Synchronous composite tumors though described are uncommon. Moreover, simultaneous occurrence of synchronous tumors involving the same tissue or organ at multiple sites is even less common. We report a case of acute lymphoblastic leukemia (ALL) and basal cell carcinoma (BCC) occurring simultaneously in multiple skin sites. Several cases showing an association between cutaneous malignancies and lymphoproliferative disorders have been reported. Some of these cases included ALL and BCC and occurred often in the pediatric population with the BCC arising as a post-ALL therapy sequela. Other rare genetic causes may be considered. To our knowledge this is the first time that the synchronous occurrence of these two malignant processes in the same tissue involving multiple sites in an elderly patient is described.
