Visceral malignancies are common in patients with periocular sebaceous cell carcinoma. Approximately one in eight demonstrated a heritable risk for further visceral malignancy through failure to express DNA mismatch repair proteins. Diagnosis of periocular sebaceous cell carcinoma should prompt physicians to search for other associated malignancies. Immunohistochemical characterisation of these sebaceous lesions is useful in identifying increased risk in affected patients and family members.
