Examining treatment strategies for xanthelasma palpebrarum: a comprehensive literature review of contemporary modalities.

Xanthelasma palpebrarum (XP) is the predominant form of cutaneous xanthoma, as it accounts for greater than 95% of cases. It is characterized by the presence of foam cell clusters containing a large amount of low-density lipoprotein (LDL), which are located in the connective tissue of skin, tendons, and fascia. XP lesions commonly present as distinctive yellow-orange macules, papules, or nodules, and are primarily on the upper eyelids as well as the inner canthus. Women are affected twice as often as men, with lesions typically emerging between the ages of 35 and 55. The pathophysiology of XP involves abnormal lipid metabolism and is often associated with hyperlipidemic states like Type II and IV hyperlipidemia, hypothyroidism, weight gain, and fatty diet. Despite the availability of various treatment methods, current XP management lacks standardization, particularly due to limited comparative research. To address this gap, we conducted an extensive literature review of 45 studies published between 2012 to 2023, which provides an updated overview of current XP treatment modalities. This comprehensive analysis will inform researchers and clinicians on the evolving landscape of XP management.

"Demodicosis" Mimicking PreSeptal Cellulitis: Severe Periocular and Facial Inflammation Caused by "Normal" Skin Flora.

Due to their relatively high prevalence and commensalism, the pathogenicity of Demodex mites has been debated. Recent data, however, show Demodex to be associated with skin and ocular surface diseases such as rosacea, blepharitis, and keratitis. Here the authors report the first known case, to the best of the their knowledge, of Demodex infestation mimicking preseptal cellulitis in an adult human. A 29-year-old male bilaterally blind from advanced retinopathy of prematurity presented with a 2-month history of right-greater-than-left upper eyelid and periocular/cheek swelling, redness, and ocular discharge that did not resolve with oral antibiotics or oral steroids. Based on MRI findings, biopsies of the right lacrimal gland, right orbital fat, and right upper eyelid preseptal skin were obtained which revealed marked intrafollicular Demodex mite density and budding yeasts in the upper eyelid skin. This case serves to alert clinicians to this entity that may not otherwise be usually considered in ophthalmic clinical practice.

Unusual Metastasis to Eyelid from Extraocular Merkel Cell Carcinoma.

Merkel cell carcinoma (MCC) is an unusual skin tumor that has a significant rate of distant and local metastases. It is known that primary MCC of the eyelid usually occurs at the upper eyelid. Here we report an unusual case of MCC metastasis to the eyelid. A 63-year-old male was diagnosed with MCC three years earlier after initially presenting with a mass in his right thigh. After histopathological diagnosis, the patient received medical therapy. During treatment, he developed multiple distant metastases and a firm, purple, vascularized lesion on the upper eyelid. We confirmed the lesion was an eyelid metastasis of MCC by histopathological examination and imaging methods. This case shows that extraocular MCC can metastasize to the eyelids, particularly the upper eyelid, where primary periocular MCC usually appears.

Clinical characteristics and surgical outcomes of transcutaneous versus transconjunctival excision of Wolfring gland ductal cysts.

PURPOSE: To analyze the clinicopathological characteristics and surgical outcomes of patients with Wolfring gland ductal cysts (WGDCs). METHODS: A retrospective, consecutive, interventional comparative case series was performed over a period of 7 years. Data on demographic and clinical characteristics, pathological findings and outcomes of surgically excised cysts were collected. A comparison between the transconjunctival and transcutaneous approaches was also assessed. RESULTS: Forty-eight patients (48 eyelids) were included in the final analysis. The most common presenting symptom was painless eyelid swelling (81.3%). The median symptom duration was 11.5 months (IQR, 18.25). The upper eyelid was involved in 31 (64.6%) patients, 29/31 of whom had cysts in a medial or centromedial location. Forty-five (93.8%) cysts were bluish gray and transilluminable with clear contents on lid eversion and a median largest dimension of 22 mm (IQR, 8). A transverse conjunctival fibrotic band was observed along the proximal tarsal border in the cyst area in all patients. Signs of chronic trachoma were noted in 38 (79.2%) patients. Preoperative significant ptosis was present in 28/31 (90.3%) of the upper eyelid cysts. Thirty cysts (62.5%) were excised through the skin, and 18 cysts (37.5%) were excised transconjunctivally. Intraoperative cyst rupture, the need for conjunctival grafting and postoperative residual upper lid ptosis were significantly greater in the transconjunctival group (p = 0.009, p < 0.001, and p = 0.016, respectively). CONCLUSION: The present study highlights the clinicopathological characteristics of a relatively large series of surgically excised WGDCs. Transcutaneous excision of WGDCs has proven to be an effective treatment with fewer adverse sequelae than the transconjunctival approach.

