The coexistence of lymphangiosarcoma and Kaposi's sarcoma in a renal transplant recipient

Multiple unrelated malignancies following renal transplantation: an evaluation of four cases

The risk of de novo malignancy is significantly higher in patients who have undergone organ transplantation than in the general population. Long-term immunosuppressive treatment, in addition to age, genetic predisposition and infectious agents, plays a major role in the development of malignancy. Although skin and hemopoietic system cancers are common, atypical presentations of malignancies may occasionally be seen during long-term follow-up in patients with functioning allografts. In this report, four cases, each with more than one different primary malignancy (one patient with three malignancies and three patients with two malignancies), are presented.

Lymphangiosarcoma. Reports of 3 cases and review of the literature

Three cases of lymphangiosarcoma have been followed recently. All were finally treated by amputation. Only one is actually disease-free. The other two developed local recurrence at the thoracic cage. An extensive review of the literature follows the case presentation.

Primary angiosarcoma of the alveolar mucosa in a haemodialysis patient: case report and discussion

A case of a haemodialysis patient with a primitive angiosarcoma of the alveolar mucosa is reported. The vascular origin of the tumor was confirmed by the immunohistochemical data which showed strong positivity for Factor VIII-related antigen and for vimentin, whereas stains for desmin and cytokeratins were negative.
