Objective: This study correlated the patterns of ocular B- and A-scans of intraocular retinoblastoma (RB) with corresponding histopathology sections. It aimed to establish a more objective basis for determining intraocular retinoblastoma by ultrasonography (UTZ) and to determine the degree of malignancy and viability of the tumor cells.
Methods: New cases of retinoblastoma seen at the University of the Philippines-Philippine General Hospital (UP-PGH) from January 1994 to December 2003 were reviewed. Included were patients who underwent enucleation and whose eyeballs were processed at the UP Institute of Ophthalmology. Those with good quality ocular ultrasonographs (UTZ) and clear matching histopathologic sections were finally selected. Findings were correlated and analyzed.Results: Retinoblastoma (RB) showed multiplicity of lesions on UTZ corresponding to multiple lesions on histopathology. The following characteristic patterns were seen:
Very malignant RB or pseudorosettes: fine, grainy densities on B-scan with short to medium broad spikes on A-scan ("V-W" pattern).
Moderate differentiation with moderate necrosis and early calcific plaques: fine, dense grainy opacities on B-scan with multiple thin, high spikes admixed with tall, broad spikes of calcium deposits on A-scan.
Well-differentiated RB with compact viable cells and no necrosis: large, white densities on B-scan with an initial high spike and high internal reflectivity, sometimes "plateauing," on A-scan with no calcific deposits.
Complete tumor necrosis with calcific plaques: echolucent space with dense, white, plaque-like opacities on B-scan; flat or low spikes mixed with tall, broad spikes corresponding to calcium plaques on A-scan.
Normal vitreous, serous subretinal fluid, or recent hemorrhage: echolucent area on B-scan with flat or low spikes on A-scan.
Conclusion: The three most frequent findings in intraocular retinoblastoma were calcific plaques with liquefaction necrosis, multiplicity of lesions, and pseudorosettes. Ocular ultrasound of retinoblastoma showed good histopathologic correlation.

OBJECTIVETo study the pathological features of uveal melanoma and to evaluate their influence on patients' prognosis.
METHODSParaffin embedded uveal melanoma tissues of 115 cases were examined using routine pathologic methods. Three histological types were classified according to the modified Callender system and patients were followed clinically. The data were done regression and survival analysis by SPSS statistic soft.
RESULTSThe patient with epithelial cell type, mixed type, and spindle cell type uveal melanoma have different life times, the average life time is 35.6 +/- 21.5 months, 63.7 +/- 37.0 months, 69.5 +/- 36.5 months in turn, patients with epithelial uveal melanoma had shorter survival time than other two types. The survival time was negatively related to the largest diameter of contact area with the sclera, the largest height and the depth of tumor invasion to the sclera.
CONCLUSIONSEpithelial uveal melanoma is more malignant than the other two types. Histological classification of this tumor combined with other pathologic features can indicate the patient's prognosis.

4.Adenoma of nonpigmented epithelium in ciliary body: literature review and case report.
Journal of Zhejiang University. Science. B 2007;8(9):612-615
Adenomas of the nonpigmented ciliary epithelium (NPCE) are often clinically indistinguishable from amelanotic malignant melanomas of the ciliary body or metastatic carcinomas. This paper reports a case study of a distinctive variant of adenoma of the NPCE, which clinically appears as epiretinal membrane in the macular region. Histopathologic studies have revealed this is an adenoma of the NPCE. Identification of this clinic feature is important because it will miss the diagnosis of the adenoma of the NPCE. In this case study, B-scan ultrasonography as well as computerized tomography (CT) has been used to provide help in diagnosing the ciliary body tumor. Because of their anterior location in the ciliary body, partial lamellar sclerouvectomy is an effective method of treatment.

Lymphomas in the eye tend to be localized and to have a better prognosis. We reviewed the clinical presentation, treatment outcome and complications of primary lymphomas of the eye at a single institute focusing on the clinical significance of adequate staging and the prognostic value of pathological subtypes. Twenty-four patients with lymphoproliferative lesion of the eye were treated and followed up. The orbit was the most commonly involved site. Twenty-one patients had unilateral diseases and three patients had bilateral. Histological findings revealed 22 malignant lymphomas, one inflammatory pseudotumor and one atypical lymphoid hyperplasia. Using the NCI Working Formulation, most of the malignant lymphomas were primarily low grade: diffuse small lymphocytic, 15; diffuse small cleaved three; diffuse large cell, three; and diffuse mixed, one. The stages of lymphoma were IAE in 21 patients, IBE in one patient, and IIAE in two patients. Twenty-five of the 27 treated eyes remained disease-free during the median follow-up period of 16 months. Nineteen patients received radiotherapy, five patients received chemo-radiotherapy and one patient received only surgical excision. Two patients relapsed outside the treated field. None of the patients complained of severe dry eye syndrome or cataract formation. In conclusion, after complete staging work-up, locally-confined low grade orbital lymphomas can be up to 90% controlled with radiotherapy alone. By contrast, combined treatment is advised in patients with intermediate and high grade lesions.