Quantitative analysis of the eyelid curvature in patients with blepharoptosis.

BACKGROUND: The aim of this study was to evaluate the ability of two novel eyelid curvature measurements to distinguish between normal eyes and different severities of blepharoptosis. METHODS: A comparative cross-sectional analysis of upper eyelid curvature was performed for different severities of patients with unilateral blepharoptosis (congenital and aponeurotic) and normal controls. Mean upper lid contour index (ULCI) and area circularity index (ACI) were calculated for each group by dividing the intercanthal distance by upper eyelid margin length (ULCI) and dividing the interpalpebral area by the area of a circle enclosing the eye (ACI). The ratio of each index for the study and fellow normal eye of each patient was also calculated and compared between groups. RESULTS: A total of 106 eyes including 30 eyes in the control group and 25, 27, and 24 eyes in the mild, moderate, and severe ptosis groups were enrolled in the study. ULCI and ACI showed a statistically significant difference between the groups (p < 0.001, p < 0.001). The inter-eye ratio (ULCI-ratio and ACI-ratio) of indices was also significantly different between groups (p = 0.002, p < 0.001). Pairwise comparisons revealed that ACI and ACI-ratio were significantly different between all pairs of study groups. CONCLUSION: The results of our study showed that ACI based on area measurements may distinguish blepharoptosis patients from normal controls and from each other. Including the data from the fellow normal eyes in the form of ratio indices may improve the differentiating power. These results can be useful in designing the optimal eyelid curvature measurements.

Isolated cavernous venous malformation of the eyelid.

Cavernous hemangioma, currently known as "cavernous venous malformation," is a common, benign, non-infiltrative, slowly progressive vascular malformation of the orbit presenting in adults. We report the case of a 9-year-old girl who presented with a painless palpable mass over the right upper eyelid of 7 years' duration. A computed tomography scan of the orbits revealed a heterogeneously enhancing, well-circumscribed mass in the right upper eyelid with no orbital extension. A transcutaneous excisional biopsy with histopathology disclosed cavernous venous malformation. The majority of cavernous venous malformations are intraconal and present in the fourth to fifth decade of life.

Congenital solitary osseous choristoma of the left lateral canthus: a case report.

BACKGROUND: An ocular osseous choristoma is a growth of mature, compact bone in the ocular or periocular soft tissue, and it is the rarest form of ocular choristoma, accounting for only 1.7% of all epibulbar choristomas. CASE PRESENTATION: Herein we present the case of a 20-month-old girl who was referred to the oculoplasty clinic with a progressively growing mass in the left lateral canthus. It had been present since birth without ocular involvement. Upon examination the mass was firm with a smooth surface, measured 9 × 6 × 3 mm, and exhibited no episcleral attachment or ocular involvement. An excisional biopsy was performed, and the histopathological findings were consistent with osseous choristoma of the left lateral canthus. CONCLUSIONS: This report highlights the importance of considering osseous choristoma in the differential diagnosis of eyelid lesions, particularly those that have been present since birth. It also emphasizes the need for further studies investigating associations between osseous choristomas and ocular canthi.

Surgical margins and outcomes for eyelid melanoma: a systematic review and meta-analysis.

