Cardiotoxicity manifested as myocardial ischemia is not generally recognized as a side effect of 5-fluorouracil. However, there have been at least 35 cases reported since 1975. In only one of these cases was a somewhat detailed evaluation done to rule out underlying coronary disease. The case reported here of 5-FU cardiotoxicity included an extensive cardiac evaluation to rule out underlying coronary disease and to assess spasm. The literature on 5-FU cardiotoxicity is also reviewed, and its possible mechanisms are analyzed.

We present photographic documentation of a broader spectrum of cutaneous lesions in the LMG-type angiocentric T-cell lymphoma than has previously been described, and have confirmed the association with EBV. The prognosis is poor. Aggressive therapy such as bone marrow transplantation should be considered early in the course.

Numerous ectopic hormones and markers have been described in small cell carcinoma of the lung as well as in extrapulmonary small cell carcinomas. The authors report a case of a patient with metastatic small cell carcinoma of unknown primary who had very high prostatic acid phosphatase (PAP) and prostatic specific antigen (PSA) levels. Results of multiple prostate examinations, as well as blind biopsies, were normal. His course was significantly longer than that of the usual patient with extensive small cell carcinoma. At autopsy the prostate showed only mild benign prostatic hypertrophy. There are no previous reports in the literature of abnormal prostate markers in small cell carcinomas. Physicians should be aware of the increasing complexity and the unusual biologic markers associated with neuroendocrine carcinomas. In some of these cases, the tumors ability to produce an ectopic product may portend an improved prognosis.
