RESUMEN
Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disease associated with psoriasis. Its major clinical domains include peripheral and axial arthritis, enthesitis, dactylitis and skin and nail involvement. Approximately 30% of patients with psoriasis develop psoriatic arthritis. The pathophysiology of PsA is complex and involves a dysregulated immune response. In particular, interleukin (IL)-23 is a major regulatory cytokine that has been implicated in PsA, including bone remodeling, enthesitis, synovitis and psoriatic lesions. Risankizumab is a humanized immunoglobulin G1 monoclonal antibody that targets the p19 subunit of IL-23. It has been approved for the treatment of moderate-to-severe plaque psoriasis and, more recently, PsA. The efficacy and safety of risankizumab for the treatment of PsA has been demonstrated in phase 2 and phase 3 clinical trials. Risankizumab showed efficacy in decreasing the number of swollen and tender joints, clearing psoriatic plaque and improving quality of life. Treatment with risankizumab was well-tolerated, with the most common adverse event being upper respiratory tract infection. Overall, the current literature demonstrates that risankizumab is both a safe and effective therapeutic option for the treatment of PsA. Herein, week 24 and 52 results are reviewed.

A postmenopausal female patient presented with vaginal bleeding. Initial bloodwork revealed an elevated serum beta human chorionic gonadotropin level (ß-hCG). Pelvic MRI identified a complex heterogeneous uterine mass with central necrosis. She underwent total abdominal hysterectomy with bilateral saplingo-oopherectomy. Pathology reported a malignant perivascular epithelioid cell tumour (PEComa). Postoperatively, her ß-hCG level returned to normal. ß-hCG secreting sarcomas are extremely rare, and to our knowledge, there has only been one previously reported case of a ß-hCG secreting PEComa. Based on the limited literature, these tumours may have a worse prognosis. The role of ß-hCG as a marker of treatment response and disease activity is unclear. Additional studies are required to further ascertain its role as a predictive and prognostic biomarker.
