Dermatopathia Pigmentosa Reticularis Clinical Presentation
- Author: Noah S Scheinfeld, MD, JD, FAAD; Chief Editor: Dirk M Elston, MD more...
History
The primary clinical feature of dermatopathia pigmentosa reticularis is the occurrence of reticulate hyperpigmented macules at birth or in early childhood, usually by age 2 years.
The hyperpigmentation persists throughout life, showing no tendency of spontaneous fading. The reticulate network of hyperpigmented macules occurs particularly on the trunk, neck, and proximal areas of the limbs.
Physical
Most reported cases of dermatopathia pigmentosa reticularis have demonstrated a clinical triad of reticulate hyperpigmentation, mild nonscarring alopecia, and mild onychodystrophy. Other associated features may include the following:
- Punctate or diffuse palmoplantar hyperkeratosis
- Darkly pigmented nipples
- Nonscarring blisters on the dorsa of hands and feet following minor trauma or sun exposure
- Hyperhidrosis or hypohidrosis
- Adermatoglyphia (loss of dermal ridges on fingers and toes)
- Thin eyebrows and sparse pubic and axillary hair
It is possible that Naegeli-Franceschetti-Jadassohn syndrome (NFJS), poikiloderma Clericuzio type, and dyskeratosis congenita can overlap, with a presenation of prenatal growth retardation, postnatal growth retardation, developmental delay, microcephaly, and pigmentation pathology.[13]
Causes
Dermatopathia pigmentosa reticularis is believed to be a genetic disorder with probable autosomal dominant inheritance.[7]
