    ABSTRACT: Coronary artery disease, one of the leading causes of worldwide adult mortality, is most commonly atherosclerotic in pathogenesis. Nonatherosclerotic etiologies are quite rare. In the latter category, infective arteritis or infective vasculitis of the coronary arteries is a very rare but well-recognized subtype, usually discovered at autopsy. In this article, we present the clinicopathologic necropsy data of 10 patients in whom infective coronary arteritis was the leading cause of death. Among the 10 cases, the male/female ratio was 6:4, and with the exception of a 2-year-old female child, all the other patients were adults with an age range of 26 to 59 years. Of the 10 cases, 6 had infective endocarditis along with history of rheumatic heart disease in 3 patients, whereas 2 other patients had strong clinical suspicion of bacteremia or septicemia. The remaining 2 cases had preexisting coronary atherosclerosis with a history of stent placement in 1 of them. All our cases showed on histopathology acute obliterative inflammatory infiltrate consisting mainly of neutrophils along with bacterial colonies (in most of them) involving the epicardial and intramural coronary arteries. To the best of our knowledge, this is the largest series of infective coronary arteritis to be reported in the world.

    ABSTRACT: Myxomas are the most common among the primary cardiac neoplasms, seen mainly in adult population, and are typically attached to the interatrial septum, on the left side. Myxomas arising from other sites are designated as "atypical myxomas." In this article, we describe the clinicopathologic features of 28 such lesions, resected in 20 patients. A 15-year study (1995-2009) of all cardiac myxomas, received as surgical excisions in our institution, was performed. Atypical myxomas were selected on the basis of their atypical sites of origin, and a systematic review and comparison of their clinicopathologic features with all typical myxomas excised during the same period were done. Among a total of 84 patients who had undergone cardiac myxoma excisions in this 15-year duration, 64 patients had typical myxomas, while atypical myxomas (30 tumors) were diagnosed in 20 patients (23.8%). None of them had a family history of similar symptoms. There were six children. In the atypical subset, there were 12 males and eight females; the mean age of diagnosis was 33.7 years. This demography differed from the typical myxoma group where there were more females than males and the mean age of diagnosis being 40.8 years. The symptoms of dyspnea, episodic chest pain, and palpitation were common in both cohorts of patients, and all showed a mass lesion with varying degrees of valvular regurgitation and obstruction on echocardiography. Five of the 20 patients with atypical myxomas had multifocal or multicentric tumors. Grossly, like typical myxomas, the atypical ones also exhibited solid and papillary patterns with the usual histological features. Four patients had recurrence of the disease. Atypical myxomas are rare lesions having clinical and pathological features, not entirely different from those of typical myxomas. With the advent of modern diagnostics, it is now imperative to do genetic studies and screen the relatives of patients having atypical myxomas to rule out additional occult familial cases as they are now known to occur more in this "atypical" group.
