Giant cell tumor is a benign locally aggressive tumor. The standard treatment is en bloc resection followed by major reconstructive surgery, or extended curettage conjunction with bone grafting or the use of bone cement implantations. Surgical treatment of giant cell tumor at the sacrum is associated with high morbidity, and local recurrence. The authors present a case of giant cell tumor at th...

osteoid osteoma is a unique benign primary bone tumor that may present in the metaphyseal diaphyseal areas of the short tubular bones and has also been reported in the carpal bones. it occurs in the first two decades of life. the classic history is bone pain, often relieved by aspirin. the clinical appearance is local swelling and tenderness. the typical radiographic appearance is very characte...

BACKGROUND The purpose of this study was to explore the significance of resection margin status on local recurrence and survival for early (T1/T2) oral cancer and to determine if the significance of the resection margin varies with the biological aggression of the tumor as determined by pN status. METHODS The influence of resection margin size and local recurrence for 295 patients with pT1/T2...

A low grade fibromyxoid sarcoma is a rare soft tissue tumor that has a tendency to develop in the deep soft tissue of young adults and the potential for local recurrence or distant metastasis. There have been several case reports and sporadic reports in the literature. However, only 1 case has been reported in Korea but without a follow-up result. We describe a 54-year-old female patient with a...

Plexiform fibrohistiocytic tumor is an intermediate malignant tumor situated in superficial soft tissues. It affects children and young adults. The tumor is most commonly located on upper extremities, whereas involvement of back region is rare. Mitotic activity is generally low (~3/10 HPF). It is rare, but it can exhibit aggressive behavior, so total excision with clear surgical margins and lon...

BACKGROUND Surgical resection is a universal component of glioma therapy. Little is known about the postoperative microenvironment due to limited preclinical models. Thus, we sought to develop a glioma resection and recurrence model in syngeneic immune-competent mice to understand how surgical resection influences tumor biology and the local microenvironment. METHODS We genetically engineered...

OBJECTIVE To assess predictors of well-differentiated thyroid cancer (WDTC) persistence/recurrence. DESIGN This was a retrospective chart review of thyroid carcinoma patients seen 1979-2007 in a Boston, Massachusetts-area multispecialty group. Of 1,025 patients, 431 met eligibility criteria. Cox proportional hazards models were used to assess predictors (gender, age, ethnicity, tumor size, su...
