Infiltrating giant cell tumor in a case of Paget’s disease of bone

Giant cell tumor (GCT) of the bone, also called osteoclastoma, is a rare complication of Paget’s bone disease. We report a patient from Southern Italy who developed a GCT infiltrating the neighboring tissues. The natural history and the therapeutic outcomes of this unique complication of Paget’s bone disease are presented

Giant cell tumor in a case of Paget's disease of bone: an aggressive benign tumor exhibiting a quick response to an innovative therapeutic agent

Giant cell tumor of bone, also called osteoclastoma, is a rare skeletal complication of Paget’s disease of bone. We here report a patient from Southern Italy who developed a GCT infiltrating the neighboring tissues. We will focus on either a review on this rare bone tumor, including some genetic aspects, or the current established therapies. Since this case has been published in International literature, here we report the updated clinical findings on it. Finally, we will describe the therapeutic outcomes of this unique complication of Paget’s disease of bone as a rapid response to an innovative therapeutic agen

Idiopathic chronic urticaria and thyroid autoimmunity: Experience of a single center

Urticaria is one of the most frequent dermatosis, being its prevalence in general population estimated about 20%. This prospective case-control study was aimed at determining the prevalence of thyroid autoimmune disorders in a cohort of patients with chronic urticaria (CU), all living within an area with mild-to-moderate iodine deficiency. Fifty four consecutive patients affected by CU were recruited and compared to 108 healthy controls. Assessment of the thyroid function included measurement of serum concentrations of TSH, FT3, FT4, anti-thyreoglobulin (anti-TG) and anti-peroxidase (anti-TPO) antibodies. Ultrasound scan of the thyroid gland was performed in all subjects using a 7.5 MHz linear transducer. All subjects were followed up for 6 months. The prevalence of thyroid antibodies was significantly higher in our cohort of patients with CU than in controls (22% vs. 6.5 %). Hashimoto's thyroiditis was also more frequent in patients than controls (18.5% vs. 1.8%). These frequencies do not differ from those previously reported by some other authors and confirm the association between CU and thyroid autoimmunity also in the area of iodine deficiency. However, presence of antibodies or thyroiditis does not seem to influence clinical course of CU. These results suggest that screening for thyroid function may be useful in all the patients with CU

Limitations of Chromogranin A in clinical practice

Usefulness of circulating Chromogranin A (CgA) for the diagnosis of neuroendocrine tumors (NEN) is controversial. The aim of the present study was to assess the actual role of this marker as diagnostic tool
