Adult intracardiac rhabdomyoma resembling the extracardiac variant

Cardiac masses : Experience from a Turkish tertiary center of cardiology

OBJECTIVE

Cardiac masses comprise a category that includes benign, malignant, and nontumoral mass lesions. The present study aims to share the findings relating to cardiac masses observed at our tertiary cardiology hospital in Turkey.

METHODS

The records of patients who presented with cardiac masses and underwent surgery at our institute between 2006 and 2015, and whose tissue samples were sent to a pathology laboratory, were retrospectively reviewed in a consecutive manner.

RESULTS

The study included 228 patients with an average age of 52.5 ± 17.3 years. Of the study's subjects, 95 (41.7%) were male and 133 (58.3%) female. The most commonly observed mass was myxoma in 68 patients (29.8%), of whom 20 (29.4%) were male and 48 (70.6%) female. The second most frequently detected mass was pannus, with 38 cases (16.7%) - 10 (26.3%) in males and 28 (73.7%) in females. The third most common cardiac mass was thrombus (16.2%), with 18 cases of thrombi in men (48.6%) and 19 (51.4%) in women.

CONCLUSION

The most commonly observed cardiac mass was myxoma and most were localized in the left atrium. The second most frequently detected mass was pannus, which was mostly found on mitral mechanical prosthetic valves. Thrombi were the third most prevalent mass and were commonly localized in the right atrium.

Cardiac rhabdomyoma in an adult patient presenting with right ventricular outflow tract obstruction

We present a 24 year old woman with cardiac rhabdomyoma. Cardiac rhabdomyoma is the most common benign cardiac tumor in infants, but in adults, cardiac rhabdomyoma is very rare. These tumors are often spontaneously reversible because they are associated to the right or left ventricular outflow tract obstruction, tachyarrhythmias and heart failure where surgery is necessary.

Multifocal adult rhabdomyoma: a case report and literature review

Adult extracardiac rhabdomyoma is an uncommon primary tumor of striated muscle origin that almost exclusively presents in the head and neck region. The occurrence of multifocality is a rare manifestation of this unusual lesion. In this study, we report a rare case of multifocal adult extracardiac rhabdomyoma in a patient presenting with an asymptomatic neck mass and provide a brief review of the literature on this entity.

Multifocal adult rhabdomyoma of the head and neck: a case report and literature review

Adult extracardiac rhabdomyomas are rare benign skeletal muscle tumors that most commonly present in the head and neck region. Only a few multifocal cases have been described to date in the world literature. We hereby present an additional multifocal case, the 14th worldwide, and review the literature.

Adult cellular rhabdomyoma of the heart: a report of 3 cases

We present 3 adults with cardiac rhabdomyomas, 2 in the atria and 1 in the right ventricle. One atrial tumor was discovered incidentally, and 1 resulted in supraventricular tachycardia. The ventricular lesion caused ventricular tachycardia. Compared with congenital rhabdomyomas, the tumors are relatively cellular, the cells are smaller, there are few spider cells, and there is evidence of cell proliferation. Two of the 3 tumors demonstrated spindling in contrast to adult rhabdomyomas of the head and neck. Although surgical excision was possible in all patients, long-term follow-up will be required to determine the true biologic behavior of these neoplasms.

Cardiac rhabdomyoma in an adult patient presenting with ventricular arrhythmia

Cardiac rhabdomyomas are extremely uncommon in the adult patient. We describe a previously healthy man who presented with ventricular arrhythmias resulting from a right ventricular, cardiac rhabdomyoma. Echocardiography, CT scanning, and MRI are recognized as useful diagnostic modalities for intracardiac lesions. Cardiac catheterization in our patient demonstrated the presence of a tumor blush. This has not previously been reported with cardiac rhabdomyomas. Although lesions may spontaneously regress, surgery is often necessary and frequently resolves the underlying arrhythmia.

Oesophageal rhabdomyoma

Extracardiac rhabdomyomas are rare benign tumours showing striated muscle differentiation. Seventy percent of these lesions occur in the head and neck region. The most common sites for these lesions are the larynx, pharynx, and the floor of the mouth. There has been only one previous report of a rhabdomyoma of the oesophagus; two further cases are described.
