OBJECTIVETo initially explore the clinical effect of cool-tip radiofrequency ablation combined with enucleation for the giant hamartoma of kidney with narrow base and export-oriented way of growth.

METHODSThe clinical date of 15 patients including 6 male and 9 female with special hamartoma of kidney underwent cool-tip radiofrequency ablation assisted enucleation from July 2011 to October 2014 were reviewed.The median age was 49 years (ranging from 35 to 71 years). There were 6 cases with left renal tumor, 8 cases with right renal tumor and 1 case with solitary kidney tumor.All patients were confirmed by B ultrasound or CT scan, the mean diameter of hamartoma of kidney was 9.7 cm(8.5-12.7)cm, all tumors were located distant from the collecting system and presents with a special way of growth.The preoperative hemoglobin was (129±18)g/L, SCr was (92±41)μmol/L, glomerular filtration rate (GFR) was (32±12)ml·min(-1)·1.73 m(-2).

RESULTSCool-tip radiofrequency ablation assisted enucleation was technically successful in all patients.The mean operative duration was (115±31)minutes, and the average intraoperative bleeding was (72±21)ml with no blooding transfusion.The postoperative hospital stay was(7±2)days, and the postoperative hemoglobin was(129±18)g/L, SCr (92±41)μmol/L, GFR(30±15)ml·min(-1)·1.73 m(-2). No statistic change of hemoglobin and SCr or glomerular filtration rate after operations(all P>0.05). Postoperative pathology showed that all cases were hamartoma of kidney.During a mean follow-up period of 19.5 months, none of them had local tumor recurrence or chronic renal insufficiency.

CONCLUSIONSCool-tip radiofrequency ablation assisted enucleation is both safe and effective in the treatment of huge hamartoma of kidney with a narrow base and export-oriented way of growth. The short-term follow-up shows a satisfactory therapeutic effect.

A 50-year-old Chinese man presented with abdominal pain associated with bloody mucoid stools, loss of appetite and weight loss. Contrast-enhanced computed tomography of the abdomen and pelvis revealed a colocolic intussusception secondary to a lipoma. The patient subsequently underwent a left hemicolectomy. Clinical and imaging findings of intussusception in adults are discussed in this article.

OBJECTIVE: To investigate the clinical and pathological features of solitary pterygoid benign lesions, as well as the treatment and outcome of endoscopic surgery. METHOD: We retrospectively analyzed clinical data of 4 patients with pterygoid benign lesions in our department. High resolution CT and enhanced MRI were performed before the operations, then endoscopic surgeries were carried out under the circumstance of general anesthesia. After a follow-up in 12 months to 48 months, nasal endoscopy and MRI examination were performed. Therefore we are able to understand the situation of operations and postoperative recurrences, and to inquire about the changes of symptoms and the relief of symptoms before and after surgery. RESULT: From the Pathological diagnosis, it showed 2 cases of cystic lesions, 1 case of spindle cell lipoma, 1 case of inflammatory lesion. Postoperative follow up showed scar formation, smooth surface, no recurrence, and no new symptom. Nasal obstruction is relieved after the surgery, and no changes in the sympotoms of headache were observed. CONCLUSION The combination of high resolution CT with enhanced MRI isimportant for ascertaining the location, extent and nature of the pterygoid lesions. Endoscopic surgery is a minimally invasive, safe, and effective method for the treatment of solitary pterygoid benign lesions.

The patient, female, 27 years old. The scalp neoplasm had been found at her right temple 10 years ago. At first, the size of the tumor was just like a soybean, and did not grow obviously in the past nine and a half years. But the tumor increased fast in these six months, almost as large as the pigeon egg now. The physical examination showed that: A spherical tumor locates in the right temple near the right ear; the size of the tumor is 3 cm X 4 cm X 3 cm; the surface is smooth, no tenderness, no obvious mobile base, skull defect not touched. Primary diagnosis: the scalp cyst or lipoma. Under the local anesthesia we remove the neoplasm, during the operation we found the lesion located in the subcutaneous tissue layer, involved the galea aponeurosis layer, the skull surface are smooth and complete. The tumor was completely removed. We cut the mass and found a cystic cavity sized 3 cmX4 cm, which contained gray jerry-built materials, contained oil and a mass of hair, the capsule wall was complete. Postoperative pathological report: The tumor is cystic look throught the microscope, the capsule wall is squamous epithelium, containing keratinized material and hair. The pathological diagnosis is teratoma. The incision healed primarily, no recurrence found for about a year.

We reported a case of children's OSAHS caused by the huge fibrolipoma in pharynx nasalis. The patient was a 10-years-old child who went to the hospital with the chief complaint of "Snoring and mouth breathing during sleep for 10 years". Imaging tests found one huge tumor in pharynx nasalis before the operation. The tumor was resected totally. The postoperative pathological diagnosis was fibrolipoma. No recurrence was noted during the follow-up visit one year postoperatively. The clinical features, diagnosis, treatment, pathology and prognosis were reviewed herein.

Lipomas are common benign tumors of mature adipose tissue, enclosed by thin fibrous capsules. They can occur on any part of the body; however, peritoneal lipoma is extremely rare. We encountered a case of a 75-year-old man presenting with intermittent abdominal pain, who had undergone right hemicolectomy due to colon cancer. Abdominal computerized tomography showed a well-defined heterogenous fatty mass measuring 4.5x3.5 cm in size, suggesting fat necrosis located in the abdominal wall. Laparotomy showed a very large soft mass of peritoneum. Pathologically, the tumor was diagnosed as lipoma containing fat necrosis located in parietal peritoneum not fixed to any organs, but with small bowel adhesion. Due to its rare etiologic origin and obscure cause of development, we report on a case of lipoma of parietal peritoneum causing abdominal pain.

The cerebello-pontine angle lipomas causing trigeminal neuralgia or hemifacial spasm are rare. A lipoma causing glossopharyngel neuralgia is also very rare. A 46-year-old woman complained of 2-year history of severe right throat pain, with ipsilateral episodic otalgic pain. The throat pain was described as an episodic lancinating character confined to the throat. Computed tomography and magnetic resonance imaging revealed a suspicious offending posterior inferior cerebellar artery (PICA) compressing lower cranial nerves including glossopharyngeal nerve. At surgery, a soft, yellowish mass (2x3x3 mm in size) was found incorporating the lateral aspect of proximal portion of 9th and 10th cranial nerves. Only microvascular decompression of the offending PICA was performed. Additional procedure was not performed. Her severe lancinating pain remained unchanged, immediate postoperatively. The neuralgic pain disappeared over a period of several weeks. In this particular patient with a fatty neurovascular lump causing glossopharyngeal neuralgia, microvascular decompression of offending vessel alone was enough to control the neuralgic pain.
