Angiosarcoma in a 3-year-old child with congenital lymphedema

ABSTRACT

Angiosarcoma occurring in chronic lymphedema has been described in more than 200 cases, especially in the upper extremity following radical mastectomy (Stewart-Treves syndrome). However, angiosarcoma developing in congenital lymphedema is quite rare and the literature presents only 14 cases. Our patient is a girl with congenital lymphedema of the left lower limb that developed an angiosarcoma at 3 years of age, noted initially as a painful nodular lesion on the left thigh. This seems to be the earliest presentation of angiosarcoma associated with lymphedema. It claims attention to a careful evaluation of any lesions in a child with lymphedema to provide a better prognosis, which is allowed by precocious diagnosis and rapid interventions.
