Short-Term Walking Outcomes in Diabetic and NonDiabetic Unilateral Transtibial Amputees

This study compared short-term walking outcomes in diabetic amputees after prosthesis fitting compared to that in non-diabetic amputees. We retrospectively investigated walking outcomes at 3 months after starting gait training with a prosthesis. Forty-four unilateral transtibial amputees with (n=18) and without diabetes (n=26) were included. At 3 months after gait training with a prosthesis, only 2/18 (11.1%) and 3/18 (16.7%) diabetic amputees were capable of independent outdoor and indoor walking without cane, respectively. However, 21/26 (80.8%) and 24/26 (92.3%) non-diabetic amputees were capable of independent outdoor and indoor walking without cane, respectively. With assistance of cane, most of non-diabetic amputees (n=24, 92.3%) were capable of walking in both outdoor and indoor but only seven (38.9%) and nine (50.0%) diabetic amputees were capable, respectively.Thus, short-term walking outcome were poor in transtibial amputee with diabetes compare to those without diabetes, and these results suggest intensive rehabilitation would be needed to them.

Effects of the 2008 Global Economic Crisis on National Health Indicators: Results from the Korean National Health and Nutrition Examination Survey / 가정의학회지

BACKGROUND: The relationship between economics and health has been of great interest throughout the years. The accumulated data is not sufficient enough to carry out long-term studies from the viewpoint of morbidity, although Korea National Health and Nutrition Examination Survey (KNHANES) was carried out yearly since 1998 in Korea. Thus, we investigated the effect of the 2008 global economic crisis on health indicators of Korea. METHODS: Health indicators were selected by paired t-test based on 2007 and 2009 KNHANES data. Age, gender, body mass index (BMI), smoking, drinking, exercise, education, income, working status, and stress were used as confounding factors, which were analyzed with logistic and probit analyses. Validation was done by comparing gross domestic product (GDP) growth rates and probit analyses results of 2007-2012 KNHANES data. RESULTS: Among several health indicators, the prevalence of hypertension and stress perception was higher after the economic crisis. Factors related with higher hypertension prevalence include older age, male gender, higher BMI, no current tobacco use, recent drinking, lower education levels, and stress perception. Factors related with more stress perception were younger age, female gender, current smoking, lower education levels, and lower income. GDP growth rates, a macroeconomic indicator, are inversely associated with hypertension prevalence with a one-year lag, and also inversely associated with stress perception without time lag. CONCLUSION: The economic crisis increased the prevalence of hypertension and stress perception. In the case of GDP growth rate change, hypertension was an inversely lagging indicator and stress perception was an inversely-related coincident indicator.

The Effect of Platelet Rich Plasma from Bone Marrow Aspirate with Added Bone Morphogenetic Protein-2 on the Achilles Tendon-Bone Junction in Rabbits

BACKGROUND: To determine if exogenously injected bone marrow derived platelet-rich plasma (PRP) plus bone morphogenetic protein (BMP)-2 could accelerate the healing of bone-tendon junction injuries and increase the junction holding strength during the early regeneration period. METHODS: A direct injury model of the bone-tendon junction was made using an Achilles tendon-calcaneus bone junction in a rabbit. In the PRP/BMP-2/fibrin group, 0.05 mL of bone marrow derived PRP and 100 ng/mL of BMP-2 both incorporated into 0.1 mL of fibrin glue were injected into Achilles tendon-calcaneus bone junctions. The effect of the intervention was tested by comparing the results of an intervention group to a control group. The results of biomechanical testing, and histological and gross analyses were compared between the 2 groups at the following time points after surgery: 2 weeks, 4 weeks, and 8 weeks. RESULTS: Histologic examinations showed that woven bone developed in tendon-bone junctions at 2 weeks after surgery in the PRP/BMP-2/fibrin group. Mechanical test results showed no significant difference between the PRP/BMP-2/fibrin and control groups at 2 and 4 weeks after surgery, but the mean maximal load in the PRP/BMP-2/fibrin group was significantly higher than in the control group (p < 0.05) at 8 weeks after surgery. CONCLUSIONS: Bone marrow derived PRP and BMP-2 in fibrin glue accelerated healing in a rabbit model of tendon-bone junction injury.

