A rare X-linked dominant disorder with a characteristic unilateral (one-sided) inflammatory and ichthyosiform nevus, along with limb defects on the same side.
A rare neuroectodermal syndrome where ichthyosis is associated with colobomas, heart defects, mental retardation, and ear abnormalities.
A presentation at birth where the infant is encased in a tight, shiny, translucent membrane resembling collodion, which sheds to reveal an underlying ichthyosis.
A form of ichthyosis present at birth with generalized redness (erythroderma) and fine, white, superficial scales.
A form of chondrodysplasia punctata with a characteristic swirled or linear pattern of ichthyosiform erythroderma and scaling along Blaschko's lines.
A genetic ichthyosis presenting at birth with blistering and erythroderma that evolves into severe, dark, verrucous (wart-like) hyperkeratosis, especially in flexures.
A genetic ichthyosis presenting at birth with blistering and erythroderma that evolves into severe, dark, verrucous (wart-like) hyperkeratosis, especially in flexures.
A genetic disorder with two distinct features: persistent, figurate, red-brown hyperkeratotic plaques and transient, migratory annular erythematous patches.
The most severe form of congenital ichthyosis, where infants are born with massive, thick, armor-like plates of scale that severely restrict movement.
A rare variant where hundreds of small, confetti-like spots of normal-appearing skin emerge from the background of ichthyotic skin.
A term for a group of ichthyoses with dramatic, spiny, or porcupine-like hyperkeratotic scales.
The most common form of ichthyosis, presenting in early childhood with fine, white, 'fish-like' scales that characteristically spare the flexural areas.
A syndrome of Keratitis (of the eye), Ichthyosis, and Deafness, presenting with hyperkeratotic skin plaques and sight-threatening eye changes.
A congenital ichthyosis that evolves into large, dark, plate-like scales covering the entire body.
A genetic disorder characterized by congenital ichthyosis, atopy, and a specific hair shaft defect (trichorrhexis invaginata or 'bamboo hair').
A rare metabolic disorder causing a non-bullous congenital ichthyosis along with storage of neutral lipids in various tissues, leading to myopathy.
A metabolic disorder of phytanic acid metabolism that causes a mild, ichthyosis vulgaris-like scaling along with retinitis pigmentosa, neuropathy, and ataxia.
A metabolic disorder causing a congenital ichthyosis with fine, generalized scaling, spastic paralysis, and intellectual disability.
A metabolic disorder causing a congenital ichthyosis with fine, generalized scaling, spastic paralysis, and intellectual disability.
Also known as X-linked ichthyosis, this affects males and presents with prominent, dark, 'dirty' scales on the neck, trunk, and extensor surfaces.
A milder form of epidermolytic ichthyosis with superficial blistering and a characteristic 'mauserung' (molting) phenomenon.
A group of genetic disorders characterized by sulfur-deficient, brittle hair that shows a 'tiger tail' pattern under polarizing microscopy, along with ichthyosis.
This affects males and presents with prominent, dark, 'dirty' scales on the neck, trunk, and extensor surfaces, characteristically sparing the flexures.
