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.

BACKGROUND: Cutaneous manifestations of vasculitis can be seen as pleomorphic lesions; purpura, erythema, nodule, bulla, ulcer and so on. In cases of polyarteritis nodosa (PAN), cutaneous presentations of small artery pathology may be seen in about one fourth among those patients with systemic form of PAN, and in all cases of cutaneous form subset. OBJECTIVE: To examine the pattern or morphology of cutaneous lesions found in the skin (especially on the lower legs) among Korean patients with cutaneous form of PAN. Patients AND METHODS: Eight patients with diagnosis-confirmed cases of cutaneous PAN were examined regarding the patterns of cutaneous lesions, as well as possible local symptoms, distributions, duration, and any positive findings in laboratory examinations and systemic review. RESULTS: Clinical patterns of cutaneous lesions observed in the lesional areas among those 8 patients were mottled or atypical reticular erythema (5 cases), subcutaneous nodules (3 cases), scattered erythematous patch (3 cases), ecchymotic erythematous patch (3 cases) and superficial ulcer (1 case). Tenderness was detected at the nodular lesions; predilection site were shin and calf areas; a few laboratory abnormalities and systemic symptoms were found regardless of the duration of skin lesions. CONCLUSION: Common clinical patterns of cutaneous lesion recognized with 8 patients of cutaneous PAN were mottled/atypical reticular erythemas, subcutaneous nodules, erythematous/ecchymotic patches, and these in all cases were seen at the lower legs. In patients with each different clinical presentation, there were no relevancies between the duration and severity of the disease.

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.
