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.

Large congenital myopericytoma of the lower eyelid.

Congenital fibrous soft tissue tumors in the eyelids are exceptionally rare, with only seven cases of neonatal myofibromas reported. Myopericytoma, a variant with pericytic differentiation, has not previously been described in neonatal eyelid tumors. This report details a case of a massive congenital myopericytoma in a newborn's lower eyelid. The lesion had a broad area of adhesion to the anterior lamella of the lid. After resection, when the child was 11 days old, the resulting defect was successfully reconstructed with a V-Y type perforator-based flap.

Standard and modified glabellar flap for medial canthus reconstruction following mass removal in three dogs and two cats.

PURPOSE: To describe the surgical technique and clinical outcomes of the glabellar flap and its modification for the reconstruction of the medial canthus following resection of tumors in three dogs and two cats. METHODS: Three dogs (7-, 7-, and 12.5-year-old mixed breeds) and two cats (10- and 14-year-old Domestic shorthair) presented with a 7-13 mm tumor affecting the eyelid and/or conjunctiva in the medial canthal region. Following en bloc mass excision, an inverted V-shaped skin incision was made in the glabellar region (i.e., the area between the eyebrows in humans). The apex of the inverted V-shaped flap was rotated in three cases, whereas a horizontal sliding movement was performed in the other two cases to better cover the surgical wound. The surgical flap was then trimmed to fit the surgical wound and sutured in place in two layers (subcutaneous and cutaneous). RESULTS: Tumors were diagnosed as mast cell tumors (n = 3), amelanotic conjunctival melanoma (n = 1), and apocrine ductal adenoma (n = 1). No recurrence was noted in a follow-up time of 146 ± 84 days. Satisfactory cosmetic outcome with normal eyelids closure was achieved in all cases. Mild trichiasis was present in all patients and mild epiphora was noted in 2/5 patients, but there were no associated clinical signs such as discomfort or keratitis. CONCLUSIONS: The glabellar flap was easy to perform and provided a good outcome in terms of cosmetic, eyelid function, and corneal health. Postoperative complications from trichiasis appear to be minimized by the presence of the third eyelid in this region.

Solitary fibrous tumor of the orbit in a 1-year-old patient: a case report.

Solitary fibrous tumors (SFTs) are rare neoplasms of mesenchymal origin. While the mean age of presentation is 58 years old, we report the case of the youngest documented patient with an SFT of the orbit. A 13-month-old child was evaluated for eyelid asymmetry and then referred to the oculoplastic service. On examination, a soft tissue mass of the right inferomedial orbit was observed. MRI demonstrated a well-circumscribed, extraocular lesion in the inferomedial right orbit, potentially fibrous in nature. Excision was performed without complications. Pathologic examination demonstrated fibrous tissue proliferation with a staghorn vascular pattern, as well as benign fibrous cells with tapering nuclei and abundant pericellular reticulin. Immunohistochemistry (IHC) demonstrated that the cells stain diffusely positive for CD34 and vimentin. With the MRI findings, pathology, and IHC, the diagnosis was confirmed to be SFT. SFTs of the orbit, although rare, may occur in the pediatric population.

Atypical presentation of invasive myoepithelioma in a pediatric patient.

A 15-year-old girl presented with a mobile lesion with yellowish hue on the posterior lamella of the right lower eyelid adjacent to the punctum. Four years prior, a lesion thought to be a chalazion was excised from the same location. There was subsequent progressive painless enlargement. The patient ultimately underwent an internal excision of the mass. Histopathology demonstrated infiltrative nests and cords of epithelioid and plasmacytoid cells with abundant eosinophilic myxoid-collagenous stroma along with focal infiltration of skeletal muscle with immunohistochemical staining consistent with an invasive myoepithelioma of mixed-cell type. Given concern for invasive disease, the patient underwent subsequent Mohs resection resulting in a 25% full thickness eyelid defect, which was repaired with direct closure of the wedge defect. There has been no recurrence of the disease for 7 months since the Mohs resection. This case illustrates the atypical presentation of an invasive myoepithelioma of the eyelid in a pediatric patient.

