A case of microvenular hemangioma in a 23‐year‐old Japanese female Is described. The patient presented with a slowly growing, solitary reddish plague on her back, which measured 15 × 17 mm. Histologlcally, the tumor was an inflltrative growth throughout the dermls. It consisted of thin‐walled, small‐sized, irregularly branched vascular vessels. The vascular lumina were narrow. The flattened endothelial cells had oval to spindle‐shaped nuclei and scant cytoplasm that were immunohistochemically positive for endothelial markers. The tumor cells lacked cellular atypia, pleomorphism, and mitotic figures. The patient was well without disease 8 months after the excision. Pathologists and clinicians should be aware of the existence of this type of hemangioma with an infiltrative growth and avoid overdiagnosis and overtreatment.
