1/78. Ovarian cancer presenting as leukocytoclastic vasculitis.We describe a 53-year-old woman with a 4-month history of palpable purpuric papules on the upper and lower extremities. biopsy of the skin lesions revealed leukocytoclastic vasculitis. Although she denied any systemic symptoms, urinalysis demonstrated hematuria and proteinuria. Although the patient's skin lesions responded to prednisone, her urinalysis did not improve. A 10-cm complex mass involving the left ovary and adnexa was incidentally discovered on renal ultrasound. serum CA-125, an ovarian cancer marker, was elevated. laparotomy revealed ovarian carcinoma confined to the left ovary. After the cancer was resected, the patient's urinalysis slowly improved. Leukocytoclastic vasculitis (LCV) is infrequently associated with underlying malignancy and only rarely with solid tumors. We postulate that the patient's vasculitis represented a paraneoplastic phenomenon that allowed a diagnosis of asymptomatic ovarian carcinoma. To our knowledge, this is the first report of LCV occurring as the presenting sign of ovarian cancer.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
2/78. Bazex syndrome mimicking a primary autoimmune bullous disorder.Bazex syndrome is a paraneoplastic condition that is most frequently associated with squamous cell carcinoma of the upper aerodigestive tract. The lesions affect acral areas of the skin, including hands, feet, ears, nose, and, to a lesser extent, elbows and knees. Lesions mimic psoriasis and dermatitis. paronychia and nail dystrophy are frequent. Bullous lesions have been reported only rarely. We report a patient with Bazex syndrome with predominantly bullous lesions that mimicked a primary autoimmune bullous disorder.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
3/78. Constrictive bronchiolitis obliterans and paraneoplastic pemphigus.Constrictive bronchiolitis obliterans is rare, and the pathogenesis of the disease often remains unknown. This study reports on the case of a 38 yr-old female with constrictive bronchiolitis obliterans and paraneoplastic pemphigus associated with malignant lymphoma. The patient developed progressive obstructive lung disease. The chest radiograph showed almost normal lungs. Paraneoplastic pemphigus is a newly described syndrome in which patients have autoantibodies binding to some epithelia, including in the respiratory tract. The disease develops in association with non-Hodgkin's lymphomas or other malignant neoplasms. The case presented here suggests that constrictive bronchiolitis obliterans associated with paraneoplastic pemphigus may be one of the facets of autoimmune responses in this context.- - - - - - - - - - ranking = 0.97144078563197keywords = chest (Clic here for more details about this article) |
4/78. paraneoplastic syndromes of leukocytosis, thrombocytosis, and hypercalcemia associated with squamous cell carcinoma.paraneoplastic syndromes including leukocytosis, thrombocytosis and hypercalcemia are occasionally seen in patients suffering from progressive malignant disorders. Recent studies have revealed the production of several humoral factors by tumor cells and normal splenic cells of tumor-bearing patients to be the major cause of these reactions. granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte-colony stimulating factor (G-CSF), parathyroid hormone-related peptide, interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF) have been implicated. We describe a 58-year-old Japanese man with squamous cell carcinoma (SCC) on the left sole, which developed in a deep linear scar after a train crash. He developed pulmonary and lymph node metastases, then leukocytosis (57,110/mm3 with 95% neutrophilia), thrombocytosis (86.3 x 10(4)/mm3), and hypercalcemia (7.0 mEq/1), and finally cachexia, followed by death. serum G-CSF, IL-1 alpha, IL-1 beta, and TNF-beta were determined; revealing G-CSF and IL-1 beta levels were above the upper limits of their normal ranges at 39.2 pg/ml and 4.63 pg/ml, respectively. It is probable that these humoral factors were partially responsible for the paraneoplastic syndromes induced by the cutaneous SCC with metastasis in the present case.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
5/78. Diagnostic utility of magnetic resonance imaging skeletal survey in a patient with oncogenic osteomalacia.Oncogenic osteomalacia is a rare paraneoplastic syndrome characterized by hypophosphatemic osteomalacia due to renal phosphate wasting. The same biochemical features are found in patients with X-linked hypophosphatemic rickets/osteomalacia and sporadic hypophosphatemic osteomalacia with unknown etiology. Oncogenic osteomalacia is cured by resection of the responsible tumor. In contrast, patients with other types of hypophosphatemic rickets/osteomalacia need long-term treatment with large doses of active vitamin D3. Therefore, detection of the responsible tumor for oncogenic osteomalacia has great clinical importance. However, there is no standard method for detecting the tumor for oncogenic osteomalacia, and the responsible tumor is often very difficult to be found. We describe a patient with adult-onset osteomalacia due to renal phosphate wasting. Although oncogenic osteomalacia was suspected, cranial, chest, and abdominal computed tomography scanning, urological and otolaryngological examinations, and detailed palpation for soft tissue mass failed to detect the responsible tumor. However, magnetic resonance imaging skeletal survey revealed a tumor in the right femoral bone. Resection of the tumor resulted in normalization of serum phosphate and renal phosphate handling. Because the most frequent causes for oncogenic osteomalacia are tumors in bone or soft tissue, magnetic resonance imaging skeletal survey is a very powerful method for detecting the responsible tumor. Vigorous search for tumors with this method in patients with hypophosphatemic osteomalacia would be helpful not only for proper management of patients, but also for clarifying the identity of sporadic hypophosphatemic osteomalacia.- - - - - - - - - - ranking = 0.97144078563197keywords = chest (Clic here for more details about this article) |
