A high PTX3 level and IgM staining in skin biopsies from HSP patients may be harbingers of subsequent renal involvement.

Prostatic heterotopia is significant in several respects. Either it may be an important cause of hematuria or unusually, as in our case, it may cause rectal bleeding. In addition, ectopic tissue may be endoscopically confused with malignancy in either urinary or lower gastrointestinal system. This and other reports may disclose the genesis and significance of this peculiar tissue remnant.

Numerous genetic pathways associated with glioblastoma development have been identified. In this study, we investigated the prognostic significance of IDH1 and ATRX mutations and WT-1 and p53 expression in glioblastomas and that of surgical methods, radiotherapy and chemotherapy. 83 patients with glioblastomas were retrospectively evaluated. Immunohistochemical analysis was performed for IDH1, ATRX and WT-1 expression. Tumour cells were positive for IDH1 in 9.6% of the patients. In 4.8% of the patients, loss of ATRX expression was observed in tumour cells; 86.7% of the patients were WT-1 positive, and 12.05% of the patients were p53 positive. No statistically significant difference was found in the progression-free and overall survival according to IDH1, ATRX, WT-1 and p53 expression. There was a statistically significant difference in the progression-free and overall survival according to the radiotherapy status. There was a statistically significant difference in the overall survival according to the chemotherapy status. There was no statistically significant difference in the progression-free and overall survival according to the surgical method. IDH1 and ATRX mutations, p53 overexpression and WT-1 expression alone did not have a significant effect on the prognosis of patients with glioblastoma; however, radiotherapy and chemotherapy had a positive effect on survival.
