1/130. Endoscopic preoperative colonic tattooing: a clinical and surgical complication.Endoscopic colonic tattooing is the simplest and most economic technique for identifying small lesions or polypectomy sites during open and laparoscopic surgery. Moreover, it is useful for the endoscopic follow-up of polypectomy sites. india ink is the agent of choice because of its long-lasting stain and the low risk of adverse reaction and toxicity. Very few cases of complications have been reported. We report here the case of a patient in whom colonic tattooing in preparation for surgical resection was followed by clinical complications such as fever and abdominal pain. An abscess-type inflamed pseudotumor was found at laparotomy. Histological examination revealed chronic granulomatous inflammation.- - - - - - - - - - ranking = 1keywords = granuloma (Clic here for more details about this article) |
2/130. Extraorbital inflammatory pseudotumor of the head and neck: CT and MR findings in three patients.We review the clinical history and imaging (CT and/or MR) studies in three patients with histologically proved extraorbital inflammatory pseudotumor of the head and neck. The imaging findings in all three cases were nonspecific, mimicking a malignant tumor or granulomatous disease.- - - - - - - - - - ranking = 1keywords = granuloma (Clic here for more details about this article) |
3/130. Inflammatory myofibroblastic tumor of the skin.We report a case of inflammatory myofibroblastic tumor (IMF) of the skin in a female with a history of Wegeners granulomatosis. The patient had a painless, erythematous, and indurated lesion of the left elbow. The resected specimen revealed a 4 cm x 3 cm nodule involving the entire dermis and superficial portions of subcutis with a stellate profile at scanning magnification. There were spindle cells in fascicles and whorls and a mixed inflammatory cell infiltrate of plasma cells, lymphocytes, neutrophils, and eosinophils. The spindle cells were immunoreactive for vimentin, muscle specific actin, and smooth muscle actin. The polyclonal and polymorphous nature of the inflammatory cells was confirmed by immunohistochemical studies. This is the first case of IMF of the skin documented by immunostaining.- - - - - - - - - - ranking = 1keywords = granuloma (Clic here for more details about this article) |
4/130. Multifocal omental mesenteric inflammatory pseudotumor (plasma cell granuloma).Inflammatory pseudotumor (IP) is an uncommon benign tumor during childhood. The most common location is lung, and sporadic cases of IP with extrapulmonary involvement such as liver and abdomen are reported. However, the IP among the reported cases have appeared as solitary masses. A multifocal IP in a 14-year-old girl presumed to result following an entamoeba histolytica infestation is reported.- - - - - - - - - - ranking = 4keywords = granuloma (Clic here for more details about this article) |
5/130. Plasma cell granuloma of the oral mucosa with angiokeratomatous features: a possible analogue of cutaneous angioplasmocellular hyperplasia.We report a plasma cell granuloma arising in the movable mucosa of the oral cavity of a 50-year-old man. Histologically, the lesion was characterized by a dense nodular infiltrate of mature plasma cells. Immunostaining for kappa and lambda light chains confirmed a polyclonal plasma cell population. Elongated rete ridges of the overlying epithelium formed collarettes around dilated blood and lymph vessels in focal areas. Based on the overall histologic architecture, we hypothesize that these peculiar changes are secondary to local blood flow alteration with congestive vasodilation caused by a dense plasma cell infiltrate. We believe that the plasma cell population may represent the oral counterpart of the cutaneous angioplasmocellular hyperplasia.- - - - - - - - - - ranking = 5keywords = granuloma (Clic here for more details about this article) |
6/130. Sclerosing inflammatory myofibroblastic tumour of the tongue: an immunohistochemical and ultrastructural study.A case of inflammatory myofibroblastic tumour (IMT) arising in the tongue of a 27-year-old man is described. The patient presented with a solitary, well-circumscribed submucosal mass of 4 months duration. The tumour showed in its largest part a paucicellular sclerosing lesion resembling a hyalinizing granuloma surrounded by a thin rim of an admixture of myofibroblasts, plasma cells and foamy histiocytes. myofibroblasts expressed vimentin and alpha-smooth muscle actin positive immunophenotypes. Ultrastructurally the hyaline areas were composed of abundant collagen fibres with sparse myofibroblasts. Extensive scar-like change in this IMT may be related to a traumatic insult.- - - - - - - - - - ranking = 1keywords = granuloma (Clic here for more details about this article) |
