Diffuse miliary haemangiomatosis is a rare condition representing 2.5-3% of cases of cutaneous infantile haemangiomas. It is an efflorescence of five or more infantile cutaneous haemangiomas associated with visceral involvement, most commonly liver involvement. The severity is mainly related to the risk of congestive heart failure. These vascular anomalies are characterised by their clinical, evolutionary and structural polymorphism. The prognosis, whether aesthetic, psychological, functional or vital, is very heterogeneous, which conditions their frequently multidisciplinary management. The objective of this work is to report a complicated form of miliary hemangiomatosis illustrating clinical, radiological and biological particularities.
