Squamous Cell Carcinoma of the Caruncle.

Squamous cell carcinoma (SCC) of the lacrimal caruncle is a rare entity. The authors report the management and outcomes of 3 cases of caruncle SCC. Case 1 underwent wide margin surgical excision with adjuvant topical chemotherapy for a poorly differentiated SCC. He later developed regional lymph node metastasis and required modified radical neck dissection. Case 2 underwent wide margin surgical excision with cryotherapy and adjuvant topical chemotherapy for an invasive moderately differentiated SCC. She later developed a recurrence and underwent orbital exenteration. Case 3 was a moderately differentiated SCC treated with wide margin excision alone and had no recurrence during 5-year follow up. Careful surveillance of caruncle SCC is required, given the observed propensity for local recurrence and/or regional metastasis.
