These 2 cases highlight the importance of closely monitoring children with ulcerated CH because of the risk of severe bleeding. Embolization is the treatment of choice in the case of severe bleeding, as the natural history of RICH is to spontaneously regress.
Introduction
In adolescents, the occurrence of priapism is commonly related to sickle cell disease and rarely to other causes. We hereby report a case of priapism due to an acquired protein S (PS) deficiency.
Aim
The aim of this study was to describe a young man who developed a priapism with a thrombosis of the corpora cavernosa associated with an anti-PS antibody (anti-PS Ab).
Methods
One week after the onset of an influenza-like illness, a young male developed multiple extensive venous thromboses including a thrombosis of the corpora cavernosa causing painful partial priapism. These thromboses along with purpuric lesions with necrotic vesicles of the feet skin were linked to an acquired PS deficiency due to an anti-PS Ab. The optimal treatment of anti-PS Ab-associated thrombosis is debated but we chose to initiate (i) heparin; (ii) corticosteroids; and (iii) plasmapheresis.
Results
Even if priapism lasted more than 4 days, a full recovery of erectile function was observed within 3 months. As compared with priapism due to sickle cell disease, which is commonly associated with definitive erectile dysfunction, this favorable outcome is noteworthy. The skin healing was complete only 6 months later.
Conclusion
Acquired PS deficiency complicating an infectious disease is a rare, life-threatening condition, associated with substantial morbidity related to amputations of limbs or digits. This is the first report of priapism due to acquired PS deficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
