Purpose Among peripheral nerve sheet tumors, an orbital hybrid neurofibroma‐schwannoma has been described twice. We describe a third case of orbital tumor with features of both a neurofibroma and a schwannoma. Methods Case report. A 39 year old man presents with diplopia and decreased vision (0.6) in the left eye. He has a proptosis of 7 mm, with mechanical restriction of elevation and horizontal eye movements. MRI shows a well‐defined lesion (2,5 x 1,9 x 2,3 cm) in the superotemporal intraconal space, displacing the globe, optic nerve and superior and lateral rectus muscles. The tumor demonstrates heterogeneous contrast enhancement, and is diagnosed as a probable cavernous hemangioma. Through a transconjunctival approach a red‐blueish lesion was found with a thin capsule and without lateral adhesions. The tumor could be extracted in 2 parts and consisted of a yellow/white coherent soft mass. Results Patient had complete recovery of visual acuity, and only diplopia in extreme lateral gaze. The pathology revealed a tumor composed of small spindle cells arranged in fascicles. The cells showed no atypia and there was no mitotic activity. There were also less cellular areas with a myxoid component. At places we could recognize a fibrous capsule surrounding the tumor. The tumor cells were strongly and diffuse positive with S100. In a few enclosed axons there was focal reactivity with neurofilament. The image is that of a neural tumor with features of both a neurofibroma and a Schwannoma. Conclusions This is the third reported orbital hybrid neurofibroma‐schwannoma. Although this type of tumor elsewhere in the body is often associated with schwannomatosis and neurofibromatosis, our patient did not show signs of systemic involvement.
Purpose. To analyze and describe corneal and conjunctival tumor thickness and internal characteristics and extension in depth and size and shape measured by two noninvasive techniques, anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM). Design. Systematic review. Methods. This systematic review is based on a comprehensive search of 4 databases (Medline, Embase, Web of Science, and Cochrane Library). Articles published between January 1, 1999, and December 31, 2015, were included. We searched for articles using the following search terms in various combinations: “optical coherence tomography”, “ultrasound biomicroscopy”, “corneal neoplasm”, “conjunctival neoplasm”, “eye”, “tumor” and “anterior segment tumors”. Inclusion criteria were as follows: UBM and/or AS-OCT was used; the study included corneal or conjunctival tumors; and the article was published in English, French, Dutch, or German. Results. There were 14 sources selected. Discussion. Several studies on the quality of AS-OCT and UBM show that these imaging techniques provide useful information about the internal features, extension, size, and shape of tumors. Yet there is no enough evidence on the advantages and disadvantages of UBM and AS-OCT in certain tumor types. Conclusion. More comparative studies are needed to investigate which imaging technique is most suitable for a certain tumor type.
This erosive sino-orbital inflammatory myofibroblastic tumor is a novel finding mimicking a malignant tumor.
We present a case of a woman with a swollen upper eyelid in ptosis, conjunctival nodules, and chemosis present for a couple of weeks. She did not respond to therapy for hordeolum or allergy. A biopsy followed by histopathological examination showed a large infiltration of eosinophilic granulocytes and flame figures, so the diagnosis of Wells syndrome was made. Oral methylprednisolone in high dose was necessary, and tapering was slow because of frequent bouts of relapse. After 3 months, the swelling and hard feeling of the eyelid disappeared, but a slight ptosis remained. Eyelid swelling and eosinophilia recurred 18 months after resolution of the first episode.
Cataract is a common condition observed in patients with diabetes mellitus frequently requiring surgical intervention. The bag-in-the-lens (BIL) intraocular implant is an alternative approach to standard lens-in-the-bag cataract surgery. The lens is supported by anterior and posterior capsulorhexes, which confers a number of advantages in terms of lens centration, rotational stability and prevention of posterior capsular opacity. The purpose of this report is to describe the results of BIL cataract surgery in a retrospective cohort of diabetic patients. Fifty-four cases of BIL surgery are included with a follow-up period of 1 year. Visual acuity outcomes were comparable to previously published standard lens-in-the-bag procedures. There were no reports of posterior capsular opacification and the grade of diabetic retinopathy remained stable. Three cases of clinically significant macular edema were detected over the follow-up period. We conclude that the BIL implantation technique is an advantageous approach to treating cataract in the diabetic population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
