We report a rare case of Epstein-Barr virus (EBV)-positive polymorphic B-cell lymphoproliferative disorder (LPD) involving the lacrimal gland of a 28-year-old, apparently immunocompetent woman. She presented with a chief complaint of orbital swelling and tenderness and was found to have a lesion involving the right lacrimal gland and distal superior and lateral rectus muscles. Histology of the lesion revealed histiocytes with pleomorphic nuclei, reactive lymphocytes, and scattered cells that resembled the Reed-Sternberg (R-S) cells of classical Hodgkin lymphoma...

Aim: To report a rare presentation of adenoid cystic carcinoma (ACC) of the lacrimal gland. Method: This is a case report presenting clinical, radiographic, and histopathologic findings. Results: A 72-year-old female with no reported ocular symptoms was found to have an incidental right orbital mass on imaging. Additional studies revealed multiple liver lesions, which were biopsied and found to be consistent with ACC. She was then referred to the ophthalmology service, where ocular examination demonstrated 2...

We prepared magnesium hydroxide (MH) nanoparticles, and investigated their effect when combined with dissolved carteolol on the bioavailability and intraocular pressure (IOP)-reducing effect of carteolol. The carteolol was solved in saline containing additives (0.5% methylcellulose, 0.001% benzalkonium chloride, 0.5% mannitol; CRT-solution). MH nanoparticles were prepared by a bead mill method with additives. Then carteolol/MH microparticle and carteolol/MH nanoparticle fixed combinations (mCMFC and nCMFC) were prepared by mixing the CRT-solution and MH particles...

A 23-year-old woman presented with right-sided painless proptosis that developed in 12 months. MRI studies demonstrated a well-delineated tumorous enlargement of the right lacrimal gland with homogenous signal intensity and compressing the globe. The tumor was removed totally and in 1 piece with the tentative diagnosis of a pleomorphic adenoma. Pathologic examination revealed biphasic neoplastic elements, which were composed of the cartilaginous matrix and small round cell component. Immunohistopathological examination showed positive CD99 staining and negative reaction to S100, panCK, and CD15...

BACKGROUND: Epiphora has a significant impact on the patient's quality of life and is commonly caused by nasolacrimal duct obstruction. Dacryocystorhinostomy (DCR) has traditionally been performed via an external approach, which involves a skin incision. With the advent of endoscopes, the endonasal approach to DCR has gained significant popularity. METHOD: To prospectively compare the quality of life of adult patients who underwent either an endonasal or an external DCR for acquired nasolacrimal duct obstruction, the Lacrimal Symptom Questionnaire (Lac-Q) was administered before and after surgery...

"Sinus headache" is a common chief complaint that often leads patients to an otolaryngologist's office. Because facial pain may or may not be sinogenic in origin, the otolaryngologist should be equipped to evaluate and treat or to appropriately refer these patients. Analysis of current data indicates that the majority of patients who present with sinus headaches actually have migraines. Furthermore, the downstream effect of the cytokine cascade initiated in migraine physiology can cause rhinologic symptoms, including rhinorrhea, congestion, and lacrimation, which may also confound diagnosis...

The Jurassic Yanliao theropods have offered rare glimpses of the early paravian evolution and particularly of bird origins, but, with the exception of the bizarre scansoriopterygids, they have shown similar skeletal and integumentary morphologies. Here we report a distinctive new Yanliao theropod species bearing prominent lacrimal crests, bony ornaments previously known from more basal theropods. It shows longer arm and leg feathers than Anchiornis and tail feathers with asymmetrical vanes forming a tail surface area even larger than that in Archaeopteryx...

Case summary: A 14-year-old female spayed Abyssinian cat, which about 1 year previously underwent thoracic limb amputation, radiotherapy and chemotherapy for an incompletely excised vaccine-related fibrosarcoma, was presented for evaluation of corneal opacity in the left eye (OS). The ocular surface of both eyes (OU) had a lackluster appearance and there was a stromal corneal ulcer OS. Results of corneal aesthesiometry, Schirmer tear test-1 (STT-1) and tear film breakup time revealed corneal hypoesthesia, and quantitative and qualitative tear film deficiency OU...

Purpose: The role of cystic fibrosis transmembrane conductance regulator (CFTR) in lacrimal gland (LG) function has only recently received some attention, mainly from our group. In the present study, we investigated the potential changes of LG pathology, tear secretion, ocular surface integrity, and fluid secretion in isolated LG ducts from CFTR knockout (KO) mice. Methods: Tear production and ocular surface integrity were investigated in anesthetized wild-type (WT) and KO mice using cotton threads and fluorescein staining, respectively...

Primary Sjögren's syndrome (pSS) is a solitary poorly understood autoimmune inflammatory disease by involvement of the salivary and lacrimal glands resulting in dry mouth and dry eyes. Myoepithelial cells (MECs) are cells knowing for its hybrid epithelial and mesenchymal phenotype that are important components of the salivary gland (SGs) structure aiding the expulsion of saliva from acinar lobules. In this study we investigate possible alteration in the myofilament component of MECs in SGs specimens obtained from pSS patients in comparison with healthy subjects, to evaluate MECs hypothetical involvement in the pathogenesis of pSS...

Mikulicz Syndrome (MS) is a rare chronic condition characterized by the abnormal enlargement of glandular tissue in the head and neck. Patients usually present with enlarged lacrimal and parotid glands. While this can be a benign self-limiting condition, other complex systemic diseases, such as sarcoidosis, may represent other underlying etiologies. We present a case of MS in a patient with a history of Crohn's disease.

Sjögren's syndrome (SS) is a systemic chronic autoimmune disorder affecting the lacrimal and salivary glands. SS may manifest as primary SS (pSS) or secondary SS (sSS), the latter occurring in the context of another autoimmune disorder. In both cases, the dry eyes and mouth affect the patient's quality of life. Late complications may include blindness, dental tissue destruction, oral candidiasis and lymphoma. This paper reports two cases of SS, each of them presenting unusual oral nodular lesion diagnosed as relapsed MALT lymphoma and mucocele...

Dacryoadenitis is unusual in children, and noninfectious causes can be manifestations of serious undiagnosed systemic conditions. This report brings further attention to this rarely-encountered condition and emphasizes its association with IgG4-related disease, a group of inflammatory disorders of high current interest whose spectrum of manifestations continues to evolve. The pediatric ophthalmologist could be in the position of identifying a patient's serious and previously unappreciated illness.

Computed tomography (CT) images have been used in very few studies on distances to the ethmoidal arteries in the orbit. Most other studies have included direct measurements on cadavers and frequently quote the 24-12-6 mm rule to describe distances from the anterior lacrimal crest to the anterior and posterior ethmoidal foramina (AEF and PEF), optic canal (OC), respectively. However, the large interindividual variation of distances renders absolute values less applicable in a clinical setting. Preoperative measurements on CT images may provide more precise distances than absolute rules and thus lead to safer orbital surgery...

In the present study, the effects of erlotinib on mouse tear function and corneal epithelial tissue structure were investigated. Throughout the 3 weeks of treatment, no notable differences were observed in the body, eye or lacrimal gland weights of the control and experimental mice. However, in the experimental group, the tear volume and break‑up times of tear film were significantly lower following treatment with erlotinib compared with the control group. Corneal fluorescein staining in the experimental group revealed patchy staining, and the Lissamine green staining and inflammatory index were significantly higher in the experimental group at 3 weeks than in the control group...
