Case Reports
Successful Use of Certolizumab Pegol for Refractory Psoriatic Arthritis Triggered by COVID-19 Infection.
Recently, the coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, has spread worldwide. Although nearly all patients incur mild-to-moderate disease from this viral infection, some develop severe manifestations with a poor prognosis. ⋯ We herein report a case of psoriatic arthritis triggered by COVID-19. Although the arthritis had been refractory to glucocorticoids and methotrexate, certolizumab pegol subsequently led to remission.

A 49-year-old man developed severe hyponatremia associated with transient headache and was diagnosed with syndrome of inappropriate antidiuretic hormone secretion (SIADH). Fluid restriction and sodium supplementation corrected the hyponatremia. ⋯ A case of RCC exhibiting headache, hyponatremia, and subsequent hypernatremia has been reported. Our case shows that CDI may appear after SIADH in patients with RCC, especially in those with serum sodium levels that unexpectedly increase rapidly beyond the reference range.

We herein report a rare case of fast-growing benign metastasizing leiomyoma. A 52-year-old woman was admitted to our hospital with abnormal chest shadows. Chest computed tomography showed well-circumscribed cystic tumors. ⋯ One possible reason for the fast growth of the tumor was enlargement of the cysts. Malignant diseases characterized by cystic tumors are rare but occasionally reported. Therefore, differentiation by a pathological examination is essential.
