Hi Eline

This is what I found on it. It really does not say much, but kinda makes sense why they call it Bathing Suit Ichthyosis.I have also posted the link at the bottom of this artical where I found this info.

Autosomal recessive congenital ichthyosis is a heterogeneous group of disorders of cornification showing a wide spectrum of clinical phenotypes.Here, thirteen cases of a so far unreported distinct type of autosomal recessive congenital ichthyosis are described. All the skin lesions were present at birth and ten were then compatible with collodion baby. Shedding of the collodion led to an ichthyotic condition with a very characteristic distribution of the lesions which involved the trunk, the most proximal parts of the upper limbs, scalp and neck but spared the central face and extremities. The term "bathing-suit" ichthyosis is suggested for this unusual phenotype of lamellar ichthyosis.
