We report a rare case of pleomorphic adenoma arising from the nasal septum. A 37-year-old woman presented with a 1-year-history of right-sided occasional epistaxis. Computed tomographic scans revealed an oval mass in the right nasal cavity. The tumor was removed endoscopically with endonasal approach. The microscopic finding showed numbers of myoepithelial cells and duct-like structures consisting of loose myxoid stroma. This lesion had histological characteristics of a pleomorphic adenoma, and this was confirmed by immunohistochemical expression of cytokeratin, S-100 protein and SMA. Her post-operative course was uneventful, and she is currently free from the disease 1.5 years after surgery.

Objective To study the mechanism of glutamine dipeptide on wound healing after operations on bums. Methods Totally, 30 burned patients were randomly divided into study group and control group (15 cases in each group). All patients received parental nutrition support after operation. Study group patients were supplemented with glutamine dipeptide at a dose of 0. 5 g ·kg-1· d-1. The plasma free hydroxyproline level was measured by a standard amino acid analyzer 1 day before operation and 7 days after operation and the wound healing time was recor- ded. Results The plasma free hydroxyproline levels of both groups were higher than the normal values before opera- tion but without significant difference [control group: (2. 24±0. 84) μg/ml, study group: (2. 32±0.92) jig/ml, normal value: (1.27±0.44) μg/ml]. On the post-operative 7 day, the plasma free hydroxyproline level of study group [ (4. 31±1. 05) ng/ml] was significantly higher than that of control group [ (3. 04±1. 01) μg/ml] (P = 0.002). The wound healing time of study group [ (29. 7±5.3) d] was shorter than that of control group but with- out significant difference [ (33. 3±7.5) d, P = 0. 14 ]. Conclusion The intravenous supplementation of glutamine dipeptide may increase the plasma hydroxyproline level after operation and thus promote wound healing.
