Carcinoma is an epithelial-derived malignancy.
Carcinoma not otherwise specified, also carcinoma NOS, is a non-specific malignant diagnosis that without further information is not very useful for treatment decisions.
Generally speaking, pathologists try to be more specific when this is possible.
Carcinomas where the origin, i.e. primary site, is not known are cancers of unknown primary; this is dealt with separately in the article cancers of unknown primary.
