{"title":"Nonsurgical Management of Cardiac Papillary Fibroelastoma on the Aortic Valve.","authors":"Yonis Hakim, Yousef Raslan Hakim, William Barker, Tariq Ahmad","doi":"10.14740/jmc5247","DOIUrl":"10.14740/jmc5247","url":null,"abstract":"<p><p>Papillary fibroelastomas are benign cardiac tumors that constitute the second most common cardiac tumors. Controversy exists in the management of papillary fibroelastoma. When to surgically manage the patient or use pharmaceutical therapy is not clear. There are studies that indicate that nonsurgical management might be associated with higher mortality and morbidity rates and more adverse events. There has not been a reported case of papillary fibroelastoma managed successfully with only anticoagulation. Clearer guidelines are needed for the management of papillary fibroelastoma, especially in cases where a patient is a poor surgical candidate or declines surgical intervention. In this case, a patient has been managed nonsurgically for 4 years and 7 months up to date. The patient is a 57-year-old female who presented to the emergency department with myocardial infarction symptoms. The myocardial infarction was thought to be secondary to an embolic event after a patent foramen ovale was identified on transthoracic echocardiogram or sequelae from arrhythmia. Cardionet ruled out arrhythmia, and patent foramen ovale closure workup revealed a 0.3-cm mobile papillary fibroelastoma. Surgical management was not pursued due to surgical risks and the patient's preference, and the patient was prescribed long-term apixaban. The patient was followed for 4 years and 7 months and experienced an episode of vaginal bleeding during this time. This case shows an example of when nonsurgical management can be pursued as the patient declined surgical intervention after benefits and risks were discussed. Also, this case shows the importance of considering the patient's bleeding risk, such as this patient's history of hematuria due to acute cystitis, miscarriages, and heparin-induced gingival hematoma while hospitalized, prior to initiating anticoagulation. Bleeding risk can be assessed using the HAS-BLED risk score or equivalent.</p>","PeriodicalId":101328,"journal":{"name":"Journal of medical cases","volume":"17 2","pages":"70-74"},"PeriodicalIF":0.9,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12861516/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146109492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 77-year-old male with long-standing lower urinary tract symptoms and mildly elevated prostate-specific antigen was found to have a large (7.4 cm) predominantly cystic pelvic mass replacing the left seminal vesicle on magnetic resonance imaging. Histologic evaluation revealed synchronous high-grade prostate adenocarcinoma and a distinct dedifferentiated carcinoma not arising from prostatic tissue. Comprehensive immunohistochemical analysis supported a diagnosis of PSVA. The patient underwent robotic-assisted radical prostatectomy with <i>en bloc</i> excision of the seminal vesicle mass, rectal repair, and ureteral reimplantation. Postoperatively, prostate-specific antigen remained undetectable; however, tumor-informed circulating tumor DNA (ctDNA) testing detected molecular residual disease. Following completion of radiotherapy, ctDNA became undetectable, and the patient has remained disease-free at nearly 1 year of follow-up. This case highlights the importance of comprehensive imaging, detailed immunohistochemical profiling, and aggressive multimodal management in PSVA, and represents the first documented report of molecular clearance using ctDNA after treatment for this rare malignancy.

While first-line BEP (bleomycin, etoposide, cisplatin) chemotherapy achieves high cure rates in most patients, those who progress after multiple lines of therapy have a poor prognosis and limited treatment options, highlighting a critical gap in effective treatment decision-making for advanced disease. This previously reported case is an example of precision medicine and also demonstrates that the therapeutic effect is not transient but can be sustained long term, as shown by our 5-year follow-up. This 21-year-old man with widely metastatic NSGCT initially underwent orchiectomy followed by BEP chemotherapy, which achieved only a partial response. He then experienced rapid progression with new lung and brain metastases that were unresponsive to second-line GEMOX (gemcitabine + oxaliplatin) chemotherapy and a programmed death-ligand 1 (PD-L1) blockade clinical trial. When treatment options were exhausted, comprehensive molecular profiling of a new lung lesion identified 22 oncogenic alterations, including Kirsten rat sarcoma viral oncogene (<i>KRAS</i>) amplification. Guided by a molecular tumor board (MTB) recommendation, an off-label regimen of carboplatin, paclitaxel, and sorafenib (CPS) was initiated, targeting the MAPK pathway. The tumor again developed resistance to CPS, prompting a rational BEP rechallenge that resulted in disease stabilization and ultimately a durable long-term remission. At the 5-year follow-up in July 2025, the patient remains disease-free with a normal quality of life. We present this N-of-1 case to illustrate how molecularly guided post-resistance treatment can inform therapeutic decision-making in advanced disease. Tumors are highly complex, and gene-cancer interaction is still being elucidated. In this context, key learning points from this case include: 1) the critical role of iterative molecular profiling and MTB guidance in identifying actionable targets when standard options are exhausted; 2) the potential value of rational drug rechallenge informed by the evolving \"tumor ecology;\" and 3) the necessity of long-term follow-up to link treatment responses with biomarkers, allowing N-of-1 learning that may offer a template for personalized management in similarly challenging cases.</p>","PeriodicalId":101328,"journal":{"name":"Journal of medical cases","volume":"17 2","pages":"54-61"},"PeriodicalIF":0.9,"publicationDate":"2026-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12861522/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146109508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our first case, to facilitate an intraoperative wake-up test, the clinical effects of remimazolam were reversed with flumazenil.