Changes in Level of the Conus after Corrective Surgery for Scoliosis: MRI-Based Preliminary Study in 31 Patients

BACKGROUND: Detection of postoperative spinal cord level change can provide basic information about the spinal cord status, and electrophysiological studies regarding this point should be conducted in the future. METHODS: To determine the changes in the spinal cord level postoperatively and the possible associated factors, we prospectively studied 31 patients with scoliosis. All the patients underwent correction and posterior fusion using pedicle screws and rods between January 2008 and March 2009. The pre- and postoperative conus medullaris levels were determined by matching the axial magnetic resonance image to the sagittal scout image. The patients were divided according to the change in the postoperative conus medullaris level. The change group was defined as the patients who showed a change of more than one divided section in the vertebral column postoperatively, and the parameters of the change and non-change groups were compared. RESULTS: The mean pre- and postoperative Cobb's angle of the coronal curve was 76.80degrees +/- 17.19degrees and 33.23degrees +/- 14.39degrees, respectively. Eleven of 31 patients showed a lower conus medullaris level postoperatively. There were no differences in the pre- and postoperative magnitude of the coronal curve, lordosis and kyphosis between the groups. However, the postoperative degrees of correction of the coronal curve and lumbar lordosis were higher in the change group. There were also differences in the disease entities between the groups. A higher percentage of patients with Duchene muscular dystrophy had a change in level compared to that of the patients with cerebral palsy (83.3% vs. 45.5%, respectively). CONCLUSIONS: The conus medullaris level changed postoperatively in the patients with severe scoliosis. Overall, the postoperative degree of correction of the coronal curve was higher in the change group than that in the non-change group. The degrees of correction of the coronal curve and lumbar lordosis were related to the spinal cord level change after scoliosis correction.

Analysis of failed arterial embolization for postpartum hemorrhage / 대한산부인과학회지

OBJECTIVE: To investigate what factors are associated with a failed arterial embolization for postpartum hemorrhage (PPH) and to attempt to estimate efficacy of arterial embolization. METHODS: Between 2004 and 2008, 60 patients at Korea University Medical Cencter underwent arterial embolization to control obstetrical hemorrhage. In all cases, arterial embolization was performed because of intractable hemorrhage unresponsive to conservative management. Medical records and angiographic results were reviewed. Arterial embolization failure was defined as the requirement for subsequent surgical procedure to control PPH with the procedure, and its results. RESULTS: Arterial embolization was attempted in 60 of deliveries. Failures occurred in 7 of 60 cases (11.7%) and in 4 of 7 cases (57.1%) of abnormal placentation (placenta previa totalis with or without placenta accrete or increta). Comparison of the failed and successful arterial embolization groups showed no differences in maternal characteristics, clinical status, and angiographic finding. Amount of total transfusion in failed arterial embolization group were larger than successful group although hemoglobin before embolization was not different. CONCLUSION: The only factor significantly associated with failed arterial embolization was an abnormal placentation. Arterial embolization is a safe and highly effective method to control PPH.

2-5 Year Results of the Cemented Polished Versys Heritage(R) Femoral Stem / 대한정형외과학회잡지

PURPOSE: Surface finishing of a cemented femoral stem is a subject of controversy even though contemporary cementing techniques have improved results. Versys Heritage femoral stem was used with a contemporary cementing technique to determine the outcome of using a polished surface. MATERIALS AND METHODS: Between October 2000 and August 2003, 131 primary hybrid hip arthroplasty procedures were performed in 117 patients. The mean age at the time of the index arthroplasty was 52 years and 9 months (24-78 years). The average follow up period was 49 months (range, 24-71 months). All the hips were evaluated clinically by the Harris hip score and radiologically by the cement grade, osteolysis as well as stress shielding. RESULTS: At the final follow up, the Harris hip score for all patients had improved from preoperative 59.1 (range, 17-91) to post operative 92.8 (range, 78-100). The cement grade was measured using Barrack's method. Of 131 hips, 75, 54 and 2 were grade A, grade B and grade C1 at the final follow up, respectively. None of the hips showed a C2 or D grade. There was no evidence of aseptic loosening or osteolysis on the femoral side during follow up. 45% of stems showed grade 1 and 2 stress shielding according to Engh's criteria. CONCLUSION: In this study, the Polished Versys Heritage femoral stem(R) showed excellent results at the short to mid term follow up period. However, a longer-term follow-up study will be needed to clarify the implications of the femoral prosthesis surface finish or design.

