We describe a case of an eyelid cutaneous myxoma with multiple recurrences in an 8-year-old child. The lesion once previously diagnosed as eccrine hidrocystoma had been excised three times with subsequent recurrence. Frozen section diagnosis performed during the fourth excision showed striking basaloid features, prompting deferral of definitive diagnosis to permanent sections. Following routine processing, basaloid proliferations were again seen without significant atypia or mitotic activity in addition to background features of myxoma. CD10 immunostain highlighted both basaloid nests and surrounding stroma. Cutaneous myxoma was diagnosed. The diagnosis was corroborated by an external consultation. The patient underwent genetic testing for the Carney complex with negative results. This case report raises some practical points. First, due to their rarity in the pediatric population and potential to mimic other entities, cutaneous myxomas can be misdiagnosed as other benign neoplasms. Second, although induction of basaloid proliferation has been well-documented in myxoma, it can be easily misinterpreted as a malignant process, particularly in the setting of a frozen section diagnosis and lack of available clinical information. Third, even though solitary cutaneous myxomas are less likely to be associated with the Carney complex, a possibility of such an association should always be born in mind, as consequences of missing syndromic neoplasms, such as cardiac myxoma, can be lethal.","PeriodicalId":50967,"journal":{"name":"American Journal of Dermatopathology","volume":" ","pages":"477-480"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a scarcity of data from nonbiased studies on PLA performance in the real world. PLA results from 107 skin specimens were compared with final pathologic diagnoses. To determine clinical relevance of PLA results, diagnoses were categorized into actionable melanocytic, nonactionable melanocytic, and nonmelanocytic. Of specimens with positive PLA results, 24.0% (25/104) were actionable melanocytic diagnoses, 42.3% (44/104) nonactionable melanocytic, and 33.7% (35/104) nonmelanocytic. Because most specimens submitted for pathologic evaluation had positive PLA results, positive predictive values were calculated for overall PLA results and the individual genes tested. The overall positive predictive value for surgically actionable melanocytic lesions was 24.0%. The positive predictive values of the individual genes were determined to be 28.2% for LINC00518, 34.7% for PReferentially expressed Antigen in Melanoma, and 31.8% for telomerase reverse transcriptase.","PeriodicalId":50967,"journal":{"name":"American Journal of Dermatopathology","volume":" ","pages":"468-471"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144056545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cutaneous T-cell lymphoma (CTCL) predisposes patients to malignancies because of immune dysregulation, and treatments such as narrow-band ultraviolet-B phototherapy increase carcinogenic risk. We describe a 78-year-old man with stage IVA1 CTCL who presented with a scaly, painful tumor on his left temple. Biopsy revealed well-differentiated SCC with atypical lymphoid infiltrate consistent with MF, marked by immunohistochemical positivity for CD3, CD5, CD30, and a CD4:CD8 ratio of 50:1. Mohs surgery was performed, and histopathology analysis confirmed the coexistence of SCC and MF, with greater loss of CD7 expression in atypical lymphocytes. Concurrent SCC and MF demonstrate the need for vigilant surveillance for secondary cutaneous malignancies in patients with advanced CTCL. The case presented herein contributes to expand the reported literature and highlights the necessity of individualized management strategies optimized on an individual's Fitzpatrick skin type and unique risk factors.","PeriodicalId":50967,"journal":{"name":"American Journal of Dermatopathology","volume":" ","pages":"472-476"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144065225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The search for reliable diagnostic markers, including PRAME, holds potential to significantly improve the accuracy of differential diagnoses.Methods: A retrospective analysis of 32 BIMTs from 25 patients, collected between 2018 and 2022, involved histologic examination and immunostaining for BAP-1 and PRAME.Results: Positive PRAME expression, defined as diffuse staining in at least 75% of nevic cells, was observed in 19% of cases. Variations in PRAME expression patterns were noted, particularly in biphasic lesions and those associated with germline BAP-1 mutations.Conclusions: The diagnostic complexities of BIMTs necessitate a comprehensive diagnostic strategy. While BAP-1 immunostaining remains pivotal, this study explored PRAME as a potential adjunctive diagnostic tool. PRAME antibody shows highly variable expression in BIMTs, limiting its utility as a supportive tool for the differential diagnosis with melanomas, especially in patients with biphasic lesions and germline mutations in BAP-1.","PeriodicalId":50967,"journal":{"name":"American Journal of Dermatopathology","volume":"47 6","pages":"421-427"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144095318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
