1/142. Double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes: report of a case.A case of double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes is reported. A 73-year-old man with hemosputum was found to have a mass in his right lower lung field on a chest X-ray. Based on a diagnosis of lung cancer, a right middle and lower lobectomy with a dissection of the lymph nodes was performed. Microscopically, a well developed granulomatous reaction was seen in the dissected mediastinal and hilar lymph nodes. Three years after the pulmonary resection, he was admitted to our hospital because of dysphagia. A diagnosis of lower esophageal cancer was made. A lower esophagectomy with a total gastrectomy was performed. A sarcoid-like reaction comprising epithelioid cells and giant cells was seen in the regional lymph nodes. No clinical findings indicative of systemic sarcoidosis were observed. This rare condition may therefore help to improve our overall understanding of the relationship between malignant neoplasms and sarcoid-like reactions in the regional lymph nodes.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/142. Peritoneal sarcoidosis: case report and review of the literature.OBJECTIVES: This study was performed to report a patient with peritoneal sarcoidosis and review the literature for similar cases. methods: We described the clinical presentation, course, and outcome of the patient, and reviewed the medical literature from 1966 till 1997 using medline and the key words sarcoidosis, scar, and peritoneum. RESULTS: Our patient presented with a rapidly growing tumor-like mass at the site of an old appendectomy scar. laparoscopy showed a large peritoneal mass and multiple small peritoneal nodules that were found to be noncaseating granulomas by pathology. The medline search uncovered only 16 cases of peritoneal sarcoidosis, most of which presented with ascites. CONCLUSION: This case illustrates the need to consider sarcoidosis, in addition to infections and neoplasms, in the differential diagnosis of peritoneal nodules and exudative ascites.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/142. lymphomatoid granulomatosis in a child with acute lymphatic leukemia in remission.lymphomatoid granulomatosis, a tumor-like process of unknown etiology, produced progressively destructive disease of the larynx, trachea and bronchi in an eight-year-old girl with acute lymphoblastic leukemia of five years duration. The leukemia had been in remission for 4 1/2 years at the clinical onset of the lymphomatoid granulomatosis. Whether this occurrence suggests that lymphomatoid granulomatosis is a type of neoplasm, or is associated with immunologic depression, cannot be stated. Fortunately rare, and of poor prognosis, the disorder may become more frequent with improved survival rate of patients with leukemia and other neoplasms.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
4/142. myiasis secondary to Sermatobia hominis (human botfly) presenting as a long-standing breast mass.A case of a 54-year-old woman who presented with a breast mass is reported. Histologically, a chronic granulomatous inflammatory response was observed. The response was associated with an organism diagnosed as a fly larva, Dermatobia hominis (human botfly). The incidence of myiasis, infestation by fly larvae, presenting as a long-standing breast mass and mimicking a neoplasm is extremely rare, especially in the united states.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/142. Fibro-osseous lesions of the central nervous system: report of four cases and literature review.Fibro-osseous lesions, also reported as calcifying pseudoneoplasms of the neural axis, are uncommon lesions of the CNS. We report four additional cases: two extraaxial and two intraaxial, in patients ages 33, 47, 49, and 59 years at presentation. Fibro-osseous lesions involving the CNS demonstrate variable proportions of fibrous stroma, bone, palisading spindle to epithelioid to multinucleated cells in association with a highly distinctive, perhaps pathognomonic, chondromyxoid-like matrix often distributed in a nodular pattern. This histopathologically distinctive lesion can be seen in many regions of the neuraxis, often with a dural association, and most commonly along the vertebral column. It appears to be a slow-growing lesion and, with wide excision, the prognosis is excellent. The etiology remains unclear, but the preponderance of data favors a reactive rather than neoplastic process. If this putative pseudotumor is not recognized histopathologically, a neoplastic or infectious differential might result in inappropriate investigations and potentially harmful therapies.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
6/142. Xanthogranulomatous tubo-ovarian abscess resulting from chronic diverticulitis.We report a case of xanthogranulomatous tubo-ovarian abscess which was preoperatively suspected to be an adnexal neoplasm. With foreign body material found in the abscess wall and vegetable fiber in the tubal lumen, a previously treated chronic diverticulitis was the presumed cause. culture studies showed polymicrobial isolates which included escherichia coli, an enteric pathogen. After surgery, administration of antibiotics, and revision of delayed subcutaneous wound healing, the patient is reportedly well.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/142. erdheim-chester disease with intramuscular lipogranuloma.We report on a rare manifestation of erdheim-chester disease with intramuscular lipogranuloma. The patient was a 66-year-old man who noted a soft tissue mass in the right quadriceps femoris muscle. Radiographs revealed symmetrical osteosclerosis in the diametaphysis of both femora and tibiae. An open biopsy revealed a proliferation of lipid-laden histiocytes in the femoral bone marrow and the quadriceps femoris muscle. To our knowledge, this is the second case of erdheim-chester disease involving muscle.- - - - - - - - - - ranking = 0.10589207682793keywords = soft (Clic here for more details about this article) |

Bilateral xanthogranulomatous perinephritis without renal parenchymal involvement.A case of isolated bilateral xanthogranulomatous perinephritis, which presented as a symmetrical irregular perirenal rim of soft tissue, is reported.

9/142. Disseminated and recurrent sarcoid-like granulomatous panniculitis due to bovine collagen injection.Three to five percent of patients treated with injectable collagen implants have adverse local reactions. Systemic signs or symptoms are infrequent. We describe the case of a 53-year-old woman who developed local and general complaints 2 months after receiving two collagen injections in both nasolabial folds. She presented asthenia, malaise, polyarthralgia and inflammatory nodular panniculitis in the places of injection as well as on the forearms and lower extremities. skin testing was compatible with hypersensitivity to collagen. This case raises the question as to whether the injection of animal-derived collagen induces manifestations similar to those observed in connective autoimmune diseases or human adjuvant disease.- - - - - - - - - - ranking = 1.1460374804546keywords = connective (Clic here for more details about this article) |
10/142. Silicone granuloma.Since silicone has rapidly become one of the most commonly used prosthetic materials in the last 30 years in modern medicine, we have consequently been witnessing more silicone-related disease. Especially after silicone breast implantation, defects in the breast implant have led to serious complications, whereas complications of silicone prosthesis implantation in other body parts are less frequent. Here we present an unusual clinical presentation of a silicone granuloma in a patient with a 27-year history of a wide excision of a melanoma of the right lower extremity and subsequent soft-tissue reconstruction using a silicone device.- - - - - - - - - - ranking = 0.10589207682793keywords = soft (Clic here for more details about this article) |
