Meyerson‐Phenomenon hides a nevus flammeus

Abstract

Facial eczema is a common disease in daily dermatological practice. The cause of facial eczema is often atopic dermatitis or allergic contact dermatitis. Usually, the eczema resolves with correct topical treatment and by avoiding allergic trigger factors. A 49-year-old woman presented with persistent eczema on her forehead which recurred over decades despite correct topical therapy. A skin biopsy revealed the astonishing diagnosis of a nevus flammeus with an overlying eczema known as the Meyerson phenomenon. The Meyerson phenomenon is often described in children with nevi flammei suffering from atopic dermatitis - in adults the phenomenon is rarely recognized as a reason for eczema. We show the interesting case of an adult woman with the Meyerson phenomenon on a nevus flammeus and discuss the possible pathomechanisms.

Sudden eruption of multiple Meyerson naevi

“…When MP occurs around a benign pigmented neavus, it is called Meyerson naevus [1][2][3] . MP has been reported encircling different lesions including naevus flammeus [4,5] , acquired melanocytic naevus [1] , congenital melanocytic naevus [6,7] , seborrhoeic keratosis, stucco-keratosis, keloid, benign lentigo, insect bite, basal cell carcinoma, squamous cell carcinoma [8] , dermatofibroma [9] , atypical naevus [10] , and melanoma [10][11][12][13] . The pathogenesis of MP is still not well understood.…”

Eczema within a Capillary Malformation: A Case of Meyerson Phenomenon

“…Meyerson phenomenon, or halo dermatitis, is characterized by the development of a halo or eczematous patch over another skin lesion, such as nevus cell nevus or nevus flammeus1. We report the case of a 10-month-old female infant who showed eczema within a pre-existing capillary malformation.…”

“…Since then, only few cases of eczema over a capillary malformation corresponding to Meyerson phenomenon have been reported134. Most patients usually presented with sharply demarcated, scaly, and eczematous lesions confined within the borders of the capillary malformation1234. Histological examination showed epidermal hyperplasia and spongiosis overlying capillary ectasias1.…”

“…Most patients usually presented with sharply demarcated, scaly, and eczematous lesions confined within the borders of the capillary malformation1234. Histological examination showed epidermal hyperplasia and spongiosis overlying capillary ectasias1. Topical corticosteroid is usually successful for the treatment of eczema, but the lesions tend to recur after treatment discontinuation2.…”

“…Topical corticosteroid is usually successful for the treatment of eczema, but the lesions tend to recur after treatment discontinuation2. Treatment with pulsed dye laser alleviates both capillary malformation and the associated eczema13. However, in some patients, eczematous dermatitis was triggered by the laser treatment itself4.…”