No randomized trials exist to inform the peripheral surgical margins or depth of wide excision for eyelid melanoma. We performed a meta-analysis examining surgical margins and Breslow depth for eyelid melanomas. A systematic review was performed in August 2022 using PubMed, Cochrane, and Medline databases (1/1/1990 to 8/1/2022). Inclusion criteria included studies reporting surgical treatment of primary cutaneous melanomas of the eyelid with reported surgical margins. Ten articles were included. The studies were examined by surgical margin size (group 1: ≤ 0.5 cm; group 2 > 0.5 cm and ≤ 1.5 cm) and Breslow depth (group 1: ≤ 1 mm; group 2: > 1 mm). The odds ratio (OR) for local recurrence was 2.55 [95% CI 0.36-18.12], p = 0.18; regional metastasis was 0.70 [95% CI 0.00-23671.71], p = 0.48; and distant metastasis was 2.47 [95% CI 0.00-1687.43], p = 0.66. When examining by Breslow depth, the OR for local recurrence was 0.53 [95% CI 0.14-1.94], p = 0.34; regional metastasis was 0.14 [0.00-176.12], p = 0.54; and the OR for distant metastasis was 0.24 [95% CI 0.01-8.73], p = 0.46. There was a trend toward higher likelihood of recurrence and metastasis in the ≤ 0.5 cm group. Similarly, there is a trend toward higher likelihood of recurrence and metastasis with Breslow depth > 1 mm. A surgical margin of at least 0.5 cm and achievement of negative margins via permanent sections or MMS are likely needed to prevent adverse outcomes. En face sectioning may be a superior method of histological processing for eyelid melanoma.

Contact allergens responsible for eyelid dermatitis in adults.

Allergic contact dermatitis has been established as the most frequent cause of eyelid dermatitis, but it is often misdiagnosed. The purpose of this study was to evaluate the characteristics of patients with eyelid dermatitis who were referred for patch testing. The patients were divided into three subgroups in this retrospective study: patients with only eyelid involvement, patients with involvement of eyelids and other areas, and patients without eyelid involvement. Data was collected on diagnoses, medical history, personal care products and make-up use, occupational dermatitis, and positive allergens. An independent t-test, one-way ANOVA, and chi-squared test were used to analyze the data. A total of 427 patients who referred for patch tests were included in the study. Of these, 139 patients had eyelid dermatitis. Allergic contact dermatitis (ACD) was the most common diagnosis in all three groups referred for patch tests. Use of shaving cream and hair conditioner was significantly higher in patients with only eyelid involvement and nickel sulfate was the most common allergen among them. Patch testing is the gold standard tool in the evaluation of eyelid contact dermatitis, and it is a necessity in the treatment of eyelid dermatitis, for the accurate identification of responsible allergens.

Sebaceous carcinoma with apocrine differentiation arising in a known case of basal cell carcinoma: A rare entity.

Sebaceous carcinoma is a ra malignant tumor of adnexal origin arising from sebaceous glands. It is most commonly seen arising from the eyelids and head and neck. It is predominantly seen in females with an average age of around 65 years. Apocrine differentiation in sebaceous carcinomas is rare but has been reported in the literature. Here, we present a case of sebaceous carcinoma with apocrine differentiation in a 62-year- old female who was a diagnosed case of basal cell carinoma.

Chalazion-mimicked eyelid angiosarcoma in a young Asian with good prognosis: a case report.

BACKGROUND: Angiosarcoma is an extremely rare malignant tumor. So far, only about 42 cases of angiosarcoma involving the eyelids have been reported. Eyelid angiosarcoma occurs more frequently in elderly Caucasian males and is prone to misdiagnosis. We present a case report in a young Asian male patient with eyelid angiosarcoma that was misdiagnosed as a chalazion. CASE PRESENTATION: A 46-year-old South Korean male with no underlying disease had a right lower lid mass. The lesion was initially misdiagnosed as a chalazion at a local clinic, but a diagnosis of eyelid angiosarcoma was made after the first biopsy trial. PET-CT was performed to ensure that there was no metastasis in the whole body. Surgical excision with enough surgical margin was used alone for treatment and reconstruction was performed with a tarsoconjunctival advancement flap (modified Hughes procedure), which helped ensure good cosmesis. No recurrence was observed 4 years and 5 months after the surgery. CONCLUSIONS: The current study presents the first case of chalazion-mimicked eyelid angiosarcoma in a young Asian male aged under 50 years. This case shows that even if a benign eyelid disease is suspected in a young patient, an incisional biopsy must be performed to confirm whether the lesion is malignant. Since the prognosis is good for the case of eyelid angiosarcoma, if there is no clear evidence of distal metastasis, surgical resection should be performed with an enough safety margin.

