Systematized verrucous epidermal nevus partially responsive to acitretin: A case report

@#<p style="text-align: justify;">A 5-year-old female presented a 4-year history of generalized well-demarcated asymptomatic brown to dark brown thin verrucous plaques with a Blaschkoid distribution. Histopathology was consistent with an epidermal nevus. Patient was diagnosed to have systematized verrucous epidermal nevus. Due to the extent of the lesions, surgical management was not feasible. Hence acitretin was given which showed partial decrease in the thickness of the lesions.</p>

A Case of Systematized Inflammatory Linear Verrucous Epidermal Nevus with Mandibular Hypoplasia / 대한피부과학회지

Inflammatory linear verrucous epidermal nevus (ILVEN) is an uncommon variant of verrucous epidermal nevus, clinically characterized by erythematous and hyperkeratotic verrucous papules with a typical linear arrangement. Most reported cases present as solitary lesions, but systematized ILVEN is rare. Epidermal nevus syndrome is a congenital disorder in which epidermal nevi are associated with abnormalities in other organ systems. However, ILVEN has been reported rarely in association with such abnormalities, including those of the skeleton. Here we report a rare case of systematized ILVEN presenting with concomitant mandibular hypoplasia.

Systematized Inflammatory Linear Verrucous Epidermal Nevus / 대한피부과학회지

Inflammatory linear verrucous epidermal nevi (ILVEN) were first described in the literature, in 1971, by Altman and Mehregan. Most cases were reported as solitary lesions. In contrast, systematized ILVEN, involving wide areas of the integument, has only rarely been reported. A variety of treatment modalities has been reported, ranging from topical medications, such as potent corticosteroids or tretinoin 0.1% to variable procedures, including CO2 and pulsed dye laser, cryotherapy, and surgical excision. However, multifocal skin lesion is more difficult to treat. An 8-year old boy was presented with an extensive thick scaly plaques and patches, affecting the trunk and the four extremities sparing face. It developed when he was 3 years old, and he complained pruritus. On physical examination, linear, or whirl-like scaly plaques were seen, along with Blaschko lines. Pathologic finding was in accordance to ILVEN. We treated him with topical calcipotriol, tacrolimus and systemic acitretin. After 8 months, the lesion and symptoms improved.

Porokeratotic eccrine ostial and dermal duct nevus.

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare variant of porokeratosis with characteristic histological feature of cornoid lamella involving the acrosyringium. We report a classic case of a 20-year-old male, who clinically presented to us with keratotic papules and plaque with pits, few having comedo like plugs, on right palm and sole since 1 year of age. A punch biopsy from palm was diagnostic as well as confirmatory showing cornoid lamella involving an eccrine duct which is the characteristic histopathological feature of PEODDN.

Nevus epidérmico lineal con hiperqueratosis epidermolítica: descripción de caso / Linear epidermal nevus with epidermolytic hyperkeratosis case description

Introducción: El nevus epidérmico es una anomalía del desarrollo epidérmico que puede afectar cualquier parte del cuerpo, aunque se cita el predominio en las extremidades. Si bien esta entidad no es infrecuente, la presencia de hiperqueratosis epidermolítica en la biopsia cutánea es un hallazgo relativamente poco común, como lo demuestra la literatura consultada.Caso Clínico: Presentamos el caso de un paciente de sexo masculino de dos años de edad, con el diagnóstico de nevus epidérmico verrugoso lineal unilateral afectando el hemicuerpo izquierdo, con evidencias histopatológicas de hiperqueratosis epidermolítica. Discusión: El nevus epidérmico lineal unilateral es una forma rara de nevus epidérmico y también es inusual la presencia de hiperqeratosis epidermolítica. Se presenta generalmente dentro de los 5 primeros años de vida y las lesiones son intensamente pruriginosas. Estos nevos son frecuentemente refractarios al tratamiento tópico y la extirpación quirúrgica puede ser una opción para mejorar los síntomas.

Introduction: Epidermal nevus is an anomaly of epidermal development that can affect any part of the body, although usually reported in the extremities. Although it is not uncommon, the presence of epidermolytic hyperkeratosis on skin biopsy is a relatively uncommon finding in the literature. Case report: We report the case of a 2-year old male diagnosed with unilateral linear verrucous epidermal nevus of the left hemisphere with histopathological evidence of epidermolytic hyperkeratosis. Comments: Unilateral linear epidermal nevi are a rare form of epidermal nevus, and are also unusual in the presence of epidermolytic hyperkeratosis. They usually occur within the first 5 years of life and the lesions are intensely itchy. These nevi are often refractory to topical therapy and surgical removal may be an option to improve symptoms.

