Case 2

Orange caruncular mass in a 43 year old null Oncyocytoma. Note the abundant eosinophilic cytoplasm and cystic nature of the tumor which is morphologically similar to oncyocytoma of other anatomic sites. The caruncle is histologically distinct as it is lined by conjunctival epithelium but contains subepithelial adnexal elements such as hair follicles and sebaceous glands.

50 year old morbidly obese gentleman with obstructive sleep apena and eyelid laxity. Aja51 Papillary conjunctivitis in a patient with floppy eyelid syndrome. There is marked hyperplasia of the conjunctival epitheilum with promient subepithelial fibrovascular proliferation and intraepithelial neutrophils.
