What term means a malignant tumor derived from glandular tissue?
adenocarcinoma – a malignant tumour originating in glandular tissue.

Which term means a tumor derived from the tissue of the thymus?

Which condition is a malignant derived from muscle tissue?
A sarcoma is a type of cancer that starts in tissues like bone or muscle.
Is thymus a lymph node?
The thymus differs structurally from other lymphoid organs in that it does not have lymphatic vessels draining into it. It is not a filter like the lymph nodes, which are situated so that microorganisms and other antigens are exposed to their cells.
Which masses of lymphoid tissue are also known as the nasopharyngeal tonsils?
adenoids, also called Pharyngeal Tonsils, a mass of lymphatic tissue, similar to the (palatine) tonsils, that is attached to the back wall of the nasal pharynx (i.e., the upper part of the throat opening into the nasal cavity proper). An individual fold of such nasopharyngeal lymphatic tissue is called an adenoid.
