PURPOSE: Natural killer T-cell lymphoma (NKTL) is a highly malignant tumor that typically arises in the nose and/or paranasal sinuses. Isolated orbital involvement by NKTL is extremely rare, and only few case reports exist in the literature. Herein, we report a case of primary orbital NKTL in a young patient who showed very good response to chemotherapy with the SMILE regimen. METHODS: A 28-year-old healthy female presented to us with epiphora and fullness of the lower eyelid...

OBJECTIVE: One of the hypotheses on the pathogenesis of autoimmune diseases, including Graves' disease (GD) and Graves' orbitopathy (GO), involves bacterial or viral infections. Recently, Epstein-Barr virus (EBV) has been proposed to play a role in the pathogenesis of idiopathic orbital inflammatory pseudotumor (IOIP) in Asians. The aim of the present study was to investigate the possible association of GO with EBV infection/exposure, as compared with IOIP, using serum and tissue samples, as well as primary cultures of orbital fibroblasts...

Carotid ophthalmic aneurysms constitute 0.9-6.5% of the aneurysms of the ICA with up to 20% of the cases presenting with visual symptoms. We report a case of an adult woman, presented with chronic headaches and protracted visual alterations progressing to left eye amaurosis. Neuroradiological exams, revealed a giant partially thrombosed carotid ophthalmic aneurysm extending anteriorly, causing pseudotumoral spheno-orbital bone erosion. The patient underwent surgical clipping, evacuation of the thrombotic mass and decompression of the optic pathways with rapid recovery of the vision...

Orbital inflammatory pseudotumor is a rare complication of systemic lupus erythematosus. It may present a challenge for differential diagnosis, especially in the context of treatment with hydroxychloroquine, although dosage and duration of the treatment may guide us. Although high antibody titers can be found, this is not specific.

Orbital biopsy of nonspecific orbital inflammation, commonly referred to as "orbital pseudotumor," typically shows a combination of polyclonal lymphocytes, plasmocytes, leukocytes, macrophages, and variable degrees of collagen deposition. Herein, we report a patient with a positive history of mucocutaneous leishmaniasis who presented with an orbital mass with a histological profile of idiopathic orbital inflammation. Immunohistochemical and molecular analysis of the orbital specimens demonstrated that the orbital inflammation was associated with the presence of antigens of Leishmania braziliensis and DNA from the parasite...

BACKGROUND: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare, highly malignant, extranodal lymphoma that preferentially infiltrates into subcutaneous adipose tissue. No case of SPTCL with the earliest symptoms occurring in the eye region has been reported. We report a case of SPTCL complicated by eyelid swelling. CASE PRESENTATION: A 19-year-old Japanese man presented with worsening left eyelid swelling. The patient's best-corrected visual acuity (BCVA) was 0...

The inflammatory pseudotumour (IPT) is a non-neoplastic entity of unknown origin, and is characterised by a proliferation of connective tissue and a polyclonal inflammatory infiltrate. Central nervous system involvement is uncommon, and usually represents a diagnostic and therapeutic challenge even for the experienced clinician. This reports deals with the case of a 56year-old woman diagnosed with a giant, infiltrating mass centred in the left cavernous sinus, who had a rapid clinical and radiological response to steroid therapy...

Hepatitis C is frequently accompanied by immune-related extrahepatic manifestations affecting the skin, kidneys, central and peripheral nervous system and exocrine glands. We present the case of a 40-year-old man with left-sided ptosis, exophthalmos and headache. MRI demonstrated left-sided orbital pseudotumor with lacrimal and retro-orbital contrast enhancement extending to the cavernous sinus and the vestibulocochlear nerve. Immunological tests of serum and cerebrospinal fluid identified hepatitis C virus (HCV) as a potential causative agent but did not indicate any additional infectious, malignant or immunological disorder...

Inflammatory pseudotumor is a solid fibro-inflammatory tumor that clinically mimics a neoplastic lesion. Inflammatory pseudotumor is usually found in the orbits and lungs, but rarely in the sinonasal area. Presence of pseudotumor in nasal cavity is even scarce and there are only a few reports to date. We present a case of pseudotumor involving the nasal tip area in an adult female mimicking as a slowly enlarging mass.

Thanks to detailed studies conducted in recent years, a new disease syndrome was identified in 2001. It is known as a IgG4-related disease and its differentiation is based on the analysis of IgG4 levels in the affected tissues. The IgG4-related disease is considered to be a generalized pathological process involving a wide spectrum of various disorders that may affect distant organs. Orbital IgG4-related disease is a recently reported issue that may prove important for the elucidation of the etiology of idiopathic, lymphoplasmacytic or fibrotic disorders of various organs, including the orbits...

Idiopathic orbital inflammation or orbital pseudotumor is rare in the pediatric population and may present with ocular findings not normally seen in the adult population. The authors report the case of a 14-year-old boy with idiopathic orbital inflammation who presented with bilateral panuveitis to highlight the features that make this diagnosis more difficult in the pediatric population.

AIM: To explore the role of IgG4 serology in identifying common orbital lymphoproliferative disorders. METHODS: Eighty-one patients with orbital lymphoproliferative diseases were treated in the Department of Ocular Oncology, Beijing Tongren Hospital, Capital Medical University between September 2010 and December 2012. Serum IgG4 levels were measured in 46 cases of idiopathic orbital inflammatory pseudotumor (IOIP), 17 benign lymphoepithelial lesion (BLEL), 12 cases of orbital mucosa-associated lymphoid tissue (MALT), and 6 cases of diffuse large B-cell lymphoma (DLBL) using immuno-scatter turbidmetry (ISTM)...

IgG4-related disease (IgG4-RD) is a newly recognized disease entity. IgG4-RD is characterized by a single or multiple masses in one or more organs; a lymphoplasmacytic infiltrate with a high percentage of plasma cells within the lesion staining for IgG4; a peculiar pattern of fibrosis known as "storiform" fibrosis; and elevated serum IgG4 concentrations. IgG4-RD can occur in various organs, including pancreas, kidneys, lungs, retroperitoneum, and prostate gland. The head and neck involvements of IgG4-RD have been chiefly described in Mikulicz disease (MD), Küttner's tumor, orbital? inflammatory pseudotumor, and idiopathic hypertrophic pachymeningitis (IHP) previously...

INTRODUCTION: Inflammatory myofibroblastic pseudotumors are initially described in the lung and various extrapulmonary sites such as the orbits, palatine tonsils, ears, gingiva, pterygomaxillary space, and periodontal tissues. These tumors rarely involve the larynx and predilection to the glottis occurs in an indolent manner. CASE REPORT: This case describes a laryngeal myofibroblastic tumor in a 46-year-old woman who presented with an aggressive tumor that extended to the floor of the mouth and the base of the tongue...
