From 1976 to 1991, 34 cases of benign tumors of femoral neck were received in our department and 29 cases were treated surgically with either free bone graft (18 cases) or vascularized bone graft (11 cases). Fibrous dysplasia of bone and bone cyst had a high incidence in this group (75%)and most of the patients were over 30 years old. Because the femoral neck had its own anatomical characteristics and was biomechanically important and in order to accelerate. The graft healing and prevent the occurrence of pathological fracture, the choice of operations should depend on the extent of the lesion, the thickness of the cortical bone of the affected past,and the presence or absence of complications.

Our clinical experiences in reconstruction of the defects from excision of benign tumors with expanded skin flap were reported. Since 1987 we have applied this method 23 cases with satisfactory results. When we decided to use this technique, the expander was placed in a pocket adjacent to a benign tumor planned to be excised. Once the skin flap was expanded fully, the tissue expanders were removed. After excision of the benign tumor, the defect was than be covered with the expanded skin flap. The problems related to treatment were discussed in detail.
Objective To improve the knowledge of pulmonary sclerosing hemangioma ( PSH)especially with bilateral multiple lesions of the lung. Methods The clinical data of 3 cases of PSH ( 1 case with bilateral multiple lesions in the lung) were analyzed, and the related literatures were reviewed. Results All of the 3 cases were females. A 22-year-old female patientwith bilateral multiple nodules in the lungs was complicated with thyroid multiple nodular goiter ( with hypothyroidism) , dysfunctional uterine bleeding ( with anemia) , nodular hyperplasia of the breast, and arteriovenous malformation over forearm. Thoracoscopicbiopsy of left lung and resection of the right pulmonary mass were performed and both the lesions were confirmed as PSH. The clinical manifestations of multiorgan diseases and the presence of PSH suggested Cowden syndrome in this patient. The other 2 cases aged 50 and 53 were asymptomatic with solitary pulmonary nodules identified incidentally. The accessory examinations for malignancies, infections, and autoimmune diseases showed no specific findings. Resection of the lesions were performed by thoracoscopic surgery and thoracotomy respectively, and the histopathological results proved to be PSH. Literature review showed that PSH typically occurred in middle-aged women without clinical symptoms and signs, often presenting as a pulmonary solitary nodule/mass identified incidentally. The differential diagnosis should include peripheral carcinoma, hamartoma, inflammatory pseudotumor and tuberculoma. Multiple PSH, which mainly presented as multiple well-defined nodules /masses of different size in the lungs, was rather rare, but easily confused with metastatic neoplasm. Lung biopsy by surgical operation was a common way to confirm the diagnosis, while FDP-PET and fine needle aspiration biopsy showed some defects. Surgical resection was an effective method of treatment, the residual lesions of multiple PSH should be monitored. Cowden syndrome may be considered if a PSH coexisting with abnormity of multiple organs such as thyoid, breast and vessels. Conclusions PSH should be considered during the differential diagnosis for solitary or multiple nodules /masses in the lung. Surgical biopsy is a common way to confirm the diagnosis. Local excision andnecessary follow-up are effective methods of treatment.
ObjectiveTo investigate the clinical outcomes of resection of mandibular benign tumors and primary reconstruction with autogenous bone graft via an intraoral approach. MethodsFifteen patients with mandibular benign tumors were treated between January 2009 and September 2012. There were 7 males and 8 females, aged from 18 to 45 years (mean, 30 years). The pathological diagnosis identified 11 cases of ameloblastoma, 3 cases of odontogenic keratocyst, and 1 case of odontogenic myxoma. According to the Urken's CRBS (Condyle, Ramus, Body, Symphysis) classification criteria based on the location of the mandibular defect, there were 3 cases of body type (B type), 3 cases of ramus type (R type), and 9 cases of body and ramus type (BR type). The surgeries were performed via an intraoral approach, except 1 patient with the lesion at the level of sigmoid notch via an auxiliary preauricular incision. To fix the bone grafts to the dissected mandibular defects, reconstructive titanium plates were used, either indirectly according to the computer aided design/computer aided manufacturing mandibular models before surgery (9 patients) or directly according to the exposed mandibles during surgery (6 patients). The patients received benign mandibular tumor resection and primary autogenous bone graft reconstruction with free iliac bones (11 cases) or vascularized fibular flaps (4 cases). The mandibular inferior alveolar nerves were preserved in 6 cases. ResultsPrimary healing of incision was obtained in 14 patients, while secondary healing in 1 patient suffering from bone graft infection. All the patients were followed up 1-4 years (mean, 2.5 years). At last follow-up, no patients showed facial nerve damage; occlusion of remaining teeth was similar to preoperative conditions; the chewing function was satisfactory; mouth opening was 30-35 mm (mean, 33 mm); and swallowing and speaking functions were normal. Only slight extraoral scars caused by the auxiliary incision and the transbuccal appliances were observed, and all the patients were satisfied with the facial appearance. Lower lip numbness was relived in patients with preserved inferior alveolar nerves. There was no tumor recurrence during follow-up period. ConclusionThe intraoral approach is a feasible and proper approach for resection of benign mandibular tumors and primary reconstruction with autogenous bone grafts, with the advantages of inconspicuous facial scars, minimum damage to the facial nerve, and expectable aesthetic appearance.
