OBJECTIVE

To report a case of lacrimal gland adenoid cystic carcinoma in a 37-year-old female managed with globe-sparing surgery and adjuvant radiotherapy.

This is a case report.

This report details a 37-year-old Filipino female who presented with a 4-month history of right eye pain and non-axial proptosis. Computed tomography (CT) scan showed a right heterogenous extraconal mass with orbital roof remodeling. Lateral orbitotomy with excision biopsy was performed. Final histopathologic diagnosis of adenoid cystic carcinoma of the lacrimal gland was made based on the classic morphology and distinct arrangement of the neoplastic cells. Systemic surveillance revealed absence of metastases. Patient completed adjuvant radiotherapy four months post-operatively. Vision was preserved at 20/20 without signs of tumor recurrence five months post-operatively.

Adenoid cystic carcinoma is an aggressive lacrimal gland malignancy; hence, meticulous examination and high index of suspicion cannot be over-emphasized. Globe-sparing surgery with adjuvant radiotherapy could significantly preserve quality of life.

This study investigated the therapeutic effects of Yiguanjian on dry eye in rats and its mechanisms involving the T helper cell 17(Th17)/regulatory T cell(Treg) balance. The rat model of dry eye was established by administrating 0.2% benzalkonium chloride solution in eye drops. After successful modeling, the rats were treated with Yiguanjian for 4 consecutive weeks. The Schirmer test was carried out to assess the lacrimal gland function, corneal fluorescence staining to detect corneal injury, hematoxylin-eosin staining to observe corneal histopathology, enzyme-linked immunosorbent assay to measure serum levels of interleukin(IL)-6, IL-8, IL-17A, IL-21, and tumor necrosis factor-α(TNF-α), RT-qPCR to analyze mRNA levels of retinoic acid receptor-related orphan receptor gamma t(RORγt) and forkhead box protein p3(Foxp3) in the corneal tissue, immunofluorescence double staining to evaluate RORγt and Foxp3 expression in the lacrimal gland tissue, and Western blot to quantify the protein levels of signal transducer and activator of transcription 3(STAT3), phosphorylated STAT3(p-STAT3), Janus kinase 2(Jak2), phosphorylated Jak2(p-Jak2), RORγt, and Foxp3 in the corneal tissue. The results demonstrated that Yiguanjian increased tear secretion(P<0.01), alleviated corneal damage and pathological changes, and lowered the serum levels of IL-6, IL-8, IL-17A, IL-21, and TNF-α(P<0.05) in model rats. Additionally, Yiguanjian decreased the ratio of RORγt to Foxp3 in the corneal and lacrimal gland tissue(P<0.01), downregulated the protein levels of STAT3, Jak2, and RORγt(P<0.05), upregulated the protein level of Foxp3(P<0.05), and inhibited phosphorylation of STAT3 and Jak2(P<0.01). These findings indicate that Yiguanjian ameliorates ocular surface dysfunction in dry eye rats by restoring Th17/Treg balance in the corneal and lacrimal gland tissue and suppressing systemic inflammatory cytokine release, thus mitigating ocular surface inflammation.

Objective: To describe the clinicopathologic features and outcome of a patient with epithelial-myoepithelial carcinoma of the lacrimal gland who underwent modified lateral orbitotomy with en toto removal of the lesion and adjuvant radiotherapy. Methods: This is a case report. Results: A 31-year-old Filipino male seafarer presented with a 2-month history of an enlarging left superotemporal orbital mass and inferonasal displacement of the globe. Magnetic resonance imaging revealed a superotemporal extraconal mass within the lacrimal sac fossa with evidence of osseous infiltration of the superolateral orbital rim. Modified lateral orbitotomy was performed with en toto removal of the lesion and the clinically infiltrated adjacent lateral bony margin. Histopathologic diagnosis of epithelial-myoepithelial carcinoma of the lacrimal gland was made based on the classic and distinct biphasic morphology and was confirmed with immunohistochemistry studies (cytokeratin-7, S-100, and p63). Systemic surveillance using positron emission tomography and computed tomography scan with contrast revealed no evidence of regional or distant metastasis. Adjuvant radiotherapy of the orbital area was performed for increased local control. Twelve months postoperatively, the patient showed no evidence of tumor recurrence. Conclusion Epithelial-myoepithelial carcinoma of the lacrimal gland is a rare condition, and this is the first documented case from the Philippines. Accurate diagnosis is necessary for appropriate treatment. It should be included in the differential diagnosis of infiltrative lesions in the lacrimal gland fossa.

