Metallosis has been reported in the setting of weight-bearing joint arthroplasties, like the hip and knee joints. However, the prevalence of metallosis in non-articular portions is very uncommon. We report a rare case of a patient who had metallosis secondary by fibular nonunion after fixation with plate and screw. In addition, we discuss the clinical and the operative findings, as well as the outcome of this uncommon complication.

Cervical spinal stenosis can be diagnosed indirectly by measuring the anteroposterior diameter or Pavlovs ratio in simple cervical spinal radiographs. The purposes of this study were to assess the trasverse areas of the spinal canal,the dural tube and the spinal cord of the cervical spine of normal adults by magnetic resonance imaging (MRI), and to find the possible correlationship among the MRI results. T1-weighted MR images of the cervical spine of 100 normal adults were evaluated by measuring the transverse areas of the three structures in the axial plane. The maximal transverse areas of the spinal cord was 84.5mm2 at C5 and the minimal transverse areas of the dural tube and spinal canal were 153.6mm2 and 232.4mm2 at C6, respectively. The transvere areas of the spinal canal correlated better with the dural tube areas than with the spinal cord areas. The areas of the spinal canal, the dural tube and the spinal cord in MRI correlated better with the sagittal diameter than with the Pavlov's ratio in simple lateral radiographs.

Erythema multiforme can be induced by various causes, including infections like virus or fungus, drugs like sulfonamides and penicillins, internal malignences, connective tissue diseases, pregnancy, menstruation, and exoessive sun exposure ramoxone, one of the paraquat dichloride compounds, is the most commonly used weed-kiIler in Korea. It is sometimes used in suicides due to its fatal toxicity, and even weak transutaneous absorption can lead to death. Herein we report a case of erythema multiform in a 46-year-old man induced by accidental contact with the Gramoxone

Twenty-nail dystrophy is a rare entity in which all 20 nail are uniformly and simultaneously affected with excess longitudinal ridging and loss of luster. This condition is thought to be idiopathic but, many cases are associated with alopecia areata, lichen planus, psoriasis, and ichthyosis. In such cases, it has been hypothesized that immunplogical disorders could play a role in pathogenesis. A 29-year-old male patient presented with dystrophic nail chatge on his all finger and toe nails for 3 years. On phisical examination, all nails were uniformly affected with longitudinal ridging and loss of luster and all body hairs were lost. Thyroid scan showed a finding of chronic thyroiditis. Herein we report a case of twenty-nail dystrophy associated with chronic thyroiditis and alopecia areata.

A case of circular eczematous dermatitis around seborrheic keratosis was presented. A 54-year-old man presented with two weeks history of a round pruritic eruption around a preexisting lesion of seborrheic keratosis. Microscopic findings showed central tumor nest composed mainly of basaloid cells with occasional spongtosis and exocytosis. A diffuse, dense, mononuclear cell infiltrate with increased contents of melanophages was seen beneath the tumor. The surrounding lesion of halo dermatitis showed mild dilatation of the capillaries and perivascular infiltration of mononuclear cells in the upper and mid-dermis. The lesion of halo dermatitis disappeared gradually over a three week period following excision of the central lesion. This peculiar phenomenon seemed to be different from that of Suttons halo nevus, and might be a manifestation of an eczematous condition which might have a dermatitis provoking factor.

Two cases of ectopic kidney were reported in conjunction with review of literatures. The ectopic kidneys, measuring 13 cm-,15 cm in length of their ureter, were located between the L3 .and S1. Operative removal of the ectopic kidney disclosed aberrant arteries in their both pole. histological examination revealed normal findings.
