Abstract PDF PubReader ePub: Herpes zoster virus infection is common and results in significant morbidity in patients who have undergone solid organ transplantation. Herpes zoster can involve the cranial nerves, and vagus nerve involvement is an infrequent primary manifestation of herpes zoster. Here, we describe a rare presentation of disseminated herpes zoster infection with vagus nerve involvement in a kidney transplant recipient. A 62-year-old man who had undergone kidney transplantation 3 years prior presented to our clinic with sore throat and hoarseness, followed by multiple vesicular-pustular rashes on the face and trunk. Flexible laryngoscopy revealed left paramedian vocal cord paralysis with multiple ulcerative lesions extending from the left pyriform sinus to the epiglottis. Computed tomography of the neck, abdomen, and chest revealed no significant abnormalities that could have caused vocal cord paralysis. We confirmed the diagnosis of disseminated herpes zoster after herpes zoster laryngitis based on positive blood tests and polymerase chain reaction for varicella zoster virus antibodies. The skin rashes and laryngeal ulcers rapidly resolved after treatment with intravenous acyclovir and high-dose steroids. The patient still had persistent dysphagia and microaspiration as assessed by a video fluoroscopic swallowing study, but showed improvement in dysphagia in response to swallowing rehabilitation therapy. This case provides valuable insights into the presenting symptoms of disseminated herpes zoster, which can cause acute vagus neuritis in solid organ transplantation recipients.

Parathyroid carcinoma (PC) in cases of secondary or tertiary hyperparathyroidism is relatively uncommon, and only a few case reports have described this entity. Although some papers have reported patients with one or two parathyroid malignancies, multiple PC–especially three or more–have been even more rarely reported. Herein, we report a case of secondary hyperparathyroidism due to multiple PCs in a chronic hemodialysis patient. A 54-year-old man with end-stage kidney disease was referred for hyperparathyroidism. He had been diagnosed with chronic kidney disease in 2001 and had begun hemodialysis in 2009. In laboratory tests, intact parathyroid hormone (iPTH) was markedly elevated to 1,144.1 pg/mL (normal range: 15.0–68.3 pg/mL) and serum calcium was mildly elevated to 10.56 mg/dL (normal range: 8.5–10.3 mg/dL). Ultrasonography showed hypoechoic nodules in the posterior part of both thyroid glands. All three nodules showed increased uptake on a 99mTc sestamibi scan. The patient underwent total parathyroidectomy with autotransplantation to the right forearm. Histopathology findings showed three PCs with capsular invasion and one parathyroid hyperplasia. In the immediate postoperative period, the iPTH level dropped from 1,446.8 to 82.4 pg/dL and, after 1 month, to 4.0 pg/dL. This patient needed oral calcium carbonate and active vitamin D to maintain appropriate serum calcium levels. Although multiple PCs are rare, they can cause secondary hyperparathyroidism. Therefore, clinicians should suspect multiple PCs when patients’ serum iPTH levels are exceptionally high. Additionally, since PCs could occur in multiple glands, autotransplantation of the parathyroid gland after parathyroidectomy should be done carefully.
