Solitary eosinophilic granulocytic sarcoma in a dog.

A 6-year-old male golden retriever presented with swelling of the left upper eyelid of 2 months duration, which did not improve following a course of antibiotics. Routine serum biochemistry, complete blood count and diagnostic imaging identified no clinically significant abnormalities. The mass was surgically excised, and histopathologic examination was performed. Eosinophilic granulocytic sarcoma (GS) was diagnosed based on the results of histopathology and immunohistochemistry. This is the first report of GS affecting the eyelid of a dog.

[Metastasis in the periocular region]. / Metastase in der periokulären Region.

Orbital and periocular metastatic tumors used to be considered very rare; however, with the constant updating of drugs and detection methods for cancer treatment, new chemotherapies and radiation treatments are being used. The life expectancy of cancer patients has become longer and periocular metastases are becoming easier to detect. Our knowledge of this rare disease of metastases also needs to be updated. This article reviews the incidence, symptomatic presentation, clinical features, diagnostic approaches and current treatment of metastatic tumors of the orbit and ocular adnexa in these patients.

Updates on eyelid cancers.

In this review, we aim to provide an overview of the five most common malignant eyelid tumors with current treatment recommendations based on international guidelines. Particular attention is paid to the clinicopathological correlation and the update with regard to adequate treatment. Newer systemic therapies enrich the existing treatment options, of which complete tumor excision remains the most important therapeutic measure.

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.

Periocular sebaceous carcinoma: updates in the diagnosis, treatment, staging, and management.

Periocular sebaceous carcinoma (PSC) is a rare, aggressive, and potentially metastatic adnexal malignancy. Due to the ability of PSC to resemble several benign and malignant conditions, diagnosis is often delayed or mistaken. In addition, even with a known diagnosis, choosing the right treatment is still an open debate. For this reason, we decided to review the most up-to-date literature on PSC and propose a dedicated procedural protocol to help clinicians when dealing with PSC. A PubMed search was carried out using the terms "Sebaceous Carcinoma", "Adnexal Periocular Cancer", "Sebaceous Carcinoma AND eyelid", "Periocular Sebaceous Carcinoma", and "Ocular Adnexa". Pertinent studies published in English from 1997 up to December 2022 were compared to the selection criteria and if suitable, included in this review. Through the initial search, 84 articles were selected. Of these, 36 were included in the final study. Several papers explored different diagnostic and therapeutic strategies regarding PSC diagnosis and management. In light of the current literature review and the multidisciplinary experience of three clinical centers, a dedicated procedural protocol is proposed. PSC diagnosis may be achieved through accurate clinical evaluation, but it requires histopathologic confirmation, which can be challenging. Dermoscopy, in vivo reflectance confocal microscopy, and optical coherence tomography may facilitate PSC clinical examination, while immunohistochemistry stains may support histological diagnosis. Appropriate disease staging is necessary before choosing the treatment, as local disease requires radically different treatment compared to advanced disease. In addition, recent innovations in nonsurgical treatments, including radio-chemotherapy, immunotherapy, and targeted therapy, may be a viable option in the most challenging cases.

Endocrine mucin-producing sweat gland carcinoma of the eyelid - A diagnostic challenge.

ABSTRACT: Skin adnexal or sweat gland neoplasms are rare adnexal tumors that pose a diagnostic challenge for both ophthalmologists and pathologists. Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is an uncommon low grade carcinoma of eccrine ducts with a predilection to occur in the periocular region in the elderly female. We present a rare case of 65-year-old healthy male who presented with a lobulated mass in the left eye lower lid, clinically suspected as sebaceous gland carcinoma, diagnosed as endocrine mucin-producing sweat gland carcinoma histopathologically.

Recurrence rates of periocular basal cell carcinoma following intra-operative en-face frozen section margin controlled excision.

