The term "food allergy" refers to adverse immunologic reactions to food. Food allergy is usually mediated by IgE antibody directed to specific food proteins, but other immunologic mechanisms can also play a role. The primary target organs for food allergic reactions are the skin, the gastrointestinal tract and the respiratory system. Both acute reactions (hives and anaphylaxis) and chronic disease (asthma, atopic dermatitis and gastrointestinal disorders) may be caused or exacerbated by food allergy. The foods most commonly causing these reactions in children are milk, egg, peanuts, soy, wheat, tree nuts, fish and shellfish; in adults, they are peanuts, tree nuts, shellfish and fish. The diagnosis of food allergy requires a careful search for possible causes, confirmation of the cause(s) with supporting tests, including specific tests for IgE (i.e., prick skin tests, radioallergosorbent tests) and, in some cases, oral food challenges. Treatment consists of elimination of the causal food(s) along with medical treatment, including the prompt self-administration of epinephrine in the event of a serious reaction.
STUDY DESIGN: A case report. OBJECTIVES: To report and discuss a case of lymphangioma presenting as a dumbbell-shaped tumor in the epidural space of the lumbar spine. SUMMARY OF BACKGROUND DATA: Dumbbell tumor of the spine is not uncommon. Although the pathogenesis of such tumors varies widely, lymphangioma has not been reported previously, to these authors' knowledge. METHODS: A 56-year-old woman with pain in the lower back and left leg was examined by plain radiographs and magnetic resonance imaging before surgery. Treatment consisted of the usual technique of surgical resection of the tumor. Histopathologic study of the resected material confirmed the diagnosis. Postoperative follow-up assessment was performed by magnetic resonance imaging. RESULTS: Magnetic resonance imaging demonstrated a dumbbell tumor in the epidural canal area of the lumbar spine. Histopathologic diagnosis of the resected tumor was cavernous lymphangioma. CONCLUSION: To the authors' knowledge, this is the first reported case of lymphangioma presenting as a spinal dumbbell tumor. Further observation is recommended because of the possibility of local recurrence.