Eyelid malignancies in young individuals: clinical peculiarities.

OBJECTIVE: The incidence of malignant eyelid tumors is considerably increasing, even in young patients. The purpose of this study was to identify particularities in individuals under 40 years of age affected by eyelid malignancies. METHODS: Clinical charts of patients under 40 years of age who underwent eyelid tumor excision from 2014 to 2020 in two reference centers, one in Brazil and one in the USA, were reviewed. Demographic and outcome measures included: age, gender, skin phototype, comorbidities, diagnosis, time until diagnosis, lesion location, recurrence and metastasis. In addition, associated characteristics, including chronic sun exposure, intentional tanning (outdoor or artificial), history of smoking, use of sunscreen, family history of skin cancer and exposure to pesticides or herbicides, were reviewed. RESULTS: A total of 24 malignant eyelid tumors from 17 patients were identified. Twelve (70.6%) patients were female, and the most prevalent tumor was basal cell carcinoma (62.5%). Three (17.6%) patients had xeroderma pigmentosum and presented with multiple lesions. Family history of skin cancer was reported by 47% of patients. Prolonged sun exposure was reported by 41.2%; history of smoking and intentional tanning were reported by 23.5 and 17.6%, respectively, and might have played a role in carcinogenesis. CONCLUSIONS: Although uncommon in young subjects, eyelid malignancies present some peculiarities in individuals under 40 years of age. Our results suggest that women with family history of skin cancer and history of chronic exposure to ultraviolet radiation are at risk. Association with genetic syndromes is also relevant among younger age groups.

Ten-year epidemiological study of ocular and orbital tumors in Chiba University Hospital.

BACKGROUND: The purpose of this study is to determine the epidemiology of tumors of the ocular adnexa and orbit in Japan. METHODS: We conducted a retrospective study on the histopathological reports in the medical records of the Chiba University Hospital from April 2009 to March 2019. Three hundred and seventy two records were examined. In addition, we examined the annual changes in the major types of tumors including malignant lymphomas and IgG4-related diseases (IgG4-RDs). RESULTS: There were 270 conjunctival or eyelid tumors with 166 benign and 104 malignant. There were 102 orbital tumors with 55 benign, 47 malignant tumors, and 21 cases of IgG4-RDs. Ten cases of adenoma (2.7%), another benign tumor, was also diagnosed. The major malignant tumors were malignant lymphoma in 74 cases, sebaceous gland carcinoma (SGC) in 28 cases, basal cell carcinoma in 15 cases, and squamous cell carcinoma in 8 cases. The SGCs were the most common malignant eyelid tumor at 54%. Among the malignant lymphomas, extranodal marginal zone lymphomas of the mucosa-associated lymphoid tissue type, MALT lymphomas, was the most common at 51 cases and the second most common was the diffuse large B-cell lymphoma at 11 cases. The ratio of MALT lymphomas to that of all malignant lymphomas increased significantly with years. The serum IgG4 values were measured more often in the last 5 years (70%) than in the former 5 years (33%). CONCLUSIONS: We conclude that malignant lymphoma is a major malignant tumor in Japan and pathological biopsies should be done proactively to prevent missing IgG4-positive MALT lymphomas.

Advancements in the repair of large upper eyelid defects: A 10-year review.

