Secondary sternal cancer typically arises when cancer spreads either through the bloodstream from other sites or directly from neighboring lung or breast cancers.  \nPain is the primary symptom, but these metastases can lead to skeletal-related events such as pathological fractures, hypercalcemia, and spinal cord or nerve compression, necessitating surgical or radiotherapy interventions. These events contribute to increased morbidity and costs for both patients and the healthcare system.  \nWe report the case of a 63-year-old female patient who presented with a sternal mass and whose further investigations revealed metastatic lung cancer in the sternum.  \nCategories: Cardiac/Thoracic/Vascular Surgery, Allergy/Immunology, Pulmonology  \nKeywords: sternal mass, squamous cell carcinoma, sternal biopsy, sternum metastasis, lung cancer  \nIntroduction  \nLung cancer is the second most common cancer, taking approximately 130,000 people 's lives each year. Oneof lung cancer 's challenges is that symptoms might be minor or nonexistent, resulting in many cases being discovered at an advanced stage of the disease. Metastasis in the chest bones may occur through two basic  \nroutes: hematogenous or lymphogenous [1] .  \nPrimary sternal tumors are uncommon, accounting for only 0.6% to 1% of all tumors. Furthermore, the vast majority of these sternal tumors are malignant [2] .  \nBreast, lung, kidney, and thyroid cancers are common causes of sternal metastasis. Lymphoma,  \nbronchogenic carcinoma, breast cancer, and pleural or mediastinal malignancies are all known to cause  \ndirect sternal invasion [3] .  \nWe present a case of sternal metastasis in lung cancer and a review of the literature.  \nCase Presentation  \nA 63-year-old man who had been a habitual smoker for six months arrived with many symptoms. A chronic dry cough, chest discomfort, dyspnea, and the presence of a tiny lump on the sternum were among the  \nsymptoms. These symptoms developed in the context of anorexia and weight loss.  \nA thoracic computed tomography (computed tomography) scan revealed an excavated lung mass in the right lingular region alongside an osteolytic lesion on the sternal manubrium. A fibroaspiration was performed to look for acid-alcohol-resistant bacillus [PRP1] [H2], and the results came back positive. Consequently, the  \npatient was prescribed antituberculosis treatment.  \nThe patient was referred to our department for further management due to the patient 's deteriorating health and a noticeable increase in the sternal mass size.  \nDuring the general examination, the patient had pallor and asthenia; the vital signs recorded were as follows: a temperature of 37.8 °C, breathing rate of 20 cycles per minute, pulse rate of 100 beats per minute, and blood pressure of 100/70 mmHg.  \nDuri","cbCaiuZXdw23g5mo","https://ap.wps.com/l/cbCaiuZXdw23g5mo","pdf",697524,"English","# Abstract\n# Introduction\n# Case Presentation\n## Symptoms and initial findings\n## Imaging and diagnostic workup\n## Biopsy and pathology\n# How to cite this article","[{\"question\":\"Why is sternal metastasis from lung cancer clinically significant?\",\"answer\":\"It commonly presents with pain and can lead to skeletal-related events such as pathological fractures, hypercalcemia, and spinal cord or nerve compression, often requiring surgical or radiotherapy interventions.\"},{\"question\":\"How did the patient present in the case report?\",\"answer\":\"The report describes a 63-year-old female with a sternal mass; further investigations identified metastatic lung cancer involving the sternum.\"},{\"question\":\"What are the two main routes for chest-bone metastasis mentioned in the introduction?\",\"answer\":\"Metastasis in chest bones may occur through hematogenous (bloodstream) or lymphogenous (lymphatic) routes.\"}]","Sternal Metastasis of Lung Cancer - A Case Report and a Review of the Literature | PDF",1789995409,15]
