One in 10 patients with ischemic stroke has comorbid cancer. Our goal was to compare stroke patients with cancer against those without cancer in terms of clinical and radiological features, and the underlying mechanism. We conducted a retrospective case-control study in patients admitted with ischemic stroke between July 2013 and September 2018. ⋯ Small artery disease as the etiology of stroke was significantly less common in the cancer group (2% vs. 26%, p = 0.001). Regarding neuroimaging, the embolic pattern was more frequent in patients with cancer (82% vs. 35%, p = 0.001). In these patients recurrence and mortality at 90 days was three and six times higher (10% vs. 3%, and 18% vs. 3%. p = 0.08 and 0.001, respectively).

Malignant syphilis occurs frequently in patients infected with human immunodeficiency virus (HIV) and presents with cutaneous nodular lesions that tend to ulcerate. Non caseating granulomas are among the most conspicuous histopathological findings and require differential diagnosis with other infectious and non-infectious granulomatous conditions. The evolution of the disease is usually favourable with penicillin treatment. We present the case of an HIV-positive patient who meets diagnostic criteria for malignant syphilis and alert on this infrequent granulomatous entity.
