AtLP are conditions in which it is not possible to differentiate between the benign and the malignant nature of a given lymphoid infiltrate. The descriptive term AtLP may be used as an interim label when morphologic and molecular features are not sufficient to render a positive diagnosis of lymphoma.
Great Barrier Reef. Sitting off the east coast of Australia, the Great Barrier Reef is the worldâs largest coral reef system, covering more than 344 000 sq km. The reefâs diversity of life faces numerous threats such as climate change, pollution, fishing and outbreaks of the coral-preying crown-of-thorns starfish.
Reefs, which are usually made up of many colonies, are much bigger still. The largest coral reef is the Great Barrier Reef, which spans 1,600 miles (2,600 km) off the east coast of Australia. It is so large that it can be seen from space! It takes a long time to grow a big coral colony or a coral reef, because each coral grows slowly.
