We report 2 cases of benign intradermal melanocytic nevi with discrete glandular elements and mucin deposition engendering a diagnostic dilemma. The preliminary differential included entrapment of adnexal structures, collision with an adnexal neoplasm such as adenoid cystic carcinoma or metastatic adenocarcinoma. A colloidal iron special stain confirmed the deposition of mucin; however, a pankeratin AE1/AE3 immunohistochemical cocktail was surprisingly negative. Closer cytological examination of the discrete "glands" combined with nearby pseudoangiomatous (almost kaposiform) change hinted at melanocytic origin, which was confirmed with a positive melanoma antigen recognized by T-cells 1 immunohistochemical stain...

We present a 4-month-old infant with an eczematous halo around a congenital melanocytic nevus. After diagnostic excision, histopathologic examination revealed a Meyerson's nevus. This is a benign skin tumour that may show clinical signs of melanoma. It is therefore important to include Meyerson's nevus in the differential diagnosis of melanoma.

Meyerson phenomenon (MP) is characterized by a symmetrical area of erythema and scales encircling a central lesion, which is most commonly a banal melanocytic nevus. Herein, we describe an unusual case with MP representing an eczematized response to a melanoma in situ and review the literature covering this entity. A 56-year-old man presented with a 6-month history of a pruritic, pigmented lesion on the trunk. The patient had no other significant medical history and no notable family history of similar lesions...

Angel Fernandez-Flores, Marcela Saeb-Lima
Melanocytic nevi are frequently accompanied by inflammatory cells of different types, in varied amounts and distributed in different patterns. In the current report, we review the knowledge on inflammation seen in different types of melanocytic nevi. As an additional contribution, we studied the lymphocytic inflammatory component of Duperrat nevus, as well as the cytotoxic component of Sutton nevus, two contributions that we have not found in the literature. We conclude that: (a) Duperrat nevus has a mixed inflammatory reaction that includes histiocytes, foreign-body multinucleated giant cells, polymorphonuclears, lymphocytes (predominantly CD4+) and plasma cells (commonly abundant); (b) common melanocytic nevi with reactive inflammatory infiltrate usually show a CD4+ predominant population; (c) Meyerson nevus commonly shows an inflammatory infiltrate mainly made up of CD4+ T-cells; (d) Sutton nevus with halo phenomenon is accompanied by a dense inflammatory infiltrate with lymphocytes in a CD4:CD8 ratio varying from 1:1 to 1:3 and in which most of the CD8+ T-cells do not express cytotoxic markers; (e) Wiesner nevus commonly shows a spare lymphocytic infiltrate but the nature of the infiltrate has not yet been investigated...

Port wine stain (PWS, nevus flammeus) is a relatively common vascular malformation of postcapillary venules affecting 0.3 to 0.5% of newborn children. Since the mid-1990s, a case series and several case reports have described dermatitis on PWS corresponding to Meyerson phenomenon, usually reported in the setting of melanocytic nevi. There is no universal explanation of the cause or pathogenesis of eczema occurring in PWS, but it may be precipitated by atopic disease or vascular laser treatment of the malformation...

BACKGROUND: Meyerson's phenomenon is characterized by a symmetrical halo of erythema and scale around central, mostly melanocytic lesions. OBJECTIVE: Our aim was to describe the dermoscopic and reflectance confocal microscopy (RCM) features of melanocytic tumors less frequently associated with Meyerson's phenomenon, with histopathology and immunohistochemistry correlation. METHODS: Clinical, dermoscopic and RCM images of 4 histopathologically confirmed melanocytic tumors associated with Meyerson's phenomenon (3 dysplastic compound nevi and 1 melanoma) were retrospectively collected, with additional immunohistochemical analysis...

BACKGROUND: Eczematous (spongiotic) reaction in melanocytic lesions (Meyerson's phenomenon) has not been systematically analyzed and has not been convincingly documented in melanoma. METHODS: We analyzed 64 consecutive melanocytic lesions with spongiotic reaction, occurring in 57 patients (age range 14-81 years; mean, 39 years; 30 females, 27 males) including 16 common acquired nevi, 3 nevi with congenital features, 2 Spitz nevi, 29 dysplastic nevi, 6 in situ and 8 invasive melanomas...

Some types of melanocytic nevi are seldom mentioned in the literature and are therefore less well known. In the current study, we focus on the concepts of eponyms, synonyms, clinical presentation, and morphology of the following types: Meyerson nevus, cockarde (or cockade) nevus, Hori nevus, Sun nevus, Hidanos nevus, Duperrat nevus, Spark nevus, nevus spilus, eclipse nevus, Kerl nevus, and Kopf nevus.

