Periprosthetic metastasis following total hip arthroplasty in a patient with lung carcinoma: A case report and review of literature
Rationale:
Periprosthetic osteolysis secondary to septic loosening and aseptic loosening is a well-described phenomenon associated with artificial hip arthroplasty. Periprosthetic bone loss as a result of metastatic infiltration is an uncommon cause of early, progressive loosening of joint replacement prosthesis and is rarely described in the literature.
Patient concerns:
The present study describes a 70-year-old male patient who was diagnosed with pulmonary squamous cell carcinoma 5 years after total hip arthroplasty (THA) and developed a metastasis from squamous cell carcinoma in the periprosthetic neosynovial tissue 1 year after formal chemotherapy. The main complaint was hip pain with limited activity for about 3 months.
Diagnoses:
Expansive bone destruction and periprosthetic osteolysis at the right femoral trochanter were identified through X-ray and 99mTc bone scan. The diagnosis of pulmonary squamous cell carcinoma metastasis was finally confirmed on the basis of postoperative pathological examination.
Interventions:
The patient underwent open surgery with proximal femoral prosthesis revision and tumor prosthesis resection to completely remove the tumor tissue and relieve pain.
Outcomes:
The patient was completely relieved of pain at discharge 2 weeks after surgery and experienced no complications. However, the patient died of respiratory failure due to disease progression 3 months after surgery.
Lessons:
We believe that clinicians should maintain a h...
