1/47. Expanded polytetrafluoroethylene threads for lip augmentation induce foreign body granulomatous reaction.Especially in cases of facial aesthetic surgery, the demands of the patients are high. The formation of a visible and painful nodule will cause not only discomfort but also dissatisfaction. When alloplastic materials are used for facial and lip augmentation, the possibility of migration, allergic reaction, and formation of a foreign body granuloma is always present. Although e-PTFE is the most bioinert alloplastic material available, the authors could show the formation of a foreign body granuloma. When using e-PTFE threads for facial augmentation, the surgeon should keep in mind and inform the patients that the threads can induce a foreign body granulomatous reaction.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
2/47. Severe migratory granulomatous reactions to silicone gel in 3 patients.In humans implanted with silicone gel breast prostheses, a mild foreign body response results in the formation of a collagenous capsule around the prosthesis. Although many such patients may show evidence of a microscopic granulomatous foreign body reaction upon examination of capsular material at explantation of a prosthesis, it is unusual to have large, palpable granulomas, even in the presence of rupture or leakage. Rare patients have had severe local inflammation and complications resulting from silicone migration to the axilla, arm, or abdominal wall. We describe 3 patients who had deforming granulomas after implant rupture, along with other consequences of silicone gel migrating down the upper extremity. Silicone gel, once it leaves the implant, is not biologically inert and in some persons can elicit profound pathologic responses.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
3/47. Cotton gauze foreign body granuloma following microvascular decompression.We describe a case of a cotton gauze foreign-body granuloma developing 2 months after microvascular decompression for trigeminal neuralgia and hemifacial spasm. This complication has not been previously described. Moreover, the patient's initial clinical and radiological findings were suggestive of an acoustic neuroma or meningioma at the time.- - - - - - - - - - ranking = 28175.009137326keywords = foreign-body (Clic here for more details about this article) |
4/47. Foreign-body granuloma of the kidney: CT, MR and pathologic correlation.The differential diagnosis of renal masses containing fatty foci is limited to a small number of well-defined tumors, angiomyolipoma being the most frequent. In recent years clear cell carcinomas with intratumoral fatty foci have been reported, due to either entrapment of local fat or to regressive adipose metaplasia. Demonstration of focal calcifications is a valuable sign, being relatively common in carcinomas while rare in more benign lesions. We report a case of a foreign-body granuloma of the kidney, containing both calcifications and foci of fat. The value of this case, in our opinion, is that it demonstrates that detection of the previously mentioned features in a renal mass does not necessarily imply a presumptive diagnosis of renal cell carcinoma.- - - - - - - - - - ranking = 28175.009137326keywords = foreign-body (Clic here for more details about this article) |
5/47. Silicone lymphadenopathy mimicking a lymphoma in a patient with a metatarsophalangeal joint prosthesis.With lymph node enlargement, the possibility of a malignant process such as metastatic carcinoma or lymphoma needs to be excluded. This report describes a 47 year old woman with inguinal lymph node enlargement initially suspicious for lymphoma. Fine needle aspiration findings favoured reactive hyperplasia, but a malignant process could not be excluded. The final histological diagnosis was a foreign body granulomatous inflammatory response as a result of regionally disseminated silicone particles from an over looked metatarsophalangeal joint prosthesis. Because of the large number of joint prostheses world wide, it should be kept in mind that migration of wear particles can create granulomatous inflammation and node enlargement.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
6/47. A case of pencil core granuloma with an unusual temporal profile.The patient is a 47-year-old female with a bluish tumor resembling malignant melanoma at the macroscopic level on the medial aspect of her left big toe. The patient had crushed a pencil with this toe about 30 years previously and, since then, a bluish lesion had been present. About 15 years ago, the lesion had suddenly increased in size over the course of a few months. Subsequently, the size of the lesion had not changed noticeably. ultrasonography, but not magnetic resonance imaging was a helpful preoperative examination to distinguish the lesion from malignant melanoma. The excised lesion contained a piece of material that resembled pencil lead and bluish mud. X-ray microanalysis of the lead-like material revealed that its composition was similar to that of pencil lead. Histologic examination showed features of foreign-body reaction, except for necrotic change and few histiocytes.- - - - - - - - - - ranking = 28175.009137326keywords = foreign-body (Clic here for more details about this article) |
7/47. Foreign-body granuloma occurring in the mandible subsequent to orthognathic surgery: a case report.We report the first case of foreign-body granuloma occurring in the mandible of a patient with a history of orthognathic surgery. A 20-year-old male patient had a hard swelling and pain in the left mandibular angle and the parotid area. Plain radiographs showed a radiolucent lesion extending from the buccal area under the left sigmoid notch of the mandible to the mandibular angle. Computed tomographs showed an expanded osteolytic mass in the same area, with destruction of most of the bone on the buccal side. A microscopic examination revealed filamentous foreign material associated with chronic inflammatory cell infiltration and an aggregation of multinucleated giant cells. Foreign-body granuloma in the mandible, although rare, should be included in the differential diagnosis in cases of postoperative masses.- - - - - - - - - - ranking = 28175.009137326keywords = foreign-body (Clic here for more details about this article) |
8/47. Cotton-induced pseudotumor of the femur.Twenty-five years prior to presentation a 41-year-old man had a femoral fracture stabilized with a 4.5 mm AO/ASIF steel plate. The femur healed uneventfully and the patient was asymptomatic for the following 20 years. He then noticed a slow-growing swelling of the left thigh associated with a degree of weakness. Radiographs of the femur 25 years after fracture stabilization showed a massive expansive osteolytic process surrounded by a rim of bone. magnetic resonance imaging (MRI) confirmed the presence of a large tumor. Since malignancy could not be excluded the patient underwent incisional biopsy. The histologic findings were nonspecific. Because of persistent symptoms the lesion was marginally excised. Intraoperatively a folded cotton sponge was found adjacent to the femur. Histopathologic investigation confirmed a foreign body reaction probably related to the retained cotton sponge. Reactive, foreign-body-induced change may mimic bone and or soft tissue malignancies.- - - - - - - - - - ranking = 28175.009137326keywords = foreign-body (Clic here for more details about this article) |
9/47. Silicone migration from silicone-injected breasts: magnetic resonance images.Injection of liquid silicone into the breast was performed illicitly in the 1950s to 1960s and was subsequently prohibited. Many complications arise from silicone injection, and liquid silicone migration is a complication that has not been widely reported. The authors present magnetic resonance images of a patient with liquid silicone migration from the breast to the upper chest and lower neck. breast ultrasonographic and mammographic findings are also presented for correlation.- - - - - - - - - - ranking = 6keywords = migration (Clic here for more details about this article) |
10/47. Complications after meniscal repair with bioabsorbable arrows: two cases and analysis of literature.Biodegradable implants were introduced in the middle 1990s as a new technique for the arthroscopic treatment of reparable meniscal tears. We have used these implants since 1999 and present two cases of failure of biodegradable meniscal repair implants. One foreign-body reaction with granuloma and one fresh meniscus tear after renewed trauma in the case of receding meniscus arrows with a chondral lesion. We also performed a review of the literature with the medline database. Meniscus refixation with bioabsorbable arrows is considered reliable but shows various other complications that must be borne in mind.- - - - - - - - - - ranking = 28175.009137326keywords = foreign-body (Clic here for more details about this article) |
