Extranodal non-hodgkin lymphomas of the oral cavity and maxillofacial region: a clinical study of 58 cases and review of the literature.

Purpose: Approximately one third of non-Hodgkin lymphomas (NHLs) arise in tissues other than the lymph nodes. The purposes of this study are to evaluate the clinical outcome of NHLs of the oral cavity and maxillofacial region in a group of 58 patients who were diagnosed in our clinic and to discuss the clinical, histologic, and immunohistochemical features of these malignant neoplasms, as well as the prognosis.

Materials And Methods: The study included 58 patients with extranodal NHLs of the oral cavity and maxillofacial region.

Chromatographic behavior of zwitterionic enalapril-exploring the conditions for lipophilicity assessment.

The chromatographic behavior of enalapril was investigated under different stationary and mobile phase conditions in an effort to unravel interferences in the underlying retention mechanism, which would affect its relation to octanol-water partitioning. Extrapolated retention factors, logk(w), were used as relevant chromatographic indices. The retention/pH profile was established and the peak split phenomenon, associated with cis/trans interconversion, was also monitored as a function of pH.

Management of adenoid cystic carcinoma of minor salivary glands.

Purpose: Adenoid cystic carcinoma (ACC) is a rare malignant tumor originating from the salivary glands. The characteristic clinicopathologic features of this tumor are perineural spread, local recurrences, and distant metastases. Radical surgery combined with radiotherapy, as mentioned in the literature, is the best method of treatment.
