However, unlike other oral lesions, KHE invades neighboring tissue planes and recurs frequently as malignancy. Moreover, some instances of KHE are accompanied by a life-threatening condition named Kasabach-Merritt phenomenon. Correct diagnosis of KHE is very difficult despite its importance. KHE lacks not only specific clinical characteristics, but also distinct imaging findings even with advanced modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). Thus, KHE is often misdiagnosed as another disease. We report a case of KHE in the mandibular gingiva. The enlarged gingival mass showed reddish granulomatous appearance with intact mucosal surface. It was misdiagnosed as another disease and underwent simple resection, but it recurred several times. In radiological examination using periapical radiography, cone beam computed tomography, and magnetic resonance imaging, no specific findings other than ill-defined alveolar bone destruction were observed.
