Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature.

Pleural mesothelioma is usually divided into two forms of localized and diffuse type. Localized pleural fibrous mesothelioma is uncommon mesodermal neoplasm, which may occurs in both sexes and at the age of 50 years. This type of mesothelioma is usually asymptomatic and detected on routine chest X-ray and made fibrous tissue and shows of collagen fibers microscopically. Most localized fibrous mesothelioma arises from the visceral pleura and is well encapsulated and pedunculated mass. CT findings included well delineated, often lobulated, non-calcified soft tissue masses in close relation to a pleural space, associated pleural thickening, and absence of chest wall invasion and a peripheral or fissure location. Three cases of localized pleural fibrous mesothelioma diagnosed by resectional surgery were reported with the review of literature.

We experenced 18 patients with surgically treated thymoma from January 1986 to December 1993. There were 13 male and 5 female ranged from 23 to 69 years of age. Among them Myasthenia gravis was present in 8 patients (44%) The predominant cell type was lymphocytic(11 patients), followed by epithelial (3) and mixed (4), and had no value in predicting prognosis. Treatment consisted of complete resection in 15 patients, partial resection in 2 patients and 1 patient was performed biopsy. Only, and then adjuvant radiation therapy was done in 7 patients and 3 patients needed adjuvant chemotherapy. Invasion of the adjacent tissue in thymoma was the most improtant prognostic value. There were 6 non-invasive tumors and 12 invasive tumors. Two patients with invasive thymomas resulted in death and one of 6 patients with non-invasive thymomas died during follow up ranged from 25 day to 60 months. The causes of death were myasthenic crisis in 1 patient, C. N. S. problem in 1 patient and pulmonary & mediastinal metastasis in 1 patient.

Angiosarcoma of the brain, either primary or metastatic is extremely rare. Moreover, angiosarcoma metastazing to the brain is also highly unlike to occur when comparing with metastases to the other organs. Thus, an ideal treatment strategy has not been established. A 67-year-old man with past surgical history of a scalp angiosarcoma underwent surgical resection of intracranial invasion. Because of wide scalp flap excision and resultant poor vascularity of the scalp flap, additional radiation was not provided. Because adjuvant therapy is impossible due to poor scalp condition, more careful but ample resection of the primary lesion is essential to conduct initial operation.

Advanced esophageal carcinoma which invades into adjacent organs are classified as T4 esophageal cancer,. Its complete resection without residual tumor would be difficult. Preoperative chemoradiotherapy and combined modality therapy are being tried to improve survival in patients with T4 esophageal carcinoma. In a 74-year-old man a 6cm squamous cell carcinoma of the esophagus with invasion of the thoracic aorta was detected (T4). After neoadjuvant chemoradiotherapy the patient was operated on using bio-pump with aorto-femoral cannulation. The invased segment of descending aorta was resected and reconstructed with a graft. The tumor was resected and EG anastomosis was done. The postoperative period was uneventful the patient was discharged after good condition and has been well to now.

Adrenal cortical tumors are rare in adults and children. Most are malignant and functional. The principal clinical features are virilization, Cushing's syndrome, hyperaldosteronism and feminization. Recently, we treated a case of virilizing adrenal cortical tumor in a 26 month-old boy. The diagnosis was made by hormone assay, abdominal CT and tissue pathology. Right adrenalectomy was successful performed. Pathologic examination revealed an adrenal cortical adenoma with vascular invasion.

Adenoid cystic carcinoma is malignant neoplasm belonging to a group of tumors of salivary gland origin. It is an aggressive tumor characterized by slow growth and incidious destruction of surrounding tissues. Perineural invasion is a prominent feature. Spread to regional lymph node is rare, other than by direct extension. Distant metastasis are more common. We experienced a 65-year old female with adenoid cystic carcinoma of minor salivary gland in retromolar pad.

Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated. Afterward, surgical enucleation was performed. The size of the lesion continued to shrink after marsupialization, and the maxillary sinus restored its volume. This patient has been followed-up for 3 years after the surgery, and there have not been any signs of recurrence.

Mammary cancer is the most common malignant neoplasm in the bitch. It constitute 40 percent of all tumors in female dogs, which is three times higher than incidence of mammary tumors in humans[2]. Cytological differentiation between benign and malignant canine mammary tumors is difficult, however, an irregular chromatin pattern was reported to be a significant criterion for malignancy[1]. It can be estimated that approximately 30 percent of the surgically removed mammary tumors are malignant[4]. Malignant mammary tumors often have some degree of infiltrative/destructive growth into adjacent tissues and/or invasion of vessels. Malignant mammary tumors often metastasize into local lymph nodes and lungs, and less frequently into other organs[3]. Based on histological and cytological criteria, this case was diagnosed as tubulopapillary carcinoma of the mammary gland. (omitted)
