ObjectiveTo analyze the clinical features,diagnosis and treatment of male idiopathic hypogonadotropic hypogonadism (IHH).MethodsClinical data of 92 male IHH cases were analyzed retrospectively.ResultsThe mean age at evaluation was 21.0 ± 3.2 yrs,and 52 patients were diagnosed with Kallman syndrome (KS; IHH with anosmia/hyposmia) while the remainder were normosmic IHH (nIHH).All had normal radiological imaging of the hypothalamic and pituitary areas.The level of serum LH,FSH and T was low,and the clinical parameters (development of secondary sexual characteristics,sexual function,and serum testosterone levels.) were significantly improved after hormone replacement therapy.ConclusionsDiagnosis and differential diagnosis of IHH can be clearly defined based on clinical features and laboratory results.Hormone replacement therapy is an effective treatment option.

Solitary fibrous tumor (SFT) in bladder is extremely rare. In this study, we reported one case of bladder SFT and reviewed the only ten cases of the disease that had been reported so far. The patient suffered from residual urine sensation and urethral pain. Cystoscopy revealed a 7-cm protruding mass at the dome of the bladder, and bladder mucosa biopsy showed normal differentiation of the bladder mucosa with a small amount of inflammatory cells. Radical resection of the tumor was performed in this patient. Pathological examination found uniform, haphazardly arranged spindle cells, the majority of which were CD34-positive and Vimentin-positive and proved that the mass was a solitary fibrous tumor. Within a period of 9 months of follow-up, no reoccurrence was found.
