Abstract

Purpose: To report a case of caruncular dacryops in a 58-year-old man that was excised in its entirety and to offer an immunohistopathologic analysis.

Methods: Sections stained with hematoxylin and eosin, periodic acid-Schiff, and Grocott methenamine silver (the latter 2 for identification of mucus) were evaluated, and immunohistochemical investigations were performed using cytokeratin (CK) 7, CK14, CK17, and smooth muscle actin.

Results: Histopathologic examination revealed a cystic dilation of the lacrimal gland ducts containing secretory globules. The ducts were composed of double-layered cuboidal epithelium with rare scattered goblet cells and interspersed prominent lobules of lacrimal gland tissue, diagnostic of dacryops. Immunohistochemistry of cystic ducts demonstrated a CK profile identical to that of the conjunctiva including the absence of a myoepithelium.

Conclusions: This is the first case of an intact caruncular lacrimal ductal cyst (dacryops). A previous report documented a spontaneously collapsed cyst with extrusion of secretory globoid bodies into extracellular space that elicited a foreign body giant cell response.
