The case is reported of a patient with gastric adenocarcinoma with metastases who developed a septic focus in a saphenous vein. Salmonella enteritidis was cultured from blood, sputum and stool specimens, and from a thrombus removed from a varicosity of the saphenous vein. Extraintestinal infections caused by non-typhoid salmonella usually afflict debilitated and immunocompromised patients. Metastatic septic foci may appear anywhere in the organism, including the vascular system, but involvement of the venous system has not previously been reported.

Capillary microscopy is an easy, noninvasive procedure to examine in vivo the dermis capillaries of the nailfold. It has demonstrated clinical use in the etiologic study of Raynaud's phenomenon. We consider a "vascular activity pattern" to be present at capillary microscopy when one of the following associations is observed: tortuous capillary vessels plus ramifications with or without loss of a moderate amount of capillaries. Capillary tortuousity alone is not considered pathologic. It is well known that bleomycin (BLEO) can occasionally induce vascular-associated diseases. To examine the vascular damage produced by BLEO, we performed capillary microscopic studies on 40 patients with neoplasia, 21 of whom had received BLEO during the previous year. The maximum accumulated doses ranged from 15 to 379 U. The other 19 patients had advanced neoplasia, and 10 of them had received antitumoral combinations that did not contain BLEO. No one had clinical signs attributable to vascular toxicity. Twenty-six patients had no pathologic patterns (11 received BLEO and 15 did not). In the group of 14 patients with activity patterns, 10 had received BLEO and 4 had not (P = 0.035). Ten of 11 patients treated with BLEO who had normal capillary microscopic studies received total doses of less than 100 U. We conclude that capillary microscopy may demonstrate the vascular damage induced by BLEO even in asymptomatic patients.Cancer 65:303-309. 1990.
