[Kaposi's sarcoma associated with chronic B lymphocytic leukemia. Coexistence of both diseases in skin lesions].
Kaposi's sarcoma is a rare malignancy. Its association with second primary cancers, especially of the lymphoreticular system, has been relatively frequently noted. We report a case of Kaposi's sarcoma (SK) in a 62 years-old women, affected by B-cell chronic lymphocytic leukemia (LLC B) for 22 month, that had received chemotherapy. Two skin lesions were seen on left lower limb. A biopsy revealed the coexistence of both diseases in the skin lesions. This finding is extremely rare. We review the possible etiopathogenic implications of this association and of the coexistence of both diseases in the same lesion.
