Introduction & Objectives: Reconstruction of EXTENSIVE soft tissue defects of ~e is one of the most important problems in plastic surgery. This problem may results from Infections, burns and tumor resection. Reconstruction techniques include: Fasciocutaneous flaps (saphenous, postero lateral thigh), muscular flaps (vastus lateralis, vastus medialis and gastronomies) and free flaps which are the last choice for reconstruction of knee defects. We used lateral and distal thigh flap to cover knee defects in 15 khordad hospital during 1380 to 1382. Material and Methods: During 2 years four patients that suffered from EXTENSIVE soft tissue damage of the knee due to burns were treated. Debridement and primary care were done and defects were covered with gastronomies flaps and with remains of proximal soft tissue defect. Defects were covered by lateral and distal thigh flap. This article reports the analysis and results of this procedure. Results: During this time two patients (17 and 30 years old) were treated by this flap with a mean hospital stay time of 20 days and a mean 15 months of follow up. Conclusions: This flap was used successfully. Usage of this flap for the same conditions is suggested due to an easy technique and a shorter operation time.

Angiofibrom is the most common benign tumor of nasopharynx. Because of site of its origin (Superior border of sphenopalatine foramen), this tumor can extend to nasal cavity, paranasal sinuses, ptrygomaxillary fossa, infratemporal and temporal fossa and Intracranium. The most common symptoms are epistaxis and nasal obstruction. Diagnosis is based on Physical findings and radiology, biopsy may cause fatal bleeding and is avoidedIn a 14 Year old male with a large angiofibroma of nasopharynx, that had extended to nasal cavity (bilaterally), right maxillary sinuse, right ptrygomaxillary and infratemoral fossa, sphenoid sinuse and intracranium (Through parasellar), we prefered to use LefortI osteotomy for removal of the tumor, Because This approach provide an excellent direct access to above regions without facial scarring. This approach for surgery of angiofibroma was Performed for first time in Medical University of Esfahan.

Introduction: One of the most important problem in the construction industry is lack of well sand matters in our country. Due to this reason, EXTENSIVE exploration investigation is necessary to supply parts of society requirement.Aim: The aim of this project is preparing of applied map of sand and Sources to use in industry. Materials and Methods: by using of integrated engineering geology, sedimentology, hydrology and geomorphology data with GIS/RS tecknigues. So all the activities is focused on Mehriz region.Result: According samplings in prospect area and their results, .preparing EXTENSIVE exploration map will be in future plan and finally one type EXTENSIVE exploration map based on necessity in sand and gravel industry was provided.Conclusion: One separated and varied EXTENSIVE exploration map has been provided for civil engineering, geology, sedimentology and hydrogeology experts by sedimentary, GIS and RS data.

Schwannoma is one of the most common benign intracranial tumors, which originates from the Schwann cells of neural structures in the upper part of the vestibular branch of the eighth cranial nerve. This report describes a 64-year-old woman with headache and vertigo who had a past surgical history of acoustic schwannoma about 10 years ago. The patient underwent excisional surgery. Histological examinations revealed schwannoma with EXTENSIVE xanthomatous changes. Immunohistochemistry staining confirmed the diagnosis. Base on the diagnosis, the patient received no more treatment. After 6 months of close follow-up examinations, no recurrence and complication were observed. Schwannoma could be seen with a vast variety of histologic changes. Recurrence of Schownnoma is uncommon in patients without neurofibromatosis, but it should be considered in a proper clinical context.

Introduction: Odontogenic keratocyst (OKC) is an epithelial-derived odontogenic cyst. WHO classified OKC as an odontogenic keratocyst tumor (KCOT) due to its neoplastic nature. OKC is the third most common jaw cyst, usually with no clinical symptoms. Due to its high recurrence rate, correct diagnosis and appropriate treatment plan are essential.Case presentation: This report presents three KCOT cases with bony expansion and relatively variable clinical findings.Conclusion: The most significant lesions in the differential diagnosis of OKC are dentigerous cysts, odontogenic myxoma, ameloblastoma and simple bone cyst. Due to differences in the treatment plans of these lesions, and since they are treated in a more limited manner, exact evaluation of these lesions from clinical, radiographic and histopathologic viewpoints is very important, with significant effects on the therapeutic procedure and recurrence of the lesion.

Overlap syndrome is defined as presentation of a combination of two or more connective tissue diseases in one patient .Herein; we present a 34 years old lady with previous diagnosis of rheumatoid arthritis referring to us with dyspnea on exertion and some other subtle features of systemic lupus erythematous, systemic scleroderma and dermatomyositis. Her HRCT showed diffuse ground glass appearance in both lung fields, typical of alveolitis. She showed dramatic response to multiple pulse steriod therapy with resolution of her pulmonary and extra-pulmonary symptoms.

Background: Mongolian spots are benign skin markings at birth which fade and disappear as the child grows. Often persistent EXTENSIVE Mongolian spots are associated with inborn error of metabolism. We report thirteen people of the single family manifested with EXTENSIVE Mongolian spots showing autosomal dominant inheritance.Case Presentation: A one day old female child, product of second degree consanguineous marriage, born by normal vaginal delivery with history of meconium stained amniotic fluid and birth asphyxia. On examination the child showed EXTENSIVE bluish discoloration of the body involving trunk and extremities in both anterior and posterior aspects associated with bluish discoloration of the tongue. A detailed family history revealed most of the family members manifested with EXTENSIVE bluish discoloration of the body soon after birth which faded in the first few years of life and completely disappeared by puberty. Thus it was diagnosed to be EXTENSIVE Mongolian spots with an autosomal dominant inheritance.Conclusion: Knowledge about the natural history of EXTENSIVE Mongolian spots, their inheritance and association with certain metabolic diseases mainly IEM and Mucopolysaccharidosis aids in the diagnosis and in order to improve the patient’s prognosis.

Becker's naevus shows itself as a pigmented area of skin which is aquired , persistant and asymmetrical and sometimes shows evidence of increased androgen sensitivity. Colocalization with other developmental anomalies is reported rarely.We report a 20 year old woman who developed an EXTENSIVE and bilateral Becker naevus since the age of 12 year and had left breast hypoplasia, too.
