Polyarteritis nodosa (PAN) presents mostly as a systemic disease characterized by necrotizing vasculitis affecting small- and medium-sized arteries. Rarely, the inflammatory process is isolated and involves a single organ without systemic manifestations. We described the case of a 57-year-old patient with isolated testicular PAN who presented with a testicular mass mimicking a primary testicular tumor.

Polyangiitis overlap syndrome (POS) is a systemic vasculitis characterized by overlapping features of more than one well-defined vasculitic syndrome. We present the case of a 38-year-old Malay man with progressive dyspnea and palpable purpura in his lower limbs. The diagnostic evaluation revealed right-sided segmental pulmonary consolidation with pleural effusion, systolic cardiac dysfunction with the presence of an intracardiac thrombus, and left vocal cord palsy secondary to laryngeal mononeuropathy.

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.
