Polyarteritis nodosa (PAN) may be systemic or isolated in distribution and may involve virtually any organ or tissue in the body. We report an unusual case of PAN with the clinical features of both penile and renal involvement in a 21-year-old man diagnosed incidentally by pathologic examination of the nephrectomized left kidney. Systemic and surgical therapeutic procedures were applied and his symptoms resolved within 6 weeks. Penile ulceration is a rare but serious manifestation of PAN that needs prompt and aggressive treatment.

Objective: Autoimmune diseases are systemic conditions that can have negative effects on wound healing. The objective of the present study was to investigate the efficacy of combining bone marrow-derived mesenchymal stem cells (BM-MSCs), acellular dermal matrix (ADM), split-thickness skin graft (STSG), and negative-pressure wound therapy (NPWT) for treating patients with autoimmune diseases and chronic non-healing wounds.
Methods: Thirty-four patients with autoimmune diseases and non-healing chronic wounds of the lower extremities between 2012 and 2023 were included in the study.

Background: Polyarteritis nodosa is a relatively uncommon type of systemic necrotizing vasculitis that primarily affects medium-sized arteries. While gastrointestinal involvement is known in polyarteritis nodosa, heavy gastrointestinal bleeding due to gastric ulceration is relatively uncommon. We present the case of an 81-year-old male of Chinese ethnicity who experienced severe gastrointestinal bleeding as a result of polyarteritis nodosa and an innovative treatment approach for a better patient outcomes.

Polyarteritis nodosa (PAN) is a rare systemic necrotizing vasculitis that can lead to the formation of refractory lower limb ulcers requiring amputation. The standard treatment for severe PAN involves combination therapy with steroids and cyclophosphamide; however, some cases prove to be challenging. Recently, case reports have described the use of biological agents for PAN treatment.

Article Synopsis
- The study investigates the effectiveness of a new imaging technique, fluorine-18-labeled FAP inhibitor (FAPI-42), for detecting systemic vasculitis in patients, comparing it to the standard FDG imaging technique.
- A retrospective analysis of 30 patients revealed that FAPI-42 had a higher detection rate for lesions (100% vs. 93.3%) and identified more lesions overall compared to FDG (161 vs. 145).
- FAPI-42 also showed a moderate correlation with inflammatory markers, suggesting it may be a valuable tool for assessing systemic vasculitis severity.
