Abstract : OSSN or malignant tumefactions are neoplastic proliferation of dysplastic squamous epithelium that is non-invasive and earlier known by names such as conjunctival squamous dysplasia, intraepithelial epithelioma, dyskeratosis and Bowens disease.(1) Its incidence ranges from 0.02 to 3.5 per 100000 populations and varies geographically, with greater frequency near the equator.(2) OSSN generally is a slow growing tumour that rarely metastasises, but is capable of causing extensive local tissue destruction.Diffuse type of OSSN which is least common (3) and its presence in a female in the absence of inciting factors is rare. The following case report describes the clinical presentation and histopathological diagnosis of a female patient with diffuse unilateral OSSN.
