The formation of blastomas or tumor formation or the development of many tumors from embryonic tissue which is defined as a tumour composed of embryonic tissue that has not yet developed a specialized function.

1. A fungal infection causing lesions on the lungs, skin, or mucous membranes.
2. Infection with a fungus called Blastomyces dermatitidis.

It usually presents a flu-like illness with fever, chills, productive cough, myalgia, arthralgia, and pleuritic chest pain.

Some patients fail to recover and develop chronic pulmonary infection or widespread disseminated infection; affecting the skin, bones, and genitourinary tract. It occasionally affects the meninges which cover the brain and spinal cord.

People who are at an elevated risk for the disease are those in areas with endemic disease with exposures to wooded sites; such as, farmers, forestry workers, hunters, and campers. The disease can leave permanent lung damage.

Layers of body tissues: The diploblasts consist of animals; such as, jellyfish and hydra, that are supposedly derived from just two skin-like layers, and in the adult, consist of an outer layer of cells (a skin), an inner layer (a gut), surrounding a gelatinous and sometimes acellular layer called the mesoglea.

In zoology, relating to a body that is derived from only two embryonic cell layers (ectoderm and endoderm, but no mesoderm): Sponges and coelenterates are diploblastic, being aquatic invertebrate animals of phylum, and include jellyfish, corals, and sea anemones.

Dividing only in part, referring to an egg in which the cleavage divisions are confined to the animal pole, owing to the presence of a large amount of yolk.
