  Abstract 

Erythrokeratodermia variabilis is a rare keratinization disorder characterized by two types of skin lesions, stationary hyperkeratotic scaly plaques, and migratory erythematous bizarre patches. Herein, we report a case of a 5-year-old female child who presented with pruritic well-defined, reddish brown hyperkeratotic plaques on trunk, axillae, neck, and extremities in bilaterally symmetrical distribution and had shown excellent improvement with isotretinoin.

  Introduction Top


Erythrokeratodermia variabilis (EKV), first described by Mendes de Costa in 1925, is a rare genetic ichthyosiform disorder.[1] It is characterized by two types of cutaneous lesions, erythematous patches that assume well-demarcated bizarre geographic configurations and hyperkeratotic plaques with the generalized distribution.[2]


  Case Report Top


A 5-year-old female child, born of nonconsanguineous marriage, adequately immunized for her age, was brought by parents with complaints of itchy, red scaly lesions on the body that started at the age of 1-year. The lesions initially appeared on the trunk then sequentially spread to the neck, axillae, and both upper and lower extremities. There was a history of frequent change of size and location of the redness. History of seasonal exacerbation of lesions in winter was present. She was born by normal vaginal delivery at term. History of birth in parchment-like membrane was absent. No history of atopy was present. None of the family members had similar complaints.

Cutaneous examination revealed multiple well-demarcated, reddish brown, bilaterally symmetrical, hyperkeratotic scaly plaques on the neck, shoulder, axillae, lower abdomen, groin, and back [Figure 1]a and [Figure 1]b. Diffuse erythema and scaling were present on bilateral upper, lower extremities, and face [Figure 1]c and [Figure 1]d. Palms and soles were thickened and hyperlinear. The hair, nails, teeth, and mucous membrane appeared normal. The remainder of the physical examination revealed no abnormalities. Potassium hydroxide examination of scales did not show fungal elements. All hematological and biochemical parameters including serum lipid profile were within normal limits.

A biopsy taken from hyperkeratotic plaque revealed compact orthokeratotic hyperkeratosis, acanthosis, and mild lympho-histiocytic infiltrate in the upper dermis [Figure 2].

On the basis of clinical features and histopathology, a diagnosis of EKV was made.

The patient was treated with topical emollients and oral isotretinoin 20 mg daily for 3 months with excellent improvement [Figure 3]. A maintenance dose of 10 mg/day isotretinoin was continued for another 5 months during which patient remained in remission. At present, she is on 10 mg alternate day oral isotretinoin for 4 months without any recurrence.

  Discussion Top


EKV is a rare autosomal dominant disorder of keratinization. There is a mutation of the gene GJB3 or GJB4, coding for a gap junction protein connexin 31 and connexin 30.3, respectively.[3],[4]

The disease presents at birth or within 1-year of age. The lesions have two types of morphological features, the first type is stationary hyperkeratotic plaques and the second type is transient erythematous patches. First, the hyperkeratotic plaques are well-defined, relatively fixed in position and have a predilection for the extremities, buttocks, and trunk as found in our case. Second, the transient erythematous patches have a polycyclic configuration that change size and shape over minutes to hours or involute completely. These lesions are more common on the face, buttocks, and extensor surfaces. Both types of lesions may be precipitated by either trauma or changes in temperature.[5] Approximately 50% of patients display a palmoplantar keratoderma associated with peeling.[2]

Rare EKV variants include erythroderma en cocardes, known as Degos' disease, reticulate erythrokeratoderma and EKV with erythema gyratum repens-like lesions.[6],[7],[8] The course of the disease is chronic, with remissions and exacerbations throughout life.

Differential diagnoses considered in our case were EKV, Netherton syndrome, and nonbullous congenital ichthyosiform erythroderma (NBCIE). The absence of linear ichthyotic plaque, atopy, and hair abnormality ruled out netherton syndrome. The absence of collodion membrane at birth, positive history of migratory erythema, and the presence of hyperkeratotic reddish brown plaques on classical sites ruled out NBCIE.

Topical emollients and systemic retinoids such as acitretin or isotretinoin are the first line of treatment.[9],[10] The major advantage to the long-term use of isotretinoin is its short half-life and simplifying dose changes. The recommended starting dose of isotretinoin is 0.5–0.75 mg/kg/day. A response is apparent within 2–3 weeks and the maintenance dose is titrated down to the lowest effective level between 0.1 and 0.5 mg/kg/day. Other topical agents such as salicylic acid, urea, and topical tazarotene are also helpful.