PURPOSE: The reconstruction of large (>50%) upper eyelid margin defects can be technically challenging, with multiple approaches described in the literature. We sought to review the recent literature for new techniques or modifications to existing techniques. METHODS: We conducted a Pubmed search for technique papers on the reconstruction of large upper eyelid defects published within the past ten years with a minimum of four patients. RESULTS: We identified ten articles, and divided them into techniques that use a bridging flap from the lower eyelid and those that do not. The number of upper eyelids repaired in each article ranged from 4 to 17. Most techniques could be considered either a modification of the Cutler-Beard technique or a novel anterior lamella flap laid over a graft for the posterior lamella. Postoperative complications included upper or lower eyelid cicatricial retraction, trichiasis, entropion, and lagophthalmos. CONCLUSIONS: Surgeons continue to innovate for this challenging reconstructive surgery. Overall, the trend was to use a graft, most commonly tarsoconjunctiva from the contralateral upper lid, to replace the posterior lamella, and a skin flap, from the lower eyelid or from the adjacent periorbital area, to replace the anterior lamella. Bridging techniques utilized the skin; the skin, orbicularis, and conjunctiva; or a tarsoconjunctival flap from the lower eyelid. Non-bridging techniques generally used a tarsoconjunctival or substitute graft for the posterior lamella, and a skin flap for the anterior lamella.

Solitary fibrofolliculoma of the upper eyelid in a 68-year old female: a case report.

BACKGROUND: Fibrofolliculoma is a benign, perifollicular, connective tissue tumor, and it usually arises in the form of multiple lesions, but rarely as a solitary lesion. We report a case of solitary fibrofolliculoma on the eyelid. CASE PRESENTATION: A 68-year-old female presented with an asymptomatic mass on the right upper eyelid. The lesion appeared as a flesh-colored, dome-shaped, smooth nodule being the size of 5 × 5 × 4 mm, with eyelashes protruding from the surface, and located on the upper lid margin. Shave excision was performed, and the diagnosis of fibrofolliculoma was confirmed finally through histological exam. CONCLUSIONS: Solitary fibrofolliculomas rarely arises on the eyelid. However, it should be suspected when a flesh-colored and doom-shaped lesion of the eyelid is encountered. The benign tumor on the lid margin can be removed by shave biopsy.

Severe upper eyelid mass in a patient with mycosis fungoides.

Mycosis fungoides is a cutaneous T-cell lymphoma that has been rarely reported to involve ocular structures. Ophthalmic manifestations usually appear in advanced disease. A case of a 58-year-old man presenting with progressive, full thickness, giant upper eyelid mass is presented. The patient had a long history of recurrent tumoral lesions on the trunk and limbs, previously diagnosed as mycosis fungoides. The histopathological examinations of eyelid tumor supported the diagnosis of mycosis fungoides. The mycosis fungoides was stage as IIB (T3N0M0B0) by TNMB classifications and referred to the Hematology and Radiation Oncology clinics. The importance of ophthalmic involvement is being seen in advanced or refractory cases, and there is a possible relation between mycosis fungoides and poor prognosis by being an early indicator of systemic involvement.

Epibulbar complex choristoma with simultaneous involvement of eyelid: a case report.

BACKGROUND: Epibulbar complex choristoma, a rare congenital epibulbar tumor, has many diverse forms. Reviewing the literature, it can present clinically as either a circumferential or isolated epibulbar mass, limbal tumor, lateral canthal mass, aggregate of ectopic cilia in the upper eyelid, eyelid mass mimicking chalazion, or lacrimal caruncle mass. The management depends on the extent of involvement, the risk of amblyopia, and cosmetic concerns. Here, we report an atypical presentation of epibulbar complex choristoma with simultaneous eyelid involvement. CASE PRESENTATION: A 1-month-old full-term boy was brought to our clinic with congenital epibulbar mass of the right eye with simultaneous eyelid involvement. Dilated fundus examination was unremarkable. Survey for linear nevus sebaceous Jadassohn was negative. Due to concerns of possible amblyopia and cosmetics, lamellar keratectomy, sclerotomy, and conjunctivoplasty were performed to remove the epibulbar lesion. The eyelid defect was reconstructed with 6-0 Vicryl sutures. Histopathological examination reported complex choristoma. Upon three-year follow-up, low astigmatism and favorable cosmetics results were achieved. CONCLUSIONS: Congenital complex choristoma can present clinically as an epibulbar mass with eyelid involvement. The management depends on the extent of involvement, the risk of amblyopia, and cosmetic concerns. The method of eyelid reconstruction should be tailored according to the residual eyelid defect.

