Coexistence of cystic intra-abdominal lymphangiomas and diffuse venous haemangiomas in adult life.

Diffuse haemangioma and intra-abdominal lymphangioma are rare in adults. In this case report, we present a 33-year-old female with coexisting multiple cutaneous and visceral cavernous haemangiomas and two huge intra-abdominal lymphangiomas of 25 and 35 cm in diameter. The organs involved were the liver, pericardium, renal hilus and bladder. She died due to disseminated intravascular coagulation and multiorgan failure, which resembled Kasabach-Merritt syndrome. The coexistence of generalised haemangiomas and intra-abdominal lymphangiomas and the lack of complaints until the age of 33 years makes her an unusual case in the literature. We also emphasise the other clinical conditions that should be considered in the differential diagnosis.
