[Modified meibography in malignant eyelid tumors of epithelial origin]. / Modifitsirovannaia meibografiia pri zlokachestvennykh novoobrazovaniiakh vek épitelial'nogo proiskhozhdeniia.

INTRODUCTION: Eyelid tumors can be diagnosed using various diagnostic techniques. However, capability of existing methods for determining the type and margins of the tumor at the preoperative stage remains insufficiently studied. PURPOSE: To improve the noncontact infrared meibography technique and determine its diagnostic capabilities for studying structural changes in meibomian glands in malignant eyelid tumors of epithelial origin. MATERIAL AND METHODS: The study included 49 people (66 eyelids), among which 21 (21 eyelids) with malignant eyelid tumors, 11 - with benign eyelid tumors (11 eyelids), and 17 (34 eyelids) comprised the control group. The mean age of patients was 64.8±1.56 years. Meibomian glands of the lower eyelids were photographed in infrared light. Receiver-operating characteristic (ROC) curves were constructed to estimate the sensitivity and specificity of the method. RESULTS: Modified meibography showed 100% sensitivity and 90% specificity in the differential diagnosis of malignant and benign eyelid tumors in 32 patients. Unlike other methods, the modified meibography technique can clarify the margins of tumor growth, which is considered when planning the resection volume. CONCLUSION: Modified meibography can indicate the margins of tumor invasion; it can be successfully used in the differential diagnostics of malignant eyelid tumors of epithelial origin and benign eyelid tumors.

[Refractory form of orbital granulomatosis with polyangiitis: A clinical and morphological study]. / Refrakternaya forma granulematoza s poliangiitom orbity: kliniko-morfologicheskoe nablyudenie.

Orbital granulomatosis with polyangiitis (Wegener's granulomatosis, GPA), which is characterized by granulomatous inflammation with small-vessel vasculitis, can develop in local and generalized forms of the disease. The introduction of current immunosuppressive therapy regimens has improved the prognosis of the disease; however, there are immunosuppressive treatment-refractory forms of GPA, the morphology of which has been inadequately investigated. The paper describes a clinical case of refractory GPA involving the orbit, as evidenced by histological and immunohistochemical examinations. The specific feature of the case is the development of severe fibrosis with the accumulation of mainly type III collagen and the persistence of granulomatous inflammation and productive-destructive vasculitis.

[Eyelid reconstruction after full-thickness resections in benign and malignant tumors].

Full-thickness eyelid defect closure requires appropriate reconstruction, function recovery and acceptable cosmetic result. The aim of the study was to study the results of eyelid reconstruction after full-thickness resections in different benign and malignant tumors. 241 patients (63,5% females, 36,5% males) who underwent full-thickness resectioh of the lower or the upper eyelid due to tumor with primary defect closure were enrolled in the study. Eyelid resection was performed within visually clear tissue 2 mm away of the tumor border in benign and at least 3 mm in malignant lesions. Presented results of different techniques of eyelid reconstruction after full-thickness resections show good functional and cosmetic rehabilitation of patients and low complication rate.
