Résumé
A hiperceratose epidermolítica é uma forma de ictiose geralmente resistente a tratamentos tópicos. Relata-se um caso de paciente feminina , em acompanhamento na dermatologia desde 1978, com diagnóstico de hiperceratose epidermolítica. Foi tratada inicialmente com queratolíticos, vitamina A oral, ácido tartárico e emolientes tópicos, porém sem melhora no quadro clínico, já que não haviam disponíveis outros tratamentos na época. Em 1986, com o advento dos retinóides orais, foi introduzido o etretinato, e em 1998, foi substituído pelo acitretin, apresentando excelente resposta terapêutica. No momento a paciente está em uso de acitretin 25 mg/dia, completando 23 anos de uso de retinóides orais, com mínimos efeitos adversos e melhora significativa na qualidade de vida.
Epidermolytic hyperkeratosis is a form of ichthyosis normally resistant to topical treatments. Female patient monitored since 1978 diagnosed with epidermolytic hyperkeratosis. Clinical examination showed generalized hyperkeratosis and scaling. Given that no other treatments were available at the time, the patient was initially treated with keratolytic, systemic vitamin A and moisturizers, with no improvement. In 1986, with the development of oral retinoids, etretinate was introduced. In 1998 this was replaced by acitretin. The patient is receiving 25 mg/day after 23 years of using oral retinoids. Significant improvement of the condition and patient's quality of life has been noted.

In 1937, Siemens described a Dutch family with superficial blistering, flexural hyperkeratosis, and characteristic mauserung appearance. Since then, less than 20 kindreds with this condition have been described in the English dermatologic literature. A 14-year-old boy presented with history of recurrent blistering and peeling of skin since the age of 1 month, predominantly seen over limbs and trunk, often associated with secondary infection. His mother also had similar symptoms from childhood. On examination, the child had typical mauserung peeling of the skin and dirty gray hyperkeratosis in a rippled pattern over flexures. Skin biopsy from the boy showed intracorneal blistering with epidermolytic hyperkeratosis in the upper spinous layers. The typical history and clinical features along with characteristic histological findings confirmed our diagnosis of ichthyosis bullosa of Siemens. It must be differentiated from other conditions with epidermolytic hyperkeratosis and skin peeling, such as bullous ichthyosiform erythroderma of Brocq and peeling skin syndrome. Our patient responded well to 0.05% topical tazarotene gel over four weeks.

La eritrodermia ictiosiforme congénita ampollar constituye una forma rara de ictiosis de carácter autosómico dominante, que presenta eritema generalizado y ampollas desde el nacimiento, que posteriormente son reemplazadas por escamas gruesas, oscuras y adherentes, predominando en flexuras. El tratamiento de esta condición puede resultar muy difícil. Si bien los retinoides sistémicos constituyen el tratamiento de elección para los trastornos de la queratinización, las dosis elevadas pueden desencadenar fragilidad cutánea y formación de ampollas. Se discute el uso de acitretin y los efectos secundarios en esta forma de ictiosis
