[Rapid growth of eyelid squamous cell carcinoma in elderly patients with multiple cancers]

Two cases of squamous cell carcinoma of the eyelid are reported. Both patients had multiple cancers. Case 1 was an 81-year-old man who had a squamous cell carcinoma on his right upper eyelid and on his right palm, and Bowen's disease in his left thumb. Case 2 was an 87-year-old woman who had a squamous cell carcinoma on her right lower eyelid, an adenocarcinoma in her colon, and a uterus cancer of unknown histology. In spite of their advanced age, the eyelid tumors showed rapid growth in both cases. The reason for this rapid growth was unclear. However, the presence of cancers in other organs may provide clues, because the immunological ability in patients with multiple cancers is considered to be weakened.
