Case Reports
Deterioration of Vocal Cord Paralysis after COVID-19 Infection in Multiple System Atrophy.
Multiple system atrophy (MSA) is a progressive neurodegenerative disease that often causes vocal cord paralysis (VCP), Parkinsonism, cerebellar ataxia, and autonomic dysfunction. VCP is the most fatal symptom that affects the prognosis of patients with MSA. ⋯ We herein present two cases of patients with MSA in whom VCP worsened after COVID-19 and this led to the need to perform emergency tracheostomies. As VCP may deteriorate after COVID-19 in patients with MSA, it is important to prevent COVID-19 in these patients and closely monitor such patients for any signs of VCP deterioration post-infection to improve their prognosis.

Case Reports
A Case of Hereditary Coproporphyria in which the Patient's Course Improved after the Discontinuation of Givosiran.
Hereditary coproporphyria (HCP) is caused by a partial deficiency of coproporphyrinogen oxidase during heme biosynthesis. Givosiran is approved for the treatment of acute hepatic porphyria. ⋯ However, givosiran was discontinued after six months due to a decreased renal function. The patient's ALA and PBG levels remained within the normal ranges, and her HCP-related symptoms resolved more than 2 years after the discontinuation of givosiran.

Rosai-Dorfman disease (RDD) is a rare histiocytic proliferative disorder characterized by lymphadenopathy and extra-nodal manifestations. Some patients with RDD require systemic treatment, but there is no consensus on the treatment strategy owing to its extreme rarity. ⋯ We herein report the first case of RDD with cutaneous involvement and arthritis that was successfully treated with methotrexate and infliximab. This case highlights the potential efficacy of anti-TNF-α therapy for RDD, offering a novel treatment option for this rare condition.

A 59-year-old man was admitted to our hospital with hyponatremia. An endocrine examination indicated panhypopituitarism, and magnetic resonance imaging revealed a mass-like lesion in the pituitary gland. Sinus endoscopy revealed a fungal mass in the sphenoid sinus, and the patient was diagnosed with hypopituitarism due to aspergillosis of the central nervous system (CNS). ⋯ Although the right internal carotid artery was eventually occluded, antifungal medications were administered for the aspergillosis, and the patient's general condition improved. The patient's CNS lesions have remained under control since discharge. This is the first case to suggest that ACTH secretion may be relatively preserved in Aspergillus-induced hypopituitarism.
