Four cases of extra-osseous osteosarcoma were found among 242 cases recorded as osteosarcoma in the Swedish Cancer Registry during the years 1958 to 1968. The tumours occurred in middle-aged and elderly patients. Three of the tumours were situated in the proximal part of the thigh and one in the scapular region. Histopathologically, all tumours were subclassified as osteoblastic osteosarcomas. ...

Laparoscopic radical nephrectomy has established its role as a standard of care for the management of renal neoplasms. Long term follow-up has demonstrated laparoscopic radical nephrectomy has shorter patient hospitalization and effective cancer control, with no significant difference in survival compared with open radical nephrectomy. For renal masses less than 4cm, partial nephrectomy is indi...

BACKGROUND Extrarenal retroperitoneal angiomyolipomas are rare. AIM To review the literature. RESULTS Angiomyolipomas, previously classified as hamartomas, are now classified as benign tumours. Thirty cases of primary retroperitoneal angiomyolipomas have been reported. Diagnosis of the disease upon is based radiological and pathological findings of triphasic features of (a) fat and (b) bloo...

Background: In fair-skinned Caucasian populations both the incidence and mortality rates of cutaneous melanoma have been increasing over the past decades. With adjuvant therapies still being under investigation, early detection is the only way to improve melanoma patient survival. The influence of incisional biopsies on melanoma patient survival has been discussed for many years. This study inv...

BACKGROUND Excision of the pit of the sinus with phenolisation of the sinus tract and surgical excision are two treatment modalities for patients with sacrococcygeal pilonidal sinus disease. Phenolisation seems to have advantages over local sinus excision as it is performed under local anaesthesia with a relatively small surgical procedure, less postoperative pain, minor risk of surgical site i...

BACKGROUND Local excision of rectal cancer is an attractive option because it avoids the morbidity of radical resection. Concerns have arisen during the past decade, however, regarding substandard oncologic results. OBJECTIVE Using the most recent Survey of Epidemiology and End Results-Medicare data, we examined the change in the use of local excision for rectal cancer from 2000 to 2009 and e...

A simple bone cyst in the upper end of the humerus presents a common surgical problem. lt is usually diagnosed in childhood or adolescence because of a pathological fracture. Rarely the cyst heals after fracture; usually it persists and needs surgical treatment if the risk of recurrent fractures is to be avoided. Curettage of the cyst and packing of the cavity with bone chips is the usual treat...
