A pathological, oligosymptomatic fracture associated with epithelioid haemangioendothelioma (EHE), a rare endothelial cell-derived sarcoma, is uncommon. Case Presentation: A 44-year-old patient underwent biopsy procedures three times (2010, 2012, 2013) for a focal lesion of the left ischium, none confirming its malignant nature. The last biopsy revealed a neoplastic tissue with features of discrete dysplasia. The lesion did not undergo medical follow-up for seven consecutive years. In August 2020, the patient presented with right lower limb pain. A CT scan, PET\/CT scan, and biopsy confirmed EHE with spindle\/sarcomatous features. In November 2020, chemotherapy (5xADIC) started (PET\/CT confirmed a partial response). After its completion in July 2021, bone progression occurred and sirolimus-based therapy was started. After 3 months, a small liver metastasis was visualized on PET\/CT, which did not result in the termination of treatment. In December 2021, pamidronate-based antiresorptive therapy was started. Liver metastasis remained stable in follow-up CT scans. Due to pelvic and spinal lesions, the patient was assisted by elbow crutches and underwent radiotherapy, remaining professionally active. The patient did not report any trauma, but in August 2023, a subsequent CT scan revealed a subcapital fracture of the left femoral neck in the fusion phase. Due to pelvic changes and the stable nature of the fracture, surgical treatment was abandoned. Conclusions: An oligosymptomatic femoral neck fracture, not requiring medical intervention is considered a rare complication of bone cancer.<\/jats:p>","DOI":"10.3390\/reports7040111","type":"journal-article","created":{"date-parts":[[2024,12,9]],"date-time":"2024-12-09T04:01:37Z","timestamp":1733716897000},"page":"111","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Subcapital Femoral Neck Fracture in a Professionally Active Patient Undergoing Palliative Treatment for Endothelial Cell-Derived Epithelioid Haemangioendothelioma (EHE)"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-5774-1758","authenticated-orcid":false,"given":"Paulina","family":"Kluszczyk","sequence":"first","affiliation":[{"name":"Student Scientific Society, Department of Internal Medicine and Oncological Chemotherapy, Faculty of Medical Sciences in Katowice, Medical University of Silesia, 40-029 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aleksandra","family":"Tobiasz","sequence":"additional","affiliation":[{"name":"Student Scientific Society, Department of Internal Medicine and Oncological Chemotherapy, Faculty of Medical Sciences in Katowice, Medical University of Silesia, 40-029 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dawid","family":"Szumilas","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Oncological Chemotherapy, Faculty of Medical Sciences in Katowice, Medical University of Silesia, 40-029 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3175-5660","authenticated-orcid":false,"given":"Mateusz","family":"Winder","sequence":"additional","affiliation":[{"name":"Department of Radiology and Nuclear Medicine, Faculty of Medical Sciences in Katowice, Medical University of Silesia, 40-752 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacek","family":"Paj\u0105k","sequence":"additional","affiliation":[{"name":"Department of Pathomorphology, Faculty of Medical Sciences in Katowice, Medical University of Silesia in Katowice, 40-027 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Kwiatkowski","sequence":"additional","affiliation":[{"name":"Radiotherapy Department, Katowice Oncology Center, 40-074 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6367-7794","authenticated-orcid":false,"given":"Jerzy","family":"Chudek","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Oncological Chemotherapy, Faculty of Medical Sciences in Katowice, Medical University of Silesia, 40-029 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,9]]},"reference":[{"key":"ref_1","first-page":"272","article-title":"Risk factors for femoral neck fracture in elderly population","volume":"46","author":"Liu","year":"2021","journal-title":"Zhong Nan Da Xue Xue Bao.
