Primary cardiac lipoblastoma of the right atrium

Lipoblastoma is a rare neoplasm of the embryonal white fat. It occurs most commonly in children under the age of 3 years and usually inflicts the superficial soft tissues of trunk and extremities. We present the case of a 3-year-old male patient with a successfully resected primary cardiac right-atrial lipoblastoma with COL1A2::PLAG1 gene fusion.

Update of Pediatric Lipomatous Lesions: A Clinicopathological, Immunohistochemical and Molecular Overview

Lipomatous neoplasms are a rare entity in the pediatric population, comprising less than 10% of soft tissue tumors in the first two decades of life. Some characteristics of pediatric adipocytic tumors are analogous to their adult counterparts, some pediatric lipomatous lesions however harbor unique features. In recent years, there have been significant advances in the understanding of the pathogenesis and hence in the classification and treatment of pediatric adipocytic tumors. This literature-based article will provide a review of the presently known clinicopathological, immunohistochemical and molecular features of pediatric lipomatous lesions.

Cardiac lipoblastoma of the pulmonary valve: A rare tumor in an unusual location

BACKGROUD

Lipoblastoma is a rare, benign, fatty tissue tumour tumor that occurs in infancy and early childhood. Intrathoracic and mediastinal involvement of this tumour is rare, and an intracardiac location is even rarer.

AIMS

To report the first case of a lipoblastoma in the pulmonary valve.

MATERIALS

In this study, we report the case of a 15-month-old girl who presented with a tumour in the pulmonary valve.

RESULTS

The tumour was completely resected macroscopically. Histological examination of the lesion confirmed the diagnosis of lipoblastoma.

DISCUSSION

Most primary cardiac tumours are benign in the sense they are not invasive. However, benign tumours maintain the potential for serious illness related to significant haemodynamic compromise or life-threatening dysrhythmias. Due to the association of lipoblastoma with other heart malformations, preoperative diagnosis remains challenging.

CONCLUSION

Tumours on the heart valve are more likely to cause haemodynamic disturbances. Complete resection yields an excellent prognosis.

Lipoblastoma of the left kidney: a case report and review of literature

A lipoblastoma is an infrequent benign tumor derived from embryonal adipose tissue. There are few reports on kidney lipoblastomas; there are fewer than three cases, including our case. An 80-year-old female was detected to have a left renal mass during a routine medical examination. Computed tomography (CT) and magnetic resonance imaging (MRI) indicated a heterogeneous mass before surgery, and histopathological tests subsequently revealed that the mass was a rare lipoblastoma. We present this case as a reminder to consider lipoblastomas in the differential diagnoses of kidney masses.
