Summary
Cutaneous polyarteritis nodosa (CPAN) is a rare vasculitis affecting skin arteries. This case highlights a benign presentation in a teen, successfully treated with steroids.
Area of Science:
- Dermatology
- Rheumatology
- Pathology
Background:
- Cutaneous polyarteritis nodosa (CPAN) is a rare vasculitis affecting dermal and subcutaneous arteries.
- It presents with specific skin manifestations like nodules, gangrene, and ulcerations, without systemic disease.
Observation:
- A 14-year-old girl presented with fever, subcutaneous nodules, cutaneous ulcer, and digital gangrene.
- The clinical presentation was consistent with CPAN.
Findings:
- Skin biopsy revealed leukocytoclastic vasculitis and fibrinoid necrosis in dermal vessels.
- These findings confirmed the diagnosis of cutaneous polyarteritis nodosa.
Implications:
- This case demonstrates a rare benign presentation of CPAN in an adolescent.
- Complete resolution was achieved with corticosteroid therapy, highlighting effective treatment options.

01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
01:22Pericarditis I: Introduction
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...
01:26Peripheral Artery Disease IV: Nursing Management
The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...
