The patients were phenotypically identical twin can you do genetic testing with twins who were born healthy following a normal delivery. Neither the parents nor the other 3 siblings of the girls had any relevant medical history. The twins were brought to our unit at age 2 years for assessment of hyperkeratotic lesions on the hands, feet, and periarticular areas; there were no abnormalities of the mucosas or skin appendages.

Both girls presented the same clinical picture: thickening and hyperpigmentation of the skin on the hands and feet in a glove-and-stocking distribution as well as in periarticular areas, with superficial scaling in large sheets in some areas. There was also a local increase in fine vellus hair on the limbs Fig. Skin biopsy revealed a mild perivascular inflammatory infiltrate in the upper dermis.

The epidermis exhibited eosinophilic orthokeratotic hyperkeratosis with irregular epidermal acanthosis. The stratum granulosum presented intense vacuolization of keratinocytes, loss of intercellular junctions, and epidermal detachment. Large, irregular aggregates of anomalous keratohyalin granules were also observed Fig. Sequencing of the gene KRT2 chromosome 12q revealed a mutation that causes an amino acid change in the protein encoded by this gene.

Both patients presented a good is bird box really going to happen to topical emollient treatment and topical tazarotene 0. IBS is a rare, autosomal dominant disorder that was first described by Siemens 1 in There were no further reports of the condition untilwhen Traupe what is the main purpose of an abstract al.

Mutations in KRT2e are also expressed in the skin of the palms and soles, but, for reasons unknown, do not cause lesions in those areas. Mutations in KRT2e are expressed in the stratum granulosum and upper stratum spinosum, where they create a pattern known as epidermolytic hyperkeratosis, characterized microscopically by compact hyperkeratosis and vacuolar degeneration of keratinocytes with alteration of keratohyalin granules. This pattern is not pathognomonic, as it can also be found in other entities such as palmoplantar keratoderma Vörner type or what does business role mean acanthoma.

Incidental foci of epidermolytic hyperkeratosis can even arise in healthy skin. The main clinical and histologic differential diagnosis of IBS is bullous congenital ichthyosiform erythroderma CIEand the 2 conditions are easily confused. Bullous CIE is caused by mutations in the genes encoding keratin 1 or keratin 10, which are expressed deeper in the epidermis, in the suprabasal stratum spinosum. Whereas children with IBS are born healthy, children with bullous CIE are born with erythroderma and present a more severe clinical manifestations, including blister formation, extensive desquamation, and fluid and electrolyte abnormalities.

Our patients, being monozygotic twins, share the same genetic profile; therefore, they both carry the same mutation. Because IBS has an autosomal dominant pattern of inheritance, we hypothesize that our patients developed the disorder as a result of a spontaneous mutation that occurred in the zygote before its initial division. This hypothesis would explain how the mutation was transmitted to both girls. The treatment of IBS is can you do genetic testing with twins supportive, and includes topical emollients and keratolytics.

One of the most common complications of this disorder is the development of a secondary infection leading to pustulosis, which requires treatment with topical or systemic antibiotics. IBS is a relatively benign disorder whose clinical manifestations tend to stabilize and improve over time. The authors declare that they have no conflicts of interest.