Comparison of LC-DCP versus LCP for Internal Fixation of Humeral Shaft Fractures in Elderly Patient

PURPOSE: To compare outcomes of humeral shaft fractures fixed with locking compression plate and those fixed with dynamic compression plate in elderly patients. MATERIALS AND METHODS: Nineteen consecutive elderly patients with a fracture of the humeral diaphysis were evaluated retrospectively. Ten patients had been fixed with LC-DCP, and nine had been fixed with LCP. Radiological and clinical results were compared and comparison of implants was done. RESULTS: Loosening of the plate occurred in one case each from the LCP group and the LC-DCP group. The rest of the patients achieved union uneventfully without any complications. Union rate, clinical score and hardware were not significantly different between the two groups. One patient who developed loosening in the LC DCP underwent reoperation whereas one patient with loosening in the LCP was successfully managed conservatively. CONCLUSION: Principle of fracture fixation was more important than plate selection in humeral shaft fracture of elderly patient.

Treatment of Pelvic Osteolysis with a stable Cementless Acetabular Cup with Exchange of Polyethlene Liner and Morselized Bone Graft

Purpose: We evaluated, retrospectively, twenty hips that had undergone revision surgeries because of massive pelvic osteolysis in order to determine the retention rate of acetabular metal shells and polyethylene liner exchanges.. Materials and Methods: We performed liner exchanges for massive osteolysis around stable HG acetabular cups with severe polyethylene wear in twenty-three hips, between June 1996 and May 2003. Clinical and radiological follow-up was available for 20 hips for more than 2 years. In 18 hips, we performed curettage of the granulomatous tissue and tightly packed morselized cancellous allografts into the screw holes or the peripheral rims for the acetabular osteolytic lesions. The mean follow-up period was 3.8 years (range, 2.4 to 9.3 years) and the mean of time from the primary total hip arthroplasties to the component exchanges, was 8.2 years (range, 5.6 to 12.4 years). Results: During the follow-up period, all of the hips were functioning well, and none required any subsequent repeat surgeries. Dislocations occurred three times after the repeat operations in one hip, which was treated successfully with an abduction brace. None of the hips demonstrated a progression of the pre-existing osteolytic lesions or the development of any new osteolytic lesions. At the final follow-up, none of the acetabular components demonstrated any evidence of loosening. Conclusion: Our results demonstrated that isolated liner exchanges and debridement of the granulomatous tissue, with or without bone grafting, can be an effective alternative solution to revision of the cup for massive osteolysis around well-fixed, cementless, acetabular cups in selected patients. Retention of the pre-existing cementless acetabular cup provides less intra-operative and post-operative morbidity. However, in order to determine the longevity of the retained cementless acetabular cups, further long-term studies are necessary.

Clinical application of serum CA 125 and CA 19-9 in Endometriosis / 대한산부인과학회지

OBJECTIVE: The aim of the present study was to investigate the clinical usefulness of serum CA 125 and CA 19-9 levels for diagnosing and determining the severity of endometriosis. METHODS: A total of 112 women who underwent gynecologic surgery between January 1998 and August 2004 were selected in this study. 81 patients had histologically confirmed endometriosis and the remaining 31 had benign ovarian tumor but no obvious evidence of endometriosis. Blood samples were collected in all patients before the operation and the mean values and standard deviations of both serum CA 125 and CA 19-9 levels were measured in various stages of disease. Both tumor markers were also measured in the control group. The results were compared to determine the usefulness of CA 125 and CA 19-9 in diagnosing and predicting the severity of endometriosis. As a results, new cutoff values of serum CA 125 and CA 19-9 in endometriosis were obtained. RESULTS: The mean levels of serum CA 125 and CA 19-9 in patients at stage III and IV of endometriosis were significantly higher than in patients without endometriosis, and increased in accordance with the advancement of the clinical stage. Statistically appropriate cutoff values of CA 125 and CA 19-9 were calculated to be 20 IU/mL and 10 IU/mL, respectively. The sensitivity and specificity of CA 125 at this cutoff value for endometriosis were 72% and 71%, respectively. The sensitivity and specificity were 59% and 55% respectively in the case of CA 19-9. CONCLUSION: CA 125 is a useful marker for diagnosing and determining the severity of endometriosis. CA 19-9 shows limitation in diagnosing endometriosis, but is indeed a potential marker in predicting the severity of disease.

