Myopericytoma of the patella with local recurrence and patellectomy: A case report
INTERNATIONAL JOURNAL OF SURGERY CASE REPORTS(2024)
摘要
Introduction and importance: Myopericytomas are tumors originating from perivascular myoid cells and exhibiting a wide range of histologic growth patterns. They rarely occur in bones, and no case of myopericytoma in the patella has been reported so far. Case presentation: A 74-year-old male presented with a chief complaint of pain in the left knee. Magnetic resonance imaging revealed bone tumor and osteolytic lesions of the patella. The patient underwent bone tumor curettage and filling of the cavity with artificial bone. However, as the tumor reoccurred, a patellectomy was performed. The patient regained premorbid functional status after surgery. Additionally, there was no radiological evidence of recurrence of the lesion 3 years after patellectomy. Clinical discussion: Myopericytoma of the patella is very rare. However, it should be considered for the differential diagnosis of lytic lesions of the bone. Although surgery is curative, patellectomy may be necessary for recurrent cases. Conclusion: In conclusion, we report the first case of patellar myopericytoma. Although patellar myopericytoma might be rare, it should be considered for the differential diagnosis of lytic lesions of the bone. Surgery is curative; however, patellectomy may be necessary in recurrent cases.
