LEON RODRIGUEZ, Yereyni et al. Corneal dellen secondary to epidermoid carcinoma of the conjunctiva. Rev Cubana Oftalmol [online]. 2018, vol.31, n.4, pp. 88-92. ISSN 1561-3070.

Corneal dellen is an area of localized corneal thinning as a result of dehydration caused by lack of humectation associated to an adjoining conjunctival bulging. Here is a 72-years old Caucasian woman with a history of hypertension, who presented continuous tearing and feeling of a foreign body in her left eye during a week. The biomicroscopic exam showed fibrovascular tissue in nasal bulb conjunctiva, which infiltrated into the cornea, it was raised of flat surface, unkeratinized, accompanied with conjunctival injection and multiple neovessels. In the peripheral cornea and adjacent to it, there was a clean, rounded depression measuring 6 mm of extension and depth up to the anterior stroma. The presumptive diagnosis was corneal dellen secondary to symptomatic grade II pterygium. The biopsy yielded the presence of squamous cell carcinoma, moderately differentiated, and associated with extensive inflammatory infiltrate with predominance of lymphocytes.

Palabras clave : Corneal dellen; epidermoid carcinoma of the conjunctiva; pterygium.