Pigmented Squamous Cell Carcinoma In Situ of the Eyelid.

This case report describes a diagnosis of pigmented squamous cell carcinoma in situ in a female patient aged 61 years who presented with a pigmented lesion on her medial canthus that had been growing over a 2-year period.

Clinical features and management of eyelid margin nevi.

PURPOSE: Acquired melanocytic nevi are common eyelid lesions; however, their clinical presentation is not well documented. METHODS: In this retrospective study, clinical records were reviewed in patients evaluated between 2005 and 2022. RESULTS: Eyelid margin nevi (n = 150) were more commonly excised in female (78%) and Caucasian (86%) patients. Change in appearance/size were frequent presenting complaints, and 17% experienced ocular symptoms. Referring diagnosis included other benign lesions (11.3%), and concern for malignancy (16.7%). Many individuals (38.7%) noted their lesion for ≤5 years. Nevi were distributed across the 4 margins (9% peripunctal), and 88% had a regular base. Visible pigmentation was more common in non-Caucasians (95.2%) than Caucasians (41.1%). Lashes grew through 60.7% of nevi and were often misdirected.Nevi were treated with superficial excision and cauterization. Histologic subtypes included: dermal (86.6%), compound (9.4%), blue (2.7%), junctional (0.7%), lentiginous dysplastic (0.7%). An irregular base (p=0.042) and pigmentation (p=0.056) were more common in compound than dermal nevi. Lash line quality and appearance were improved in the majority of patients returning for follow-up, although postoperative trichiasis, marginal erythema, and residual pigmentation were observed. CONCLUSIONS: Melanocytic nevi commonly involve the eyelid margins and have a variety of presentations and appearances. Existing nevi can change, and new lesions appear throughout adulthood. Stable, benign appearing nevi can be observed. Shave excision provides a diagnosis and improved appearance for symptomatic or suspicious lesions, with few serious complications. Malignant transformation is rare, although evidence for recurrence warrants further evaluation.

Comparison of the clinical characteristics of benign and malignant eyelid lesions: an analysis of 1423 eyelid lesions, compared between ophthalmology department and plastics department.

PURPOSE: Oculoplastic surgeons excise and reconstruct eyelid tumors, although plastic surgeons have traditionally managed these cases. Current demand of this surgery is growing, and planning referral services is a health management necessity. This pilot study retrospectively reviewed same population eyelid specimens excised by both disciplines comparing data. METHODS: Clinical and epidemiologic features of 1423 eyelid lesions biopsied between 2015- 2020 in Emek Medical Center (EMC), Israel were reviewed. RESULTS: Among 1423 specimens, 1210 (85.0%) were benign and 213 (15.0%) were malignant/pre-malignant. Mean age at diagnosis was significantly higher in malignant tumors than in benign tumors (76 and 59 years respectively, p value < 0.001). The most common benign eyelid lesions were soft fibroma (20.1%), seborrheic keratosis (11.0%) and melanocytic nevus (10.3%). The most common malignant/pre-malignant eyelid tumors were basal cell carcinoma (BCC) (9.2%), actinic keratosis (2.6%) and Bowen's disease (1.9%). Ophthalmology removed 37 malignant/pre-malignant lesions (5.4%) out of 683 compared to plastics removing 142 malignant/pre-malignant lesions out of 740 (19.2%) specimens. Eyelid malignancy in the plastics department was significantly higher than in the ophthalmology department (p value < 0.001). 270 (70.0%) lesions caused by UV exposure were removed by plastics and 116 (30.0%) were removed by ophthalmology (p value < 0.001). CONCLUSIONS: Eyelid lesions in patients aged 76 or older are more likely to be malignant. Ophthalmology eyelid specimens in younger patients are more commonly benign and related to inflammation. Specimens from the plastics department are more commonly malignant, related to UV-exposure, and are from older patients. This difference may be due to a misconception that plastic surgeons have more eyelid cancer reconstruction experience than oculoplastic surgeons, or less awareness of the oculoplastic expertise available today.

