Atrial myxoma

We review the most characteristic clinical and histopathologic findings of the cutaneous manifestations of the occlusive nonvasculitic vasculopathic disorders. Clinically, most of these conditions are characterized by retiform purpura. Histopathologic findings consist of occlusion of the vessel lumina with no vasculitis. Different disorders may produce nonvasculitic occlusive vasculopathy in cutaneous blood and lymphatic vessels, including embolization due to cholesterol and oxalate emboli, cutaneous intravascular metastasis from visceral malignancies, atrial myxomas, intravascular angiosarcoma, intralymphatic histiocytosis, intravascular lymphomas, endocarditis, crystal globulin vasculopathy, hypereosinophilic syndrome, and foreign material...

Atrial myxomas are the most common benign cardiac neoplasms. Although the majority occur in the left atrium (LA) and are attached to the interatrial septum (75-80 % of cases), they can arise from any part of the LA and the cardiac chambers. We report the case of a 65-year-old woman who presented with features of worsening dyspnea and persistent headache. During transthoracic echocardiography, a suspected cardiac myxoma was found arising from the posterior wall of the LA.

Inverted left atrial tissue is mostly identified when the heart is empty while coming off bypass. During echocardiography a new, echodense mobile mass in the left atrium without attachment is visualized. Such a picture can easily produce not only confusion in the diagnosis but also mitral valve obstruction, hemodynamic instability, and a possibility of appendage necrosis. Inability to identify such inverted tissue can lead to unwanted interventions with additional cardiopulmonary bypass time.

Occurrence of left atrial myxoma with severe ventricular dysfunction without any obstructive coronary artery disease, as presented in our case, is very rare. It may be due to undiagnosed concomitant dilated cardiomyopathy or unknown cardiodepressant effect of myxoma which warrants further research.

Right atrial myxomas are rare. Its occurrence in a previously operated patient of rheumatic mitral stenosis posed clinical diagnostic challenge. We herein report a case of right atrial myxoma who had undergone mitral valve repair 20 years ago and now presented in congestive heart failure. The tumor was arising from the ostium of the coronary sinus and prolapsed into the right ventricle causing significant right ventricular inflow and outflow obstruction. Urgent repeat cardiac surgery was successfully performed to remove the tumor along with mitral valve replacement...

Emboli from an atrial myxoma resulted in asymptomatic segmental retinal and choroidal arterial hyperfluorescent lesions on retinal angiography, mimicking an arteritis. The retinal lesions disappeared after removal of the atrial myxoma. Endothelial trauma by embolic material appears to be the mechanism of the angiographic findings.

Atrial myxoma is a rare cardiac tumor that may be diagnosed incidentally on cardiac imaging or may present with life-threatening cardiac symptoms. We present a case of giant left atrial myxoma that presented as a flulike illness.

Cardiac myxoma are the most common benign primary cardiac tumors that can lead to many complications as described in literature. Here we report the case of a boy aged 11 that was referred for etiological diagnosis of ischemic stroke. Transthoracic echocardiography reveals a myxoma in the left atrium. Patient was referred to surgery. The diagnosis was confirmed and the mass was completely resected.

We describe a case of sudden-onset left-sided hemiparesis and dysarthria in a five-year-old boy. Acute vascular malformation bleeding or ischemic stroke was suspected. Neurological examination three weeks after the initial event revealed mild residual facial paresis. Brain angiography ruled out a vascular malformation. A work-up echocardiogram revealed a 4-cm left atrial mass compatible with cardiac myxoma. Urgent surgical resection of the mass under cardiopulmonary bypass confirmed the diagnosis. Uneventful recovery followed surgical resection...

A middle-aged woman with a history of resected colorectal cancer and receiving chemotherapy presented with a right atrial mass and the provisional diagnosis of myxoma supported by echocardiography, computed tomography, and magnetic resonance imaging. Successful surgical removal revealed organized thrombus instead. Atrial thrombus may be mistaken for myxoma and long-term intracardiac indwelling catheters can be thrombogenic.

We report a case of sporadic giant cardiac myxoma with a rare localization in the right atrium, operated in our Service, in a 73-year-old female patient who also presented a patent foramen ovale and a history of ischemic stroke in the year prior to current admission. Intra-operatively, the tumor had a very friable, gelatinous aspect, with a high potential for embolization due to its reduced consistency. The present paper refers to clinical, histochemical and immunohistochemical particularities, as well as to macroscopic and microscopic characteristics of the cardiac myxoma, emphasizing the extracellular matrix aspects, and without leaving out the cellular components of this rare tumor, with possible inference in the management of this disease...

Primary rhabdomyosarcoma (RMS) of the heart is a rare malignant tumor which has poor prognosis and survival despite surgery and adjuvant chemotherapy. The preoperative diagnosis is often difficult in view of nonspecific clinicoradiological findings. This report describes a case of a 60-year-old woman who was clinically diagnosed as left atrial myxoma. A diagnosis of pleomorphic RMS was made on histopathology after excision. Our case discusses the clinicopathological features and treatment options of cardiac RMS emphasizing the fact that histopathology and immunohistochemistry are essential to confirm the diagnosis of such an aggressive malignant tumor...
