1/145. Exposure of expanded polytetrafluoroethylene-wrapped hydroxyapatite orbital implant: a report of two patients.

    PURPOSE: Hydroxyapatite (HA) spheres used to replace volume after an enucleation are often wrapped with autologous tissue before orbital implantation. Man-made materials are less expensive and pose no risk for viral transmission. The use of expanded polytetrafluoroethylene (ePTFE) to wrap HA spheres was evaluated. methods: The medical records of 2 consecutive patients who underwent uncomplicated implantation of an HA sphere wrapped in ePTFE were reviewed. RESULTS: An unusual reaction to the ePTFE material that was nonresponsive to topical or systemic antibiotic therapy developed in these 2 patients. Eventual wound erosion and bacterial infection of the implant necessitated its removal. CONCLUSIONS: Although well tolerated in other surgeries, ePTFE, when used to wrap HA spheres and placed into the orbit, may cause persistent conjunctival discharge, pyogenic granuloma formation, and eventual wound erosion. Therefore, the use of this material to wrap HA spheres is not recommended. (+info)

2/145. Cutaneous metastasis from hepatocellular carcinoma resembling pyogenic granuloma.

    A case of skin metastasis from hepatocellular carcinoma (HCC) is reported that resembled pyogenic granuloma. An easily bleeding, cutaneous nodule on the chin of a 62-year-old Japanese male was resected under the diagnosis of pyogenic granuloma. histology, however, indicated HCC. Cutaneous metastases from HCC are very rare, but the possibility must be considered for unusual nodules resembling pyogenic granuloma. (+info)

3/145. aspergillus mycetoma in a secondary hydroxyapatite orbital implant: a case report and literature review.

    OBJECTIVE: The authors describe the first case report of a fungal abscess within a hydroxyapatite orbital implant in a patient who had undergone straightforward secondary hydroxyapatite implant surgery. DESIGN: Case report and literature review. INTERVENTION: Four months postoperatively after pegging and 17 months after original implant placement, chronic discharge and socket irritation became evident. Recurrent pyogenic granulomas were a problem, but no obvious area of dehiscence was present over the implant. The peg and sleeve were removed 31 months after pegging (44 months after original placement of the implant). The pain and discharge did not resolve, and the entire hydroxyapatite orbital implant was removed 45 months after sleeve placement and 58 months after initial implant placement. The pain and discharge settled rapidly. MAIN OUTCOME MEASURES: Cultures and histopathology. RESULTS: Results of bacterial cultures were negative. Results of histopathologic examination of the implant disclosed intertrabecular spaces with multiple clusters of organisms consistent with aspergillus. CONCLUSIONS: Persistent orbital discomfort, discharge, and pyogenic granulomas after hydroxyapatite implantation should cause concern regarding potential implant infection. The authors have now shown that this implant infection could be bacterial or fungal in nature. This is essentially a new form of orbital aspergillus, that of a chronic infection limited to a hydroxyapatite implant. (+info)

4/145. Intravenous pyogenic granuloma mimicking pleomorphic adenoma in a fine needle aspirate. A case report.

    BACKGROUND: Intravenous pyogenic granuloma (IvPG) is a rare, benign lesion occurring usually as a subcutaneous mass in the neck or upper extremity. The cytologic features of IvPG have not been described before. CASE: A patient presented with a subcutaneous nodule on the lower border of the left parotid area. The clinical diagnosis was bronchial cleft cyst or lymphadenitis, and the fine needle aspiration diagnosis was pleomorphic adenoma. The tissue section, however, disclosed IvPG. CONCLUSION: Evaluation of subcutaneous nodules presenting cytologically as spindle cell lesions may be problematic, particularly in the neck and head region. Such lesions occurring in the parotid area may be interpreted as pleomorphic adenoma of the salivary gland. (+info)

5/145. Intravascular fasciitis of the forearm vein: a case report with immunohistochemical characterization.

