Unusual infections associated with colorectal tumors may, in some instances, be the sole clue to the presence of a malignancy. The infections are either related to invasion of tissues or organs in close proximity to the tumor or secondary to distant seeding by transient bacteremia arising from necrotic tumors. Seven patients seen at one hospital over a 5-year period illustrate the clinical presentations of such infections. The infections identified in these seven patients include endocarditis, meningitis, nontraumatic gas gangrene, empyema, hepatic abscesses, retroperitoneal abscess, clostridial sepsis, and colovesical fistulae with urosepsis. A computer-assisted search of the English-language literature and cross-checks from other review articles identified other infections associated with colon cancer, which include nontraumatic crepitant cellulitis, suppurative thyroiditis, pericarditis, appendicitis, pulmonary microabscesses, septic arthritis, and fever of unknown origin. The clinical importance of these infections and their correlation with colorectal malignancies are reviewed.

The authors review the most common situation concerning oncological patients with concomitant thyroid disease. In case of unknown origin of metastasis and nodular goitre the ultrasound examination with fine needle aspiration biopsy confirms or excludes the thyroid origin. The euthyroid sick syndrome is often diagnosed in oncological patient as a consequence of oncological disease and it doesn't mean hypothyroidism. If oncological patients prove to have a thyroid functional failure the endocrinologist must correct the function as fast as possible to enable oncological treatment. There is no evidence that chemotherapy can influence the thyroid function, but radiotherapy can cause thyroiditis with later hypofunction. The interferon therapy causes thyroid dysfunction in 10% of patients and the recommendation to examine not only TSH and FT4 but also thyroid antibodies is warranted. Lymphoma of the thyroid gland occurs most often on the basis of lymphocytic thyroiditis and lymphocytic thyroiditis may be a risk factor for papillary carcinoma of the thyroid as well. Women with breast carcinoma were proved to have lymphocytic thyroiditis with minor thyroid hypofunction more often than the corresponding group of women with colon cancer or control group of healthy women. In case of renal tumor (Grawitz), breast or lung carcinoma the thyroid can be attacked with metastasis, and ultrasound with fine needle biopsy can reliably differentiate between primary or secondary thyroid involvements. The thyroid can be involved in some diseases: multiple endocrine neoplasia, Carney, Cowden and Gardner's syndromes.