Eyelash hair transplantation with strip composite eyebrow graft: an enhancing technique in tarsoconjunctival flap eyelid reconstruction procedure.

Purpose: To describe and evaluate the eyelash transplantation with strip composite eyebrow graft to improve eyelid anatomy in tarsoconjunctival flap eyelid reconstruction procedure. Methods: Twenty two patients with eyelid tumors managed by local excision and reconstruction using tarsoconjunctival flap reconstruction procedure were included. Eyelash graft was performed during flap division by harvesting a graft from the eyebrow and creating a recipient pocket in the receptor eyelid. Patients had a 1-year follow up. Eyelash orientation and follicle survival rate were recorded. Demographic variables were analyzed with descriptive statistics. For eyelash follicles survival rate assessment, we evaluated the number of follicles found in the first postoperative day with the follicles found at the end of the study using the Wilcoxon signed rank test. P < 0.05 was considered statistically significant. Results: All eyelash grafts showed a good follicle orientation and no cases of eyelashes misdirection toward the eyeball were reported. No statistical differences (p > 0.05) were found in Wilcoxon signed rank test when comparing the number of follicles present at the first postoperative day and the number of follicles present at the 12th postoperative month, meaning that the vast majority of follicles survived at the end of the study. Graft ischemia, necrosis or infection were not observed. Conclusions: Tarsoconjunctival flap is an outstanding option for eyelid reconstruction and eyelash transplantation with an eyebrow composite graft is an excellent procedure to enhance and recreate a normal eyelid.

Ocular sebaceous gland carcinoma: an update of the literature.

PURPOSE: To review and summarize the newest update on ocular sebaceous gland carcinoma (SGC) focusing on diagnosis and treatment. METHODS: A PubMed search was carried out using the terms "Sebaceous Carcinoma", "Meibomian Gland Carcinoma", "Sebaceous Cell Carcinoma", and "Sebaceous Gland Carcinoma". All studies published in English up to October 2017 were included in this review. RESULTS: Globally, the overall incidence of SGC is increasing making it the third most common eyelid malignancy after basal cell carcinoma (BCC) and squamous cell carcinoma. The mainstay of treatment of ocular SGC is wide surgical resection under frozen section or Moh's micrographic surgery control followed by eyelid reconstruction. Based on histopathological features, SGC can be classified according to growth pattern, cell type, and cytoarchitecture. Based on the growth pattern, they can be classified as trabecular, lobular, papillary, and BCC-like. The cell type can be classified as basaloid, basosquamous, and epidermoid. The SGC cytoarchitecture presents either as a nodular or as an infiltrative lesion. Based on immunohistochemistry, the overexpression of ZEB2, BAG3, androgen receptor, and C-erbB-2 oncoprotein is associated with poor prognosis. The tumor is associated with systemic metastasis in 8-14% and death in 10-30%. CONCLUSION: Ocular SGC is an aggressive tumor associated with poor prognosis. Early identification and appropriate treatment may help improve the prognosis. New insight into its pathogenesis and the immunohistochemical profile may lead to the development of new effective treatment strategies, along with traditional therapies.

Extratarsal presentation of chalazion.

PURPOSE: We report a case of atypical, extratarsal chalazion referred with a history of a chronic inflammatory mass found on the edge of the lower eyelid. METHODS: A 3-year-old female developed a small mass on the medial side of the right lower lid in 4-month duration. She was seen by her ophthalmologist and the diagnosis of a chalazion was made. Over the ensuing one month with warm compression, the lesion subsided and the new lesion appeared away from the edge on the lateral eyelid 3 months ago. RESULTS: She underwent surgery and drainage was performed. We found a track, a proof of migration, on the lower tarsal conjunctiva in the medial side of the right eyelid during surgery. CONCLUSIONS: Long-term observation in chalazion may induce migration with tract and express as an atypical chalazion.

