Pitfalls in diagnosing orbital malignancy through orbital incisional biopsy: A report of two cases with different scenarios.

Several methods have been implemented to obtain suitable samples from patients for the purpose of histopathological examination and definitive diagnosis. This has been of paramount importance in dealing with oncology cases including orbital neoplasms. Open surgical biopsy has been the common standard technique used in our eye centers in Saudi Arabia for diagnosing various orbital lesions. Other modalities such as fine-needle aspiration biopsy, core biopsy, and imaging-guided core biopsy are not popular. We report two cases where open surgical biopsies may have not been optimal in reaching the desired tissue diagnosis of orbital malignancy on time, thus resulting in delaying further management of the two patients.
