Rombo syndrome in Child
Vermiculate atrophoderma and reddish-blue skin discoloration usually appear during childhood (between the ages of 7 and 10 years) and become more overt with time. Facial telangiectasias and other disease manifestations subsequently ensue, with BCCs appearing in the third or fourth decade. A single patient in the initial kindred also manifested trichoepitheliomas. A subsequent patient was noted to have numerous vellus hair cysts. While the original description of Rombo syndrome documented milia clinically, some of these lesions contained vellus hairs on biopsy.
The underlying gene defect is unknown. Biopsies from an affected patient showed marked solar elastosis. This together with the early onset of BCCs has led to the theory that the culprit gene may be involved in cell cycle regulation or DNA repair. Others, however, have speculated that the affected gene is involved in follicle growth and differentiation.