6/78. Reversible paraneoplastic encephalomyelitis associated with a benign ovarian teratoma.BACKGROUND: Paraneoplastic encephalomyelitis (PEM) is a well characterized, and typically irreversible, paraneoplastic syndrome, usually associated with small cell lung cancer or other malignancy. We describe a case of a young woman with a benign ovarian teratoma who presented with a reversible PEM. CASE REPORT: A 24-year-old woman presented with a three week history of memory impairment, unusual behavior, personality changes, auditory hallucinations, hypersomnolence and binocular biplopia. On admission she was disoriented and inattentive with impaired short term memory. Small doses of lorazepam (1 mg), given for episodic agitation, repeatedly induced multidirectional bilateral nystagmus and a skew deviation, but her neurological examination was otherwise normal. A left-sided pelvic mass was palpable. brain MRI pre- and post-gadolinium was normal. There was a mild CSF pleocytosis and an EEG showed minimal bilateral background activity irregularities. There were no other laboratory abnormalities. Two weeks after admission, she clinically deteriorated developing central respiratory failure and a flaccid paraplegia. Repeat MRI showed an area of increased T2 weighted signal in the medulla and three similar areas in the spinal cord. Following removal of her tumor, treatment with high dose corticosteroids and intravenous immunoglobulin, she ultimately made a full recovery. pathology revealed the tumor to be a benign ovarian cystic teratoma. CONCLUSIONS: This is the first report of a reversible PEM seen in association with a benign tumor, in this case a mature ovarian teratoma. Presumably, an immune response directed against neural clements of the teratoma cross-reacted with normal brain, brainstem and spinal cord antigens to cause neurologic symptoms. Tumor removal was followed by neurologic recovery.- - - - - - - - - - ranking = 0.17906799897538keywords = back (Clic here for more details about this article) |
7/78. Immunofluorescent analysis of antibodies against neurons in the case of paraneoplastic syndrome.The authors report clinical and neuropathological findings especially immunofluorescent detection of antineuronal antibodies in the case of paraneoplastic syndrome in course of the small-cell lung carcinoma. The clinical symptoms, observed in 48-year-old woman, covered bilateral pyramidal syndrome, cerebellar syndrome, myasthenic syndrome and impairment of the cranial nerves. Neuropathological investigation revealed paraneoplastic encephalopathy in the form of encephalitis. Immunofluorescent analysis showed brightly fluorescent neurons standing out against a dull background.- - - - - - - - - - ranking = 0.17906799897538keywords = back (Clic here for more details about this article) |
8/78. Large annular purpura and paraneoplastic purpura in a patient with sjogren's syndrome and cervical cancer.We report a 79-year-old female with anaphylactoid purpura on her legs and unusual large annular purpura on the trunk. Histopathological characteristics of leukocytoclastic vasculitis were observed in the upper and middle dermis of both types of skin lesions. She was complicated by sjogren's syndrome and advanced cervical cancer. The annular purpura spontaneously resolved in a week and did not recur. However, the anaphylactoid purpura relapsed more frequently and spread more widely following the elevation of her serum SCC antigen levels from the onset of purpura until her death. We consider that the characteristic annular configuration was caused by the complication of sjogren's syndrome and that the recurrent anaphylactoid purpura indicated paraneoplastic vasculitis primarily caused by the tumor specific protein immune complexes. Complication by Sjogren's syndrome many also play a role in the development of allergic vasculitis.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
9/78. Primary angiitis of the central nervous system as a first presentation in Hodgkin's disease: a case report and review of the literature.OBJECTIVE AND IMPORTANCE: Granulomatous angiitis of the central nervous system is a rare cause of neurological deterioration. It is often diagnosed posthumously, and a high index of suspicion is necessary to make the correct diagnosis on a timely basis. CLINICAL PRESENTATION: A 27-year-old woman presented to the emergency room with complaints of worsening headache, nausea, and vomiting for 10 days, which were preceded by swelling of her tongue. At the examination, she had mild ocular tenderness, but no cranial nerve abnormalities. Radiographic examination revealed a right temporal lobe area with edema, and mild contrast enhancement was noted on computed tomography and magnetic resonance imaging. A similar but smaller region was present in the left frontal lobe. INTERVENTION: Stereotactic biopsy of the left temporal lobe revealed granulomatous angiitis. Further workup revealed Hodgkin's disease in the mediastinum. dexamethasone as well as chemotherapy for Hodgkin's disease was initiated. The patient's symptoms resolved, and she returned to work with her disease in remission. CONCLUSION: Previous reports of central nervous system angiitis have shown an association with sjogren's syndrome, herpes zoster infection, human immunodeficiency virus, and Hodgkin's disease. A review of the literature revealed a total of 12 patients with central nervous system angiitis and Hodgkin's disease. As a group, these patients had very poor outcomes. However, of six patients who presented with central nervous system angiitis and concurrent Hodgkin's disease and who underwent aggressive treatment for both conditions, three had a full recovery, two had a partial recovery, and one died.- - - - - - - - - - ranking = 0.46417247503067keywords = headache (Clic here for more details about this article) |
10/78. Acrokeratosis paraneoplastica (Bazex syndrome) with adenocarcinoma of the colon: report of a case and review of the literature.Acrokeratosis paraneoplastica is a rare disease and is uncommon even in patients with upper aerodigestive tract cancer. We report a 63-year-old man with a 1-month history of numerous pruritic lesions and vesicles on both feet. Although he had received local therapy, progressive dense scale formation involving both palms and both soles was found. colonoscopy was performed because of hematochezia, and it revealed an early colon cancer. After the resection of the cancer, the skin lesions began to fall off dramatically. To the best of our knowledge, there is no report of acrokeratosis paraneoplastica associated with colon cancer in the literature. This is the first case report of acrokeratosis paraneoplastica associated with early colon cancer.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
