Sudden eruption of multiple Meyerson naevi

Abstract

Abstract:We present a case of a young patient presenting with a six-month history of multiple squamous pink and light brown papules surrounded by symmetrical eczema on the trunk. Dermoscopy revealed light brown structureless and avascular lesions with an erythematous scaly halo. The patient denied the presence of naevi on the sites of the newly emerging changes. Histopathology revealed acanthotic epidermis and linear clusters of morphologically normal naevi cells in the upper dermis, infiltration of lymphocytes, plasma cells, eosinophils and mild spongiosis in the dermis. Topical betamethasone/gentamicin ointment twice daily for 10 days was prescribed. The erythematous scaly area around lesions completely disappeared on the follow-up visit after six months. This is a unique case of a sudden appearance of newly formed multiple benign dermal naevi with Meyerson phenomenon-the sudden eruption of multiple Meyerson naevi.

Meyerson phenomenon in lobular capillary hemangioma

“…It has been described with conditions like seborrheic keratosis, molluscum contagiosum, dermatofibroma, stucco keratosis, lentigo, keloid, insect bite, as well as basal cell and squamous cell carcinomas. [ 1 2 ] There are few reports of MP with vascular conditions like capillary malformation and angiokeratoma; however, there are no reports with lobular capillary hemangioma. [ 3 4 ] Lobular capillary hemangioma (pyogenic granuloma) is a reactive, sessile/pedunculated tumor-like lesion of varying color from red, purplish, to pink, depending on the vascularity of the lesion.…”

“…Usually, it is asymptomatic although sometimes it may manifest pruritus. [ 2 ] It is generally more common in atopics. Sunburn, chemotherapy, or treatment with interferon alpha has been implicated as triggering factor.…”
