Epidermoid carcinoma of the lacrimal sac: a clinicopathological case report

Epidermoid carcinomas of the lacrimal sac are rare. We report a case that illustrates the difficulties in their diagnosis. When the diagnosis was made in our patient the tumour had extended beyond the sac wall and treatment was unsuccessful. The prognosis of these tumours depends on early diagnosis and complete excision, which demands a high degree of suspicion in all cases of chronic tearing, chronic dacryocystitis or a nonreducible mass in the area of the lacrimal sac. Consultation with an otolaryngologist is esential in both diagnosis and management.
