Multiple cutaneous neoplasms in a patient with Rothmund-Thomson syndrome: case report and published work review.

Rothmund-Thomson syndrome (RTS) is a rare genodermatosis characterized by early poikilodermatous skin lesions, often combined with juvenile cataracts, photosensitivity and bone defects. Data in the published work indicate that there is an increased risk of RTS patients developing malignant tumors. Herein, we report the multiple skin carcinomas observed in a case of RTS and review the published work on the occurrence of malignant tumors in these patients. We report the case of a 63-year-old male with RTS who developed multiple cutaneous neoplasms (three basal cell carcinomas, three squamous cell carcinomas and Bowen's disease) over the previous 15 years. A published work review confirmed that RTS is a genetic condition that predisposes subjects to the development of bone tumors, especially at an early age, and skin tumors at an adult age. Therefore, alongside careful osteoarticular monitoring to identify a bone tumor quickly, during the life of a patient suffering from the syndrome, it is just as important to take appropriate preventive action and monitor the possible onset of skin tumors.
