[Foreign body granuloma resulting from a lacorhinostomy tube's migration associated with actinomycosis of the lacrimal sac].

INTRODUCTION

Lacorhinostomy is a surgical procedure that establishes a permanent communication between the caruncular region and the nasal fossa using a fixed tube. The main complications involve the biotolerance of this tube.

OBSERVATION: Fifteen years after lacrimal surgery, a patient presented with repeated canthal inflammation associated with epistaxis on the same side. The anterior rhinoscopy showed an occlusion of the inferior meatus by a mucous tumor, bleeding to the contact. A lacrimal sac scan disclosed a local tumor without bone erosion. With an endonasal dacryocystorhinostomy, a lacorhinostomy tube was found hidden in the canthal region associated with actinomycosis of the lacrimal sac.

DISCUSSION: Lacrimal actinomycosis is mostly primitive, although actinomycosis in other locations may be associated with the presence of a foreign body. In that case, the association is probably a coincidence.

CONCLUSION

When a tumor develops after lacrimal surgery, a foreign body reaction must be suspected.
