■恶性间皮瘤(MM)是一种罕见的侵袭性肿瘤,存在于胸膜和腹膜中。已报道了几例心包和阴道膜睾丸中的MM。此外,原发性发生在中庭极为罕见。这种肿瘤的视觉外观与常见的心房粘液瘤相似,这使得临床医生和放射科医生诊断和治疗这种疾病具有挑战性。
一名18岁女性出现胸痛症状,呼吸急促,咳嗽,并咳痰7天。对患者进行了超声心动图检查,显示心房肿块。粘液瘤是鉴别诊断之一。肿瘤是一个有尖端的椭圆形肿块,切割表面像果冻一样,类似于粘液瘤。手术后,活检肿瘤的病理检查证实为上皮型MM。术后随访期间,未观察到肿瘤复发。
■源自中庭的MM被认为极为罕见。因此,临床医生很容易将心房MM误诊为粘液瘤。此外,为了确认诊断,组织病理学活检,组织形态学特征,免疫组织化学,分子基因检测是必需的.因此,MM的临床诊断和治疗具有挑战性。
UNASSIGNED: Malignant mesothelioma (MM) is a rare and aggressive tumor that is found in the pleura and peritoneum. A few cases of MM in the pericardium and tunica vaginalis testis have been reported. Moreover, primary occurrence in the atrium is extremely rare. The visual appearance of this tumor is similar to that of a common atrial myxoma, which makes it challenging for clinicians and radiologists to diagnose and treat this disease.
UNASSIGNED: An 18-year-old woman presented with symptoms of chest pain, shortness of breath, cough, and expectoration for 7 days. Echocardiography was performed on the patient, which revealed an atrial mass. Myxoma was one of the differential diagnoses. The tumor was an elliptical mass with tips, and the cut surface was jelly-like, similar to myxoma. After surgery, a pathologic examination of the biopsied tumor confirmed epithelial-type MM. During postoperative follow-up, no recurrence of the tumor was observed.
UNASSIGNED: MM originating in the atrium is considered to be extremely rare. Consequently, clinicians can easily misdiagnose atrial MM as a myxoma. Moreover, to confirm the diagnosis, histopathologic biopsy, histomorphological characterization, immunohistochemistry, and molecular genetic testing are required. Therefore, clinical diagnosis and treatment of MM are challenging.
