Current experience in intraocular fine needle aspiration biopsy in Mexican-Mestizo population

چکیده
Background: Since the first intraocular biopsy performed in 1868 [1] by Hirshberg and experience published by Jackobiec in 1979, fine-needle aspiration biopsy (FNAB) in the eye has been used for several intraocular tumors [2]. In developed countries there is wide experience regarding intraocular FNAB, in contrast to developing countries where this diagnostic tool has been left aside. Aim/Objective: To inform the first number of cases of intraocular FNAB perfomed in Mexican-Mestizo patients of the retina service at the General Hospital “Eduardo Liceaga” in Mexico City. Material and methods: FNAB were perfomed using general anesthesia. Conjuctival incision at 4 mm from limbus followed by the insertion of a 23 gauge needle attached to a syringe using a connector tubbing. Aspiration of 0.10 cc of undiluted vitreous was realized. After wound closure cryotherapy was applied. Vitreous smears were performed and remaining material processed in a cell block. Preparations were stained with Hematoxylin-Eosine and Peryodic Acid Shiff and evaluated under conventional light microscopy. Results: There were a total of 7 cases. The histopathological diagnosis were 2 cases of Coats ́ disease, an intraocular invasive squamous cell carcinoma from the conjunctiva, ciliary body melanocytoma (magnocelullar nevus), acute endophtalmitis, non Hodgkin’s lymphoma and amelanotic melanoma. Complications were one retinal detachment and a vitreous hemorrhage. Conclusions: In difficult cases after the exhaustive clinical evaluation, FNAB becomes a very good choice as a diagnostic tool. In order to minimize serious potential eye complications we strongly advice intraocular FNAB to be performed by trained subspecialists and the microscopic evaluation should be interpreted by an expert ophthalmic pathologist. Althought in our country there is limited experience, first results are encouraging.

متن کاملAssessment of the effectiveness of local anesthesia before thyroid fine needle biopsy considering the size of the nodule
Background: Fine needle aspiration biopsy (FNAB) is usually used to distinguish the malignant and benign nodules. Applying a biopsy needle evokes a sense of fear and pain in the patients. Although some studies refute the usefulness of local anesthesia (LA) prior to fine needle aspiration biopsy, it is still debatable. This prospective cross-sectional study intended to evaluate the effect of LA ...
