Polyarteritis Nodosa Case Study

Decent Essays

Discussion:
Polyarteritis Nodosa is an autoimmune disease caused by immune deposition in the wall of small to medium sized muscular arteries.13 This process promotes infiltration with polymorphic leukocytes and liberation of necrotizing enzymes, leading to thrombosis, tissue ischemia, fibrosis, and ultimately tissue scarring. PAN may affect virtually every organ system and has a wide constellation of clinical manifestations (Table 1).14 Establishing the diagnosis of PAN is very difficult as there are no laboratory abnormalities specific for PAN. Acute phase reactants, such as erythrocyte sedimentation rate and C-reactive protein, are commonly increased.14 Chronic anemia is also frequently present.14 Histopathological evidence of vascular inflammation …show more content…

Each time he presents with testicular pain was treated for medical conditions ranging from groin strain and epididymo-orchitis to testicular torsion, but this time he was presented with testicular pain along with weight loss and fever. In the present case, a thorough history and clinical examination along with biochemical analyses enabled us to exclude all the common causes of acute unilateral testicular pain (Table 2). Testicular pain and systemic symptom development are worth to think something beyond the local disease. As the recurrent attacks of testicular pain was the chief complaint in patient, which raises our concern to suspect PAN as an interpretation of the systemic features of the patient and history of hepatitis B virus infection. Our suspicious further strengthen when CRP and ESR were elevated, which later on confirmed by histopathological finding of right testicular biopsy. It surprises us, when PAN diagnosis comes up on the basis of histopathological report on testicular biopsy in a disease limited to the testes without affecting any other organ as the diagnosis of isolated testicular PAN is a rare phenomenon and is usually not considered a differential on patients presenting with unilateral testicular
