Kaposiform Hemangioendothelioma (KHE) is a rare, locally aggressive vascular tumor that primarily affects infants and young children. Unlike common hemangiomas, KHE is known for its association with Kasabach-Merritt phenomenon (KMP), a life-threatening condition characterized by thrombocytopenia and coagulopathy.

Juvenile Metachromatic Leukodystrophy (MLD) is a rare, inherited neurological disorder that affects the central and peripheral nervous systems. It is characterized by the accumulation of sulfatides due to a deficiency in the enzyme arylsulfatase A (ARSA), leading to progressive demyelination and severe neurological deterioration. What Is Juvenile Metachromatic Leukodystrophy? MLD is classified into three main
Juvenile Idiopathic Arthritis (JIA) is the most prevalent form of arthritis in children under 16, causing persistent joint inflammation, pain, stiffness, and potential joint damage.
