She describe herein two cases of eccrine spiradenoma. One is an indolent and the other is painful or tender multiple small nodules distributed in a zosteriform pattern. Histopathologically, the encapsulated lobules of the tumor are composed of two types of cells, intensely staining cells and pale staining cells, usually arranged in whorls, cords, and pseudoglands. In the second case, enzyme histochemical staining and electron microscopic examination have been done and are compared with other cases in the literature.

We observed the clinical and histopathologic characteristics of acquired, bilateral nevus of Ota-like macules in each 80 and 23 patients. The results were as follows: 1. All patients were female and the peak age of onset was third decade with an a,verage age of 27.4 years. 2. The colors of lesions were slate, brown, dark brown, and blue black in order of freguency. 3. The lesions were most comrnonly observed in the malar area and alae nasi. 4. Three patients had family history of acquired, bilateral nevus of Ota-like :macules. 5. Histopathologically pigment-bearing cells, bipolar or irregular in shape, were found mostly in the upper- and mid-portion of the dermis. The melanocytes showed weakly positive dopa reaction. 6. In electron microscopic observation, these pigrnent-bearing cells contained many singly dispersed melanosomes in stage 3 and 4 of melanization and wece surrounded by an extracellular sheath.

Fracture dislocation or dislocation of the knee can produce a popliteal artery injury that may be difficult to evaluate clinically. Diagnosis of disruption or thrombosis of the popliteal artery is frequently delayed until the opportunity to salvage the extremity is lost. 22 cases of popliteal artery injury were reviewed from July 1978 to December 1983, associated with severe knee trauma at the Orthopaedic department of Kyung Hee University Hospital, of whom average follow-up for about 52 months. The results obtained were as follows; 1. In all 22 cases, 14 cases (63. 6%) were amputated. The amputation rate was correlated with ischemic time after injury. 2. Resection of all injuried vessels with reconstitution of continuity by the use of an interposed saphenous vein graft is often warrented to avoid tension. 3. All 8 patients, which was managed conservatively, were amputated in all cases(100%). In cases of suspicious popliteal artery injury, early aggressive exploration and obvious microvascular reconstruction should be mandatory. 4. Subperiosteal fibulectomy-fasciotomy should be done routinely immediately after vascular injury. 5. Diagnosis of popliteal artery injury was based on the clinical findings but the capillary filling was not contributary. 6. The use of Doppler flowmeter and emergency arteriography was recognizedtobeanexcellent methods in determination of arterial injury.

The anatomical characteristics of the tibia, which is covered by subcutaneous tissue anteriorly, emphasize the vulnerability of the tibia to trauma and frequently result in open comminuted fracture. Open fractures add to the risk of infection and nonunion and require treatment that prevent infection, provide skin coverage, and maintaine reasonable fixation during the early healing phase. 50 cases of tibia shaft fractures were reviewed from May 1978 to December 1983, managed with the modified Vidal-Adrey frame of Hoffmann extemal fixator, at the Orthopaedic Department of Kyung Hee University Hospital. The results obtained were as follows; 1. In 50 cases of tibia fractures, 46 cases are open injuries and 43 cases (86.0%) among them were Grade II and IU open fractures. 2. 31 operative procedures were performed for the coverage of soft tissue injury; 13 cases of rotation and cross-leg pedicle flaps were effective aids, but futher good results could be expected with the micmvascular free flap. 3. 17 operative procedures for acceleration of bony union and reconstruction of bone defect were performed. In cases of massive bone defect, vascularized fibular transplantation and free vascularized fibular graft should be employed, and additional bone shortening and electric stimulation would contribute to the enhancement of the bony union process. 4. The mean period of extemal immobilization with the frame was 15.4 weeks and that of bone union was 31.7 weeks. The periods of bone union were markedly delayed in cases of Grade II andIII open fracture than those of closed and Grade I open fractures. 5. Nonunion developed in 17 cases (34.0%); 4 cases in Grade II and 13 cases in Grade III injury. 6. 12 cases of wound infection developed. 7. 12 cases of pin tract infection happened. More careful pin tract management could diminish this troublesome complication.
