lung contusion: a clinico-pathological entity with unpredictable clinical course

lung contusion is an entity involving injury to the alveolar capillaries, without any tear or cut in the lung tissue. this results in accumulation of blood and other fluids within the lung tissue. the excess fluid interferes with gas exchange leading to hypoxia. the pathophysiology of lung contusion includes ventilation/perfusion mismatching, increased intrapulmonary shunting, increased lung wa...

Chronic ulcerative stomatitis: a distinct clinical entity?

Chronic ulcerative stomatitis (CUS) is a mucocutaneous disorder which is characterised by persistent oral mucosal ulceration. The clinical appearance is often reminiscent of oral lichen planus (OLP) leading to erroneous diagnoses. The immune mediated inhibition of the CUS protein (CUSP) is implicated in the pathogenesis of CUS. CUSP acts as an anti-apoptotic protein and when its action is preve...

Chronological Endoscopic and Pathological Observations in Russell Body Duodenitis

A 64-year-old man was found to have a nodule in his right lung. He also complained of nausea and abdominal pain during the clinical course. Esophagogastroduodenoscopy revealed a duodenal ulcer associated with severe stenosis and a suspicion of malignancy. However, three subsequent biopsies revealed no evidence of malignancy. The fourth biopsy showed scattered large eosinophilic cells with an ec...
