1/224. Phantom erection after amputation of penis. Case description and review of the relevant literature on phantoms.BACKGROUND: perception of a phantom limb is frequent after an amputation of an upper or lower extremity. Phantom penis is reported infrequently. METHOD: Case description and literature review. RESULT: The phenomenon of phantom penis followed total penectomy. Several aspects were unusual, particularly the existence with phantom only in the erect state, and associated recrudescence of a preoperative painful ulcer. General features of limb phantoms after amputation are reviewed including a resume of recent studies of cortical reorganization. The phantom process is analyzed looking for clues to the nature of the underlying neural organization. The puzzle of phantom pain is briefly touched on. CONCLUSION: The development of the phantom is attributed to activity in the deafferented parietal sensory cortex.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
2/224. Refractory arthropathy after intravesical bacillus Calmette-Guerin therapy. Usefulness of isoniazide.BACKGROUND: arthritis associated with bacillus Calmette-Guerin immunotherapy usually responds dramatically to nonsteroidal antiinflammatory drug therapy. isoniazid is generally reserved for other complications such as granulomatous hepatitis. CASE-REPORT: A 73-year-old man was admitted for fever, arthritis of the knees and right temporomandibular joint, an inflammatory swelling over the left achilles tendon and bilateral conjunctivitis. The symptoms started in the wake of a course of intravesical bacillus Calmette-Guerin immunotherapy. Laboratory tests showed evidence of severe inflammation. Cultures of blood, urine and joint fluid specimens were negative, as were tests for autoantibodies and serologic tests for organisms known to cause reactive arthritis. Nonsteroidal antiinflammatory therapy was ineffective and glucocorticoid therapy produced only a partial response. All the symptoms resolved under isoniazid therapy in a dosage of 300 mg/day for three months. CONCLUSION: Use of antituberculous agents may be required in some cases of arthritis associated with bacillus Calmette-Guerin immunotherapy, most notably those with severe pyrexia.- - - - - - - - - - ranking = 0.5keywords = organ (Clic here for more details about this article) |
3/224. Progression of a Nelson's adenoma to pituitary carcinoma; a case report and review of the literature.A 25-year-old woman developed Nelson's syndrome, 3 years after successful bilateral adrenalectomy for Cushing's disease. Despite pituitary surgery and radiotherapy the tumour showed invasive growth, leading to visual disturbance, paresis of the oculomotor nerve and, 34 years after adrenalectomy, to death by widespread purulent leptomeningitis. autopsy revealed a large adenohypophyseal carcinoma with a metastasis attached to the dura, both tumours showing immunocytochemical staining for ACTH and TSH. We review the literature on metastatic adenohypophyseal carcinoma in Cushing's disease and Nelson's syndrome and discuss the role of proliferation markers as indicators of malignant progression.- - - - - - - - - - ranking = 1.5674787402752keywords = nerve (Clic here for more details about this article) |
4/224. Intraosseous epithelioid malignant peripheral nerve sheath tumor of the phalanx. Case report.We report the first case of intraosseous epithelioid malignant peripheral nerve sheath tumor (MPNST) occurring in the phalanx. The patient was a 50-year-old Japanese man with an intramedullary lytic lesion of the proximal phalanx. Microscopically, the tumor was composed of epithelioid cells or polygonal cells, forming large cell nests with central necrosis. Most tumor cells were diffusely and strongly immunopositive for S-100 protein and vimentin, and negative for cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, alpha-smooth muscle actin, and HMB-45. laminin-positive material was discontinuously demonstrated between the individual tumor cells. Electron microscopy showed prominent external lamina. Our case indicated that laminin is useful for differentiating epithelioid MPNST from metastatic carcinoma and malignant melanoma.- - - - - - - - - - ranking = 7.837393701376keywords = nerve (Clic here for more details about this article) |
5/224. A case of synchronous double primary lung cancer with neuroendocrine features.We report a case of unique double primary lung cancers with neuroendocrine features in a 63-year-old male smoker. The mass in the left lower lobe (LLL) was a small cell/large cell carcinoma with spindle cell sarcomatous areas and organoid structure. The mass in the left upper lobe (LUL) was a tubular adenocarcinoma with neuroendocrine features including organoid nests showing occasional rosette formation, nuclear palisading in the periphery of the nests and positive immunoreaction for CD56, chromogranin a and synaptophysin. The difference in histological structures between the two masses led us to diagnose double primary lung cancer. The combination of small cell lung carcinoma and spindle cell carcinoma is very uncommon. The relationship between LLL and LUL tumors remains unclear. Multiple lung cancers with neuroendocrine features have only rarely been reported in the literature. The patient in our case died of widespread cancer 2 years and 4 months after the surgery without adjuvant chemotherapy, a longer postoperative survival time than in cases of ordinary extensive small cell lung cancer. Multiple lung cancers with neuroendocrine features are extremely rare and similar cases have not been reported in the literature. Neuroendocrine differentiation has attracted widespread attention and, therefore, examining neuroendocrine features in lung cancers is important.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
