Epithelioid hemangioma is an unusual, which was at first described as angiolymphoid hyperplasia with eosinophilia(ALHE) in 1969 and misinterpreted as the same disease with Kimura’s disease. But now it represents a distinctive vasculartumor, a different entity with those inflammatory conditions. Here, we present a case of epithelioid hemangiomaappearing as a diffuse gingival nodular mass in 33‐year‐old male who had suffered from the idiopathic sharp pain of leftmandible area previously and later extended to left maxillary region, therefore the gingival lesion was clinically estimatedas malignancy associated with neural invasion. CT images revealed the soft tissue mass restricted to left maxillarygingiva without infiltration to underlying maxillary alveolar bone. Histologically, the circumscribed soft tissue massconsist of solid sheets of epithelioid to spindled cells, expressing reactivity for neither cytokeratin AE1/3 nor HMB‐45,but for CD31, endothelial cell marker. Therefore, the lesion was pathologically diagnosed as epithelioid hemangioma.Diagnostic evaluation for the neurologic symptoms of the patient revealed the trigeminal neuralgia, accompanying withthe present epithelioid hemangioma incidentally. Awareness of epithelioid hemangioma should be emphasized not to bemisdiagnosed as malignant disease like an invasive squamous cell carcinoma, malignant melanoma, or angiosarcoma. Properevaluation and interpretation for neural symptom may lead to the correct differential diagnosis and therapeutic intervention.
