ACTA ENDOCRINOLOGICA (BUC)

Paget’s disease is a disorder of aging bone which occurs in the setting of accelarated bone remodelling. In the presented case we discuss the difficulties in the diagnosis of Paget’s disease in a 77 year old patient with coexisting endometrium carcinoma. The patient was initially diagnosed with metastatic bone disease due to endometrium adenocarcinoma when she was admitted to oncology clinic with pelvic pain. Bone scintigraphy with Tc99 and (18) F fluorodeoxyglucose positron emission tomography/CT revealed an increased uptake on the bone lesions which were reported as metastatic bone involvement. Although the (18) F-FDG uptake was much higher than the levels that would generally be anticipated in a case with Paget’s disease, high levels of bone turnover markers indicated further evaluation in the differential diagnosis and the definitive diagnosis of Paget’s disease was established with the pathological evaluation of bone biopsy.

abdominal cystic lesions should include investigation of cystic pheochromocytomas. To date only a few cases of purely cystic pheochromocytoma have been reported in the English literature. Aim. To present the management in four cases of silent pheochromocytomas patients who presented with pure or partially cystic abdominal lesions with benign (n:3) and malignant characteristics (nonspecific neuroendocrine tumor) (n:1) in histological evaluation. Results. Resection of the tumor is considered the primary treatment option in the management of pheochromocytoma, and preoperative preparation with alpha and beta antagonists is crucial in order to avoid precipitation of hypertensive crisis during surgical procedures. The absence of clinical symptoms and lack of typical radiological features may complicate the diagnosis of pheochromocytoma resulting with increased mortality and morbidity during surgery. Conclusion. Asymptomatic pheochromocytomas are rare and they are responsible for approximately 5% of adrenal incidentalomas. These lesions may be referred to surgery as clinically nonfunctional adrenal adenomas.
