Paraneoplastic syndromes rarely manifest as orbital inflammation, and only a few cases have been described in association with solid tumors. We present a case of a 67-year-old male diagnosed with esophageal cancer. Shortly after diagnosis, he developed rapidly progressive bilateral exophthalmos with ophthalmoplegia. Thyroid function and thyroid-stimulating immunoglobulin were normal, and MRI orbits demonstrated enlargement of extraocular muscles with apical crowding, consistent with inflammatory orbitopathy. Given the absence of thyroid disease, a paraneoplastic process was suspected. The patient was treated with prednisone 60 mg daily, tapered over 5 weeks, resulting in complete resolution of symptoms within 2 weeks. He underwent chemoradiation with interval improvement in the primary tumor. Several months later, disease progression occurred with new mediastinal and iliac lymphadenopathy, coinciding with recurrence of exophthalmos. A second course of corticosteroids again resulted in full remission of the orbital findings. This case highlights paraneoplastic exophthalmos as a rare manifestation of esophageal adenocarcinoma. The temporal association between tumor activity and orbital inflammation, coupled with steroid responsiveness, supports an immune-mediated mechanism. Recognition of this phenomenon is important to avoid misdiagnosis and to guide prompt corticosteroid therapy and oncologic management. In summary, exophthalmos is a very rare paraneoplastic finding. Workup needs to include brain imaging to exclude direct metastasis to the retro-orbital space. Immediate treatment for neoplastic disease is likely to resolve symptoms. High-dose steroids are effective in relieving symptoms.</p>","PeriodicalId":9636,"journal":{"name":"Case Reports in Oncological Medicine","volume":"2026 ","pages":"5230454"},"PeriodicalIF":0.6,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13147345/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147834205","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}

However, in oncologic settings, delaying surgery may result in irreversible loss of resectability and adverse outcomes. Evidence guiding surgical decision-making in patients with advanced cancer and severe endocrine dysfunction remains limited. We report the case of a patient with triple-negative breast cancer initially staged as IIA who discontinued neoadjuvant chemotherapy and subsequently developed rapid locoregional progression to stage IIIB. Despite reinduction with chemotherapy and immunotherapy, the tumor remained refractory, and rescue mastectomy was indicated as the only remaining oncologic option. Preoperative assessment unexpectedly revealed severe biochemical hypothyroidism with markedly elevated thyroid-stimulating hormone levels and reduced free thyroxine, raising concern for perioperative metabolic decompensation and myxedema coma. Given the risk of permanent loss of operability associated with surgical delay and the prolonged time required to achieve full biochemical euthyroidism, a multidisciplinary decision was made to proceed with surgery after partial endocrine optimization using oral levothyroxine. Following extensive informed consent and anesthetic planning, rescue mastectomy with wide elliptical skin excision was performed without intraoperative or postoperative complications. The patient had an uneventful recovery, with negative surgical margins and no need for postoperative ventilatory support. This case highlights the challenges of managing severe biochemical hypothyroidism in time-sensitive oncologic surgery. When surgery represents the only viable therapeutic option, individualized multidisciplinary decision-making and shared risk assessment may justify proceeding despite incomplete metabolic optimization. Rescue surgery may be considered in carefully selected high-risk patients when the oncologic benefit outweighs the potential perioperative risk.</p>","PeriodicalId":9636,"journal":{"name":"Case Reports in Oncological Medicine","volume":"2026 ","pages":"3822467"},"PeriodicalIF":0.6,"publicationDate":"2026-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13092926/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147763468","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}