Agenesis of corpus callosum prenatally diagnosed with fetal MRI: case report / 대한산부인과학회지

Agenesis of corpus callosum is the cerebral malformations whose prognosis is uncertain. But the complete agenesis shows more poor prognosis than partial agenesis. So, the type of agenesis can affect significantly the antepartum management. Recently, there has been a development in diagnostic tools like MRI to overcome these limitations of antenatal ultrasonography. We report a case of agenesis of corpus callosum which was diagnosed by prenatal MRI. This case was confused with Dandy-Walker complex in prenatal ultrasonography and supported in diagnosis by prental MRI.

Maternal Circulating Vascular Endothelial Growth Factor in Normal Pregnancies and their Relationship to Platelet Counts / 대한산부인과학회잡지

OBJECTIVE: The aim of the present study was to evaluate changes of vascular endothelial growth factor levels in maternal circulating blood during normal pregnancies and examine their relationship with maternal platelet counts. METHODS: The 33 subjects were selected from healthy normotensive women from the antenatal clinic at Korea University Medical Center, Guro Hospital. Blood samples for VEGF were taken at 7 to 8 weeks' gestation, 16 to 18 weeks' gestation, 24 to 26 weeks' gestation, 30 to 32 weeks' gestation, 37 to 41 weeks' gestation. Serum and plasma were extracted from all samples, and VEGF concentrations were measured in duplicates by competitive enzyme immunoassay. The 23 of them, the platelet counts were performed with an automated blood Coulter counter. RESULTS: Serum VEGF levels during normal pregnancies were mean 6.73 ng/mL at 7-8 weeks' gestation, 7.88 ng/mL at 16-18 weeks' gestation, 7.18 ng/mL at 24-26 weeks' gestation, 8.42 ng/mL at 30-32 weeks' gestation, 14.03 ng/mL at 37-41 weeks' gestation. Plasma VEGF levels were mean 5.50 ng/ mL at 7-8 weeks' gestation, 7.23 ng/mL at 16-18 weeks' gestation, 7.98 ng/mL at 24-26 weeks' gestation, 7.35 ng/mL at 30-32 weeks' gestation, 14.05 ng/mL at 37-41 weeks' gestation. The trends in the mean VEGF levels were similar between serum and plasma, with stable levels until 30 to 32 weeks' gestation, and then the levels were increased. There was no significant difference between serum VEGF levels and plasma VEGF levels (p=0.236) and no correlation between circulating VEGF levels and platelet counts. CONCLUSION: Our data suggests that platelets may not be the origin of elevated VEGF levels in normal pregnancies because there was no correlation between VEGF levels and platelet counts.

Comparison of the Results of Core Decompression and Sugioka's Transtrochanteric Rotational Osteotomy for Osteonecrosis of the Femoral Head / 대한정형외과학회잡지

PURPOSE: This study conducted a comparative analysis on 49 hips treated with a core decompression procedure and 19 hips treated with a Sugioka's transtrochanteric rotational osteotomy for a osteonecrosis of the femoral head (ONFH). MATERIALS AND METHODS: This study evaluated the relationship between the Ficat and Arlet Stage and the extent of the necrotic lesion (using Shimizu's Grade Classification), and the clinical outcome of each procedure. The patient's outcomes were assessed after a mean follow-up of 46 months (range=36-82 months) after the core decompression and 53 months (range=37-108 months) after the Sugioka's transtrochanteric rotational osteotomy. The results were considered successful if the patients were asymptomatic with no disease progression, and unsuccessful if there was radiographic (progression of the stage or collapse) or clinical failure (the need for an arthroplasty or subsequent salvage operation). RESULTS: Twenty one out of 49 cases (43%) in the core decompression group and 14 out of 19 (74%) in the rotational osteotomy group showed successful outcomes. In the core decompression group, among the 22 F-A Stage I hips, 15 (68%) hips had survived according to radiological criteria. All four (100%) Shimizu's Grade A hips of the F-A Stage I had successful results, which is in contrast to the 11 hips out of 18 hips (61%) of the Shimizu's Grade B and C hips (p<0.01). Six (38%) out of 16 F-A Stage IIA hips and two (25%) out of eight IIB hips in the core decompression group had successful results, while 11 (85%) out of 13 IIA and two (50%) out of four stage IIB hips in the rotational osteotomy group had successful results. In the F-A Stage III hips, all 2 hips in the Sugioka transtrochanteric rotational osteotomy treatment group had survived, while none of the three Shimizu's Grade C hips in the core decompression group were successful. CONCLUSION: A core decompression is effective only in the earliest stages of osteonecrosis (F-A Stage I), which means that its success strongly depends on the location and extent of the femoral head necrosis. Sugioka's transtrochanteric rotational osteotomy is a more dependable procedure than a core decompression for treating large lesions of nonsteroidal ONFH, particularly for patients under the age of 50.

