Lacrimal gland CDS-positive, primary, extra-nodal marginal zone lymphoma of mucosa associated lymphoid tissue [MALT] -Type

Mucosa-associated lymphoid tissue [MALT] lymphoma of the ocular adnexae is rare. A 39-year-old woman presenting with proptosis was diagnosed to have non-Hodgkin's lymphoma with intermediate-sized cells and lymphoepithelial lesion. Unlike most MALT lymphomas, this lymphoma was found to be CD5-positive. Small lymphocytic lymphoma/chronic lymphocytic leukemia and lymphoplasmacytic lymphoma are two other entities that are CDS-positive and have a morphological pattern similar to MALT lymphoma. The case report and approach to the diagnosis is discussed

Occult oncocytoma of the lacrimal sac

Oncocytoma of the lacrimal sac is a rarely encountered clinical entity. We report the case of a 72-year-old female patient who was diagnosed to have bilateral nasolacrimal duct obstruction during a pre-cataract surgery screening. Subsequently, she underwent bilateral dacryocystectomy. Histopathological examination of the left lacrimal sac revealed a tumour composed of acini lined by oncocytic cells; features consistent with those of a lacrimal sac oncocytoma. Although rare, oncocytomas arising from the lacrimal sac may co-exist with a nasolacrimal duct obstruction. This report describes the histological and immunochemistry characteristics of oncocytomas and underscores the need to subject all excised lacrimal sacs to histopathological examination

External dacryocystorhinostomy: tips and tricks

Dacryocystorhinostomy or DCR is one of the most common oculoplastics surgery performed. It is a bypass procedure that creates an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium. It may be performed through an external skin incision or intranasally with or without endoscopic visualization. This article will discuss the indications, goals, and simple techniques for a successful outcome of an external DCR

Orbital retinoblastoma: present status and future challenges-a review

Orbital retinoblastoma is a catastrophic event traditionally carrying a dismal prognosis. Although its incidence is less in the developed countries it continues to be one of the major diagnosis at presentation in the developing world. Orbital retinoblastoma encompasses a wide range of distinct clinical entities with varying tumor load. There are no standard treatment protocols as of now but the current preferred management is multimodal with a combination of initial high-dose chemotherapy, surgery, external beam radiotherapy and prolonged chemotherapy for twelve cycles. In spite of progress on all fronts including surgical, medical, diagnostic, genetic and rehabilitative with improving survival rates, however, lack of access to medical facilities, lack of education about the need for early medical attention and cultural resistance to enucleation continue to contribute to an epidemic of extra ocular disease at diagnosis in the developing world. This review introduces the various terminologies used in the spectrum of orbital retinoblastoma, discusses in details the clinical aspects and management protocols, current status and the future directions

Orbital solitary fibrous tumor: a clinicopathologic correlation and review of literature

Orbital solitary fibrous tumor [SFT] is a rare tumor originating from the mesenchyme. Initially described in the pleura and subsequently in other mesenchymal structures, orbit continues to be one of the uncommon extrapleural sites. The diagnosis of orbital SFT cannot be made with certainty on clinical or radiological evaluation and requires histologic studies with immunohistochemical confirmation for which CD 34 is the most specific diagnostic test. We describe clinical presentations, radiological and operative findings, and pathological features of a patient with orbital SFT along with a review of literature