Nevo epidérmico inflamatorio lineal (NEVIL): Presentación en la edad adulta / Inflammatory linear verrucous epidermal nevus (ILVEN): Late onset disease

El NEVIL es la variedad inflamatoria del nevo epidérmico; es un tumor benigno hamartomatoso, que se distribuye siguiendo las líneas de Blaschko. Estas líneas representarían mosaicismos cutáneos del desarrollo embriológico. El NEVIL suele aparecer en la infancia. Son generalmente unilaterales y en ocasiones muy pruriginosos. El diagnóstico diferencial es frecuentemente dificultoso. Presentamos una paciente en la cual la manifestación de esta patología se produce en forma tardía, siendo esto poco frecuente. El tratamiento es un desafío, se han probado múltiples modalidades terapéuticas, con resultados en ocasiones desalentadores. La cirugía, puede utilizarse en lesiones de pequeño tamaño. Los tratamientos con luz láser podrían ser de utilidad.

The ILVEN is the inflammatory variety of epidermal nevi, benign hamartomatous tumor that distributed following Blaschko lines. These lines represent cutaneous mosaicism in embryologic development. The ILVEN usually appear in the infancy. Generally unilateral and occasionally is very pruriginous. The differential diagnosis is often difficult. We present a patient in which the manifestation of her disease is produced in late onset, being this infrequent. Management is a challenge, multiple therapeutic modalities have been tested, with discouraging results. Surgery can be utilized in small size lesions. Laser therapy could be of utility.

A Case of Verrucous Epidermal Nevus Contiguous with Nevus Sebaceus / 대한피부과학회지

During normal development of skin, pluripotential cells give rise to keratinocytes, sebaceus glands, hair follicles, apocrine glands, and eccrine glands. In epidermal nevi, these components emerge in an abnormal mixture within a circumscribed site. Many authors have categorized epidermal nevi according to their predominant component, however, there is often notable overlap which occurs within a single area or within contiguous areas. An 11-year-old female patient presented with linearly-arranged, multiple yellowish papules and a dark-brown colored verrucous plaque on the left occipital area, which had been present since birth. From the histopathological findings, the papules were diagnosed as nevus sebaceus and the plaque was diagnosed as verrucous epidermal nevus. Our present case gives support to the view that epidermal nevi have a spectrum of manifestations, including verrucous epidermal nevi and nevus sebaceus. To the best of our knowledge, this is the first report of a verrucous epidermal nevus contiguous to a nevus sebaceus in the Korean dermatological literature.

A Case of Inflammatory Linear Verrucous Epidermal Nevus Occurring in the Left Temporal Scalp / 대한피부과학회지

Inflammatory linear verrucous epidermal nevus(ILVEN) is a rare variant of epidermal nevus characterized by an early age of onset, an unilateral pruritic inflammatory psoriasiform lesion, and relative refractoriness to treatment. It has been reported that ILVEN mainly occur in the lower extremities but develop in the upper extremities, neck and trunk. Herein, we present a case of ILVEN occurring in the left temporal scalp of a 32-year-old woman which, in our review of literature, has not been reported as a development site.

A Case of Inflammatory Linear Verrucous Epidermal Nevus

Inflammatory linear verrucous epidermal nevus(ILVEN) is a relatively rare skin disorder, characterized by chronic inflammatory psoriasiform pattern. This chronic skin disorder is generally believed to be resistant to various treatments, although some authors have reported success with 13-cis-retinoic acid and 585 nm pulsed laser therapy. We experienced a 15-month aged female ILVEN patient who has been suffered from linear erythematous verrucous pathes mainly located on left inguinal area, hand, and foot with persistent itching sense. This skin lesion have been developed at birth, and more spread out toward right extremity after 1 year old age . We initially treated this skin lesion with topical corticosteroids and oral anti-histamines, but this treatment was not successful. So we retreated this patient with etretinate(oral retinoid) and topical 13-cis-retinoic acids, we found that therapeutic responses to these applications were more remarkable. Now, we closely observe this patient's clinical course further more.

A Case of Inflammatory Linear Verrucous Epidermal Nevus Combined with Generalized Pasoriatic Eruption / 대한피부과학회지

A 5- year old female patient visited our clinic due to linear erythernatous and verrucous patches on the left extremities of 3 years duration, She was born with a small erythematous macule on the lateral side of left little finger. This macule, over 2 years, developed into pruritic, linear, and verrucous patches stretching from left little finger to lefr, axillai y area, and also erythematous, linear patches on the left thigh. On follow-up visit on October 1986, she has generalized psoriatic eruption with aggravation of originnl skin lesions. Digriosis was based on the clinical features and histopathnlogic findings of the skin lesions.
