Abstract
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
