The Diagnosis of a Case of Household Cleaner Fatality.

Household cleaners are an unavoidable entity in our routine domestic life. They are available either in company-labeled bottles or locally made unlabeled bottles especially in the developing countries. In this report, we are discussing a case of fatal ingestion of household cleaner, which was stored in an unlabeled bottle. The deceased developed features of gastrointestinal irritation, such as vomiting and pain in throat and abdomen. He also had features of aspiration such as cough and chest crepitation. Finally, he developed metabolic acidosis, gastric perforation, respiratory failure, and died within a day. The autopsy features such as teeth discoloration, corrosion of mouth and lips, and histopathological findings helped us in concluding that the ingredients contained some corrosive mineral acid. This case highlights the importance of histopathological examination of viscera in alleged cases of household cleaner poisoning where toxicological analysis of viscera gives negative results.

Rhabdomyolysis associated acute renal failure - Report of two fatal cases and a brief review of literature.

BACKGROUND: Rhabdomyolysis is a potentially fatal condition which occurs due to skeletal muscle injury and classically presents with myalgia and red-brown coloured urine. Presence of excess myoglobin in the glomerular filtrate forms myoglobin casts which causes severe obstruction and necrosis of the tubules leading to acute renal failure. METHODS: We report two fatal cases of rhabdomyolysis associated acute renal failure. The first victim died in police custody and the second victim died due to severe physical exertion. RESULTS: In both the cases, creatine kinase levels were elevated and myoglobin was detected in urine in the second case. Myoglobin immunohistochemistry detected the presence of myoglobin cast in the glomerular tubules of kidney in both the cases. CONCLUSIONS: Myoglobin immunohistochemistry of renal tissues, serum creatine kinase, urine myoglobin analysis and muscle histopathology are the laboratory tests that should be considered at autopsy where rhabdomyolysis is suspected.

Primary Intraocular Malignant Rhabdoid Tumor Mimicking Retinoblastoma in a Child.

Primary rhabdoid tumors are highly malignant, rare tumors occurring in the renal, extrarenal soft tissue or central nervous system. They have non-specific radiological features and present with several histological components that create a problem in differential diagnosis with other embryonal tumors. We report a rare case of malignant rhabdoid tumor of the retina that presented with clinical features like those of retinoblastoma.

Colon Perforation by Compressed Air: A Case Report and Short Review of Literature.

Barotrauma-associated perforation of the colon is not common and usually occurs due to the passage of compressed air through the anus. Most of the cases are accidental and done for fun often at the victim's workplace. Therefore, it is necessary that the workers should be made aware of the dangers of the equipment they regularly use at their workplace. Here, we describe one such case where a rice mill worker died when compressed air through an air pump pipe entered his rectum. His chief complaint was abdominal pain and breathing difficulty. Computed tomography scan of the abdomen and thorax showed pneumoperitoneum, pneumomediastinum, and soft tissue emphysema. There was a complete tear in the rectosigmoid junction of the colon. The mucosa was deeply hemorrhagic and congested. Histopathology of this segment showed hemorrhagic necrosis of the mucosa.

Bronchial brush cytology of primary anaplastic large cell lymphoma of lung.

Primary pulmonary lymphoma is defined as clonal lymphoid proliferation affecting one or both lungs in a patient with no extrapulmonary involvement at the time of diagnosis or during the subsequent 3 months. Anaplastic large cell lymphoma (ALCL) is a rare T-cell neoplasm which occurs as two distinct clinical entities-cutaneous and systemic variant. Primary lung involvement is extremely uncommon. It can be classified on the basis of being positive or negative for ALK rearrangement which carries prognostic significance. The 2016 revision of World Health Organization (WHO) classification of lymphoid neoplasm recognizes three types of ALCL namely ALK-positive, ALK-negative, and breast implant associated. Here, we report a case of primary pulmonary ALK-1 positive ALCL which was initially recognized in bronchial brushing cytology based on distinct morphologic clues.
