The sternum is a rare site of Hodgkin’s lymphoma, which is often misdiagnosed as tuberculosis on routine histopathology.CASE SUMMARY We reported a 47-year-old female patient with chest pain in the upper sternum for 1 mo. Chest computed tomography found a mass in the upper sternum.Pathology and immunohistochemistry of the biopsy confirmed the diagnosis of typical Hodgkin’s lymphoma(mixed cellularity subtype). Patient was diagnosed with primary sternal Hodgkin’s lymphoma and administered 6 cycles of adriamycin, bleomycin, vinblastine, and dacarbazine chemotherapy. Patient had no tumor recurrence and progression at a follow-up visit 2 years later.CONCLUSION This study highlights the rarity of primary sternal Hodgkin’s lymphoma and the challenges of its diagnosis. A Pub Med and Web of Science search revealed 10 reported cases of sternal involvement in Hodgkin’s lymphoma.展开更多

Most paragangliomas are nonfunctional, therefore, asymptomatic functional paragangliomas in the left posterior mediastinum are extremely rare. Perioperative management including preoperative preparation, careful intraoperative procedures, and strict postoperative care is important, and one-stage surgical resection should be performed only after appropriate perioperative measures are undertaken. Because those tumors are rare, it is necessary to report known cases to raise awareness regarding them. CASE SUMMARY We report the case of a 47-year-old male who was admitted to our hospital with the chief complaints of intermittent tearing pain on the left side of the chest and back for more than 10 mo. A chest contrast-enhanced computed tomography scan revealed a round, solid mass in the left posterior mediastinum, with low-density cystic lesions in the middle, and no enlarged lymph nodes in the hilum or mediastinum (Figure 1). After the diagnosis of paraganglioma, the patient was preoperatively given an oral adrenoceptor blocking drug (phenoxybenzamine), and intravenous fluid resuscitation for two weeks, subsequently the patient underwent a one-stage resection of lesions via left thoracotomy. The patient’s blood pressure increased to 220/120 mmHg when the tumor was touched, which could be relieved by symptomatic treatment such as accelerating liquid transfusion or other intervention to lower blood pressure. The patient recovered uneventfully after surgery, with no abnormal blood pressure or recurrence during one year of follow-up visits.CONCLUSION Surgical resection is the preferred treatment for asymptomatic functional paragangliomas.展开更多
