Scedosporium/Lomentospora infections are rare and are associated with a high mortality rate in immunocompromised patients. A 69-year-old man with nontuberculous mycobacteria (NTM) died during induction chemotherapy for acute myeloid leukemia because of multiple organ failure due to pneumonia. ⋯ NTM disease may predispose patients to Scedosporium/Lomentospora infections. Physicians should consider Scedosporium/Lomentospora spp. as an invasive fungal infection that occurs during myelosuppression, particularly when NTM is a complication.

A 75-year-old Japanese woman was admitted to our hospital and diagnosed with hemophagocytic syndrome secondary to severe fever with thrombocytopenia syndrome (SFTS). The patient recovered after steroid treatment and was discharged from the hospital. Two months after the onset of SFTS, the patient revisited our hospital with a fever and palpable purpura on the extremities and trunk. ⋯ Symptomatic treatment resolved the fever, and palpable purpura disappeared 14 days later. No other clinical symptoms or abnormal immunological findings contributed to the leukocytoclastic vasculitis. This is the first report to describe leukocytoclastic vasculitis secondary to SFTS, highlighting a potential association between the two conditions.

Nephrogenic diabetes insipidus (NDI) is characterized by excessive urination and an inability to concentrate urine. Lithium is the most common cause of acquired NDI. Treatment typically involves thiazide diuretics and nonsteroidal anti-inflammatory drugs (NSAIDs). ⋯ We herein report a case of lithium-induced NDI in a 71-year-old woman with lithium-induced NDI. Thiazide diuretics and NSAIDs reduced the urine output by approximately 40% compared to pretreatment, while the addition of desmopressin reduced it by approximately 70%. This case suggests that desmopressin can be a viable treatment option for lithium-induced NDI.

Review Case Reports
New-onset Systemic Lupus Erythematosus Manifestation Following COVID-19: A Case Report and Literature Review.
Coronavirus disease 2019 (COVID-19) is a respiratory viral disease, and several cases of autoimmune diseases have been reported after infection. This report presents the case of a 38-year-old Japanese woman who developed systemic lupus erythematosus (SLE) following COVID-19. Clinical manifestations included dermatological complications, joint pain, and positive autoantibodies. ⋯ Her symptoms improved with immunosuppressive therapy. A literature review identified 10 similar cases, those with lymphopenia and renal involvement. SLE should be considered in patients with persistent nonspecific symptoms after COVID-19 infection, particularly when hematologic and renal involvement are present.
