This was a 60 year old woman, with a very large retro-pharyngeal tumour, mainly situated on the right, revealed by chronic decompensated respiratory failure. Admission to hospital was justified by deep coma with cyanosis of the face and extremities. She had taken 50 mg of Oxazepam the day before admission to hospital. This coma was due to chronic respiratory failure decompensated, as suggested by clinical and laboratory examination after elimination of any traumatic, neurological, endocrine or metabolic disorder. Intubation, rendered difficult by the retro-pharyngeal tumour and assisted ventilation permitted recovery of normal consciousness within 48 hours. This bi-lobed and encapsulated tumor was completely removed after full radiological assessment which showed the absence of any bony lesions. Histology suggested that this was a benign lipoma. The course was very rapidly favourable with a definite improvement in respiratory function one year after the surgical operation.

A clinically appearing, well-encapsulated lipoma was locally excised from the right posterior upper buccal gingival sulcus of a 24-year-old man and diagnosed histologically as pleomorphic liposarcoma. A right maxillectomy with preservation of orbital function was followed by 5,000 rads of planned postoperative radiation therapy. Four months later the tumor recurred outside of the original site, which has been controlled by further radiation and chemotherapy to these areas.

Fifty-seven thymomas, defined as neoplasms of the epithelial-reticular framework cells of the thymus, were assessed in respect to histologic type, inclusive of there ultrastructural aspects. The median age of the 57 patients was 40.4 years, with a range of 2 1/2--72 years. All neoplasms were located in the anterior mediastinum. The tumours in 40 cases were encapsulated and without invasion of adjacent tissue or implants (equal to non-invasive thymomas). The tumors in 17 cases were invasive of adjacent tissue, particularly mediastinal pleura, pericard and trachea. Six of 57 patients (equal to 10.5%) with thymomas have had a thoracic and supraclavicular lymph node metastasis, and osteolytic metastases in the vertebrae and sternum. Thirty-seven (equal to 64.9%) were so-called lympho-epithelial, 7 (equal to 12.3%) pure epithelial, 4 (equal to 7.0%) atypical (or anaplastic) with granulomatous focuses, 3 (equal to 5.3%) carcinoid and one (equal to 1.8%) seminomatous tumors. One patient have had a thymic cyst as a tumor-like conditions of the thymus, and four patients (equal to 7.0%) have had a thymo-lipoma. The histologic type of thymoma had no proof value in predicting prognosis with the exception of the so-called atypical or anaplastic thymoma. The fine structural aspects of thymomas and the fine structural differential diagnosis of anterior mediastinal tumors are discussed.

A patient with vague, nonspecific symptoms was initially thought to have an enlarged cardiac silhouette on chest roentgenogram, and a primary intracardiac disorder was suspected. At surgery, a mediastinal lipoma was diagnosed and excised. The roentgenographic appearance represents an unusual presentation of a mediastinal tumor.

Based on our first 200 investigations computed tomography of the heart is demonstrated as a new non-invasive roentgenography on typical examples and compared with the findings of the conventional roentgenogram. With the present technology the following indications for computed tomography of the heart seem to be reasonable: Calculation of size and volume of the cavities of the heart; intracavitary space occupying lesions (tumor, thrombus): demonstration of the thickness of the ventricular wall and ventricular septum and their changes caused by hypertrophy, myocardial infarction or septal defect; demonstration of aortic and ventricular aneurysm; demonstration of pericardial effusion, pericardial tumor, pericardial cyst of lipoma.

A case of interatrial septal lipoma, presenting as recurrent pericardial effusion with signs of constrictive pericarditis, was described. The tumor was removed successfully. The case demonstrated that the difficulties in the differential diagnosis between right atrial tumor and any other cardiac disease still exist. Because of its extreme rarity, the interatrial septal lipoma is rarely considered in the differential diagnosis.

Peripheral nerve tumors comprise less than 5% of all tumors of the hand. The most common solitary nerve tumor is the neurilemmoma, which arises from the neural sheath, is well encapsulated, minimally symptomatic, and may be surgically enucleated without producing a neurological deficit. Neurofibromas may be solitary, multiple, or associated with von Recklinghausen's disease. They are usually centrally placed with nerve fibers traversing the tumor mass making it more difficult to remove the tumor without producing permanent neurological damage. Malignant tumors include neurofibrosarcomas which often are very aggressive, requiring wide excision or amputation, and the rare neuroepitheliomas. Reported nerve tumors, intraneural in location but nonneural in origin, include fibrofatty infiltration of the median and digital nerves, intraneural lipoma, hemangioma, and ganglion cysts. These lesions may be treated by decompression or excision, depending on the nature of the tumor. Four unusual cases are described.

Liposarcomas of the oropharyngeal regions are exceedingly rare. Their silent, slow growth, submucosal or deep location, circumscription, and firm but resilient texture often suggest a diagnosis of a cyst or benign soft-tissue neoplasm. Two cases of well-differentiated myxoid liposarcoma are presented. The literature of over half a century was reviewed, and all documented cases were critically analyzed. The clinical data correlated with the histopathology and biologic behavior of the tumors indicated that two thirds of all liposarcomas of the head and neck are of the myxoid type. The well-differentiated myxoid liposarcoma was the most common one and has an over-all favorable prognosis. Lipomas of the oropharyngeal regions are relatively common and small, generally not exceeding 2.5 cm. in greatest diamter. A lobulated firm tumor of fast tissue significantly exceeding this size should be strongly suspected of being a liposarcoma.

Described by Lloyd and Dennis in 1963, Cowden's disease is a familial affection in which are found associated lesions of the buccopharyngeal mucosa (papillomatosis, papules, scrotal tongue), various types of skin lesions (verruciform keratotic papules, papilloma, lipoma, angioma, etc...), visceral manifestations usually related to lesions in the thyroid, breasts, or digestive tract (hamartoma or malignant tumors), and skeletal dysmorphism. The two patients were from different families, were aged 65 and 28 years, and had presented for consultation because of buccal mucous membrane papillomatosis, and in one case, hemorrhagic gingivitis. Cowden's disease was diagnosed from the clinical examination, past history, and investigations after hospital admission. The main value of the mucosal and cutaneous lesions is their diagnostic significance, enabling a synthesis of the multiple dispersed manifestations to be made, and a possible visceral tumor to be discovered in the early stages.

Thirty cases formerly diagnosed as Grade I lipogenic liposarcoma (well differentiated liposarcoma) were reviewed. The basic histologic pattern in all was that of adult fat modified by the presence of cells with enlarged, hyperchromatic nuclei; in most cases there was also a component of myxoid and/or fibrous tissue. The length of follow-up ranged from two to 30 years. Nine of the tumors were located in the subcutaneous layer. None of these recurred after excision, not even those which were simply "shelled out," and none metastasized. The term "atypical lipoma" is proposed for this group. Thirteen were located within or between muscles of the limbs, limb girdles, and head and neck. Nine of these recurred at least one, but there were no metastases and no deaths due to tumor. These were designated "atypical intramuscular lipoma." The remaining eight originated in the retroperitoneum. Although none of these patients developed metastases, five suffered inoperable recurrence and three died as a result of the neoplasm. It is suggested that the term "well differentiated retroperitoneal liposarcoma" be retained for cases of this type.
