The aim of the present study was to evaluate the scope and the limitations of fine needle aspiration cytology (FNAC) in orbital and ocular adnexal lesions. This study was a retrospective audit of 389 cases of orbital and ocular adnexal lesions subjected to FNAC over a period of 12 years (1998-2009). The cyto-smears were reviewed and the lesions were categorized under different diagnostic categories in adult and pediatric population. Three hundred and one adult patients (age ≥15 years) and 88 pediatric patients (age ≤14 years) constituted the study group. In the adult population, there were 23.3% cases of infectious and lymphoproliferative lesions and 12.6% of benign cysts. In the pediatric population, 18.2% cases had infectious and lymphoproliferative lesions and 8% had benign cysts. Various benign tumors (9.6% in adults) included pleomorphic adenoma, meningioma, and schwannoma. Benign vascular tumors predominated in the pediatric population. A majority of malignant tumors in adults were lymphoreticular malignancies (12.6%); non-Hodgkin's lymphoma being the most common followed by malignant epithelial tumors (10.3%). Nearly 3.6% cases of soft tissue/bone sarcomas and 6.3% of metastatic tumors were seen in adult population. However, most of the orbital tumors in the pediatric population were malignant small blue round cell tumors (33%). FNAC is a cost-effective technique with good diagnostic value in the assessment of ophthalmic lesions, especially when sampling and interpretation are performed by experienced personnel in the light of clinico-radiological information.

    ABSTRACT: OBJECTIVE: To evaluate the diagnostic yield of ultrasound-guided core-needle biopsy of extra-ocular orbital lesions. METHODS: Fifty-five patients with monolateral exophthalmos prospectively underwent computed tomography (CT) to investigate the presence of an extra-ocular mass (n = 25). Excluding benign lesions (n = 7) and patients in whom CT revealed an unknown primitive malignancy (n = 5), 13 patients (7 male, 6 female; mean age 62 ± 16 years) underwent ultrasound. Lesion appearance (echotexture, power Doppler vascularisation), size, position with respect to the cone and to the globe were recorded. Ultrasound-guided biopsies were performed (automatic, n = 9; semi-automatic 18-G needle, n = 4). Sample adequacy and complication rate were recorded. RESULTS: Ultrasound demonstrated hypoechoic lesions with mild power Doppler vascularity, that were completely (n = 7) or partially extra-conal (n = 6), located laterally (n = 8) or posteriorly (n = 5) to the globe. Mean size was 3.25 cm. All biopsies yielded adequate material for histological and immunohistochemical analysis (nine non-Hodgkin's lymphomas, two adenocarcinomas, one lymphoid hyperplasia, one inflammatory pseudotumour). Complications included cutaneous eyelid haematoma (n = 3) and retro-bulbar haematoma (n = 1), treated conservatively and resolved at 10-day follow-up. No immediate or delayed vision reduction was reported. CONCLUSIONS: Ultrasound-guided core-needle biopsy of extra-ocular orbital lesions is feasible and accurate, being free from long-term complications. This procedure provided 100 % adequate samples to achieve final diagnosis. KEY POINTS : • Ultrasound-guided core-needle biopsy of extra-ocular orbital lesions seems feasible and accurate. • In this series it provided a final diagnosis in 13/13 cases. • It appears free from long-term complications. • It provides immunohistochemical analysis of the specimen. • It should represent a valuable alternative to surgical biopsy.

    ABSTRACT: Fine-needle aspiration cytology (FNAC) of orbital lesions is now increasingly popular. Because of its unique location and the occurrence of varieties of lesions, diagnosis of orbital lesion is a challenge to the cytopathologists. FNAC of orbital and eyelid tumors is a suitable diagnostic technique that necessitates close co-operation between the ophthalmologist and pathologist. No radical procedure should be planned on the basis of FNAC, but it allows the diagnosis of a new primary lesion or the recurrence or metastasis of a tumor and can be done to identify lesions that require either specific medical therapy, as in nonresectable, inflammatory, and lymphoid tumors, or limited surgery for benign resectable neoplasms. With the help of various ancillary techniques a definitive diagnosis is possible on orbital and adnexal lesions. It is essential to have a detailed knowledge on the FNAC of these lesions and their potential pitfalls. In this present review, we have discussed various orbital lesions, their clinical presentations, cytomorphology, and ancillary techniques to confirm the diagnosis. Diagn.
