However, the role of delayed lymphatic mapping following prior WLE remains unclear. We report the case of a patient who underwent lymphoscintigraphy before and after WLE for melanoma, compare the findings, and review the published literature. A 32-year-old woman was scheduled for WLE and SLNB of a 2.0-mm Breslow thickness melanoma on the upper arm. After her preoperative lymphoscintigram, an unplanned pregnancy was diagnosed, and she elected to proceed with WLE alone. She later requested delayed SLNB and underwent a second lymphoscintigram 2 months later. Comparison of the pre- and post-WLE lymphoscintigrams demonstrated variation in the location and number of sentinel lymph nodes, raising important questions about the accuracy of delayed lymphatic mapping and SLNB in melanoma. This report adds to the understanding of lymphatic channel behavior following WLE and may help inform decision-making for patients and clinicians.","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148162535","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}

We report the case of a 73-year-old man with a persistent, painful lesion on the vertex and parietal scalp that failed to respond to multiple courses of antibiotics and topical therapies for presumed infectious and inflammatory dermatoses. Examination revealed crusted erosions and plaques with a nodular component, initially mimicking chronic inflammatory skin disease or a potentially neoplastic entity. Histopathologic evaluation of a punch biopsy demonstrated sheets of atypical epithelioid cells with marked nuclear pleomorphism and frequent mitoses. Immunohistochemical staining confirmed endothelial origin with diffuse positivity for ERG and CD31, while excluding squamous, melanocytic, lymphoid, and epithelial neoplasms. These findings established the diagnosis of EA. The patient was referred for oncology evaluation and initiated on radiation therapy. Cutaneous EA most commonly affects elderly White men and arises on the scalp or face. Prognosis remains poor, with 5-year survival rates below 15% because of high recurrence and early metastatic potential. This case underscores the importance of maintaining a high index of suspicion for EA in nonhealing scalp lesions and highlights the central role of histopathology and immunohistochemistry in establishing the diagnosis.","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148162012","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}

Since its initial description, several clinical subtypes have been recognized, including a reactive form associated with chronic inflammatory or neoplastic conditions. We report the case of an 88-year-old man with extensive reactive ESFA developing in the setting of long-standing postthrombotic lymphedema and neglected ulceration. The patient presented with poor general health, bilateral pleural effusions, multiple verrucous nodules, severe stasis ulcers, and secondary polymicrobial and fungal infections. Histopathologic examination of a nodule demonstrated interconnecting cords of cuboidal epithelial cells with ductal structures within a fibrovascular stroma, consistent with eccrine differentiation and diagnostic of ESFA. Management focused on infection control, wound care, and supportive therapy, as surgical excision and amputation were not suitable options. Clinical improvement was achieved; however, ongoing monitoring was advised because of the potential for malignant transformation. This case highlights the role of chronic tissue injury in the pathogenesis of reactive ESFA and underscores the importance of histopathology for diagnosis, multidisciplinary collaboration in management, and individualized treatment planning in elderly patients with advanced comorbidities.","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148162084","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}
