Abstract
We present a 29-month-old male patient in follow-up due to pyelocaliceal dilation with a prostatic nodule incidentally found during ultrasound evaluation. Cysto video endoscopy was performed and a prostate biopsy, obtained. Microscopic evaluation showed a haphazardly distributed population of muscular cells with cross striations without evidence of mitosis or necrosis. Immunohistochemistry was positive for myogenin and desmin and negative for smooth muscle actin. Next generation sequencing was performed without finding any pathogenic variant or fusion in the tumor RNA. The patient received no further treatment, remained asymptomatic and continues in follow up, 3 years after initial diagnosis. We report a case of prostate rhabdomyoma in a toddler, an exceptional location that raises concern about differential diagnosis with its malignant counterpart, rhabdomyosarcoma, especially at this age.

Abstract
Obesity is accompanied by chronic inflammation of VAT, which promotes metabolic changes, and purinergic signaling has a key role in a wide range of inflammatory diseases. Therefore, we addressed whether fat inflammation could be differentially modulated by this signaling pathway in the MUO and in individuals who remain MHO. Our results show that the necrotized VAT of both groups released greater levels of ATP compared with lean donors. Interestingly, MUO tissue SVCs showed up-regulation and engagement of the purinergic P2X7R. The extracellular ATP concentration is regulated by an enzymatic process, in which CD39 converts ATP and ADP into AMP, and CD73 converts AMP into adenosine. In VAT, the CD73 ectoenzyme was widely distributed in immune and nonimmune cells, whereas CD39 expression was restricted to immune CD45PAN+ SVCs. Although the MUO group expressed the highest levels of both ectoenzymes, no difference in ATP hydrolysis capacity was found between the groups. As expected, MUO exhibited the highest NLRP3 inflammasome expression and IL-1β production. MUO SVCs also displayed up-regulation of the A2AR, allowing extracellular adenosine to increase IL-1β local secretion. Additionally, we demonstrate that metabolic parameters and BMI are positively correlated with purinergic components in VAT. These findings indicate that purinergic signaling is a novel mechanism involved in the chronic inflammation of VAT underlying the metabolic changes in obesity. Finally, our study reveals a proinflammatory role for adenosine in sustaining IL-1β production in this tissue.
