BACKGROUND Involvement of adipose-derived stem/progenitor/stromal cells (ASCs) in the development of lipomas has been suggested, but the pathogenesis and pathophysiology of this tumour remain unclear. OBJECTIVES To analyse cellular and transcriptional characteristics of lipoma tissue compared with normal adipose tissue, further to delineate differentiating features. METHODS For lipoma or no...

Lipoma is the most common benign tumour which occurs anywhere in the body where adipose tissue is present which is asymptomatic, slow growing and painless. The lipoma consists of mature adipose tissue and occurs commonly in region of back, shoulder and nape of neck. Adipose tissue also exists in the parotid gland, but lipoma of the parotid gland is rare entity. The incidence of this entity has ...

intracranial lipoma is an uncommon entity. a rare type of tumor in the internal auditory canal (iac) and the cerebellopontine angle (cpa) is lipoma. there are a few case reports in the literature related to intravestibular lipoma. herein, we report a case of lipomas within the cerebellopontine angle and vestibule of the inner ear in a patient with tinnitus and dizziness. the patient was evaluat...

INTRODUCTION Obtaining vascular access is of paramount importance in trauma care. When peripheral venous access is indicated but cannot be obtained, the intraosseous route represents an alternative. The Bone Injection Gun (BIG) is the device used for intraosseous access by the Israeli Defense Force (IDF). The purpose of this study is to assess the success rate of intraosseous access using this ...

PURPOSE OF REVIEW Difficulties to establish a venous access may also occur in routine pediatric anesthesia and lead to hazardous situations. Intraosseous infusion is a well tolerated and reliable but rarely used alternative technique in this setting. RECENT FINDINGS According to recent surveys, severe complications of intraosseous infusion stay a rare event. Minor complications and problems i...

High levels of uric acid cause accumulation of monosodium urate crystals. This formation of masses is called tophus. Intraosseous tophus deposits are rare, even for patients with gout. We report an unusual case of intraosseous tophus deposits in the os trigonum. The patient presented with ankle pain with no previous history of gout. On examination, tenderness on the posterior aspect of his ankl...

lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. some studies show that less than 1% of lipomas were ossified. we describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. to the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and h...

Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw occurring most commonly in mandibular ramus molar area with male predilection. Peripheral KCOTs are very uncommon. Here we report a case of keratocyst in buccal mucosa in a 55 years old female patient, the diagnosis of which was based on subjective histological evaluation and further confirmed by immunohistochemi...

schwannoma(neurilemmoma) is a benign tumor originates from schwann cells. ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. the mandible is the most common site of occurrence for this lesion. we report a rare case of intraosseous ancient schwa...

BACKGROUND This study was conducted to examine the clinical usefulness and efficacy of endoscopic curettage on benign bone tumor. METHODS Thirty-two patients (20 men and 12 women) with benign bone tumor were included in the study. The patients were aged between five and 76 years; the mean follow-up period was 27.05 months (range, 9.6 to 39.9 months). The primary sites include simple bone cyst...
