1/3. Aggressive psammomatoid ossifying fibroma of the inferior turbinate and lateral nasal wall.OBJECTIVE: Fibroosseous lesions are rare entities of the nose and paranasal sinuses, the terminology and classification of which are still confusing. Psammomatoid or aggressive (juvenile) ossifying fibroma is a benign messenchymal tumor usually met in the young age (5-15 years), in the sinonasal tract, bearing distinctive histomorphologic features and a tendency towards locally aggressive behaviour. METHODOLOGY: We report here a rare case of an aggressive psammomatoid ossifying fibroma of the inferior turbinate and the lateral nasal wall, with obstruction of the nasolacrimal duct, in a 68-year-old woman. RESULTS: diagnosis was based on physical examination, CT scan imaging and histopathological examination. Treatment consisted of endoscopic intranasal resection of the tumor accompanied by removal of the lateral nasal wall. CONCLUSIONS: Fibro-osseous tumors of the nose and paranasal sinuses require aggressive surgical approach in order to avoid recurrence. Complete surgical excision may not always be possible mainly due to the tumor's extent and location.- - - - - - - - - - ranking = 1keywords = physical examination (Clic here for more details about this article) |
2/3. Successful low-dose chemotherapy using vinblastine and methotrexate for the treatment of an ileoanal pouch mesenteric desmoid tumor: report of a case.The purpose of this report was to describe the first known case of ileoanal pouch salvage by a low-dose regimen of vinblastine and methotrexate chemotherapy for the treatment of desmoid tumor arising from the mesentery of the ileoanal pouch in a patient who had undergone ileal pouch-anal anastomosis for familial adenomatous polyposis. Mesenteric desmoid tumor involving the ileoanal pouch in a 28-year-old female was treated with vinblastine and methotrexate biweekly for 12 months and monthly for 12 months in an outpatient unit. The desmoid tumor response to the treatment was assessed at routine intervals by physical examination and magnetic resonance imaging. Desmoid tumor was successfully treated with a low-dose regimen of vinblastine and methotrexate chemotherapy without significant side effects, and function of the ileoanal pouch was fully preserved. magnetic resonance imaging showed a decrease in desmoid tumor size and cellularity, and changes consistent with fibrosis. This is a unique case highlighting the possibility of ileoanal pouch salvage by low-dose combination chemotherapy using vinblastine and methotrexate in a familial adenomatous polyposis patient with mesenteric desmoid tumor.- - - - - - - - - - ranking = 1keywords = physical examination (Clic here for more details about this article) |
3/3. Desmoid tumor: a case of mistaken identity.Desmoid tumors are rare tumors accounting for only 0.03% of all neoplasms. Mainly occurring in the fourth and fifth decades of life, these tumors originate in musculoaponeurotic tissues of the limbs, neck, trunk, abdominal wall, and mesentery. We present a rare case of a chest wall desmoid tumor that was mistaken for breast cancer on both physical examination and mammography, which highlights the unique risk these tumors present for confusion with other malignant processes. Although past literature contains numerous reports of other misdiagnoses, this case is unique in reporting the potential for misdiagnosis between chest wall desmoid tumors and breast cancer. In cases where suspicious breast findings do not correlate to usual diagnostic measures, such as fine-needle aspiration or core needle biopsy, the possibility of another pathology such as a chest wall desmoid tumor mimicking breast cancer should be considered in the differential diagnosis.- - - - - - - - - - ranking = 1keywords = physical examination (Clic here for more details about this article) |