Relationship of Risser Sign with Chronological Age, Menarche in Elementary, Middle, and High School Students in Korea / 대한정형외과학회잡지

PURPOSE: This study was undertaken to investigate the relationship between the Risser sign and chronological age and menarche in elementary, middle, and high school students, and to investigate the reliability of the Risser sign. MATERIALS AND METHODS: We reviewed 1, 870 spine standing AP X-rays, which included the iliac crest. We tried to identify a correlationbetween the Risser stage and chronological age, and between Risser stage and menarche. In addition, we investigated inter-observer error in the determination of Risser stage. RESULTS AND CONCLUSION: The mean ages of Risser 1, 2, 3 and 4 female students were 12.9, 13.3, 13.6, and 14.3 years, and the mean ages of Risser 1, 2, 3 and 4 male students were 14.0, 14.3, 14.5, and 15.6 years (Spearman's rho=0.560, p<0.01). The mean menarchal age of female students were 12 years 4 months, which is 7 months earlier than the mean chronological age of Risser 1 in female students. Wefound that it takes 24 months to progress from menarche to iliac crest maturation (Risser 4) (Spearman's rho=0.571, p<0.01). The percentage of agreement in the determination of Risser stage by three orthopaedic surgeons was 73.3%, showing good reliability with a Kappa value of 0.739-0.783.

A Case of Intramural Pregnancy

Intramural pregnancy is a rare variant of ectopic pregnancy, which was first reported in 1924 by Perli, and only 21 cases have been reported in the literature. The pathologic diagnosis of an intramural pregnancy can be made by the myometrium surrounding the products of conception that separate it from the endometrial cavity or fallopian tubes. Recent development of radiologic ultrasonography and radioimmunoassay of the beta-subunit of human chorionic gonadotropin has markedly enhanced the ability to diagnose intramural pregnancy during very early gestation. Many reports have noted that there would be possible relationships between the intramural pregnancy and prior uterine traumatic factor-curettage, cesarean section, myomectomy, salpingectomy, and manual removal of the placenta. We experienced a 28-year-old female patient with amenorrhea for 7 weeks and sudden vaginal spotting. She underwent dilatation and curettage at 4 weeks of gestation. We report this case with a brief review of the literature.

Asymmetric Exercise and Scoliosis: A Study of Volleyball Athletes / 대한정형외과학회잡지

PURPOSE: To determine the prevalence of scoliosis in volleyball athletes and compare this with the prevalence in the general population. MATERIALS AND METHODS: One hundred and sixteen volleyball athletes who had been enrolled in the activity for more than one year were examined for prevalence of scoliosis. The Adams forward bending test was performed with a measurement of the truncal asymmetry using a scoliometer (Orthopaedic System, Inc, USA). Those atheletes who showed more than 5degreesof measurement were selected for an X-ray evaluation. Data from a randomized point prevalence survey of Korean Middle school students (46,428) in Seoul City, which had been performed by our department, was adopted for the control group. RESULTS: Among the 116 volleyball players, 60 (51.7%) showed more than a 5degreesof angle of trunk rotation, whereas controls of middle school students showed 2.5%. Cobb's angle more than 10degrees was 6 (5.17%) in athletes and the control group was 465 (1.0%). Despite higher frequency of prevalence, the Cobb' angle was below 15degrees whereas the control group showed a severe scoliosis which of Cobb's angle reaching to 45degrees. CONCLUSION: Volleyball athletes showed a higher incidence of truncal asymmetry and scoliotic spinal columns than the control group. However, we were able to conclude that asymmetrical muscle development can produce a mild scoliosis. However this doesn't have the potential for a severe progression as found in some cases of idiopathic scoliosis.

Idiopathic Scoliosis in Korean Middle School Students: Prevalence study / 대한정형외과학회잡지

PURPOSE: To update and reevaluate the scoliosis prevalence in middle school students in Korea, and correlate those data with past references and other countries general prevalence. MATERIALS AND METHODS: Among the middle schools in Seoul city, forty-five middle schools were randomly selected for screening. Total number of students were 46,428 who were screened for the prevalence of adolescent idiopathic scoliosis. There were 24,892 boys and 21,536 girls. Their age ranged from 12 to 15 years. Adams forward bending test and "Scoliometer" (Orthopaedic Systems, Inc, USA) were used to detect and measure the degree of rotation of trunk. Students more than 5 (ATR were assessed subsequently by standardized clinical and radiological examinations. RESULTS: Using 10 degrees as cut-off points, 465 students were found to have structural idiopathic scoliosis, representing a prevalence of 0.9% overall. CONCLUSION: The prevalence of the scoliosis has not changed from previously estimated rates in Korea, which was about 20 years ago. It nearly approximates with the prevalence of the world wide reported. We also confirmed that it is not necessary to issue a mass screening, considering the cost and effectiveness aspect, due to its low prevalence.

