Overview
Campbell de Morgan spots, also known as Wischnewski spots, are small, benign angiomatous skin lesions typically observed in children but can appear in adults. An outbreak in adults suggests a possible environmental trigger, notably increased ambient temperature, without evidence of infectious etiology 1.Diagnosis
Characterized by small, reddish-brown, telangiectatic papules on the skin.
Histological examination confirms the presence of ectatic capillaries and venules typical of these lesions.
No specific diagnostic tests beyond clinical examination and histopathology are typically required 1.Management
No specific treatment is generally required as these spots are benign and self-limiting.
In cases where cosmetic concerns arise, laser therapy or pulsed dye laser may be considered for lesion reduction 1.Special Populations
Pregnancy: No specific data provided; management likely similar to non-pregnant adults 1.
Pediatrics: Commonly observed in children; spontaneous resolution often occurs without intervention 1.
Elderly: Occurrence noted in adults, suggesting similar benign course; environmental factors like temperature may play a role 1.
Comorbidities: No specific interactions or management adjustments noted for comorbid conditions 1.Key Recommendations
Monitor lesions for changes in appearance or symptoms, as benign nature typically precludes aggressive intervention (Evidence: Expert opinion) 1.
Consider environmental factors, particularly temperature, in the context of outbreaks or increased lesion prevalence (Evidence: Moderate) 1.
For cosmetic reasons, laser therapy may be employed for lesion reduction in adults; however, efficacy and necessity should be individualized (Evidence: Weak) 1.References
