplastic Cerebellar Degeneration Leading to an Early Diagnosis of Peritoneal Serous Papillary Carcinoma.
A 77-year-old female with a subacute progression of ataxia and serum anti-Yo antibodies was suspected to have paraneoplastic cerebellar degeneration (PCD). An examination of an underlying cancer showed no abnormality in the gynecological organs, but the findings did show a mass in the Douglas fossa. ⋯ PCD was treated with intravenous immunoglobulin (IVIG). For an early diagnosis and treatment, PSPC should be included in the list of malignancies that cause PCD with anti-Yo antibodies.

Review Case Reports
An Extremely Delayed Onset of Frey Syndrome: A Case Report and Literature Review.
We report the case of an 80-year-old man with Frey syndrome that developed 30 years postoperatively, which is an exceptionally long period before its occurrence. Sweating and flushing occurred on only the side of his face where the surgery was performed, and he had no other causative abnormalities. ⋯ Various surgical methods to prevent this syndrome have been explored, but complete prevention has not yet been achieved. These findings suggest that the underlying pathophysiology of Frey syndrome may be more complex than previously recognized.

Case Reports
Autopsy of Drug-induced Lung Injury with Atypical Diffuse Alveolar Disorder due to Amiodarone: A Case Report.
Amiodarone, a prominent antiarrhythmic drug, may cause lung injury. We herein report the case of an 87-year-old man who had been taking amiodarone for 5 years and was subsequently referred due to respiratory failure. Chest computed tomography revealed multiple consolidations with air bronchograms in both lungs. ⋯ Autopsy revealed hyaline membrane formation and organic formation with fibrin deposition. Drug-induced lung injury caused by amiodarone was confirmed by autopsy. Caution is therefore required when fibrin deposition in the alveolar spaces is observed in such cases, which are prone to suffer a rapid deterioration.

An 83-year-old man diagnosed with multiple myeloma presented with renal failure and hyperkalemia. The patient was treated with calcium polystyrene sulfonate (CPS: kalimate) for hyperkalemia. ⋯ There was a protrusion within the trachea surrounding the CPS crystals, inflammatory cells, and granulation tissue. This case suggests that CPS is associated with not only gastrointestinal complications, but also with airway complications.
