Presenting features for developmental cysts of the orbit.

Purpose: To evaluate the clinical features of developmental cysts of the orbit.

Patients And Methods: Retrospective study of patients who had excision of cysts between 1992 and 2020.

Results: Three hundred and 58 patients (189 male; 53%) with orbital developmental cysts were identified, all being unilateral.

Persistent orbital inflammation following complete excision of deep dermoid cysts.

Piecemeal excision of dermoid cysts carries the risk of implanting epithelial fragments into orbital fat, which is well recognized to continue secreting oily debris, inciting chronic, often granulomatous inflammation. The authors present the clinical and histological details for two patients with persistent lipogranulomatous inflammation for years after piecemeal excision of deep orbital dermoid cysts, in the absence of any residual epithelium. The importance of copious saline lavage - to 'float-out" and reduce microscopic lipid droplets - is also emphasised.

Congenital Conjunctival Cysts of the Orbit.

Purpose: To evaluate the clinical presentation, anatomical location, and histological features of congenital conjunctival cysts of the orbit. The location and the histological features of inflammation in these patients were compared with those for 293 orbital dermoid cysts.

Patients And Methods: Retrospective review of the clinical details, imaging, and histopathology for patients who had excision of conjunctival cysts from their orbit between 1992 and 2020; patients with a history of trauma or surgery were omitted.

[Treatment and management of orbital tumors].

Background: There are various options for the conservative treatment of the most frequent orbital tumors. These can delay, complement or be superior to the surgical approach, which is often prone to complications.

Objective: This article gives a summary of the possible treatment options for the most common orbital tumors in childhood and adulthood.

Dacryops and clinical diagnostic challenges.

Objective: The study aims to describe the clinical and histopathologic features of different types of dacryops and their clinical diagnostic challenges.

Methods: This is a retrospective cohort study of all surgically excised cases of dacryops in 2 tertiary eye hospitals in Riyadh, Saudi Arabia.

Results: The study included 58 dacryops specimens from 55 patients with an average age of 41.

Spheno-Orbital Dermoid Masquerading as Recurrent Orbital Abscess.

A 10-month-old girl presented with eyelid edema and erythema that did not improve with systemic antibiotics. Due to a lack of improvement, MRI was performed to avoid ionizing radiation from CT. An orbital abscess was recognized and drained.

Intraconal orbital dermoid cyst: a rare location.

Intraconal dermoid cysts are very unusual in routine clinical practice. Clinical symptoms depend upon the site and extension of the lesion. Though rare, proptosis, diplopia, and orbital pain are the presenting symptoms encountered in patients with an intraorbital dermoid cyst.

Giant Deep Orbital Dermoid Cyst Presenting in Infancy.

Orbital dermoid cysts are benign choristomas that are very common in children and occur most often as a lateral or medial mass associated with the frontozygomatic or frontoethmoidal suture line. The authors present an unusual case of an occult giant deep orbital dermoid cyst in infancy that initially presented with a small, benign appearance and central upper eyelid location on clinical exam. Orbitotomy with complete excision prevented further ocular sequelae in this 11-month-old.

[Diagnostics of benign and malignant tumors of the orbit].

Background: Orbital space-occupying lesions can have a significant impact on the quality of life. Depending on the dignity and etiology of the mass, they can even represent a life-threatening process, which must be timely treated in an interdisciplinary cooperation.

Objective: To achieve a comprehensive overview about the diagnostics and frequency of malignant and benign masses of the orbit.

Mature Orbital Teratoma.

Orbital teratoma is a rare tumour that is composed of tissues derived from all three germ cell layers. It presents, in otherwise, healthy neonates with unilateral proptosis that progresses rapidly, threatening vision through optic nerve compromise or exposure keratopathy. Globe conservation may be difficult too in advanced cases.

Ocular and Periocular Tumors in India: An EyeSmart Electronic Medical Record Analysis of 9633 Cases from a Referral Center.

Purpose: To describe the epidemiology of ocular and periocular tumors in patients presenting to a multi-tier ophthalmology hospital network in India using the electronic medical records (EMRs) system.

Methods: A retrospective, observational, referral, hospital-based study of 1,142,098 patients. The data were collected using the in-house developed EyeSmart EMR system.

Spheno-orbital Lesions-A Major Review of Nonmeningioma Causes.

Purpose: To review the imaging features of the broad range of nonmeningioma lesions of the greater wing of the sphenoid (GWS) bone and adjacent orbit to assist clinicians in differentiating these lesions from each other and from the most common lesion of the GWS and adjacent orbit, meningioma.

Methods: We reviewed 32 cases of spheno-orbital lesions involving the GWS from our own practice, as well as 109 published cases (total 141), with emphasis on available imaging features on computerized tomography (CT) and MRI. Features that might assist in differentiating meningioma from its mimics were analyzed for each lesion, including the presence of an osteoblastic or hyperostotic response, bone erosion or osteolysis, homogeneous hypo- or hyperintensity on T2-weighted MRI, leptomeningeal involvement, and the absence of a "dural tail" on contrast-enhanced MRI.

[Fatty Density and Air].

Both fat and air have lower attenuation than water on CT images. Excluding ruptured dermoid cysts, a majority of intracranial fats have no clinical significance. In contrast, intracranial air sometimes indicates serious conditions.

Frontotemporal dermoid cyst with incomplete dermal sinus tract in an adult: A case report.

Background: Non-midline supratentorial dermoid cyst with dermal sinus tract has been rarely reported especially in adults. We recently experienced a noteworthy patient with frontotemporal dermoid cyst with incomplete dermal sinus tract.

Case Description: A 43-year-old female presented with recurrent subcutaneous mass in the left superolateral orbital region.

Clinicopathological analysis of 719 pediatric and adolescents' ocular tumors and tumor-like lesions: a retrospective study from 2000 to 2018 in China.

Aim: To describe the clinicopathologic features and classification of pediatric and adolescent ocular tumors and tumor-like lesions.

Methods: A total of 719 cases of pathologically confirmed ocular tumors and tumor-like lesions in a pediatric population from two academic institutions over an 18-year period were retrospectively analyzed. The main outcome measures were the clinical and pathological features of the cases.

RESULTS OF 15 YEARS OF COLLABORATION BETWEEN THE DEPARTMENTS OF OPHTHALMOLOGY AND STOMATOLOGY IN ONCOLOGICAL SURGERY OF THE ORBIT: A DIAGNOSTIC AND THERAPEUTIC APPROACH.

Aim: To report an overview of the most frequent tumors of the orbit, suggest diagnostic approach and possible solution according to experience with own cohort of patients.

Epidermoid and Dermoid Cysts of the Head and Neck.

Epidermoid and dermoid cysts (ECs and DCs) are congenital anomalies occurring in areas of embryonic fusion. Their incidence in the head and neck region is low and ranges from 1.6% to 7%.

Masquerades of Acquired Dacryocystocele.

Introduction: Dacryocystocele can be congenital or acquired and acute or chronic, based on underlying pathology. An inferomedial anterior orbital mass lesion can masquerade an acquired dacryocystocele with similar symptomatology; however, the treatment varies. Hence, a careful examination of the swelling to differentiate these masquerades is needed to ensure rightful treatment.

A Case Series of Intramuscular Orbital Choristomatous Cysts.

Intramuscular choristomatous cystic lesions within the orbit are rare but may require removal due to their volume effects. The authors describe 2 such cases of intramuscular cysts in adult patients. Both patients presented with symptoms due to local mass effects with swelling, proptosis and diplopia.
