Pseudoadenomatous hyperplasia of the conjunctiva

Purpose: To describe the clinical and pathologic features of three patients with pseudoadenomatous hyperplasia of the conjunctiva. Design: Methods: Observational case series with clinicopathologic correlation. Case reports and clinical histories and examination of three biopsy specimens. Main Outcome Measures and Results: Pseudoglandular hyperplasia of the conju nctiva was associated with chronic inflammation, including eosinophils, in two patients, and squamous epithelial hyperplasia in a third. The pseudogla nds are lined by varying proportions of squamous epithelium and goblet cell s. Conclusions: Pseudoglandular hyperplasia of the conjunctiva can mimic a wel l-differentiated mucoepidermoid carcinoma. Awareness of this entity may hel p to prevent misdiagnosis and unnecessary surgery. Ophthalmology 2001;108:1 35-138 (C) 2001 by the American Academy of Ophthalmology.
