A clinical photograph showing the periorbital region of a patient with bilateral upper eyelid swelling and mechanical ptosis. The swelling is asymmetrical, being significantly more pronounced on the right side, where the mass effect has caused inferior dystopia (downward displacement) of the globe. The skin of the upper eyelids is hyperpigmented and appears firm and lobulated, consistent with underlying orbital masses. White arrows point to small, discrete, flesh-colored papular skin lesions located on the upper eyelids and supraorbital brow area. The clinical presentation is indicative of bilateral orbital involvement, which in this context represents diffuse large B-cell lymphoma (DLBCL) affecting the lacrimal glands. The image illustrates the external ocular manifestations of orbital lymphoma, including proptosis, lid edema, and mechanical secondary effects on eye position and eyelid function.

This clinical photograph shows a close-up, frontal view of an adult's face, highlighting significant facial asymmetry due to a mass in the left periocular region. The left upper eyelid displays a pronounced, firm-appearing swelling located superior and medial to the globe, consistent with an angular dermoid cyst. This mass causes mechanical ptosis, significantly narrowing the palpebral fissure compared to the unaffected right eye. The skin overlying the swelling appears intact without acute inflammatory signs like erythema or ulceration, though normal eyelid creases are obliterated. In contrast, the right eye serves as a baseline, showing normal eyelid position and periocular anatomy. This image is used to demonstrate the clinical presentation of orbital or adnexal dermoid cysts and their effect on eyelid mechanics and ocular symmetry within ophthalmology and dermatology training.

Clinical photography of the left periorbital skin demonstrating an erythematous, scaly plaque along the upper eyelid margin. The lesion is well demarcated, with red to pink erythema and fine superficial desquamation; mild crusting is present at the center and along the lid edge. Surrounding skin shows mild irritation without confluent swelling. The ocular surface appears not to be visibly involved; no purulent discharge is evident. The pattern is unilateral, localized to the periorbital region, compatible with common inflammatory dermatoses affecting the eyelid, rather than a primary ocular pathology. Differential diagnoses include seborrheic dermatitis of the eyelids, atopic or contact dermatitis, blepharitis with dermatitis, and less likely psoriasis or fungal infection. The image emphasizes surface features such as hyperemia, scaling, fissuring, and crusts, with the lid margin appearing slightly thickened. This clinical photo supports assessment of periorbital dermatitis, eyelid dermatitis, and blepharitis variants, and can guide topical therapy decisions. While histology is not available from a photograph, correlating with history and, if needed, skin scraping or biopsy could clarify diagnosis. Potential clinical uses include education, documentation of eyelid dermatitis severity, and monitoring response to topical steroids, calcineurin inhibitors, or antiseborrheic shampoos. This image supports teaching, case discussions, and diagnostic reasoning sessions.

Clinical photograph of a patient's face showing a comparison between the right and left ocular regions. The right upper eyelid exhibits significant pathology characterized by marked edema (swelling), diffuse erythema, and complete mechanical ptosis, where the eyelid droops to entirely obscure the globe. The swelling appears localized to the right upper eyelid and superolateral orbital area, suggestive of a firm, underlying infiltrative mass. In contrast, the left eye appears normal with clear anatomical landmarks, healthy skin texture, and proper eyelid positioning. The image illustrates a unilateral orbital or eyelid inflammatory process, often associated with infectious or granulomatous conditions such as orbital cellulitis or zygomycosis (e.g., Saksenaea vasiformis). This visual is intended for ophthalmology and dermatology education to demonstrate clinical manifestations of severe eyelid lesions and differential diagnosis of mechanical ptosis.

This set of clinical photographs illustrates severe ocular pathology in the left eye, later confirmed as orbital squamous cell carcinoma. Panel A shows significant erythematous swelling of the left upper eyelid with the loss of normal skin folds (dermatoglyphs), leading to mechanical ptosis. Panel B provides a profile view of a large, infiltrating mass measuring approximately 30 mm x 20 mm within the upper eyelid; the lesion exhibits ill-defined boundaries, firm texture, and overlying skin hyperpigmentation. Panel C demonstrates secondary ocular involvement including severe bulbar conjunctival chemosis (edema), conjunctival hyperemia, and corneal conjunctivalization. These findings represent advanced orbital malignancy with massive space-occupying effects, resulting in globe compression and severe secondary glaucoma (46.5 mmHg). The images provide high-level educational value for ophthalmology and oncology specialties regarding the clinical presentation of aggressive orbital adnexal tumors.

