A 7-year-old girl had a 7 × 6cm sized dark red colored tumor on the left elbow and several erythematous macules on the face, right upper arm, and both thighs. Her general health was good and all laboratory findings were within normal limit. Histopathologic examination revealed an infiltration of atypical mononuclear cells in the dermis and subcutis. L26 and leukocyte common antigen were positively stained in an immunohistochemical study. According to clinical, histological and immunohistochemical findings, we diagnosed the disease as primary cutaneous B cell lymphoma. The patient's skin lesions markedly improved after a surgical excision and chemotherapy.

The effect of a secretory proteinase from the pathogenic amoebae Acanthamoeba castellanii on hosts defense-oriented or regulatory proteins such as immunoglobulins, interleukin-1, and protease inhibitors was investigated. The enzyme was found to degrade secretory immunoglobulin A (sIgA), IgG, and IgM. It also degraded interleukin-1alpha (IL-1alpha) and IL-1beta. Its activity was not inhibited by endogenous protease inhibitors, such as alpha2-macroglobulin, alpha1-trypsin inhibitor, and alpha2-antiplasmin. Furthermore, the enzyme rapidly degraded those endogenous protease inhibitors as well. The degradation of hosts defense-oriented or regulatory proteins by the Acanthamoeba proteinase suggested that the enzyme might be an important virulence factor in the pathogenesis of Acanthamoeba infection.

The use of lower extremity tourniquets for procedures of the lower leg is considered routine in orthopedic surgery, but, lower extremity tourniquets do harm occasionally. While the tourniquet is inflated, metabolic changes such as increased PaCO2 , lactic acid, and serum potassium and decreased level of PaO2 and pH occur in the ischemic limb. Deflation of tourniquet results in release of anaerobic metabolic products during ischemia into systemic circulation. In this ischemia/reperfusion situation, oxygen free radicals could potentially be produced during the reperfusion period by several mechanisms. One of these mechanisms is release of intracellular superoxide or hydrogen peroxide by activated neutrophils in the area. These reactive oxygen species(ROS) could be a causative factor for the postreperfusion no-flow, lung injury, induction of tourniquet shock, etc. The purpose of this clinical study was to investigate the effect of tourniquet deflation on the hemodynamic changes, changes of blood gas analysis, and hydrogen peroxide production using flow cytometric analysis of fluorescent DCF(Dichlorofluorescein). Quantitative analysis of fluorescent DCF was performed in resting and fMLP(N-formyl-methyonyl-leucyl-phenylalanine) or PMA(phorbol myristate acetate) stimulated neutrophils. Also differences of these factors between two groups of tourniquet time, one is less than one hour and the other more than one to two hours, were analysed. The hemodynamics(blood pressure, pulse rate), arterial PO2, bicarbonate, base excess, and hydrogen peroxide production showed no significant change before and after tourniquet release(p>0.05). Arterial pH and PaCO2 decreased significantly until 10 and 5 minutes after tourniquet release, respectively(p>0.05). Tourniquet time didn’t reveal any significances differences. These results indicate that tourniquet application with400mmHg pressure and less than 2 hours does not release significant hydrogen peroxide into systemic circulation during reperfusion period after tourniquet release.

PURPOSE: To evaluate the result of excision and lamellar keratoscleroplasty using ultrasound biomicroscopy in limbal dermoid. METHODS: We retrospectively analyzed in 10 patients with limbal dermoid, who were performed preoperative ultrasound biomicroscopy to access the extent of the lesion and the depth of corneal involvement, and underwent excision and superficial keratoscleroplasty with a minimum follow-up period of 6 months RESULTS: On ultrasound biomicroscopic examination, the dermoid showed highly reflective, homogeneous echo density than surrouding tissue, leading to identifying the lateral margin of the lesion and depth of involvement. The mean maximun thickness of the lesion was 1.1 +/- 0.2mm. The six of 8 patients, who were feasible to test visual acuity, had no change in best corrected visual acuity, and 2 of 8 patients gained less than 1 line. Most patients (9 of 10), except one, had good or excellent cosmetic results with no haze (5 of 10) or minimal haze (4 of 10). CONCLUSIONS: In limbal dermoid, ultrasound biomicroscopy was helpful in accessing the extent of the lesion and the depth of involvement preoperatively, and excision and lamellar keratoscleroplasty leads to good results without complication.

Cutaneous metastases from internal malignancy are relatively rare. Three cases of cutaneous metastases, two from lung cancer and one from breast cancer are reported. Case 1-cutaneous metastasis from bronchioloalveolar carcinoma of the lung, where four erythematous to pinkish pea sized smooth surfaced nodules on the scalp were noticed for 2 years in a 48-year-old man. Case 2-cutaneous metastasis from adenocarcmoma of the lung, where two hard tender freely movable subcutaneous nodules, about 3 cm in diameter on the lateral chest wall were noticed for 6 months in a 61-year-old woman. Case 3-cutaneous metastasis from infiltrating ductal carcinoma of the right breast, where a hand, violaceous, non-tender plaque (8×6.5 cm) on the right areolar area was noticed for 4 months in a 47-year-old woman.

Malignant Atrophic Papulosis*

Leser-Trelat sign is characterized by the sudden appearance and rapid increase in number and size of seborrheic keratoses associated with an internal malignancy. A 78-year-old woman showed multiple pea to bean sized dark brownish papules and plsques on the trunk. Skin lesions had appeared suddenly since 5 months ago and then rapidly increased in number and size. The histopathologic exsmination of the skin lesions revealed seborrheic keratoses. The chest roentgenogram revealed the mass shadow on the right hilar region and transbronchial lung biopsy revealed small cell carcinoma.
