1/10. Late lethal secondary hemorrhage after laser supraglottic laryngectomy.Since 1971, a number of articles have been published regarding the complications encountered with laser surgery of the larynx. Most investigations focus on complications such as accidental burns caused by the reflection of the laser beam, endotracheal explosion, special anesthesiologic problems, edema of the mucosa leading to airway obstruction, and abnormal scar formation with functional problems. Secondary hemorrhage has played a subordinate role, and in the few articles that have focused on it, cases requiring postoperative treatment have been reported only sporadically. All of these cases occurred within the first postoperative week, and no case resulting in the death of a patient was reported. We describe a patient in whom a lethal secondary hemorrhage occurred 10 days after a laser supraglottic laryngectomy. Because of the increase of laser applications in the treatment of laryngeal carcinoma, similar complications may be encountered. We comment on possible pathophysiological mechanisms and consequences.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
2/10. radiation-induced malignant fibrous histiocytoma of the neck in a patient with laryngeal carcinoma.Fibrohistiocytomas are soft tissue tumors of histiocytic origin that have a variety of histological patterns. Although cases of malignant fibrous histiocytoma (MFH) of the head and neck have been reported with increasing frequency in recent years, they are considered rare. We report a case of the giant cell variant of MFH of the neck in which the patient had been given radiotherapy for T1 glottic cancer. prognosis of MFH, the use of radiation as primary treatment, and its role in the development of secondary primary tumors in the head and neck region are reviewed. [editorial comment: The authors stress the important relationship between prior radiation therapy and the induction of new tumors.]- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
3/10. Gingival squamous cell carcinoma: a clinical case and differential diagnosis.A 59-year-old woman presented with a tumor of the gums located in the second quadrant for the past 6 weeks. The histopathological findings are presented and the most likely differential diagnoses are commented (pyogenic granuloma, squamous cell carcinoma and gingival metastases), along with the importance of the radiological features. The definitive diagnosis requires concordance among the clinical, radiological and histopathological characteristics of the lesion.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
4/10. Gram negative aerobic bacillus pneumonia in oral and maxillofacial surgery--a case for comment.A case illustrating the potentially fatal complication of endogenous Gram Negative Aerobic bacillus (GNAB) septicaemia secondary to nosocomial pneumonia is presented along with current theories as to its aetiology. The technique of selective decontamination of the digestive tract is designed and advocated to prevent such occurrences; oral and maxillofacial surgeons should be aware of this approach. It may be, however, that by using much simpler manoeuvres such as changes in policy regarding gastric stress ulcer prophylaxis, the already small risk of such an occurrence will be further reduced. awareness of this condition will allow a higher index of suspicion when presented with catastrophic septic complications on the ITU and aid in more rational planning of antimicrobial therapy.- - - - - - - - - - ranking = 4keywords = comment (Clic here for more details about this article) |
5/10. Oral squamous acanthoma. Two additional cases with comments on etiology.Two new cases of squamous acanthoma are presented, and the their clinical characteristics are compared to the eight cases previously reported. These two additional examples of this lesion are clinically similar to those previously reported. However, one of the two cases exhibits resolution after the removal of sources of trauma, thus lending support to the previously proposed theory of traumatic etiology.- - - - - - - - - - ranking = 4keywords = comment (Clic here for more details about this article) |
6/10. Squamous cell carcinoma of the stomach: a study of four patients with comments on histogenesis.The histogenic origin of squamous carcinoma of the stomach (SCS) is controversial. We report the case of a 55-year-old man who developed SCS following successful chemotherapy for generalized well-differentiated lymphocytic lymphoma. The patient's stomach contained both squamous carcinoma arising in squamous metaplasia and chronic atrophic gastritis with intestinal metaplasia. This case is compared to three additional cases of SCS where no such antecedent mucosal changes were evident. The SCS literature is reviewed and the histogenesis regarding the development of pure squamous tumors of the stomach is discussed.- - - - - - - - - - ranking = 4keywords = comment (Clic here for more details about this article) |
7/10. Unusual appearances of cancers in the skin.Markedly unusual appearances of cutaneous cancers are uncommon, but they deserve comment upon for reasons other than their appearances. Ten unusual cases are illustrated and briefly commented upon.- - - - - - - - - - ranking = 2keywords = comment (Clic here for more details about this article) |
8/10. KTP laser excision of a soft palate squamous cell carcinoma: a case report.Squamous cell carcinoma of the soft palate is an infrequently seen tumor of the oral cavity. The use of the KTP laser in the treatment of a 52-year-old man with a T2N0M0 soft palate carcinoma is reported. The natural history and treatment of this entity is reviewed. The application of tumor thickness as related to therapy of the neck and prognosis is commented on. Use of the KTP laser for resection of oral cavity lesions is felt to be a technological improvement beneficial to both patients and practitioners.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
9/10. carcinoma ex pleomorphic adenoma of the palate--a case report.A case of squamous cell carcinoma ex pleomorphic adenoma in a palate is presented and comments on diagnostic criterias are described. The patient was 36-year-old male presenting with an ovoid elevated palate mass for 6 months. The tumor located in the junctional area of soft and hard palate. The mucosa was diffusely ulcerated and the mass focally tightly adherent to adjacent tissue. The initial cytologic and pathological diagnosis by fine needle aspiration biopsy and open biopsy was benign pleomorphic adenoma. After total removal, histologic examination revealed that tumor was composed partly of benign pleomorphic adenoma and partly of an squamous cell carcinoma component with areas of necrosis and capsular invasion. Immunohistochemical staining in the carcinoma area revealed positive reaction for low and high molecular weight cytokeratin, and epithelial membrane antigen, but negative for desmin, actin, GFAP and S-100 protein. in situ hybridization using biotinylated Epstein-Barr virus probe was done and the neoplastic cells were negative. Our case in an unusual partially encapsulated carcinoma ex pleomorphic adenoma in the palate and is not related in EBV infection.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
10/10. Hemicorporectomy: a case study from a physical therapy perspective.Hemicorporectomy, literally translated, means half (hemi), body (corpus), removal (ectomy). The procedure is indicated as a last resort measure for patients with life-threatening conditions such as advanced pelvic tumors, pelvic osteomyelitis, crushing pelvic trauma, or intractable decubiti in the pelvic region. We report a case in which this mutilating procedure was performed on a 49-year-old man with extensive perineal and sacral sores. Squamous cell carcinoma was detected and isolated to the pelvic region. His medical history was significant for paraplegia secondary to a gunshot wound in 1966. The literature has documented fewer than 45 procedures of this radical nature. Few of the case studies specifically address the rehabilitation of this patient population and none of the articles researched were written from a physical therapy standpoint. Articles that addressed the concept of rehabilitation comment only that the course of rehabilitation was extensive and prolonged. This report provides an overview of the surgical procedures and specifically addresses the physical rehabilitation of this patient after his hemicorporectomy from a physical therapy perspective. This patient's physical therapy was accomplished over a time span of less than 1 month.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
