Cardiac tumors range from benign to high grade malignancies. The incidence of cardiac involvement either by primary, or secondary tumors during autopsy is reported to be extremely low. Extranodal NK/T-cell lymphoma (ENKTL), nasal type is an unusual type of lymphoma. The skin is the second most common site of involvement after the respiratory tract. We present a case of a 63-year-old male, who was recently diagnosed with ENKTL, nasal type, who received chemotherapy, and died without any evident cause. The corpse was referred for routine medicolegal examination. Macroscopical determination of the cause of death was not feasible and subsequent histopathological examination revealed heart infiltration by ENKTL that was found in vivo in cutaneous lesions. Similar infiltrations existed in the pancreatic tissue. To the best of our knowledge, myocardial infiltration of ENKTL, inducing severe myocardial lesions that eventually caused death, is rare, with limited cases reported in the literature.

Background & Objectives: Respiratory, central nervous system, and skin complications of mustard gas toxicity have previously been studied; however, the liver and kidney side effects due to this intoxication have not been fully noted. We aimed to evaluate the frequency of liver, kidney and lung lesions in mustard gas-exposed Iranian veterans who had been exposed to the toxin almost 2 decades before.
Methods: A total of 100 veteran bodies underwent autopsy by at least two forensic medicine specialists. The liver, kidney and lung specimens were sent for pathological examination and their lesions, severity of the lesions, and the relation between the type/severity of the lesions and the time elapsed since their appearance were studied.
Results: A total of 83%, 63%, and 62% of the veterans had lung, liver, and kidney pathologies. The most common pathologies included liver steatosis, interstitial fibrosis of the kidney, and lung atelectasis.
Conclusion: Liver and kidney pathologies are far more common than what is considered in the mustard gas-exposed veterans. These pathologies are often accompanied by very severe lung complications.

Background and Objectives: In spite of large number of studies conducted so far, sudden cardiac death remains an enigma and relative importance of acute coronary events as a trigger of sudden death is currently unclear. An autopsy study of heart was therefore planned to observe various histomorphological cardiac changes, and to determine the frequency association of acute coronary events and myocardial infarction with sudden death.
Material and Methods: A prospective randomized study of two hundred autopsied hearts submitted for postmortem analysis was conducted in the Department of Pathology, PGIMS Rohtak over a period of two and a half years from June 2007 to December 2009. The hearts were examined grossly and microscopically to observe various histomorphological changes and findings were correlated clinically.
Results: Out of 200 autopsied hearts, 142 (71%) revealed coronary artery atherosclerosis in one or more vessels. Maximum number of cases (32.5%) revealed three vessel diseases. Significant atherosclerosis (>50% reduction in diameter) was present in 125 (62.5%) cases, while 58 cases (29%) revealed no observable atherosclerotic change. One hundred twenty cases could be categorized under sudden cardiac death, 15.83% revealed changes of acute MI, 40% of healed MI and 44% revealed no change.
Conclusion: The ischemic heart disease was found to be the leading cause of death with coronary atherosclerosis being the most significant pathogenetic mechanism and three vessel disease the most common pattern of involvement. Acute coronary events (occlusive or non-occlusive thrombus/ plaque rupture/ haemorrhage) were observed in only 16% of the cases of sudden coronary death.

Background and Objectives: Infection with parvovirus may induce spontaneous abortion, non-immune hydrops fetalis, and intrauterine death in full term infants. The aim of this study was to determine the frequency of parvovirus B19 in paraffin-embedded formalin fixed placental tissues in lost fetuses by PCR method and comparison with its frequency in healthy full term neonates as controls.
Materials and Methods: In a case control study, thirty-one formalin fixed paraffin embedded placental tissue from autopsies related to fetal losses and also the same number of control cases were collected and The PCR for internal control and target sequence were performed.
Results: Thirty-one subjects and 31 controls were enrolled and three out of 31 cases were positive for parvovirus (9.7%) using PCR. Hydropic changes were noted in two of positive cases for parvovirus.
Conclusion: Parvovirus B19 infection during pregnancy may cause red precursor cells damage resulting in anemia and congestive heart failure. We suggest that studies with greater sample sizes are carried out to determine the frequency and management of parvovirus B19 infection because of timely diagnosis and transfusion of severe hydropic fetuses can reduce the risk of fetal death

Background and Objective: Ischemic heart disease (IHD) following atherosclerosis is the most common cause of cardiac deaths world wide. We aimed to investigate the pathologic features of atherosclerosis in non cardiac death cases to have an estimate of atherosclerosis prevalence in Mashad (North east of Iran). Patients and Methods : This descriptive (cross sectional) study was done, during October 2007 – March 2008, on 80 cadavers from 11 to 50 years old who had died of non cardiac causes and had no history of cardiac disease. After autopsy in forensic medical center, coronary arteries were removed and examined for atherosclerotic plaques. In case of a definite or suspicious lesion, microscopic slides were also prepared. Otherwise, three random slides from each branch of coronary arteries were studied by a pathologist. Results: We found that 73.1% of men and 61.5% of women had at least one fibrofatty or advanced plaque in major coronary arteries. Atherosclerosis in 41.8% of men and 30.8% of women was in advanced form. Frequency of advanced atherosclerotic plaques progressed with age reaching a maximum of 78.5% by the age of 41-50 years. In addition, prevalence of plaques suddenly increased after second decade of life. Atherosclerotic plaques were most commonly found in left anterior descending artery (60%) followed by right coronary (50%) and left circumflex (42.5%) arteries. Conclusion: This study showed an unexpectedly high prevalence of atherosclerosis in this population. It highlights the importance of cardiovascular risk factor screening from early ages of third decade.

Background and Objective: BCG vaccination is used in many countries with a high prevalence of TB to prevent childhood tuberculosis meningitis and miliary disease. Local and systemic sideeffects are associated with BCG vaccine. The most critical reaction is disseminated BCG infection which occurs in mostly immunodeficient patients. Materials and Methods: We performed 4 autopsies during 2001-2003 which were suspected for BCGosis clinically and histologically by presence of granulomatous foci in several organs with acid fast bacilli. The mycobacteria were identified by PCR. Their DNA was extracted from the tissue blocks, identified with primers which were designed to detect the RD1 deletion. Results: We found BCG genome by PCR in 3 out of 4 patients. These patients had acid fast bacilli in special staining. Conclusion: Since BCGosis is a fatal and uncommon disease, occurring after vaccination with numerous complications, its diagnosis is of paramount importance and should be considered in the appropriate clinical setting.
