Harlequin ichthyosis (HI), which is the most severe genodermatosis, is caused by loss-of-function mutations in ABCA12, a member of the ATP-binding cassette transporter family. To investigate the pathomechanism of HI and the function of the ABCA12 protein, we generated ABCA12-deficient mice (Abca12(-/-)) by targeting Abca12. Abca12(-/-) mice closely reproduce the human HI phenotype, showing mark...

The ABCA12 gene encodes an ATP-binding cassette transporter vital to skin barrier function. In keratinocytes, transports ceramides into the lumen of lamellar bodies as part widely conserved water system. Alterations in are associated with autosomal recessive congenital ichthyoses: harlequin ichthyosis, non-bullous ichthyosiform erythroderma, and ichthyosis. We report a 4-month-old female who pr...

Ichthyoses are a heterogeneous group of cutaneous keratinization disorders that can be congenital or acquired. Apart from neoplastic disorders, the acquired form of ichthyosis (AI) has been associated with a variety of diseases including infections, autoimmune/inflammatory and endocrine/metabolic diseases as well as nutritional conditions, medications and others. However, malignancy accounts fo...

Arthrogryposis-renal tubular dysfunction-cholestasis syndrome is a rare multisystem disorder, originally described in 1973 and to date only 62 patients have been reported. Herein, we reported on a neonate with arthrogryposis-renal tubular dysfunction-cholestasis syndrome presenting very early after birth. Recurrent febrile illnesses, failure to thrive, ichthyosis, hypothyroidism, and bilateral ...

We describe a unique presentation of cervical verrucous carcinoma (VC) associated with ichthyosis the uterine cavity in an 80-year old woman. Areas transition from giant condyloma (GC) were present VC. This paper also includes review relevant literature. VC cervix is uncommon malignancy, and GC to interesting finding, confuting theory that they represent distinct entities, different risk factor...
