Morphological Changes of Coronary Arteries in Cases of Sudden Death due to Cardiac Causes - An Autopsy-Based 10-Year Retrospective Study.

Introduction: Ischemic heart disease (IHD) is the most common cause of cardiac deaths worldwide, mainly due to atherosclerosis. Prevalence of atherosclerosis evaluation, in an autopsy-based study, can be a valuable tool on subjects who died of cardiac causes. With this hypothesis, we conducted this 10-year retrospective study on the hearts of subjects who died due to cardiac causes.

Multilocular cystic renal cell carcinoma in a 23 year old female.

Multilocular cystic renal cell carcinoma (MCRCC) has been identified as a separate subtype of renal cell carcinoma (RCC) in the 2004 World Health Organization classification of adult renal tumors. MCRCC represents a rare variant of clear cell RCC. The common age group for this tumor is between 40 and 60 years.

"Mixed germ cell testicular tumor" in an adult female.

The androgen insensitivity (testicular feminization) syndrome was described by Morris in phenotypic females with 46XY karyotype, presenting with primary amenorrhea, adequate breast development, and absent or scanty pubic or axillary hair. Gonads consist usually of seminiferous tubules without spermatogenesis. These patients have a 5-10% risk of developing germ cell tumors, usually after the complete development of secondary female sexual characteristics.

"MacCallum Plaque of the Heart": A Medicolegal Case.

Mural endocardial lesions can be seen as MacCallum plaques in rheumatic heart disease. These plaques appear as map-like areas of thickened, roughened, and wrinkled part of the endocardium in the left atrium. Perhaps they are caused by regurgitant jets of blood flow, due to incompetence of the mitral valve.
