PRAME (PReferentially Expressed Antigen in MElanoma) has been studied in the various neoplasms as proposed as diagnostic and therapeutic markers. PRAME is expressed in normal sebaceous units and in some sebaceous lesions; however, its utility in sebaceous carcinoma diagnosis has not yet been extensively investigated. \u0000We conducted a 13-year retrospective review of the patients diagnosed with PSC at the National Specialist Ophthalmic Pathology Service in Liverpool. Herein, we report the histomorphological and immunohistochemical (IHC) features of these tumors, particularly PRAME expression in this cohort.\u0000\u0000Methods: Thirty-one PSC cases diagnosed between 2009 to 2022 were retrieved from the histopathology archives. Twenty cases diagnosed as invasive PSC and 11 cases with in-situ PSC were included. The hematoxylin and eosin (H&E) slides and previously-performed IHC slides were reviewed; clinical information data were obtained. Cases with an adequate tissue were also stained for PRAME (PReferentially expressed Antigen in MElanoma) and adipophilin (if not already performed). \u0000\u0000Results: In total, there were 24 females and 7 males diagnosed with PSC, ranging from 55 to 90 years (median, 78 years). The types of specimens received were: 11 conjunctival mapping biopsies, 19 excisions/wedge resections, and 1 orbital exenteration. The eyelid was the commonest site involved (n=24), followed by eyelid with conjunctiva (3), and conjunctiva alone (4). All patients presented with the clinical suspicion of malignancy. \u0000Histologically, 11 invasive PSC (55%) exhibited poorly differentiated morphology, composed of predominantly atypical basaloid cells with minimal sebocytic differentiation; 9 cases (45%) were moderately-differentiated with noticeable finely multivacuolated cytoplasm; and 3 (15%) showed associated comedo-necrosis. Most invasive PSC showed moderate to brisk mitotic activities. \u0000Of those cases with available immunostains (n=31), 25 (80.6%) expressed adipophilin; 18 (58.1%) Ber-EP4; 14 (45.2%) epithelial membrane antigen (EMA); and 5 (16.1%) both androgen receptor and perforin positivity. PRAME expression was seen in normal sebaceous glands; however, only (5/19; 26%) of invasive PSC showed focal weak-to-moderate PRAME positivity, and mostly in moderately-differentiated tumors. None of the in-situ PSC were PRAME positive. \u0000\u0000Conclusions: Most PSC are moderate- to poorly-differentiated. Although PRAME is expressed in normal sebaceous units, it appears less useful as diagnostic marker for PSC, especially in poorly-differentiated tumors. In difficult cases, panels of immunohistochemical studies (Adipophilin, Ber-EP4 and EMA) achieve a definitive diagnosis.","PeriodicalId":19434,"journal":{"name":"Ocular Oncology and Pathology","volume":"128 ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138982228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Population-based retrospective cohort study of all Olmsted County, Minnesota residents with any ocular neoplasm-related ICD-9 code from January 1, 2006 to October 1, 2015. All medical records were reviewed for confirmation of ocular neoplasm. Diagnoses with ≥5 cases confirmed via medical record review were compared to corresponding ICD-9 codes. Main outcome measures included positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of ICD-9 codes. Results: Among 3,932 subjects with ≥1 ocular neoplasm-related ICD-9 code, 21 diagnoses met study criteria. The most frequent intraocular, extraocular/orbital, and ocular surface diagnoses were choroidal nevus (n=824), epidermal inclusion cyst (n=263), and conjunctival nevus (n=74), respectively.

Because its diagnosis requires clinical-pathologic correlation, the true incidence of SO is unknown, and there is a need to understand the recent trends in risk factors and frequency of this condition. Methods: Pathology records of all enucleated or eviscerated (ENEV) eyes at three pathology laboratories were reviewed. Data collected included patient demographics, procedure indication, pathology diagnosis, and clinical history of trauma and uveitis. IRIS® Registry (Intelligent Research in Sight) was searched for all patients with SO, acquired absence of eye (AAE), and/or ENEV. Data obtained included patient demographics, ocular procedures, and preoperative diagnoses within 30 days of AAE/ENEV. Results: In the pathology laboratory setting, the incidence of SO over a 36-year period in patients who underwent ENEV was 0.2% (20/9,092); the 5-year incidence ranged from 0.0-0.3%. Among the 20 eyes with SO, the inciting event was surgical trauma in 50% (10/20), non-surgical trauma in 45% (9/20), and missing/undetermined in 5% (1/20). SO was suspected pre-operatively in 7/20 (35%) patients. Clinical concern for SO and ruptured globe were indications for ENEV in 50/9,092 (0.5%) and 872/9,092 (10%) patients, respectively. In the IRIS Registry, 0.7% (199/27,830) of patients with AAE/ENEV had diagnosis of SO. The frequency of SO between 2015-2020 was 0.01% (7,371/62,318,249); of these 7,371 cases, 199 (3%) had AAE/ENEV. In 25,975 patients with available data, injury and SO were listed as diagnoses less than 30 days prior to AAE/ENEV in 909 (4%) and 63 (0.2%) cases, respectively.
