Giant destructive basal cell carcinoma of the eyelid

Basal cell carcinoma (bcc) is the most common eyelid neoplasm comprising of about 90% of malignant tumors of eyelids. it is a slowly growing tumor and does not metastasize but can invade orbital and nearby intracranial structures. histological subtypes of periocular bcc are nodular,infiltrative,sclerosing,micronodular,keratotic,basosquamous and superficial. we present a case of periocular bcc in an 83-year-old female which involved both upper and lower lids and medial canthus and had caused ulceration and ectropion of the lower lid with persistent watery eye. histopathological examination of the lesion was consistent with nodular bcc. the patient was advised surgical excision of the tumor but the patient refused and was lost to follow-up.
