Abstract: Lymphoid papillary hyperplasia is a rare abnormality of the tonsils with a predilection for affecting young Asian girls. Herein, we report
a 31-year-old Chinese woman presented as right lateral recurrent tonsillar hypertrophy with odynophagia and dysphagia over the past 5 years,
worsening over a period of for half a year. Clinically, this lesion was similar to papillomatosis or lymphoid polyposis. However, histopathologic
study showed a distinctive form of lymphoid hyperplasia with considerable distinct finger-like projections composed of many phyllodes which
contained remarkable follicular lymphoid hyperplasia. This is the only Chinese case of lymphoid papillary hyperplasia of the palatine tonsils
that has been reported in the most recent English literature so far. The importance of recognizing this disorder rests in the fact that in spite of
the clinical features suggestive of both a benign and a malignant tumor, however, the process is a benign tumor-like proliferation, probably
non-neoplastic, could easily be cured by tonsillectomy. (IJCEP1307012).
