Diagnosis
The diagnoses of NKCE and LG depends on clinical and pathological findings indicating that the two diseases: a) are indolent and non-malignant; b) usually manifested by mild, vague, or no symptoms; c) localize to the GI tract without involvement of the head, neck, or organs such as the liver and spleen; d) consist of one or more lesions localized primarily to the lamina propria of the esophagus, stomach, small intestine, and/or large intestine (for NKCE} or to the stomach (for LG); and e) involve lesions which contain medium-to large-sized, atypical, and non-clonal lymphocytes that are activated NK cells (see Pathophysiology section) which proliferate at moderately rapid rates (as gauged by, e.g. analysis of their Ki-67 protein levels), lack evidence of Epstein-Barr virus infection, gene mutations, or chromosome abnormalities, and show little evidence of centering around, and destroying, blood vessels. Differential diagnosis
In early studies, aggressive chemotherapy with or without bone marrow translanton and gastric resections were used to treat NKCE and LG, respectively, based on the assumptions that these diseases were malignant. Since there was no evidence that these treatments influenced the underlying disease and since NKCE and LG are essentially benign disorders, they must be distinguished from the malignant diseases which they mimic. Three malignant or potentially premalignant diseases which can closely resemble NKCE and LG along with some clinical and laboratory findings which differentiate them from NKCE and LT are:

Extranodal NK/T cell lymphoma, nasal type: This disease can closely mimic NKCE and, to a lesser extent, LG.
Cycloplegia is also helpful in relieving accommodative spasm. History
Cyclopentolate was first synthesized in 1952 as a chemical analogue of atropine. It was one of several derivatives of an analogue to tropic acid which were tested for pharmacological action "in a search for new and better antispasmodic agents. "Brand names for cyclopentolate include Cyclogyl, Cylate, Mydrilate, and Pentolair. References
