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. |

Thumb deformity-alopecia-pigmentation anomaly syndrome is a rare, genetic, congenital limb malformation syndrome characterized by short stature, sparse scalp hair, hypoplastic, proximally placed thumbs, and skin hyperpigmentation with areas of raindrop depigmentation. Presence of a single, upper central incisor has also been reported. There have been no further descriptions in the literature since 1988. |

Extrasystoles-short stature-hyperpigmentation-microcephaly syndrome is a rare, genetic, malformation syndrome with short stature characterised by microcephaly, borderline intellectual disability, hyperpigmentation of the skin, short stature, and ventricular extrasystoles. Cardiac syncope may also be associated. There have been no further descriptions in the literature since 1975. |

A rare genetic disease characterized by the presence of multiple café-au-lait macules and elevated rates of sister chromatid exchange demonstrated on cytogenetic testing. Pre- and postnatal growth deficiency with short stature, microcephaly, mild developmental delay, cardiomyopathy, and symptomatic gastro-esophageal reflux have also been described, while malar rash is typically absent. |
