Primary intracardiac leiomyoma: rare case report and literature review.

ABSTRACT

Benign cardiac neoplasms are relatively uncommon. Cardiac leiomyomas are usually diagnosed as a benign metastasizing leiomyoma or as a part of intravenous leiomyomatosis spectrum. Primary cardiac leiomyomas are extremely rare and should be diagnosed after ruling out the involvement of systemic leiomyomas. Only nine cases were found in the literature that described De novo occurrence of primary intra-cardiac leiomyoma. In this study, we present a case of 60-year-old female patient with a large pedunculated mass located in the left ventricle. Histopathology examination and immunohistochemistry aid confirmed the diagnosis of benign leiomyoma. No evidence of extra cardiac lesions was detected in the patient. The patient remained healthy with no signs of recurrence four years after the surgical resection. Benign cardiac tumors are not often seen, but when they do occur, they can present a serious risk to life. This is particularly significant because these tumors can detach and cause embolization, leading to the development of strokes. Moreover, these individuals do not show any clinical symptoms, making their detection quite challenging. When there is a suspicion, it is advised to utilize echocardiography and other imaging techniques to verify the presence of a tumor. In this report, we present a rare case and provide differential diagnoses, along with a review of the literature.