Solitary Clear Cell Renal Cell Carcinoma Metastasis to the Eyelid: A Case Report.

Introduction: This study is a case of solitary clear cell renal cell carcinoma (ccRCC) eyelid metastasis in a 66-year-old man as the first sign of a primary tumor. ccRCC usually spreads to the lungs, mediastinum, bones, liver, and brain, while ocular metastases are rare. Case Presentation: Solitary metastasis presented as a solid mass in the central third of the upper eyelid, which has been growing for 3 weeks. Treatment included tumor removal and blepharoplasty. Histopathological examination showed metastasis of clear cell renal carcinoma. A thorough examination revealed a primary tumor on the lower pole of the right kidney. A right nephrectomy was performed, and histopathology showed ccRCC. Postoperative examinations showed no signs of local or systemic disease. Sunitinib malate was administered to the patient. Conclusion: The eyelid metastasis in this case was still solitary and had been discovered before the existence of the primary tumor was known. Ocular metastasis of renal carcinoma is a rare initial manifestation of the disease and therefore requires a multidisciplinary approach in the treatment of these patients.

Masqueraded sebaceous gland carcinoma of the lower eyelid in a young pregnant patient.

The purpose of this case report is to present misdiagnosed sebaceous gland carcinoma of the lower eyelid with rapid growth in a young woman during pregnancy. Eyelid sebaceous gland carcinoma is a relatively rare tumor and a disease primarily of older patients. It occurs more commonly in oriental populations and with a predilection for the upper eyelid. Early diagnosis and appropriate treatment may help improve disease control and patient survival.

The Cutler-Beard flap for upper eyelid reconstruction: Surgical indications revisited.

PURPOSE: To present the long-term outcome of the Cutler-Beard two-stage technique in patients with large full-thickness upper eyelid defects after tumor excision. METHODS: The medical records of 24 patients with large full-thickness upper eyelid defects reconstructed with the Cutler-Beard technique from January 2000 to January 2021 were retrospectively reviewed. All the defects involved ≥ 60% of the horizontal length of the upper eyelid and extended vertically for at least 15 mm from the eyelid margin. Patients with follow-up < 24 months were excluded. Long-term postoperative complications, functional outcome, and patient's satisfaction at the end of the follow-up were evaluated. RESULTS: Patients' age ranged from 36 to 88 (mean 66.0 ± 10.7 years) and 58.3% were females. Seven patients (29.2%) had had previous eyelid surgeries. The most common diagnosis was basal cell carcinoma (62.5%), followed by sebaceous gland carcinoma (12.5%), squamous cell carcinoma (8.3%), and Merkel cell carcinoma (8.3%). The mean duration of follow-up was 53.0 ± 16.9 months. Eleven patients (45.8%) developed upper eyelid entropion: 9 were treated conservatively with a therapeutic contact lens, 2 patients required a third operating stage. Most patients achieved a satisfactory functional and aesthetical outcome at the end of the follow-up. CONCLUSIONS: Although non-bridging techniques are usually favored to reconstruct large upper eyelid defects, the Cutler-Beard bridge flap is a valuable technique in case of large horizontal defects where the vertical gap is greater than 15 mm. Further surgical steps are rarely necessary; however, alternative techniques should be considered following excision of highly malignant tumors.

Functional inferior canalicular reconstruction using a monocanalicular probe after tumor resection of the medial third of the lower eyelid.

