Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor of intermediate malignancy with tendency for local invasion and recurrence. The tumor almost exclusively occurs in children, especially in infants. Intracranial KHE are extremely rare with only two cases reported in the literature.
We report the clinical and pathological features of this rare tumor arising from basitemporal region in a 21-month child. Our case did not present with Kasabach-Merritt phenomenon. Histopathological examination confirmed the diagnosis of KHE.
KHE should be considered in the differential diagnosis of intracranial extra-axial neoplasm in children, and histopathological examination plays an important role in distinguishing KHE from its morphologic mimics. It is essential to diagnose KHE due to its locally aggressive nature.
卡波西样血管内皮细胞瘤(KHE)是一种罕见的具有局部侵袭和复发倾向的中度恶性血管肿瘤。该肿瘤几乎仅发生于儿童,特别是婴儿。颅内 KHE 极为罕见,文献中仅报告过两例。
我们报告了一例罕见的发生于 21 月龄儿童颞底的肿瘤的临床和病理学特征。我们的病例未出现卡-梅现象。组织病理学检查证实了 KHE 的诊断。
在儿童颅内轴外肿瘤的鉴别诊断中应考虑 KHE,组织病理学检查对于将 KHE 与其形态学类似物区分开来具有重要作用。由于其具有局部侵袭性,因此诊断 KHE 至关重要。
