Familial atrophia maculosa varioliformis cutis: an ultrastructural study.
Atrophia maculosa varioliformis cutis is a rare and distinctive form of idiopathic facial macular noninflammatory atrophy that may rarely be observed in members of the same family. We describe two brothers, ages 14 and 16 years, with spontaneously appearing, asymptomatic, varioliform and linear atrophic lesions. Their past medical history was positive for varicella occurring in childhood without residual facial scarring. Routine laboratory investigations and screening for circulating autoantibodies were negative. Both patients were concordant for HLA A2 and DQ4.1. Routine and ultrastructural histologic examination of a punch biopsy specimen showed the presence of scarce, small, fragmented elastic fibers and compact collagen bundles associated with hypertrophic fibroblasts in the dermis. Our patients remained clinically stable, untreated, over a 2-year follow-up period. No long-term follow-up data have previously been reported.