6/224. Hybrid carcinomas of salivary glands. Report of 4 cases and review of the literature.OBJECTIVE: To report 4 cases of hybrid carcinoma and to review the literature on these rare neoplasms of the salivary gland. methods: hematoxylin-eosin-stained, formalin-fixed, paraffin-embedded tissue sections from 3 parotid tumors and 1 palate tumor were examined. RESULTS: The cases were classified as adenoid cystic and mucoepidermoid carcinoma, adenoid cystic and epithelial-myoepithelial carcinoma, epithelial-myoepithelial and salivary duct carcinoma, and adenoid cystic and salivary duct carcinoma. All patients were men, 28 to 71 years old; 3 patients presented with parotid mass, and 1 patient presented with palatal mass. One patient presented with facial nerve paralysis and pain. The soft palatal tumor was a slowly growing mass with maxillary sinus involvement at the time of the diagnosis. All patients were treated with surgery and radiotherapy. CONCLUSIONS: Correct identification of 2 or more neoplastic entities will help assess the aggressiveness and metastatic potential of the tumor and influence the clinical course and treatment.- - - - - - - - - - ranking = 1.5674787402752keywords = nerve (Clic here for more details about this article) |
7/224. dna mismatch repair deficiency in curatively resected sextuple primary cancers in different organs: a molecular case report.A male patient synchronously or metachronously underwent six curative resections after diagnoses of cancers in the rectum, urinary bladder, stomach, colon, liver and lung. Five cancers, excluding early colon cancer, were analyzed for instability in seven microsatellite markers and in transforming growth factor beta type II receptor, insulin-like growth factor ii receptor and BAX. All analyzed cancers had replication errors and instability in at least one target gene. These results suggest that abnormal dna mismatch repair system plays a major role in the occurrence of multiple primary cancers in this case.- - - - - - - - - - ranking = 2keywords = organ (Clic here for more details about this article) |
8/224. Leptomeningeal carcinomatosis and cranial nerve palsy as presenting symptoms of a clinically inapparent gallbladder carcinoma.We present an occult metastatic signet-ring cell gallbladder carcinoma in a 78-year-old woman, who complained of recurrent headaches, dysarthria, and paresis of the tongue. Cranial imaging showed contrast enhancement of the basal leptomeninges, and the cerebrospinal fluid displayed clusters of adenocarcinoma cells proposed as leptomeningeal carcinomatosis of the breast, lung or gut. However, postmortem examination revealed the gallbladder as the site of the primary carcinoma with focal signet-ring cell differentiation. In patients with progressive neurologic deterioration due to leptomeningeal carcinomatosis, adenocarcinomas from the gastrointestinal and hepatic systems should be considered. It is likely that signet-ring cell carcinomas display an increased affinity to leptomeningeal spread.- - - - - - - - - - ranking = 6.2699149611008keywords = nerve (Clic here for more details about this article) |
9/224. Multifocal polyradiculoneuropathy and carcinoma of the thymus.We studied a patient with polyradiculoneuropathy with anaplastic carcinoma of the thymus. Motor manifestations dominated. Postmortem examinations indicated that the primary changes were in the spinal nerve roots, peripheral nerves and, possibly, the spinal anterior horn cells. The posterior funiculi and posterior root ganglia were also affected, implying multifocal and multiphasic degeneration. This unusual polyradiculoneuropathy is a form of carcinomatous neuropathy.- - - - - - - - - - ranking = 3.1349574805504keywords = nerve (Clic here for more details about this article) |
10/224. endophthalmitis from mycobacterium bovis-bacille Calmette-Guerin after intravesicular bacille Calmette-Guerin injections for bladder carcinoma.PURPOSE: To present clinical and histologic findings of intraocular infection with mycobacterium bovis-bacille Calmette-Guerin after intravesicular bacille Calmette-Guerin injections for treatment of bladder carcinoma. methods: A 77-year-old man was initially seen with visual acuity of 20/200, focal retinitis, vasculitis, and progressive vitreous opacity in the right eye and visual acuity of light perception, intraocular inflammation, and a dense cataract in the left eye 14 months after intravesicular injection of live bacille Calmette-Guerin organisms. RESULTS: Vitreous cultures in the right eye demonstrated growth of bacille Calmette-Guerin organisms. Bilateral loss of light perception occurred despite systemic antimy-cobacterial therapy. Histopathologic examination demonstrated nongranulomatous inflammation and acid-fast bacilli in both eyes. CONCLUSION: Delayed endogenous endophthalmitis may develop after intravesicular bacille Calmette-Guerin injection that may not respond to systemic agents. Intravitreal therapy may be indicated.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
