Peripheral primitive neuroectodermal tumor (pPNET) is a highly aggressive small round cell tumor belonging to PNET/Ewing sarcoma family. Ovarian tumors composed of primitive neuroectodermal elements are extremely rare. Herein we reported two cases of peripheral primitive neuroectodermal tumors of ovary in two patients with different clinical presentations. Definite diagnoses were made bas...

Background: Understanding the differences in genetics of malignancies is crucial for therapeutic decisions. This systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. Material and Methods: We performed a systematic review of the literature published on genetics of pediatrics bone tumors, using PubMed, Google scholar,...

This chapter will cover basic cardiac anatomy and tumors that are commonly found in the heart. The heart is divided into four chambers: left atrium, right atrium, left ventricle, and right ventricle. Different cardiac chambers have a propensity to have different cardiac masses or tumors. Cardiac tumors are rare entities: metastasis to the heart from another primary cancer is 30 times more likel...

multiple primary tumors in a single patient are relatively rare when four or more distinct lesions are considered. herein, we report a case of woman with four different primary tumors: meningioma, renal angiomyolipoma, spinal ependymoma and high-grade soft tissue sarcoma. there was no family history and hereditary syndrome. the genetic analysis was completely normal. to best of our knowledge, t...

Primary cardiac sarcoma is a rare disease in adults. It is also associated with poor prognoses, due to diagnostic delay, therapeutic difficulty, and high metastatic potential. The coincidence of pregnancy and a primary cardiac intimal sarcoma is extremely rare. We report a pregnant woman at 27(+5) weeks gestation who was admitted to the hospital with acute-onset dyspnea. A mass was found on the...

Introduction/Background Uterine sarcomas are rare tumors, representing 3 to 5% of malignant tumors the uterus. They characterized by a significant histopathological and clinical diversity. Their diagnosis is not very often made until analysis hysterectomy or myomectomy specimen, distinguishing between: carcinosarcoma; leiomyosarcoma; rhabdomyosarcoma; adenosarcoma; stromal sarcoma; und...

The management and treatment of the tumors depends mainly upon the size of the tumor, its location and extent of metastasis. If symptoms begin to appear it means that most likely the tumor has spread to such an extent that treatment is going to be highly challenging. An open heart surgical excision of the tumor can be done if the tumor is localized. In cases where excision cannot be done due to...