ObjectiveTo investigate the role of local pancreatectomy for benign and low-grade malignant pancreatic tumors.MethodThe clinical data of 45 patients with benign and low-grade malignant pancreatic tumors who underwent local pancreatectomy from January 2014 to June 2019 in Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology were analyzed.ResultsForty-five patients underwent the local enucleation or resection with negative margin. The pathological results showed that there were 17 cases of solid pseudopapilloma, 5 cases of mucinous cystadenoma, 4 cases of serous cystadenoma, 10 cases of islet cell tumor, 5 cases of nonfunctional neuroendocrine tumor, 4 cases of congenital cyst. There were 6 cases of head of pancreas, 26 cases of body of pancreas, 8 cases of tail of pancreas, 5 cases of uncinate process. The tumor was 1.2 to 9.0 cm in diameter with an average of 3.2 cm. Among them, the diameter was more than 5.0 cm in 9 cases. The incidence of pancreatic fistula after operation was 57.8%, 65.4% was grade A fistula, 34.6% was grade B fistula, and no grade C fistula occurred. The incidence of abdominal infection was 13.3%, incidence of abdominal hemorrhage was 6.7%. There was no secondary diabetes mellitus and pancreatic endo- and exocrine dysfunction, and no death case.ConclusionsPancreatic enucleation for benign and low-grade malignant pancreatic tumors after strict preoperative evaluation can effectively preserve the pancreatic endocrine function of patients. Although the incidence of pancreatic fistula is high, it is mostly biochemical fistula, and the incidence of serious complications is low.
Objective To explore the correlation between homocysteine （Hcy） level and the risk of breast cancer，and try to find a new method to reduce the risk factors and benefit for treatment of breast cancer. Methods From January2010 to December 2012， 245 cases of breast cancer （breast cancer group）， 109 cases of benign breast tumor （benign breast tumor group）， and 78 cases of healthy women （healthy control group） in the Sichuan Provincial People’s Hospital， who were in accordance with the inclusion criteria， were analyzed retrospectively. The difference of Hcy level was compared among three groups. Meanwhile the relation between Hcy level and patients’s age， blood glucose， serum creatinine， estrogen receptor （ER）， progesterone receptor （PR）， Ki-67 （%）， tumor diameter， or axillary lymph node status was analyzed.Results ① The Hcy level was significantly different among the breast cancer group， benign breast tumor group， and healthy control group （P＜0.001）. The Hcy level of the breast cancer group was significantly higher than those of the benignbreast tumor group （P＜0.001） or healthy control group （P＜0.001）， but the Hcy level was not significantly different bet-ween the benign breast tumor group and healthy control group （P=0.082） . ② The Hcy levels of different types of the breastcancer （type of Luminal A， Luminal B， Her-2， and triple negative） were significantly higher than those of the benign breast tumor group （except for Her-2 type， P＜0.05） or healthy control group （P＜0.05）. ③Plasma Hcy level of the patients with benign and malignant breast tumor was positively correlated with age （r=0.197， P=0.004） or serum creatinine level （r=0.381， P＜0.001）， but not correlated with blood glucose （r=0.023， P=0.668）. ④Plasma Hcy level of the patients with malignant breast tumor was positively correlated with age （r=0.267， P=0.007） or serum creatinine level （r=0.341， P＜0.001）， but not correlated with blood glucose （r=-0.005， P=0.935）， tumor diameter （r=-0.049， P=0.443）， axillary lymph node status （r=-0.006， P=0.921）， or Ki-67 （%） （rs=-0.029， P=0.650）. Conclusions Plasma Hcy level of breast cancer patient is abnormally elevated， and it may have some relation with the occurrence of breast cancer.
