Mucoepidermoid Carcinoma of the Palpebral Conjunctiva

Purpose: We report our experience with a case of a nodular lesion of the lower palpebral conjunctiva with histologic features consistent with mucoepidermoid carcinoma. Methods: A 72 year-old man presented with a left lower palpebral conjunctiva lesion. 3X3 mm sized flat pedunculated yellowish red mass was observed. Incisional biopsy proved the mass a mucoepidermoid carcinoma and wide local resection was conducted. Results: Hematoxylin and eosin-stained sections showed lobules of tumor cells, consisting of predominantly epidermoid cells and scattered islands of mucin-secreting cells. Mucicarmine-stained sections demonstrated strong positivity, consistent with the diagnosis of mucoepidermoid carcinoma. Conclusions: In any case presenting palpebral conjunctival lesion, mucoepidermoid carcinoma should be differentiated, and it is necessary to confirm the diagnosis through biopsy.
