Composite hemangioendothelioma comprises permutations of different histological patterns few of which have been found to have specific genetic alteration and immunohistochemical expression. It comprises retiform or epithelioid hemangioendothelioma-like areas, with a variable proportion of hemangioma or low-grade angiosarcoma-like areas. It was found to express neuroendocrine markers and was seen to have a worse prognosis in recurrence or distant metastasis. A 29-year-old woman presented with a lesion of 22 cm in size in her right leg. Biopsy and wide local excision showed features of composite hemangioendothelioma. This is a recurrent lesion after initial resection 2 years back, along with a cutaneous metastasis in the thigh. We report this rare case with a literature review, highlighting the importance of uncommon histomorphology and neuroendocrine marker expression in predicting local recurrence and cutaneous metastasis.

Introduction And Aim: Propranolol is an effective treatment option for infantile hemangiomas, but there is still insufficient information about neurodevelopmental side effects of propranolol. In our study, the neurodevelopmental levels of infantile hemangioma patients receiving propranolol treatment were examined using the Bayley-III test.
Method: In our single-center, cross-sectional study, patients were recruited between 1 January 2020 and 31 December 2023.

Article Synopsis
- Primary benign cardiac tumors in children are rare but can lead to serious complications like malignant ventricular arrhythmias and cardiac death.
- A study conducted over 38 years included 97 children with various types of tumors, revealing that those with tumors larger than 2.3 cm or diagnosed with fibromas had worse health outcomes.
- The research highlighted that 24.5% of the patients experienced clinically significant arrhythmias, suggesting that tumor type and size are important indicators of potential risks.
