Abstract
Angiolymphoid hyperplasia with eosinophilia (ALHE) is very rare in the oral cavity and its cause is unknown. We herein report a case of ALHE which originated in the tongue. A 76-year-old female presented at our hospital with a chief complaint of a mass and pain on the left side of her tongue. The firm tumor was granulous and partially ulcerative on the surface. The superficial lymph nodes were not palpable. The eosinophil count and the IgE level in the peripheral blood were normal. The tumor was removed under local anesthesia in May 1997. A histological examination revealed a proliferation of hyperplastic vessels lined by plume endothelial cells and a diffuse cellular infiltration comprising lymphocytes and eosinophils, but no formation lymphoid follicles. The tumor was clinically and histologically diagnosed to be ALHE in the tongue. A local reccurence appeared 1.5 months after the first operation and thus the tumor was again removed under local anesthesia in June 1997. After the reoperation there has been no evidence of reccurrence of the tumor for 11 months.
