Case Report: Atypical Presentation of Idiopathic Retroperitoneal Fibrosis

Roshniben Patel, MD, Simon Go, MD, Akhila Mohan, MD, & Maria Pardi, MD  |  

Retroperitoneal fibrosis (RPF) is a rare condition characterized by aberrant fibroinflammatory tissue developing in the retroperitoneum. This disorder was initially called Ormond’s disease. RPF may be idiopathic or secondary to other conditions. Idiopathic RPF is a part of the disease spectrum of chronic periaortitis due to its typical periaortoiliac localization. Idiopathic retroperitoneal fibrosis is a…

Case Report: Persistent Knee Warmth Mimics Juvenile Idiopathic Arthritis

Eman Bamashmous, MBBS, Buthaina Al Adba, MBBS, CABP, & Sharon Bout-Tabaku, MD, MSCE  |

Presenting symptoms of this rare subtype of venous malformation often include nonspecific pain and joint swelling, which may be episodic, and accompanied by limited range of motion. The signs and symptoms can mimic juvenile idiopathic arthritis (JIA). Timely diagnosis of…

Medium-sized blood vessels are seen in the dermis and at the dermal-subcutaneous junction. The black arrow identifies a venule, and the blue arrow points to a fibrin deposition in the vessel wall. Extravasated neutrophils and erythrocytes are seen in the interstitium.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that typically affects medium-sized muscular arteries. The clinical subsets of PAN are idiopathic, generalized, secondary hepatitis B virus (HBV) associated and cutaneous PAN. These clinical subsets are important because of their therapeutic implications. Virtually any organ system can be affected in generalized PAN, but this vasculitis tends…
