"Kaposiform haemangioendotheliomas grossly appear as infiltrating nodules/masses. Sizes vary from small nodules or plaques to massive infiltrating tumours. Lesions often show a purple/red colouration. Intra-thoracic and intra-abdominal lesions tend to be larger and more infiltrative than peripheral lesions 5,6."
"Lesions show a homogeneous mass with ill-defined margins, often with extension into surrounding structures. Unenhanced CT often demonstrates homogeneous masses with iso-attenuation to adjacent muscle and heterogenous enhancement with contrast administration 6,7."
"Lesions are heterogenous, hyperintense masses on T2-weighted images, with heterogeneous enhancement with contrast administration 7."

"The majority of patients present with an enlarging cutaneous mass that may have red/purple cutaneous markings and telangiectasia. Other cutaneous presentations include erythematous plaques, patches or nodules. Non-cutaneous involvement can result in non-specific symptomatology depending on the organs involved 1,2,5."
"Kaposiform haemangioendotheliomas can occur anywhere in the body but have a predilection for the trunk and extremities. They are most commonly present in the subcutaneous tissue and tend to cross tissue planes involving fascia, muscle, bone and other structures 5."
"Immunohistochemistry shows positivity for CD31, CD34 and lymphatic markers such as podoplanin (D2-40), LYVE1 and/or PROX1 3,6."
