There are many benign skin neoplasms encountered in dermatopathology practice that can be associated with underlying genetic disorders. Although benign themselves, these lesions can offer insight into the potential for development of internal malignancies in patients with these hereditary syndromes. An astute dermatopathologist will recognize clues that suggest a syndromic association of these lesions, such as the presence of multiple lesions, distinct histologic growth patterns, and the results of ancillary immunohistochemical testing. The dermatopathologist can then guide the referring clinician to obtain additional clinical and family history and, if appropriate, pursue further screening and genetic testing. This review article will provide an overview of the clinical and histologic features associated with select common and uncommon benign skin neoplasms with syndromic associations.
