Schamberg disease is the most frequent purpuric of the dermatoses, with a classical presentation characterized by petechiae, purpura, and increased skin pigmentation. It is a benign and chronic condition, although idiopathic in origin, the diagnosis is not a dilemma since it is mainly made by inspections and identification of classic morphology of the lesions. The biopsy is required to rule out mycosis fungoides. This activity highlights the role of the interprofessional team in the evaluation and treatment of Schamberg disease.
Outline the typical morphology of the lesions in Schamberg disease. Identify the available treatment options for Schamberg disease.Vasculitides, characterized by inflammation and damage of blood vessels, encompass a broad spectrum of diseases. They can occur with different pathophysiological mechanisms and have a rich clinical heterogeneity depending on the vessel diameters they affect. Vasculitides may also present with a broad spectrum of severity, ranging from a mild self-limiting to a potentially life-threatening disease. The high prevalence of skin involvement in vasculitis, visible character and, finally, the easy accessibility of the skin for both physical examination and biopsy offers important advantages for prompt disease recognition and diagnosis. Thus, dermatologists are privileged to diagnose the disease earlier and more effectively than any other discipline. As a consequence, a detailed clinical and histopathological evaluation of the skin is one of the most critical steps in diagnosing vasculitis. Besides obtaining a good medical history, laboratory and radiological evaluation methods are used in the diagnosis. In this review, a practical and algorithmic approach is aimed to assist in the diagnosis of vasculitis. However, this approach should not be seen as strict rules. This stepwise algorithmic diagnostic approach for vasculitis was developed by combining the current literature knowledge and the author's experience in this field to provide a rational framework for selecting the most appropriate among various diagnostic approaches.
Vasculitis refers to a broad and heterogeneous disease spectrum characterized by inflammation and damage of the blood vessel. It may occur in any organ of the body. When skin vessels are affected, the term cutaneous vasculitis is used. In systemic vasculitis, blood vessels of at least one organ are affected in addition to the skin. Of note, besides being a component of systemic vasculitis, including the skin, cutaneous vasculitis can be a skin-limited or skin-dominant expression or variant of systemic vasculitis. Finally, it may be a single-organ vasculitis of the skin (1). The skin is one of the most frequently affected organs in vasculitis, and small-vessel vasculitis of the skin is the most common vasculitis dermatologists encounter in their clinical practice (2). While the disease affects both genders equally, its frequency increases with age at diagnosis. Cutaneous vasculitis may present at any age, but it is more common in adults than children. The clinical course of the disease is usually self-limiting in children, and IgA vasculitis is the most common vasculitis in this age group. Idiopathic etiology is more prominent in adults and infectious etiology in children. Compared with children, underlying systemic vasculitis, connective tissue disease, or malignancy are more common in adult patients (3, 4).
Schamberg disease represents the most common type of pigmented purpuric dermatoses (PPDs), a chronic, benign, cutaneous eruptions characterized by petechiae, purpura, and increased skin pigmentation (brown, red, or yellow patchy). The PPDs are grouped into five clinical entities: Schamberg's purpura, Majocchi purpura, lichen aureus, Gougerot-Blum purpura and, eczematoid-like purpura of Doucas and Kapetanakis.[1]
The exact cause of Schamberg disease is not known. It is caused by extravasation of blood vessels particularly capillaries which allow red blood cells to get deposited into the skin which then releases their iron from hemoglobin. This iron causes a rust color accounting for the orange or brown tint of the rash.[4]
The exact cause of capillary inflammation is unknown and can be multifactorial. Potential contributors in the etiology can be:
Drugs such as acetaminophen, aspirin, adalin, amlodipine, carbromal, chlordiazepoxide, glipizide, glybuzole, hydralazine, meprobamate, nitroglycerin, persantin, reserpine, thiamine, interferon-alfa, injection medroxyprogesterone acetate, topical fluorouracil, and sildenafil[7][8][9][10][11]
Genetic causes, as cases are seen in family members[12]