A clinical photograph of a pediatric male patient demonstrating significant facial asymmetry due to a large, diffuse swelling on the right midface. The swelling originates from the right maxilla and extends from the infraorbital region down to the mandible, and laterally from the nasolabial fold toward the preauricular area. Visually, the mass causes a superior displacement of the right lower eyelid and eyeball (proptosis/exophthalmos) and an upward elevation of the right corner of the mouth. The overlying skin appears intact with normal color and texture, suggesting a deep-seated, slow-growing pathology. The case is consistent with an odontogenic tumor or fibro-osseous lesion of the maxilla, such as an odontogenic myxoma, causing extensive bony expansion and secondary displacement of orbital and perioral soft tissue structures. This image serves as a clinical example of maxillo-facial pathology and its impact on cranial symmetry and orbital alignment.

This clinical photograph shows a close-up frontal view of a patient's face, specifically focusing on the nasal and midface region. A prominent, localized swelling is visible on the left side of the nasal dorsum, extending toward the medial infraorbital area. The mass causes a significant loss of facial symmetry, with a visible bulge that displaces the normal contours of the nose and the lower medial eyelid. The overlying skin appears slightly erythematous with subtle fullness, though it remains intact without ulceration. This presentation is characteristic of a soft tissue tumor or cystic lesion of the sinonasal region, such as a solitary myofibroma (SNM), as suggested by the clinical history of recurrence and rapid growth. The image effectively demonstrates the clinical manifestation of a midfacial mass and its impact on regional anatomical landmarks, including the nasal bone and lacrimal drainage pathway.

This clinical photograph shows the left periocular region of a patient, demonstrating significant soft tissue swelling at the superolateral angle of the left orbit. The mass is located in the anatomic region of the lacrimal gland, presenting as a visible fullness that distends the overlying skin. Associated clinical findings include a mechanical ptosis of the left upper eyelid, resulting in a narrowed palpebral fissure. The skin overlying the swelling appears slightly erythematous or discolored compared to the surrounding facial tissue. There is no evidence of significant proptosis or globe displacement visible from this frontal-oblique view. This clinical presentation is typical for orbital adnexal lesions, such as a lacrimal gland tumor or inflammatory myofibroblastic tumor (IMT). The image serves as an educational example of orbital mass localization and its secondary effects on eyelid positioning.

This clinical photograph shows a pediatric patient with a massive, firm, and expanding swelling on the left side of the face and neck. The mass involves the left orbital, parotid, and submandibular regions, causing significant facial asymmetry. Visible cutaneous findings over the tumor include prominent superficial telangiectasia (vascular markings) and ecchymotic discoloration (bruising) at the inferior aspect of the lesion. The left eye exhibits severe proptosis with conjunctival chemosis, erythema, and eyelid edema, consistent with orbital involvement. From an educational perspective, the image illustrates advanced-stage extraocular retinoblastoma following local recurrence. This represents a critical case study in pediatric oncology and ophthalmology, emphasizing the progression of intraocular malignancy into regional soft tissues when primary management is delayed or inadequate. The clinical presentation is highly suggestive of extensive lymph node and soft tissue metastasis in the cervical region.

This composite image consists of a clinical photograph and a diagnostic radiological scan illustrating a chronic orbital dermoid cyst. Figure A is a clinical photograph of an elderly patient's right periorbital region. It demonstrates significant mechanical ptosis of the right upper eyelid and a visible mass in the lateral orbital area, causing focal swelling and redundant skin. Figure B is an axial computed tomography (CT) scan of the head at the level of the orbits. The scan reveals a well-circumscribed, hypo-dense mass in the right superolateral orbit. There is clear evidence of chronic pressure-related bone remodeling and erosion, specifically involving the frontal bone and frontosphenoidal suture area, resulting in an indented orbital margin. The clinical and radiological findings are consistent with a long-standing, slow-growing orbital cyst, such as a dermoid cyst, which has caused secondary structural deformation of the surrounding bony architecture.

Clinical photograph of a pediatric patient presenting with an infected nasal dermoid cyst. The primary pathology is a prominent midline mass located on the nasal dorsum/glabella region. Visually, the mass exhibits an erythematous, reddish-purple hue with an irregular, textured surface suggestive of acute inflammation or secondary infection. Associated periorbital edema and soft tissue swelling are evident around the lesion. The image also demonstrates medical support and devices, including a tracheostomy tube positioned beneath the chin, a pacifier in the mouth, and a headgear strap, indicating possible complex airway management or comorbid conditions. This visual serves to educate on the typical midline presentation of congenital nasal dermoid cysts and the clinical signs of superimposed infection in a surgical candidate.

