Azzopardi phenomenon

From WikiMD's Wellnesspedia

Azzopardi phenomenon is a histopathological entity observed in certain types of cancer, particularly lung cancer and gastric cancer. It is named after the pathologist George Azzopardi who first described it in 1973.

Overview[edit | edit source]

The Azzopardi phenomenon is characterized by the presence of necrosis (cell death) and hemorrhage (bleeding) in the walls of blood vessels within a tumor. This is accompanied by the deposition of DNA from dead tumor cells on the walls of these blood vessels. The DNA appears as a dark, smudgy material under the microscope, a feature that is characteristic of the Azzopardi phenomenon.

Clinical Significance[edit | edit source]

The Azzopardi phenomenon is a significant finding in the diagnosis of certain types of cancer. It is particularly associated with small cell lung cancer and gastric adenocarcinoma, but can also be seen in other types of cancer. The presence of the Azzopardi phenomenon can help pathologists to differentiate between different types of tumors and can provide important information about the aggressiveness of the tumor.

History[edit | edit source]

The Azzopardi phenomenon was first described by the Maltese pathologist George Azzopardi in 1973. He observed this phenomenon in a series of lung cancer cases and noted its potential diagnostic significance. Since then, the Azzopardi phenomenon has been reported in a variety of other cancers and has become a well-recognized feature in the field of pathology.
