A 2-year-old girl had variably-sized, relatively well demarcated, depressed brownish patches on the left shoulder, back, and both legs from the age of 1 month. The biopsy specimen from the left shoulder showed an increase in the number of normal intradermal eccrine ducts and coils, which was compatible with pure eccrine nevus. The clinical manifestation of our case, including brownish depressed patches, was unique compared to other reported cases.

In this study, we describe our diagnosis and treatment of two patients who presented with femoral vessel compression caused by a cystic lesion in the groin. One case was diagnosed as adventitial cystic disease (ACD) of the common femoral artery resulting in leg claudication and the other was diagnosed as a ganglion cyst (GC) causing femoral vein compression and unilateral leg swelling. The operative findings differed between these two cases with respect to the dissection of the cyst and femoral vessel, but the postoperative histological examination results were similar. The pathogenesis of ACD and GC is not fully understood, and further investigation is needed to delineate the exact pathology of these uncommon conditions.

Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively. The nerve root was decompressed by shrinking the lesion with bipolar thermocoagulation and excision. The patient's complaints disappeared in the postoperative period. Thrombosed lumbar epidural varices may mimic lumbar disc herniations both radiologically and clinically. Therefore, must be kept in mind in the differential diagnosis of lumbar disc herniations. Microsurgical techniques are mandatory for the treatment of these pathologies and decompression with thermocoagulation and excision is an efficient method.

OBJECTIVE: Spinal fusion operation is an effective treatment in the spinal pathology, but it could change the physiological distribution of load at the instrumented and adjacent segments. This retrospective study compared the radiological and clinical outcomes of patients undergoing lumbar fusion with semirigid rods versus rigid rods system. METHODS: Using transpedicular fixation and posterior lumbar interbody fusion at the level of L4/L5, 20 patients were treated with semirigid rods (WavefleX, SR group), and 20 patients with rigid rods (titanium, RR group). Clinical and radiological outcomes were evaluated, including visual analog score for lower back pain and leg pain, Prolo functional and economic scores, statues of implanted instruments, fusion rate, and complications during 24-month follow-up. RESULTS: Clinical scores were significantly improved until postoperative 24-month follow-up as compared with preoperative scores in both groups (p<0.05), with similar levels of improvement observed at the same time points postoperatively between the 2 groups. Prolo economic scores were significantly improved in SR group compared to RR until 12 months, but this improvement became similar after 18 months. The overall fusion rate was 94.1% until the 24-month follow-up for both groups. No significant complication was observed in both groups. CONCLUSION: The results of the present study indicate that semirigid rods system with posterior lumbar interbody fusion showed similar clinical and radiological result with rigid rods system until 2 years after instrumentation. The WavefleX rods system, as a semirigid rods with unique characteristics, may be an effective alternative treatment for patients in lumbar fusion.
