A 40-year-old woman presented with vague headaches and blurred vision. Contrast-enhanced magnetic resonance imaging of the brain revealed bilaterally symmetrical diffuse enlargement of the lacrimal glands. A fine needle biopsy of the lacrimal gland was consistent with sarcoidosis. Although, isolated lacrimal gland involvement is rare, it may be the initial clinical presentation of sarcoidosis, ...

BACKGROUND Pyogenic lacrimal gland abscesses are uncommon and thus may not be immediately clinically recognized without a high index of suspicion. FINDINGS We present two patients with preseptal cellulitis and characteristic low-attenuation fluid collections in the lacrimal glands demonstrated on computed tomography (CT). CONCLUSIONS Lacrimal gland abscesses should be considered when dacryo...

= Abstract = Review of 8 cases of heterotopic lacrimal gland tissue in epibulbar conjunctival region disclosed frequent mixture of pilosebaceous structure, adipose tissue, smooth muscle. etc. The term complex choristoma appears appropriate to designate a mixture of this variety, although each element can be predominant in a single lesion. Complex choristoma containing lacrimal gland was commonl...

Maréchal, Hervé, Hélene Jammes, Bernard Rossignol, and Philippe Mauduit. EGF precursor mRNA and membrane-associated EGF precursor protein in rat exorbital lacrimal gland. Am. J. Physiol. 276 (Cell Physiol. 45): C734– C746, 1999.—This study was designed to demonstrate the presence of epidermal growth factor (EGF) in the rat exorbital lacrimal gland. EGF precursor gene transcription was demonstra...

Introduction: When dealing with maxillary sinus pathology, some areas of the sinus remain difficult to examine. In this regard, the pre-lacrimal approach is a minimally invasive technique to reach anterolateral areas of the maxillary sinus while preserving the physiological nasal function.   Materials and Methods: The present study aimed to provide technical hints relate...

Orbital involvement in systemic sarcoidosis is a rare condition. We report a case of orbital sarcoidosis with bilaterally huge lacrimal gland involvement as the initial manifestation of systemic sarcoidosis. A 20-year-old woman admitted the ophthalmology department with progressive bilateral upper eyelid swelling for 6 months. The only pathologic finding was the presence of bilateral, symmetric...

Mucosa-associated lymphoid tissue (MALT) lymphoma is the third most common non-Hodgkin lymphoma, and it is strongly associated with helicobacter pylori infection of the stomach. MALT lymphoma of the lacrimal gland usually presents as a localized disease process in extranodal tissues. The treatment options of MALT lymphoma of the lacrimal gland chiefly include radiation of the tumor, chemotherap...

Here we describe a rare case of a benign tumor in the lacrimal gland of a healthy 4-year-old girl. Mild proptosis was the only abnormality observed on clinical examination. Magnetic resonance imaging of the right orbit revealed an oval, solid, well-circumscribed, homogeneous mass extending from the lacrimal gland and measuring 2.5 × 2.3 × 1.7 cm without any evidence of invasion into adjacent bo...

PURPOSE To determine which of the neurotrophins (NTs)-nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT3), and neurotrophin-4/5 (NT4)-and their receptors (NTrs), TrkA, TrkB, TrkC, and p75, are present in the adult rat lacrimal gland. METHODS RT-PCR was performed on RNA isolated from male rat lacrimal gland, using oligonucleotides specific to each NT and N...

PURPOSE Tears are known to have antimicrobial properties. The authors investigated the presence of the antibacterial enzyme phospholipase A2 (PLA2) in tears and lacrimal glands. METHODS The catalytic activity of PLA2 and the amount of pancreatic group 1 PLA2 and nonpancreatic group 2 PLA2 were measured in homogenates of eight human lacrimal glands from autopsied subjects and in tears from fou...
