Elastic nevus with normal expression of elastin and elastin-related proteins mRNAs.
A 3-year-old Japanese girl presented with disseminated white papules on the trunk. A biopsied specimen of the lesional skin revealed a focal accumulation of elastic fibers in the mid to deep dermis. No skeletal involvement was detected. This case was considered to be elastic nevus without systemic involvement. Since an elevated elastin expression in the fibroblasts of typical Buschke-Ollendorff syndrome (BOS) has been reported, elastin and elastin-related protein mRNA levels in the cultured patient fibroblasts were determined. There were no significant differences of steady-state levels of elastin, fibrillin 1 and microfibril-associated glycoprotein 1 mRNAs between patient and matched control fibroblasts. Elastic nevus without skeletal involvement may be etiologically different from typical BOS.
