mucoid

[′myü‚kȯid]

Any of various glycoproteins, similar to mucins but differing in solubilities and precipitation properties and found in cartilage, in the crystalline lens, and in white of egg.
Resembling mucus.

Mucoid

 

an obsolete term applied to carbohydrate-protein compounds present in a variety of biological matter, such as egg white, cornea, cartilage, vitelline membranes of amphibian and invertebrate eggs, synovia of the joints, secretions of the salivary glands, ovarian cysts, and blood plasma. In view of their chemical structure, it has been suggested that mucoids be called mucopolysaccharides or glycoproteins.

Histologically, leiomyosarcoma and IMT may have components of spindled cells with fibrillar eosinophilic or vacuolated cytoplasm; the background stroma may be extensively myxoid and in both may include aggregates of inflammatory cells, predominantly lymphocytes and plasma cells; although leiomyosarcoma typically exhibits at least mild to moderate nuclear pleomorphism, necrosis and atypical mitotic figures.
