Surgical treatment of male breast cancer metastasis to thoracic spine: A case report.

PURPOSE: We present a rare clinical case of a metastatic spinal tumor in the 7th thoracic spine from male breast cancer (MBC). METHOD: A 62-year-old man was referred as an outpatient, complaining of continuous pain in the back and right flank that began 2 weeks earlier. The patient had no neurologic signs or symptoms but had a medical history of left breast modified radical mastectomy because of MBC. Computed tomography and magnetic resonance imaging showed metastasis in the T7 vertebra and no other metastasis on positron emission tomography/computed tomography or bone scan. Separation surgery was performed with posterior corpectomy of T7 (en bloc excision), followed by stabilization with an expandable titanium cage and pedicle screws. The pathological examination of the excised T7 vertebra confirmed metastatic carcinoma with neuroendocrine differentiation from the breast. Adjuvant chemo-radiotherapy was performed after surgery. RESULTS: The patient had no symptoms at the 21-month follow-up. Radiologic studies showed no evidence of recurrent or metastatic lesions. CONCLUSION: MBC is extremely rare, with fewer cases of spinal metastases. Among these, patients who undergo separation surgery are even rarer. This case shows that radical surgery can be an option for MBC with spine metastasis if indicated.

Volar wrist ganglion associated with radial artery atherosclerosis: A case report.

RATIONALE: There have been no reports of volar wrist ganglions being associated with atherosclerosis of the radial artery. Good results were obtained with radial artery reconstruction through ganglion excision and autogenous vein grafting. Hence, we report a previously unreported case, along with a review of the literature. PATIENT CONCERNS: A 58-year-old female presented with the chief complaint of a mass on the volo-radial side of her right wrist. The patient complained of a tingling sensation in the thumb, index, and extensor zones that worsened when pressing the mass. DIAGNOSES: Sonography revealed a well-defined, anechoic cystic lesion adjacent to the radial artery. INTERVENTIONS: Exploration was performed using a zig-zag incision on the mass. The superficial radial nerve (SRN), which innervates the thumb, was distorted by the mass and the nerve dissected from the mass. However, the artery and ganglion cysts were not separated completely in a part where hardening of the artery wall progressed as a result of degenerative changes, showing multiple small, hard, and yellowish masses. We resected the radial artery (approximately 1.5 cm) along with the ganglion and sent it for histological examination. The radial artery was then reconstructed using an autogenous venous graft. OUTCOMES: At the 34-month follow-up, the patient was asymptomatic. Radial artery patency was normal without recurrence of the ganglion cyst. LESSONS: In patients with risk factors for radial artery atherosclerosis, a more careful diagnosis is required for the surgical treatment of the volar wrist ganglion. In addition, if the ganglion and radial artery are not completely dissected, excision of the radial artery and subsequent reconstruction of the radial artery using an autogenous vein may be a good surgical strategy.