Objective: To describe the cytopuncture microbiopsy (CM) technique performed during transcanalicular endoscopic lacrimal duct recanalization (TELDR) in patients with primary acquired nasolacrimal duct obstruction (PANDO) as an alternative to open biopsy, the standard method used in collecting specimen. Methods: This is a noncomparative, interventional case series with histopathologic correlation. Patients diagnosed with complete PANDO who underwent TELDR with balloon dacryoplasty and silicone intubation with CM at University of Santo Tomas Hospital from October 2014 to January 2017 were included. Results: Twenty (20) tissue specimens from the lacrimal sac and nasolacrimal duct were obtained from 18 patients. There were 16 females and 2 males included in the study. Mean age was 57.5 years. All specimens revealed few clusters of benign epithelial cells with few degenerated mononuclear cells and lymphocytes, and singly scattered lymphocytes that are set in fibrinous background. Tissue cytology studies were negative for malignant cells. Conclusion CM is a minimally invasive procedure that offers an alternative to open biopsy technique that can be done routinely during TELDR.

Objective:To investigate the effectiveness of nasal endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum in resecting recurrent nasal inverted papilloma. Methods:Patients with recurrent nasal inverted papilloma who underwent reoperation in our hospital during the past 2 years were included . The nasal septum may hinder full access to and effective treatment of the lesions at the anterior and medial wall of the maxillary sinus by endoscope, aspirator and surgical instrument in the narrow aperture of the prelacrimal recess, although these lesions could be observed by 70° nasal endoscope. Results:The nasal septum is temporarily opened on the basis of the prelacrimal recess approach, and the nasal endoscope and instrument was introduced through trans-septal window, so as to provide a better view of the operative field and the angular range of the instrument's movement. Conclusion:The recurrent nasal inverted papilloma could be successfully managed by re-endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum, and no recurrence was observed during the 2-year follow-up. This surgical approach is recommended for the inverted papilla which originates from the anterior medial wall of the maxillary sinus, as the tumor can be removed completely using this surgical approach.

Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disorder that affects mainly salivary and lacrimal glands, but its cause remains largely unknown. Clinical data indicating that SS occurs in a substantial proportion of patients with lupus points to common pathogenic mechanisms underlying the two diseases. To address this idea, we asked whether SS develops in the lupus-prone mouse strain sanroque (SAN). Owing to hyper-activation of follicular helper T (Tfh) cells, female SAN mice developed lupus-like symptoms at approximately 20 wk of age but there were no signs of SS at that time. However, symptoms typical of SS were evident at approximately 40 wk of age, as judged by reduced saliva flow rate, sialadenitis, and IgG deposits in the salivary glands. Increases in serum titers of SS-related autoantibodies and numbers of autoantibody-secreting cells in cervical lymph nodes (LNs) preceded the pathologic manifestations of SS and were accompanied by expansion of Tfh cells and their downstream effector cells. Thus, our results suggest that chronic dysregulation of Tfh cells in salivary gland-draining LNs is sufficient to drive the development of SS in lupus-prone mice.

Aging is a complex process associated with dysregulation of the immune system and low levels of inflammation, often associated with the onset of many pathologies. The lacrimal gland (LG) plays a vital role in the maintenance of ocular physiology and changes related to aging directly affect eye diseases. The dysregulation of the immune system in aging leads to quantitative and qualitative changes in antibodies and cytokines. While there is a gradual decline of the immune system, there is an increase in autoimmunity, with a reciprocal pathway between low levels of inflammation and aging mechanisms. Elderly C57BL/6J mice spontaneously show LGs infiltration that is characterized by Th1 but not Th17 cells. The aging of the LG is related to functional alterations, reduced innervation and decreased secretory activities. Lymphocytic infiltration, destruction, and atrophy of glandular parenchyma, ductal dilatation, and secretion of inflammatory mediators modify the volume and composition of tears. Oxidative stress, the capacity to metabolize and eliminate toxic substances decreased in aging, is also associated with the reduction of LG functionality and the pathogenesis of autoimmune diseases. Although further studies are required for a better understanding of autoimmunity and aging of the LG, we described anatomic and immunology aspects that have been described so far.

PURPOSE: We report an unusual case of a keratinizing cyst on the lacrimal punctum. CASE SUMMARY: A 49-year-old female presented with an outpouching punctal mass at the left lower lid that occurred a week prior to her visit. Histopathological examination revealed a cyst filled with keratin arranged in lamina and surrounding the bacterial colony. The epithelial wall was composed of multilaminar, keratinizing squamous epithelium without goblet cells. The features were consistent with a keratinizing cyst. There was no recurrence at 4 months after the excision, and the punctum was patent. CONCLUSIONS: Keratinizing cyst should be considered as a differential diagnosis of the cystic mass of the punctum. Because it has an excellent prognosis after surgical resection, complete resection should be performed if a keratinizing cyst is suspected.