7/130. Rapid recurrence of an inflammatory myofibroblastic tumor in the right ventricular outflow tract.We describe an unusual case of rapid recurrence of a previously excised inflammatory myofibroblastic tumor of the right ventricular outflow tract in a 5-month-old infant. The infant is asymptomatic 18 months after the second surgery. The very rare cardiac involvement, and the early relapse of the inflammatory pseudotumor, to the best of our knowledge, is a unique combination. The inflammatory myofibroblastic tumor, as known as a pseudotumor or plasma cell granuloma is an uncommon reactive lesion with unknown aetiology. It is found most commonly in the lung and a number of visceral organs, such as the spleen, liver, ileum, salivary glands, urinary bladder, larynx or brain or in the retroperitoneum and lymph nodes. To our knowledge only 9 cases have been published of such tumor arising within the heart.- - - - - - - - - - ranking = 1keywords = granuloma (Clic here for more details about this article) |
8/130. Plasma cell polyp of the vocal fold.Plasma cell polyps of the vocal fold (plasma cell granulomas) are rare inflammatory polyps of the larynx. They should be included in the clinical and histological differential diagnosis of laryngeal polyps. Histologically they are polyclonal aggregates of plasma cells. It is essential to distinguish them from monoclonal, neoplastic plasma cell proliferations. The treatment of choice is surgical resection, although radiotherapy, laser ablation, antibiotics and steroids have been used successfully. We present a case of plasma cell granuloma presenting as a vocal fold polyp, treated surgically.- - - - - - - - - - ranking = 2keywords = granuloma (Clic here for more details about this article) |
9/130. A case of hemangioma accompanied by inflammatory pseudotumor of the spleen.Both hemangioma and inflammatory pseudotumor (IPT) of the spleen are rare benign mass lesions. Moreover, a splenic hemangioma accompanied by IPT is extremely rare. A 61-year-old woman who suffered from liver cirrhosis had a splenic cavernous hemangioma surrounded by granuloma. The literature on IPT of the spleen has described several possibilities of its causes; however, it is still unknown. This case was accompanied by portal hypertension due to liver cirrhosis, which may cause microrupture of hemangioma resulting in an IPT.- - - - - - - - - - ranking = 1keywords = granuloma (Clic here for more details about this article) |
10/130. Inflammatory pseudotumor of the alimentary tract: clinical and surgical experience.BACKGROUND/PURPOSE: Initially described in 1937, inflammatory pseudotumor (IPT) inflammatory myofibroblastic tumor (IMT) or plasma cell granulomas are synonymous for an inflammatory solid tumor that contains spindle cells, myofibroblasts, plasma cells, and histocytes. Common sites of presentation include lung, mesentary, liver, and spleen; intestinal presentations are rare, and the etiology remains obscure. This report details the clinical and surgical experiences in 4 children with alimentary tract IPT at a single institution. methods: A retrospective chart review was conducted of pediatric patients with the pathologic diagnosis of IPT. RESULTS: Between 1990 and 1999, 4 patients (4 girls, ages 5 to 15 years) were identified with gastrointestinal tract origins of IPT. Symptoms at presentation included anemia (n = 4), intermittent abdominal pain (n = 3), fever (n = 3), weight loss (n = 2), diarrhea (n = 2), dysphagia (n = 1). Two patients had comorbid conditions of juvenile rheumatoid arthritis and mature B cell lymphoma. Three of 4 patients had elevated sedimentation rates. The sites of origin were the gastroesophageal junction, the colon, the rectum, and the appendix, with the referral diagnosis achalasia, perforated appendix, inflammatory bowel disease, and recurrent lymphoma, respectively. All were treated with aggressive surgical resection, and 3 girls have had no recurrences since the initial surgery. One patient had 3 recurrences within 8 months of presentation; she remains disease free 8 years later. CONCLUSIONS: IPT, although rare in the gastrointestinal tract, mimics more common problems. Successful surgical management is possible even in cases of multiple recurrences.- - - - - - - - - - ranking = 1keywords = granuloma (Clic here for more details about this article) |
