A Rare Case of Giant Dacryocystomucopyocele

Chronic dacryocystitis is frequently caused by Naso Lacrimal Duct (NLD) infection or obstruction. Mucocele is formed when chronic stagnation of tears occurs in the lacrimal sac. When mucocoele gets infected with pyogenic organisms, pyocele is formed. Proximal obstruction in mucopyocele causing encysted dacryocystomucopyocele presenting as an enormous swelling is very uncommon. Very few cases of giant encysted dacryocystomucopyocele are reported in literature. The authors report a 42-year-old male with an acquired, enormous dacryocystomucopyocele, which developed over only one and half years and produced upward displacement of the lower lid and mechanical obstruction for eye closure. Computed tomography of orbit and paranasal sinuses was done to confirm the diagnosis and find out the extent of cyst. Complete surgical excision of the cyst was performed. There was no recurrence of the swelling at last follow-up at 1 year.
