Article Synopsis
- VEXAS syndrome is a genetic disorder that causes bone marrow failure and systemic inflammation, which can lead to a higher risk of infections for affected patients.
- In a study of 94 patients with VEXAS, 6% developed pneumonia (PJP), 15% experienced reactivation of the alphaherpesvirus, and 10% had non-tuberculous mycobacterial infections.
- The research found that developing PJP or NTM significantly increases the risk of death, while prophylactic treatments for these infections were shown to be highly effective in reducing infection rates.
. The sinonasal tract is the second most common site of human papillomavirus (HPV)-related carcinomas in the head and neck. Published data on the association between sinonasal tumors and HPV are quite inconsistent among different regions.

The patient also had complaints of new-onset testicular swelling at the time of imaging. Although the metastatic bone disease showed a complete metabolic response to treatment, 18F-FDG PET/CT demonstrated significantly increased metabolic activity in bilateral testicular mass.

Herein we report a case of a 64-year-old man patient with suspected hematologic malignancy who underwent 18F-FDG and 68Ga-pentixafor PET/CT. Both scans demonstrated diffusely increased activity related to bone marrow involvement.

The present study assessed the cut-off values of the pre-bx PSA level, maximum tumor diameter, radial and circumferential distances of EPE, and circumferential length of surgical margin (SM) positivity with regard to BCR.
Material And Methods: The study included 445 radical prostatectomy specimens, and the cut-off values of all parameters were determined using receiver operating characteristic curve analysis.
