Multisystem Infantile Hemangiomatosis with Cutaneous, Hepatic, and Splenic Involvement.

backgroundHemangiomatosis is a rare condition characterized by the presence of multiple benign vascular tumors that may affect various organs, including the skin, liver, and spleen. Complications are closely linked to the location and size of the lesions. CASE PRESENTATION: We describe a rare presentation of infantile hemangiomatosis with widespread cutaneous and oral mucosal lesions, further complicated by splenic and hepatic involvement and secondary cholestasis. The initial progression was unfavorable, with an increase in both the number and size of the lesions. Cardiologic evaluation identified minor valvular insufficiencies, but no secondary cardiac failure. Treatment with propranolol and prednisone was initiated, with a slow favorable evolution. There were no new hemangiomas developed, and those on the face and limbs decreased in size, some disappearing entirely. Hepatic and splenic hemangiomas regressed more slowly, but their reduction and the improvement of cholestasis were progressive. Due to significant iatrogenic Cushing's syndrome, prednisone was gradually tapered. Transient subclinical hypothyroidism occurred during treatment, resolving spontaneously.

conclusionsThe present case illustrates the rarity and complexity of multifocal infantile haemangiomatosis and highlights the importance of early diagnosis, comprehensive organ evaluation, and tailored multidisciplinary management. It clearly demonstrates that prompt intervention and careful therapy adjustment can lead to favorable outcomes even in the setting of extensive visceral involvement.
