RESUMO
BACKGROUND: Angiosarcoma is a rare malignant tumor. Owing to the lack of specific clinical manifestations of this disease, it is difficult to achieve early diagnosis and start early treatment. CASE SUMMARY: A 78-year-old male patient was admitted to the hospital because of a bump on his head that did not heal for 4 mo. The patient was diagnosed with a refractory head wound. The patient underwent neoplasm resection and skin grafting surgery in the Plastic Surgery. The neoplasm was sent for pathological examination during the operation. The final pathological results were confirmed scalp angiosarcoma. CONCLUSION: Our research suggests that pathological examination should be performed for refractory ulcers of the scalp, and physical factor therapy should be used with caution before the diagnosis is clear.
