Abstract
ABSTRACT Li-Fraumeni syndrome (LFS) is caused by a pathogenic germline variant at the TP53 locus and is associated with an increased predisposition to a variety of cancers. The neoplasms most frequently associated with LFS are sarcomas, breast cancer, brain tumors, and adrenocortical carcinomas. In this case report, we present a 43-year-old male diagnosed with an ocular adnexal sebaceous carcinoma of the right upper eyelid who was confirmed to have LFS with subsequent genetic testing. The mutational profile of both the patient’s genetic screen and tumor sequencing were congruent, demonstrating the same pathogenic loss-of-function TP53 variant. This case report highlights the importance of pursuing genetic testing in patients with a history of multiple tumor types, particularly those with uncommon diagnoses. In this case, confirmation of LFS had important implications for personalized patient care, including identification of contraindicated treatment interventions and the imaging modalities necessary for vigilant follow-up screening.
