Background:Neurofibromatosis type 1 is an autosomal dominant disorder characterized by an increased incidence of tumors, including endocrine ones. Primary hyperparathyroidism can be rarely caused by a parathyroid carcinoma; these patients are generally characterized by severe symptoms, large neck lesions and high levels of PTH and calcium. We report a case of hyperparathyroidism due to parathyroid carcinoma in a patient affected by neurofibromatosis type 1. A systematic review of the literature was also conducted.Patient Findings:A 56-year-old woman was referred for a 13 mm-nodular lesion of the neck incidentally discovered on ultrasound examination and mild hyperparathyroidism. A 99mTctetrofosmin/ pertechnetate subtraction scintigraphy was negative for parathyroid disease. Given the absence of suspicious ultrasound finding, a fine-needle aspiration cytology was performed with iPTH determination in the aspirate, confirming the parathyroid origin of the lesion. The patient underwent left inferior parathyroidectomy with intraoperative monitoring of iPTH and became normocalcemic. On histopathological examination, parathyroid carcinoma presenting at the resection margin was diagnosed, thus a surgery revision was requested.Conclusion:Even if literature does not support a syndromic association between neurofibromatosis type 1 and primary hyperparathyroidism, the benefit of precociously diagnosing and treating this condition may outweigh costs associated with screening. This case report moreover demonstrates that sometimes clinical, laboratory and imaging aspects suspicious for cancer may be missing. A prompt referral to a high-volume center is crucial for the management of those cases of incidental histopathological diagnosis.

Introduction. Neurofibromatosis type 1 (NF1), also known as von Recklinghausen disease, is one of the most common single-gene disorders (mutation on chromosome 17q) and usually associated with cutaneous, musculoskeletal and neurological disorders in humans. NF1 is generally complicated with one or more neurobehavioral disorders or tumors located in the peripheral nervous system such as neurofibromas, peripheral nerve sheath tumor, pheochromocytoma, etc. In the available medical literature, the thoracic manifestations of NF1 have been rarely described in these patients. There are few reports about intrathoracic neurogenic tumors, kyphoscoliosis, pneumonitis and pulmonary fibrosis in patients with NF1. Case report. A 65-year-old female was admitted to the Intensive Care Unit at the Lung Clinic of Belgrade University Clinical Center of Serbia. The patient?s general condition was poor with shortness of breath and present cyanosis. At the same time, the skin changes similar to NF1 were noticed, which were additionally documented by her medical history and diagnosed as NF1. After the application of noninvasive mechanical ventilation and other emergency respiratory medicine measures, the patient soon felt better. The parenchymal changes were viewed by subsequent X-rays and CT scanning of the thorax. Conclusion. This is a case report presenting the NF1 associated with the abnormality of lung parenchyma established during diagnostic procedures at the Intensive Care Unit, Clinic of Pulmonology.