Clinical Usefulness of Alendronate for Osteoporosis in Postmenopausal women / 대한산부인과학회잡지

OBJECTIVE: To evaluate the usefulness of alendronate for prevention and treatment of postmenopausal osteoporosis this study was taken. METHODS: This prospective randomized clinical trial examined the effects of oral alendronate and HRT(conjugated estrogen plus medroxyprogesterone acetate), in combination and seperately, on BMD, biochemical markers of bone turnover in 79 women with low bone mass. Treatment included alendronate(10mg daily) plus HRT(group I, n=38), or HRT(group II, n=41) for 6 months. Bone density measurements were performed at months 0 and 6 at the lumbar spine. Biochemical markers of bone turnover were also measured every three months. RESULTS: Serum Osteocalcin decreased by 19.2% in group I and by 10.0% in group II at 3 months(p<0.05), and by 30.9% in group I and by 19.8% in group II at 6 months(p<0.05). Urinary deoxypyridinoline showed decrease of 19.75%(I) vs. 10.4%(II) at 3 months, 30.1%(I) vs. 20.7%(II) at 6 months, the difference was significant. Percent change of BMD measurements from baseline at 6 months in group I was 6.2% and in group II 0.6% on the lumbar spine(p<0.05). CONCLUSION: The treatment with alendronate is useful to postmenopausal women with osteoporosis by decreasing bone turnover markers, and by increasing the BMD.

Management of Post-Pneumonectomy Empyema / 대한흉부외과학회지

BACKGROUND: Post-pneumonectomy empyema(PPE) is an uncommon but a serious complication. The management remains as challenge for general thoracic surgeons. MATERIAL AND METHOD: During the period of January 1990 to December 1996, we evaluated the results of 20 patients with post-pneumonectomy empyema. RESULT: Sex ratio were 15 male and 5 female patients with mean age of 41.5+/-21.5 yrs. The occurrence ratio of left to right side was 8:12. The most common disease for prior pneumonectomy was pulmonary tuberculosis. The duration between pneumonectomy and PPE was variable in 1 month to 6yrs. Fever was the most frequent symptom and S. aureus was the most frequent pathogen. In 13 cases, there were combined with BPF. Four patients underwent trans-sternal closure, and Clagett procedure was performed. There was one recurrence that later underwent muscle plombage and omentopexy later. Nine patients underwent omentopexy, muscle plombage and thoracoplasty. There were 7 cases that were not combined with BPF. All 7 patients underwent thoracoplasty, and two of them were combined with muscle plombage. Mean follow-up duration is 40+/-32.3 months. There were no late deaths nor recurrences of PPE. CONCLUSION: We conclude that early diagnosis and proper drainage in PPE patients are important in its initial stage of management, and also management is completely achieved in thoracoplasty with muscle plombage or omentopexy.

Pulmonary Mucinous Cystic Tumor of Borderline Malignancy: A case of report / 대한흉부외과학회지

Pulmonary mucinous cystic tumor of borderline malignancy is very rare and distinguished from bronchogenic cyst or adenocarcinoma of bronchoalveolar type. We present the case of a 63-year-old woman with a right lower lobe mass, found by chest radiographs. The preoperative diagnosis was made as bronchoalveolar cancer by percutaneous needle aspiration of mass. Right lower lobectomy and lymph node dissections were performed. The lobectomy specimen contained variable sized multilocular cystic mucous masses, filled with mucus. Microscopically, the cystic masses are lined with tall columnar mucinous epithelium but some area contains focal cellular atypism and bronchoalveolar cancer like foci. This foci are lack of cellular atypism consistent with bronchoalveolar cancer cell. After lobectomy the patient has remained free from recurrence and distant metastasis for following 12 months period. Pulmonary mucinous cystic tumor of borderline malignancy appears to have a favorable prognosis and should be distinguished from other lung neoplasms.
