Key result
Surgical resection of a rare cardiac composite haemangioendothelioma in a 59-year-old female resulted in a favourable outcome with no signs of local relapse or metastasis at two years.
Why the study?
Composite haemangioendothelioma is an extremely uncommon cardiac tumour that has only been reported twice in the heart.
Case Report (n=1)
Composite haemangioendothelioma is a rare cardiac tumor that can be successfully managed with surgical resection alone, showing no recurrence at two years.
Supports resection alone for this rare tumor; leaves open need for longer follow-up and larger series.
Background: Primary cardiac neoplasm is rare and generally benign. Epithelioid haemangioendothelioma, a potentially malignant tumour of vascular origin, has been occasionally described in the heart. Composite haemangioendothelioma, characterized by a heterogeneous architecture of vascular components and usually located in soft tissue of the extremities, has only been reported twice in the heart. We herein report another case of this extremely uncommon cardiac tumour. Case summary: Comprehensive cardiac examination of a 59-year-old female patient with palpitations and personal history of Hodgkin's lymphoma and chest radiation revealed a mass in the left atrium. After surgical resection, histopathological and immunohistochemical analysis identified a composite haemangioendothelioma. After two years, repeated imaging revealed neither signs of local relapse nor metastasis. Conclusions: Composite haemangioendothelioma, a very uncommon form of potentially malignant vascular tumour, can also be encountered in the heart. In this present case, the outcome was favourable two years after surgical resection without adjuvant therapy.

Schaeffer et al. (2023) conducted a case report in Composite haemangioendothelioma in the heart (n=1). Surgical resection was evaluated on local relapse or metastasis. Surgical resection of a rare cardiac composite haemangioendothelioma in a 59-year-old female resulted in a favourable outcome with no signs of local relapse or metastasis at two years.