6.Subretinal Inflammatory Myofibroblastic Tumor: Clinicopathological Findings.
Korean Journal of Ophthalmology 2005;19(3):235-238
PURPOSE: To present a case of inflammatory myofibroblastic tumor which was manifested as an idiopathic subretinal mass without underlying pathology. METHODS: The subretinal mass was surgically excised and evaluated histopathologically. Fluorescein angiography and optical coherence tomography were performed pre- and post-operatively. RESULTS: The mass was histologically composed of lymphoplasma cell infiltration and fibrous proliferation without microorganisms or malignant cells. Immunohistochemistry for smooth muscle actin revealed myofibroblasts as a major cellular component. Preoperative optical coherent tomography showed that the lesion was contiguous to the retina while inducing foveal detachment. Postoperatively, the fovea was attached with visual recovery, and the subretinal lesion did not recur during the follow up. CONCLUSIONS: Inflammatory myofibroblastic tumors may be included in the differential diagnoses of subretinal masses.

7.Dilemma in management of ocular medulloepithelioma in a child.
Chinese Medical Journal 2012;125(2):392-395
Medulloepithelioma, a rare tumor, arises from the epithelium of the medullary tube. In this article, we present a 3-year-old boy who suffered from secondary glaucoma, initially presumed the primary disease was endophthalmitis. Subconjunctival mass was later found, pathologically proved to be medulloepithelioma. We discuss the patient management with emphasis on the early signs of examination and the role of ultrabiomicroscopy (UBM) in evaluating pediatric secondary glaucoma and in influencing the management of patients with medulloepithelioma.

OBJECTIVE:
To analyze the correlation of methylation status of dachshund homolog 1 (DACH1) gene in tumor tissues with clinicopathological characteristics and prognosis of patients of esophageal cancer.
METHODS:
Tumor tissue, paracancerous tissue and normal esophageal mucosal specimens of 104 patients with esophageal cancer were collected. Methylation-specific PCR was used to determine the methylation status of the DACH1 gene. Univariate analysis and multivariate Logistic regression model were used to analyze the correlation between DACH1 methylation status and clinical pathological characteristics of the patients. Kaplan-Meier survival curve was used to analyze the relationship between DACH1 methylation status and prognostic survival of patients.
RESULTS:
The methylation rate of the DACH1 gene in esophageal cancer tumor tissue was 30.77% (32/104), which was higher than those in adjacent tissues (1.92%) and normal esophageal mucosa (0%) (P< 0.05). The methylation status of the DACH1gene in tumor tissues of patients did not correlate with the patient's age, gender, and pathological type (P> 0.05) but tumor differentiation, TNM staging, and lymph node metastasis(P< 0.05). The degree of tumor differentiation, TNM stage, and lymph node metastasis of patients are independent risk factors for the methylation status of the DACH1 gene. By March 2020, 89 of the 104 patients had died. Among them, the median survival foresophageal cancer patients with DACH1 gene methylation was 22 months, which was lower than 34 months of those without DACH1 methylation (P< 0.05).
CONCLUSION
Methylation of the DACH1 gene may be involved in the occurrence and progress of esophageal cancer. The degree of tumor differentiation, TNM stage, and lymph node metastasis of patients are independent risk factors for the methylation status of the DACH1 gene. Patients with esophageal cancer but unmethylated DACH1 gene have a longer prognostic survival.

A 53-year-old woman complaining of vertical diplopia, presented with a localized swelling in the right lower lid. Magnetic resonance imaging studies demonstrated a relatively well-defined mass in the inferior rectus with similar signal characteristics to the muscle. Excisional biopsy of the mass revealed granular cell tumor composed of S-100 positive cells with acidophilic granular cytoplasm and a peripheral lymphocytic infiltration. Granular cell tumor, which is very rare in the orbit, should be considered in the differential diagnosis of tumors adjacent to or within the extraocular muscles, particularly in the inferior orbit.

Herein, we report a case of nasal natural killer T-cell lymphoma (NKTL) with intraocular involvement. A 57-year-old woman was referred due to a three-day history of photophobia and diplopia in the left eye. One-month previously, she was diagnosed with nasal NKTL of the right nasal cavity. Ophthalmic examination revealed conjunctival injection and ptosis. The left pupil was fully dilated and non-reactive to light. Ocular motion was restricted on left-upper gaze. Five days later, anterior uveitis developed and persisted despite topical steroid treatment. An orbital magnetic resonance imaging was without specific findings, however, ophthalmoplegia, vitreous opacity, and an iris mass were observed. A diagnostic anterior chamber aspiration was performed. Aqueous humor aspiration revealed 35% morphologically atypical lymphocytes. After an intravitreal triamcinolone injection, radiotherapy and chemotherapy were administered; this resolved the uveitis and iris mass. When refractory uveitis or orbital pseudotumor occurs in patients with nasal NKTL, ocular and orbital involvement of the NKTL should be considered.