Melanocytic nevi represent a widespread cutaneous finding. Nevertheless, the presence of mycosis fungoides and melanocytic nevi in the same location is an extremely rare event. We report the case of a patient affected by mycosis fungoides and treated with PUVA therapy, with complete remission of the disease. Eight years after therapy discontinuation, he presented epidermal scaling and an erythematous perinevic halo on 3 old melanocytic lesions, the clinical aspect of which was highly suggestive for Meyerson nevi...

BACKGROUND: Meyerson phenomenon (MP) consists of an eczematous reaction occurring around a pre-existing dermatologic lesion that is usually melanocytic and generally benign, and which is known as a Meyerson naevus. We report a case of multiple Meyerson naevi revealing melanoma, which itself was surrounded by a halo of eczema. PATIENTS AND METHODS: A 55-year-old man of phototype III with atopic eczema presented for pruritic eczema present for a fortnight, found solely on and around the naevi on his trunk and at roots of his limbs...

Meyerson's phenomenon is a well-documented inflammatory reaction described in a variety of cutaneous lesions, including the original description in nevocellular nevi (1). Such an inflammatory reaction was subsequently described in melanocytic and a sundry of nonmelanocytic lesions alike, including vascular malformations (2-11). We present three cases of infants with nevus sebaceus on the scalp, which were obscured by an eczematous, eosinophilic reaction reminiscent of that first described by Meyerson. Two of the patients had concomitant atopic dermatitis, but one had no association...

We present a case of a 49-year-old man who presented with a solitary atypical pigmented lesion with a surrounding halo of dermatitis. Dermoscopy showed a pigment network at the periphery with areas of scar-like depigmentation, negative pigment network and erythema. The lesion was treated preoperatively with a potent topical corticosteroid resulting in a reduction of inflammation. Histology showed an early Clark level 1 melanoma arising within a severely dysplastic compound melanocytic naevus. There was an adjacent perivascular chronic inflammatory cell infiltrate with occasional eosinophils...

Meyerson nevi occur whenever a rare focal and transitory eczematous eruption arises around melanocytic lesions. The same phenomenon has also been observed in non-melanocytic lesions as well. Herein we report the case of a 25 year old, male patient, who had noticed, two months before, the arising of a pruriginous and erithematous halo around two nevi localized on his abdomen. The lesions were found to be atypical on dermoscopic examination and he was submitted to surgical excision of both nevi. Histopathological examination revealed displastic compound melanocytic nevi, surrounded by intraepidermical vesicles and spongiosis...

Spontaneous regression of benign and malignant melanocytic lesions can be a visible sign of immunosurveillance. In this review, we discuss different immune reactions against melanocytic lesions: halo nevus, Meyerson's nevus, regression in melanoma and melanoma-associated depigmentation. These entities present with particular clinical aspects, histology and evolution. In all entities, a melanocyte-specific T-cell reaction has been assumed but a different degree of melanocyte destruction is present. A focus on the immune responses in melanocytic lesions reveals several aspects of an adequate skin immunity and may help to identify the key points in the immune destruction of melanocytes...

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...

BACKGROUND: Meyerson phenomenon is an uncommon clinical condition that is characterized by an eczematous halo surrounding a preexisting melanocytic nevus and numerous other lesions. The etiology of this condition is unknown. We suggest that the mechanism is due to the interaction between CD4 T lymphocytes and increased expression of intercellular cell adhesion molecule 1 (ICAM-1). OBJECTIVE: This article provides a concise overview of Meyerson phenomenon. METHODS AND RESULTS: We present the case of a 37-year-old female with an inflamed nevus located on her thigh from no evident cause...

To describe the characteristics of five pediatric patients with the Meyerson phenomenon associated with congenital melanocytic nevi, five cases were reviewed to retrieve information relating to clinical presentation, treatment and evolution of the eczematous phenomenon and of the nevi. Three of five patients were male. Mean age at presentation of the Meyerson phenomenon was 23 months (range: 4 mos-4 yrs). Three patients presented with only one halo eczematous lesion, while two patients presented with more then one halo eczematous lesions...

We undertook a clinical and histopathological analysis of patients presenting with Meyerson's naevi. Eleven patients with the characteristic histological features of a Meyerson's naevus were identified over a 5-year period. Diagnostic criteria included epidermal spongiosis and a dermal inflammatory infiltrate associated with a banal junctional or compound naevus. Cases were excluded if naevus cells showed moderate to severe atypia or regression. Patients were contacted by phone and interviewed regarding their lesions...
