Maxilla And Mandible

Ameloblastomas arising in the supraperiosteal soft tissues (peripheral ameloblastoma) and those taking origin in the maxilla have distinctively different biologic behaviors. The peripheral ameloblastoma can be successfully treated by conservative excision while en bloc resection is warranted for the maxillary ameloblastoma. The effectiveness of primary surgical treatment of an ameloblastoma of the maxilla is the key to reduce morbidity and mortality from the lesion. Anatomic differences between the maxilla and mandible and an apparent more aggressive behavior of maxillary tumors also play a role in establishing the ameloblastoma of the maxilla as the most dangerous of the ameloblastomas.

Mastoid Bone

Parosteal osteogenic sarcoma (POS) is an uncommon surface bone tumor, most often arising from the metaphyseal end of long bones. Involvement of the cranial bones is rare, with only 1 case of mastoid bone POS previously reported in the literature. Two patients with POS of the mastoid are presented, 1 followed up for 25 years after surgical treatment. The presenting signs and symptoms, as well as distinctive radiographic findings, are discussed. Histologic features are also described. Typically, cranial POS appears as a sessile, densely ossified surface growth with radiating bone spicules that blend with surrounding soft tissue. Treatment is en bloc resection, which is curative in most cases.

Duodenal Invasion

Direct invasion of colorectal adenocarcinoma into adjacent structures occurs frequently, but only rarely is the duodenum involved. This study was undertaken to assess the safety and efficacy of en bloc resection of locally advanced right colon carcinoma invading the duodenum. A retrospective review of 49 patients with locally advanced colon cancer, surgically managed between 2000 and 2005, was performed. Forty-six patients underwent en bloc resection of colon and adjacent organs not involving the duodenum. Three patients with duodenal invasion underwent en bloc partial duodenectomy. The mean operative blood loss, length of stay, postoperative morbidity, and mortality compare favorably between these two groups of patients. Of the 46 patients with en bloc resection of other organs, 27 are alive at 12 to 60 months follow up. Two patients with duodenal invasion are alive without recurrence at 15 and 20 months follow up. En bloc resection of colon cancer invading the duodenum can be performed safely because morbidity and mortality rates are comparable to those attending extended resections of other locally advanced colon carcinomas. Overall survival in patients who underwent surgery with curative intent justifies en bloc duodenal resection in selected patients.

Abstract Myxoma is a benign tumor that arises from mesenchymal tissue and is found less commonly in the bone than in soft tissue. The majority of bony myxomas occur in the jaws. When compared with other odontogenic tumors, myxoma of the jaws is a rare entity. Numerous types of treatment have been used for these tumors including simple curettage, enucleation, curettage with peripheral ostectomy, and en bloc resection with or without immediate reconstruction. The buccal fat pad (BFP) is a lobulated mass of fatty tissue in the oromaxillofacial region, which has long been a source of grafts in facial augmentation. A case of an odontogenic myxoma in the left maxillary molar area of a 34-year-old female that was treated by curettage and peripheral ostectomy is presented. The surgical defect was successfully repaired with a pedicled BFP flap. Citation Öğütcen-Toller M, Şener I, Kasap V, Çakir-Özkan N.

Nowadays surgery is still the mainstay of solid tumors treatment. En Bloc resection is surgical treatment in amount of complete tumor removal. There remains considerable uncertainty about many aspects of resection boundaries, including definition and influence of anatomical and histological factors. One of the biggest challenges for the surgeon is choosing the right surgery for the «right» patient, taking into account the type of tumor and its biology.

An osteoblastoma in a carpal bone is very rare and presents a problem of reconstruction after wide tumour excision. We report a case of recurrent osteoblastoma of the right hamate bone with involvement of the ulnar carpal bones and soft tissues that was successfully treated by en bloc resection, temporary interposition of bone cement and fixation with K-wires, followed by reconstruction with a free vascularized iliac crest flap, tailored to the exact size of the defect, in a second procedure. Rapid fusion was achieved and hand function preserved with no evidence of recurrence 3 years postoperatively.

Uncommon Tumor

Periosteal lesions of the ulna diaphysis are rare, include a wide spectrum of tumors, and may cause considerable diagnostic problems. Surgical treatment may vary widely, based on an accurate diagnosis. We present the case of a periosteal, extraskeletal low grade myxoid chondrosarcoma of the ulna diaphysis. The surgical therapy included an en-bloc resection with allograft reconstruction. The patient showed a favorable outcome. Careful preoperative evaluation and planning are imperative to obtain a satisfactory oncological and functional outcome, especially with uncommon tumor presentations at rare locations.
