Abstract
A 9-year-old girl presented with a congenital, blue-purple, partially compressible plaque with a cobblestone surface on the left lateral foot and ankle. Similar, solitary, blue nodules later appeared elsewhere on the extremities. The lesions were tender to palpation and were associated with spontaneous paroxysms of pain and paresthesias. Histopathologic evaluation of a skin biopsy specimen showed rows of glomus cells that surrounded thin-walled vascular channels, which confirmed the diagnosis of glomuvenous malformations. This autosomal dominant condition, which is due to mutations in the GLMN gene, presents with clinical findings that are distinct from those of familial, multiple, cutaneous and mucosal venous malformations. Treatment options include excision, sclerotherapy, and laser therapy (ablative or pulsed dye).
