Abstract

Collagenomas, or connective tissue nevi of the collagen type, are hamartomatous growths of otherwise normal collagen. They are divided into two groups: the inherited form that contains familial cutaneous collagenoma and shagreen patches in tuberous sclerosis, and the acquired form that contains eruptive collagenoma and isolated collagenoma. Among them, isolated plantar collagenoma with a cerebriform appearance is a relatively rare type of connective tissue nevus. It has been described as one of the major skin findings in Proteus syndrome. We present an unusual case of acquired isolated plantar collagenoma presenting as cerebriform hyperplasia, which was not associated with Proteus syndrome.
