Dermoscopy of kaposiform hemangioendothelioma: a case report.

Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor of infancy, characterized by an infiltrative, firm, and ill-defined plaque that may be associated with Kasabach-Merritt phenomenon. While the diagnosis is primarily clinical and histopathological, dermoscopy may provide valuable insights into its microstructural features. We present the case of a newborn with congenital KHE involving the lumbar and right gluteal region, focusing on its dermoscopic characteristics. The lesion exhibited a homogeneous, grayish-blue background with no discernible vascular structures, a feature that may aid in differentiating KHE from other vascular tumors. The findings contribute to the understanding of dermoscopic patterns in KHE, highlighting its potential role in early diagnosis.