PURPOSE: To report the margin control process and rate of recurrence of periocular basal cell carcinomas (BCCs) managed by en-face, frozen section margin controlled (FSC), excision by a single surgeon with a 3-year follow-up. METHODS: A retrospective analysis of all histopathologically proven cases of periocular BCC who underwent surgical excision with intra-operative, en-face, FSC, excision by a single surgeon from 2015 to 2019 was performed. Patients with less than 3-year follow-up were offered a virtual appointment to determine possible recurrence. RESULTS: A total of 88 BCC excisions from 86 patients were reviewed. Minimum 3-year follow-up data is available for 73 patients. The most common location and histological subtype was the lower eyelid and nodular BCC, respectively (47% and 83% of cases). Primary BCC (pBCC) comprised 98% (86/88) of cases and recurrent BCC (rBCC) comprised 2% (2/88) of cases. Negative frozen section margins were achieved in 93% (82/88) of excisions on the day of surgery. The overall recurrence rate during this time was 1.4% (1/73) at minimum 3 years. CONCLUSION: Periocular BCC can be managed effectively by en-face, FSC, excision, with a high cure rate and low recurrence rate comparable to alternative excision techniques such as Moh's micrographic surgery. Advantages of en-face excision include same-day excision and reconstruction and reduced theatre time. Primary nodular BCCs with clear margins can be considered for early discharge with advice to self-monitor.

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.

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.

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.

Neoadjuvant Chemotherapy in a Case of Nonresectable Papillary Squamous Cell Carcinoma of the Palpebral Conjunctiva.

The role of neoadjuvant chemotherapy (NACT) in eyelid and orbital malignancies is not well defined. It has been tried with good success in cases of eyelid sebaceous gland carcinoma but there is very limited literature on its role in cases of ocular surface squamous neoplasia. A 54-year-old man presented with gradually increasing swelling of the right upper eyelid for the past 2 years. On examination, a large friable papillary mass was found covering the entire conjunctival surface (T3N0M0). Incisional biopsy from the mass was suggestive of papillary squamous cell carcinoma. There was no lymph node or distant metastasis as confirmed by whole-body positron emission tomography-CT scan. A trial of NACT (3 cycles of paclitaxel and cisplatin) was given and the mass shrunk in size considerably making it amenable to surgical resection. The conjunctival surface healed completely and there was no recurrence at 1 year of follow up. NACT can be tried in unresectable large ocular surface neoplasia to make the tumor more amenable to surgical resection.

Management of periocular keratinocyte carcinomas with Mohs micrographic surgery and predictors of complex reconstruction: a retrospective study.

BACKGROUND: Skin cancer is the most frequent cancer worldwide and the most frequent periocular tumor. Keratinocyte Carcinomas (KC) located in periorificial areas, such as periocular tumors, are considered high-risk tumors. Mohs Micrographic Surgery (MMS) is considered the first line for the treatment of high-risk KC, providing a lower recurrence rate than conventional wide excision. OBJECTIVE: To describe the clinical-pathological features of periocular KC treated with MMS in a tertiary university center in Chile. METHODS: A single-center, retrospective study of patients with KC located on the periocular area, that underwent MMS between 2017‒2022. MMS details were recorded. RESULTS: One hundred thirteen patients with periocular carcinomas were included. The mean age was 59 ± 13 years; 52% were women. The most frequent location was the medial canthus (53%), followed by the lower eyelid (30.1%). The most frequent BCC histology was the nodular variant (59.3%). Regarding MMS, the average number of stages was 1.5 ± 0.7, and 54% of the cases required only 1 stage to achieve clear margins. To date, no recurrence has been reported. Tumors larger than 8.5 mm in largest diameter or 43.5 mm2 were more likely to require complex reconstruction. STUDY LIMITATIONS: Retrospective design and a relatively low number of patients in the SCC group. Possible selection bias, as larger or more complex cases, may have been referred to oculoplastic surgeons directly. CONCLUSION: The present study confirms the role of MMS for the treatment of periocular KCs. Periocular KCs larger than 8.5 mm might require complex reconstruction. These results can be used to counsel patients during pre-surgical visits.
