X-linked reticulate pigmentary disorder is an extremely rare skin disease described in only four families to date and characterized in males by diffuse reticulate brown hyperpigmented skin lesions developing in early childhood and a variety of systemic manifestations (recurrent pneumonia, corneal opacification, gastrointestinal inflammation, urethral stricture, failure to thrive, hypohidrosis, digital clubbing, and unruly hair and flared eyebrows), while in females, there is only cutaneous involvement with the development in early childhood of localized brown hyperpigmented skin lesions following the lines of Blaschko. This disease was first considered as a cutaneous amyloidosis, but amyloid deposits are an inconstant feature. |

A rare mosaic form of Legius syndrome with findings typical of Legius syndrome, namely multiple cafe-au-lait macules (CALMs) with or without axillary or inguinal freckling. Mosaic form is caused by postzygotic pathogenic variants in SPRED1 gene. In mosaic Legius syndrome the allelic/tissue distribution of the pathogenic SPRED1-variant clearly suggests mosaicism and/or the distribution of CALMs is segmental. The phenotype can be milder than in Legius syndrome. |
