(Appendix L-Cell Glucagon-Like Peptide-Producing Neuroendocrine Tumor, NCI Thesaurus)
Several morphologic patterns have been identified and include insular, gyriform, trabecular, pseudosarcomatous, and solid.
(Adult Type Testicular Granulosa Cell Tumor, NCI Thesaurus)
Excessive formation of dense trabecular bone leading to pathological fractures, OSTEITIS, SPLENOMEGALY with infarct, ANEMIA, and extramedullary hemopoiesis (HEMATOPOIESIS, EXTRAMEDULLARY).

Histologically, it is classified as insular, trabecular, mucinous, or stromal carcinoid.
(Ovarian Carcinoid Tumor, NCI Thesaurus)

(Merkel cell carcinoma, NCI Thesaurus)
Contraction of longitudinal muscle pulls on the scleral spur, and opens the trabecular meshwork, thereby increases aqueous humor outflow from the eye and reduces intraocular pressure.
(Echothiophate Iodide, NCI Thesaurus)
Glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris.
(Open Angle Glaucoma, NLM, Medical Subject Headings)
When applied topically to the eye, this agent stimulates the sphincter pupillae to contract, resulting in miosis; stimulates the ciliary muscle to contract, resulting in spasm of accomodation; and may cause a transitory rise in intraocular pressure followed by a more persistent fall due to opening of the trabecular meshwork and an increase in the outflow of aqueous humor.
