Familial occurrence of Kaposi's sarcoma. Report of two brothers

The racial and geographical distribution of Kaposi's sarcoma is well recognized. Therefore, a hereditary factor is suspected to play a role in it's etiology. Inspite of this, only about 15 instances of familial cases with the disease have been as yet reported in the literature. We describe here an additional instance of Kaposi's sarcoma occurring in two Jewish brothers born in Rumania and we resume the literature on previous reports of familial occurrence of Kaposi's sarcoma.