Squamous cell carcinoma of the eyelid.

Eyelid squamous cell carcinoma is a major type of rare eyelid cancer, together with basal cell carcinoma and sebaceous gland carcinoma. It is a painless disease that progresses slowly and is often detected by the appearance of nodules or plaques. Risk factors include exposure to ultraviolet light, fair skin, radiation and human papillomavirus infection. The standard treatment is surgical removal, and in cases of orbital invasion, orbital content removal is required. If sentinel node biopsy reveals a high risk of lymph node metastasis, adjuvant radiotherapy may be considered. Local chemotherapy, such as imiquimod and 5-fluorouracil, may be used for eyelid squamous cell carcinoma in situ. When surgery or radiotherapy is not recommended for distant metastases or locally advanced disease, drug therapy is often according to head and neck squamous cell carcinoma in Japan. The treatment often requires a multidisciplinary team to ensure the preservation of function and cosmetic appearance.

Surgical Correction of Cicatricial Lower Eyelid Retraction: A Systematic Review.

BACKGROUND: Cicatricial lower eyelid retraction is a challenging condition. It involves scarring of the lower eyelid, which causes it to retract and expose the sclera. This can lead to complications such as dry eye syndrome and corneal melting. It can be caused by trauma, burns, or previous eyelid surgery. Detailed assessment and understanding of eyelid anatomy and retraction are critical for successful surgical planning. Dynamic and static examinations of the eyelid including measurements of the lower eyelid margin reflex distance (MRD2) and scleral show are also essential to determine the appropriate treatment approach. METHODS: A systematic review was conducted using Medline, Scopus, and Cochrane databases with keywords related to cicatricial lower eyelid retraction. The publication language was limited to English after 2000. A total of 29 articles were included for data extraction and analysis. RESULTS: The main surgical techniques include tarsoconjunctival grafts, spacers, midface lift, and lateral canthal tendon suspension, although no single procedure has been universally recognized as the gold standard. New innovations such as synthetic grafts and xenografts are being explored for their potential in eyelid reconstruction. Severe cases, defined as those with inferior scleral show greater than 2 mm, may require a combination of reconstruction methods. CONCLUSIONS: Correcting cicatricial lower eyelid retraction is a major challenge in oculoplastic reconstruction. The surgical approach should be individualized, considering the pathologies and etiologies of lid retraction. In-depth knowledge and careful surgical planning are essential for best outcomes. There is no gold standard technique, and postoperative outcomes, complications, and management vary depending on the surgical approach used.

Use of chalazion clamp for excision of the eyelid margin lesion.

PURPOSE: Reconstruction after eyelid lesion excision is very important. It calls for preserving normal eyelid function for the protection of the eye and restoring good cosmesis. It is important to precisely align the tarsal plate. However, the unique anatomy of eyelids often makes haemostasis difficult and surgical field obscured. We report an effective method to solve this problem. METHOD: This retrospective study included 25 patients who underwent eyelid margin lesion excision using the chalazion clamp between March 2020 and October 2021. The chalazion clamp is placed on the desired location and tightened, providing a bloodless field for eyelid lesion removal. Without bleeding, visibility of the cut edges is improved considerably. It facilitates anatomical anastomosis of the tarsal plate. RESULTS: All 25 patients maintained normal eyelid function and good cosmesis, with no recurrence during the follow-up period. CONCLUSION: The use of the chalazion clamp during excision of the eyelid margin lesion could stabilize the eyelid, protect the eyeball from accidental injury and, and provide a clear bloodless operative field. It can ensure the neatness of the cut edges and offer better incision alignment for suture. It also avoids wasting too much time on haemostasis, without additional expensive equipment.
