Acral mucinous syringometaplasia. A benign cutaneous lesion associated with verrucous hyperplasia.

We describe herein a case of acral mucinous syringometaplasia that presented clinically as a verruca plantaris. Microscopically, verrucous hyperplasia of the epidermis and central, dilated eccrine ducts lined by a mixture of squamous and goblet cells were present. Mucinous syringometaplasia is a benign entity that should be distinguished from other mucin-containing cutaneous lesions.
