Far from luck’s way: A concurrence of Kaposi sarcoma and cutaneous angiosarcoma in the setting of chronic lymphocytic leukemia

Abstract

Kaposi sarcoma and cutaneous angiosarcoma are rare forms of skin malignancies that are vascular in nature and are frequently encountered in the immunosuppressed population. Although synchronous angiosarcoma and Kaposi sarcoma have been documented, to our knowledge, the coexistence of these vascular malignancies with underlying chronic lymphocytic leukemia has not been previously reported. A 51-year-old male patient with chronic lymphocytic leukemia presented with Kaposi sarcoma located on his left ankle. Shortly after, the patient presented with de novo lesions located on the plantar region of the right foot, reported as angiosarcoma. Following a multidisciplinary decision, treatment with adjuvant chemotherapy consisting of paclitaxel and carboplatin with consolidation radiotherapy was planned. The patient’s Kaposi sarcoma has remained unchanged throughout this period.In such cases, the treatment is advised to be planned around the more aggressive malignancy. These patients should also be followed-up by dermatology due to the higher risk of secondary cutaneous malignancies.