This intraoperative clinical photograph captures the surgical excision of a dermoid cyst in a pediatric patient. The image shows the periorbital region, specifically the lateral aspect of the left eyebrow, where a horizontal incision has been made. Protruding through the surgical opening is a well-circumscribed, spherical, yellowish-white cystic mass, typical of a dermoid cyst containing keratin and sebaceous material. The surrounding skin is clean and shows minimal erythema at the incision margins. The patient is prepared in a sterile field with blue surgical drapes, and the eyes are secured with protective adhesive tape. Surgical instruments are visible in the periphery, indicating an active operative procedure. This visual serves as an educational example of the anatomical presentation and surgical management of common benign head and neck neoplasms in children, highlighting the superficial location and distinct morphology of the cyst relative to local tissues.

Clinical photograph of the right periorbital and midface region demonstrating features of preseptal cellulitis. The image shows significant erythema and marked edema (swelling) extending across the forehead, nose, and periorbital areas. The right upper and lower eyelids are severely edematous, characterized by chemosis (conjunctival swelling) that restricts the visualization of the globe. A prominent yellowish crust is visible along the lid margins, suggesting the presence of dried purulent exudate or discharge. The skin appears tense and inflamed, consistent with an acute infectious or inflammatory process. This visual serves as an educational example of the clinical presentation of orbital or preseptal infections and the associated soft tissue manifestations such as eyelid crusting and severe chemosis.

A comparative series of four axial Computed Tomography (CT) scans of the orbits, illustrating the radiological progression of orbital complications typically following sinusitis, categorized by severity. Panel A (Eyelid Cellulitis) shows preseptal soft tissue swelling and eyelid edema with preserved clarity of the post-septal orbital fat. Panel B (Orbital Cellulitis) demonstrates increased density and 'dirty' stranding of the intraconal and extraconal orbital fat, indicating post-septal inflammation without a focal collection. Panel C (Subperiosteal Abscess) reveals a localized, rim-enhancing fluid collection adjacent to the medial orbital wall (lamina papyracea), displacing the medial rectus muscle laterally. Panel D (Orbital Abscess) displays a more advanced, poorly defined heterogeneous collection within the orbital soft tissues, causing significant proptosis and mass effect. These diagnostic images provide clinical examples of the Chandler classification for orbital infections, emphasizing the importance of identifying organized abscesses for surgical planning.

A series of three clinical photographs arranged as a vertical timeline demonstrating the progression of left-sided periorbital cellulitis in a pediatric patient. The first image ('On admission') shows moderate edema of the left upper and lower eyelids with mild erythema. The second image ('30/6/19') shows a significant increase in inflammatory swelling, characterized by tense, erythematous skin and worsening ptosis of the upper eyelid. The final image ('1/7/19') depicts generalized, severe periorbital edema that almost completely obscures the globe, with the skin appearing stretched and shiny due to underlying inflammation. This timeline illustrates the clinical worsening of preseptal cellulitis despite initial antibiotic treatment, which was later attributed to an odontogenic infection and orbital periosteal abscess. The images serve as an educational tool for identifying the signs of progressing orbital complications, including changes in eyelid morphology, distribution of swelling, and the urgent need for diagnostic imaging like CECT to differentiate between preseptal and orbital cellulitis.

This composite medical image displays clinical and radiological findings in a pediatric patient. Figure A is a clinical photograph showing significant left supraorbital swelling and erythema (indicated by a yellow arrow) involving the left upper eyelid, initially suggestive of preseptal cellulitis. Figure B is an axial enhanced CT scan of the head at the orbital level, demonstrating thickening of the left supraorbital skin and irregular attenuation within the subcutaneous fatty tissue, though the orbital contents appear spared. Figure C is an axial enhanced CT scan of the lower neck/supraclavicular region, revealing a pathologically enlarged left supraclavicular lymph node with a characteristic low-density (hypodense) center, suggesting necrotic changes or metastatic involvement. These findings are pedagogically used to illustrate the clinical presentation of metastatic neuroblastoma, which can mimic inflammatory conditions like orbital cellulitis through orbital and lymph node spread.