    Intravascular fasciitis is a very unusual variant of nodular fasciitis. A unique case of this lesion occurring in the proximal portion of the superficial vein of the forearm in an otherwise healthy 26-year-old man is reported. The intravascular polypoid lesion grew longitudinally along the vascular lumen, was loosely attached to the intimal layer, and was partly anchored beyond the internal elastic lamina into the medial smooth muscle layer. However, extravascular involvement was absent. The histological features were identical to those observed in ordinary cellular nodular fasciitis. Because of its myofibroblastic phenotype exhibited by highly proliferative spindle cells, certain intimomedial myofibroblasts are thought to be the indigenous source of this unique fibroproliferative lesion. Unless the diagnosis of intravascular fasciitis is considered and appropriate differential markers examined, it may be confused with other intravascular lesions, such as intravascular leiomyoma, intravenous pyogenic granuloma, organized thrombus and, even, fibromuscular dysplasia if it arises in the arteries. A simple excision is considered curable. Even so, two recurrent cases have been documented to date. (+info)

6/145. Cutaneous lesions of metastatic visceral malignancy mimicking pyogenic granuloma.

    Cutaneous metastases may be the first sign of a previously undiagnosed visceral malignancy or the initial presentation of a recurrent neoplasm. Rarely, skin metastases can resemble a pyogenic granuloma. Three oncology patients who developed new pyogenic granuloma-like cutaneous lesions are described. Histopathologic examination showed metastatic visceral malignancy in the skin. The characteristics of the previously reported cancer patients with metastatic tumor to the skin that mimicked a pyogenic granuloma are reviewed. A biopsy of a skin lesion that clinically appears to represent a pyogenic granuloma should be performed for microscopic examination in patients with a previous visceral malignancy or in cancer-free individuals whose lesions do not resolve after conservative treatment.

7/145. Multiple pyogenic granuloma demonstrated by SPECT using 99Tcm-labelled red blood cells.

    Pyogenic granuloma is a polypoid form of capillary haemangioma that occurs on the skin and mucosal surface. The eruption of multiple pyogenic granuloma is a rare phenomenon. We report the case of a 73-year-old male with a 2 year history of intermittent lower gastrointestinal bleeding. 99Tcm-labelled red blood cell scintigraphy was performed to rule out the possibility of capillary haemangioma on the mucosal surface of the gastrointestinal tract. The images showed disseminated haemangiomas involving the skull, abdominal wall, intestine, scrotum and right leg. The final diagnosis of multiple pyogenic granuloma was made by skin biopsy. To the best of our knowledge, this is the first case using 99Tcm-labelled red blood cell scintigraphy to demonstrate multiple pyogenic granuloma. (+info)

8/145. Case report of a bleeding nasal polyp during pregnancy.

    We report a case of pregnant woman who had a pyogenic granuloma that had caused chronic epistaxis for 1 week's duration. The lesion was excised and the patient recovered fully. (+info)

9/145. Vascular tumors arising in port-wine stains: two cases of pyogenic granuloma and a case of acquired tufted angioma.

    Three female patients affected by intradermal vascular tumors were presented. The lesions were acquired and developed from preexisting port-wine stains (PWS). Among the three patients observed, two had a pyogenic granuloma (PG) and the third patients had tufted angiomas. As reported earlier, formation of a PG within the lesion of a PWS supports the assumption that arteriovenous anastomoses are associated with its pathogenesis. Occurrence of tufted angioma from a PWS, as well as coexisting but separate PWS has been reported. However, the tufted angiomas of our patient were located in different sites, one in the PWS and others separate from the PWS. This has never previously been reported. (+info)

10/145. paronychia with pyogenic granuloma in a child treated with indinavir: the retinoid-mediated side effect theory revisited.

    BACKGROUND: The introduction of hiv-1 protease inhibitors into the treatment of patients infected with hiv-1 has had a major influence on clinical practice. However, the use of protease inhibitors is frequently associated with the development of resistance and several side effects and interactions with other drugs have been reported. OBSERVATIONS: We present the first pediatric patient with paronychia with pyogenic granuloma associated with the administration of the protease inhibitor indinavir. Clinical findings are discussed in view of a possible interference of indinavir with endogenous retinoid metabolism. CONCLUSION: Considerable evidence advocates the mediation of indinavir side effects by impaired oxidative metabolism of retinoic acid through the inhibition of cytochromes P450 3A by indinavir rather than by impaired formation of 9-cis-retinoic acid. copyright (R) 2000 S.
