Calcified amorphous tumor of the heart with mitral annular calcification: a case report

Abstract Background Calcified amorphous tumor of the heart is a rare, non-neoplastic cardiac mass characterized by nodular calcium in the background of amorphous degenerating fibrinous material. Clinical diagnosis of calcified amorphous tumor can be difficult, and current single imaging techniques do not specifically differentiate calcified amorphous tumor from other cardiac tumors such as calcified atrial myxoma, calcified thrombi, or vegetation. Complete surgical resection is the treatment of choice for both symptom improvement and prevention of embolization, as well as for pathological diagnosis. Case presentation A 70-year-old Asian man with end-stage renal disease complained of chest discomfort during exercise. He had no history of thromboembolism or endocarditis. A transthoracic echocardiogram revealed mitral annular calcification as well as a highly mobile mass (8 × 6 mm) attached to the ventricular side of the posterior mitral valve leaflet. As the mass was highly mobile, suggesting a high risk of embolization, he underwent surgical resection. A histopathological examination revealed multiple nodular amorphous calcifications, along with fibrous connective tissue. There were no identifiable myxoma or malignancy cells. Consequently, the diagnosis of calcified amorphous tumor was confirmed. Conclusions In the present case, a calcified amorphous tumor arose from mitral annular calcification. A characteristic of mitral annular calcification-related calcified amorphous tumor is its highly mobile nature, with a high risk of stroke or other systemic embolism. Therefore, surgical therapy should be considered for treatment of calcified amorphous tumors

The efficacy of superselective intra-arterial infusion with concomitant radiotherapy for adenoid cystic carcinoma of the head and neck

Conclusions: Superselective intra-arterial cisplatin infusion with concomitant radiotherapy (RADPLAT) is considered to be one of the treatments of choice for patients with adenoid cystic carcinoma (ACC) who prefer not to undergo radical surgery. Objective: To evaluate the efficacy of RADPLAT for patients with ACC of the head and neck. Patients and methods: Between 2001-2010, nine patients with untreated ACC were given superselective intra-arterial infusion of cisplatin (100-120 mg/m(2)/ week) with simultaneous intravenous infusion of thiosulfate to neutralize cisplatin toxicity and radiotherapy (65-70 Gy). Results: Five patients had tumors arising in the base of the tongue, two in the maxillary sinus, and the remaining two in the nasopharynx. The median follow-up period was 9 years 7 months (9; 7) (range = 4; 6-12; 5), and the 5-year local control (LC), overall survival (OS), and disease-free survival rates were 88.9%, 88.9%, and 55.6%, respectively. The 10-year OS rate was 57.1%, but all patients who remained alive for over 10 years are still alive with disease. Primary tumor recurrence was observed in five of the nine patients, with the median time to recurrence being 6 years (range = 4-9 years). Five of the nine patients had distant metastasis, and of these three patients also had primary recurrence

The role of endoscopic resection for selected patients with sinonasal squamous cell carcinoma

Objective: Despite of rapid advances in endoscopic surgery, the gold standard for sinonasal squamous cell carcinoma (SNSCC) surgery has remained the open approach with en-block resection due to the aggressive nature of SNSCC, including frequent recurrence and high mortality rate. For that reason, few studies have focused on SNSCC treated by endoscopic surgery alone. The objective of this study was to evaluate the usefulness of endoscopic surgery for patients with SNSCC. Methods: A retrospective analysis was performed for 15 consecutive SNSCC patients who underwent endoscopic surgery without an open approach. We carefully selected patients whose tumor attachment sites could be fully visualized and completely resected through an endonasal approach. Results: Of the fifteen patients, 4 patients (27%) were diagnosed with T1, 7 (47%) with T2, 4 (27%) with T3, and no patients with T4a or T4b disease. Four of the 15 (27%) patients showed positive surgical margins. The 5-yr overall survival, disease-specific survival, and local control rate was 72.4%, 79.6%, and 92.9%, respectively. The 5-yr disease-specific survival for T1, T2, and T3 disease was 100% and 75% and 75%, respectively. Patients with negative surgical margins had a better disease-specific survival rate than did those with positive surgical margins (p = 0.0253). Conclusion: Endoscopic surgery for patients with SNSCC appears to afford an effective method in selected cases. The achievement of negative surgical margins with a good view of the tumor attachment site was considered to be critical to the management of SNSCC.

Management for squamous cell carcinoma of the nasal cavity and ethmoid sinus : A single institution experience

Objective: Here we report our experience of patients with squamous cell carcinoma (SCC) of the nasal cavity and ethmoid sinus (NC&ES) together with an analysis of treatment outcomes. Methods: A retrospective analysis was performed using data from 25 consecutive patients treated between 2000 and 2012. Four patients were diagnosed with T1, 3 with T2, 4 with T3, 7 with T4a, and 7 with T4b disease. No patient had lymph node metastasis. Results: Twelve patients were treated with surgery with/without radiotherapy and with/without chemotherapy. Of these, 4 underwent endoscopic surgery without an open approach and 3 required an anterior skull base approach. Thirteen were treated with radiotherapy; 1 with radiotherapy alone, and 4 and 8 with intravenous and intra-arterial chemotherapy, respectively. The 5-yr overall survival for T1-3, T4a, and T4b disease was 53.9%, 71.4%, and 29.0%, respectively. The 5-yr disease-specific survival for T1-3, T4a, and T4b disease was 74.1%, 71.4%, and 29.0%, respectively. Conclusion: Our treatment policy for patients with SCC of NC&ES, which basically follows the NCCN guideline, was considered to be appropriate. However, several points in terms of surgery and nonsurgical approach remain to be solved through further research