PURPOSE: To describe a surgical technique for functionally reconstructing a lacrimal drainage duct and to assess its long-term functionality. METHODS: This observational review includes six cases involving reconstruction of the inferior canaliculus after surgical resection of lower eyelid carcinoma. Following lesion excision with safety margins, the epithelium of the distal portion of the inferior canaliculus is located and intubated with a monocanalicular probe. Subsequently, the eyelid lamellae are reconstructed without displacing the probe. The Monoka collarette is then sutured using a 10/0 nylon suture. Data collection included anatomic pathology of the lesion and data from ophthalmic examinations at each visit (including epiphora, inferior canalicular irrigation, and fluorescein dye disappearance test [FDDT]), as well as stent extrusion or other complications. RESULTS: No complications were observed during the surgeries. The stents remained in place for an average of 4months, with no extrusions prior to removal. The mean follow-up period was 4.8years (SD=2.0), during which no other complications were noted. Only one patient experienced intermittent epiphora, also present in the fellow eye. At the final visit, FDDT was normal in all eyes, and all patients demonstrated patency of the inferior canaliculus upon irrigation. CONCLUSION: Primary reconstruction of an inferior lacrimal drainage duct following tumor resection can be successfully performed, resulting in favorable functional recovery.

Malignant transformation of a putative eyelid papilloma to squamous cell carcinoma in a dog.

A 6-year-old female spayed Chihuahua was presented for the evaluation of generalized pigmented cutaneous masses, one of which was present on the lower right eyelid. The dog was not on immunosuppressive medications and did not have historical or laboratory evidence of underlying endocrine disease, including hypothyroidism and hyperadrenocorticism. Histopathology, immunohistochemistry, and polymerase chain reaction of a cutaneous biopsy from the left antebrachium containing representative lesions confirmed viral papillomatosis. Additionally, histopathology of the antebrachial mass revealed regions of epithelial dysplasia suggestive of possible early transformation to malignancy. Over the course of 5 months, the mass on the right lower eyelid progressed to encompass and efface the majority of the eyelid margin. Additionally, the eyelid tumor had changed from an ovoid, brown pigmented mass to an irregular, flesh-colored mass. At the dog's last recheck examination, a corneal ulcer had developed beneath the irregular dorsal margin of the tumor. Histopathology of the eyelid mass was consistent with squamous cell carcinoma (SCC) and was positive for the presence of papillomavirus using polymerase chain reaction. This report describes the transformation of a putative viral eyelid papilloma into a malignant SCC in an adult dog.

Post-oncological full-thickness eyelid defect reconstruction: An aesthetical overview.

Purpose of the current study was to introduce a new detailed aesthetical subunit (ASU) involvement chart to localize the defect configuration on the eyelids, and, to evaluate the aesthetical and functional outcomes of the post-oncological full-thickness eyelid defect reconstruction surgery by using a modified aesthetical rating guideline. Medical records of subjects who were diagnosed with a primary malignant full thickness eyelid tumor involving the eyelid margin and underwent full-thickness eyelid defect reconstruction surgery between April 2016 and May 2022 were retrospectively reviewed. Age, sex, pathological diagnosis, follow-up time, the ASU of the eyelid involvement, and surgical methods used to reconstruct the anterior and posterior lamella were examined from medical records. The reconstructed eyelid photos were scored according to the modified aesthetical rating guideline to analyze the aesthetical and functional outcomes of the surgeries. A total of 31 subjects were included to the study, and the overall mean aesthetical score was 3.5. Seventeen subjects with aesthetical scores greater than 3.5 were included in the more aesthetically pleasing (AP) group, and 14 subjects with aesthetical score less than 3.5 were included in less AP group. Anterior lamella repair was mainly performed using myo-cutaneous flaps in the more AP group and multiple flap combinations in the less AP group (P: 0.13). Posterior lamella reconstruction was performed using tarso-conjunctival tissue in both groups. In more AP group, tissue scarring, lash line disruption, eyelid thickness, and retraction or ectropion scores were significantly higher when compared with less AP group (P:0.03, P:0.03, P:0.02, and P:0.01, respectively). Subjects with fair eyelash color were significantly more common in more AP group (P: 0.009). The ASU involvement chart and outcomes of the current study may aid novice surgeons to determine which method will provide the best result for an individual patient for full-thickness eyelid defect repair and may offer some insight into the different surgical techniques used for repairing similar wounds.
