Conjunctival Granuloma Caused by an Unknown Metallic Foreign Body

Abstract

Introduction: Conjunctival granulomas are tumor pathologies of various origins. A foreign body, whatever its nature, is often involved in its genesis. To date, there is very little data on foreign body conjunctival granulomas, the prevalence would be approximately 10% and their underestimation is probably linked to the inconsistency of their clinical presentation. Patient and Observations : We report a case of conjunctival granuloma caused by a metallic foreign body that went unnoticed in a young boy, the interest of rigor on primary protection measures for high-risk occupations, and of the strict application of the diagnostic protocol relating to ocular trauma. Discussion: foreign body granulomas, despite their usually harmless nature, can jeopardize the anatomical and functional prognosis of the affected eye. Only a detailed interview and a meticulous clinical examination allow the diagnosis to be made and the distinction to be made with conjunctival granulomas of different causes. Conclusion: the possibility of the involvement of a foreign body in the genesis of conjunctival granulomas must impose the rigorous application of diagnostic and therapeutic protocols.
