1/5831. Intra-articular metastatic melanoma of the right knee.

    melanoma can metastasize to almost every organ and tissue. Although bone metastases have been reported frequently, the authors are aware of only a single report of intra-articular synovial metastasis. A case of metastatic melanoma, mimicking degenerative medial meniscal tear of the right knee, is presented. Further examination revealed asymptomatic metastases in the liver, subcutaneous tissue, and left trochanter minor. Arthroscopic examination revealed widespread synovial metastasis and a palliative arthroscopic synovectomy was performed. ( info)

2/5831. liver metastases from extremity soft tissue sarcoma.

    liver involvement by soft tissue sarcoma is an unfavorable prognostic factor for survival. Complete resection of liver metastases can bring improvement in selected patients, but chemotherapy remains the only palliative treatment option for most. Anecdotal long-term survival of patients with unresectable liver metastases treated with systemic chemotherapy has been reported, such as the patient presented here. ( info)

3/5831. Endobronchial brachytherapy for recurrent thymoma showing endobronchial polypoid growth.

    The authors report a case of recurrent thymoma displaying endobronchial polypoid growth. Initially, the patient had invasive thymoma with intracaval growth into the right atrium. He was treated with multimodality therapy consisting of chemotherapy, surgical resection, and radiotherapy (50.4 Gy). Both 3 years and 6 years after the initial treatment, the tumor recurred outside the reconstructed superior vena cava. The patient was treated with repeated radiotherapy (50.4 Gy and 40 Gy), and remission was achieved. Eight years after the first therapy, an endobronchial polypoid lesion was detected in the right upper lobe bronchus and was histologically found to be thymoma. Endobronchial high-dose rate brachytherapy (20 Gy at 3 mm/5 fractions) was carried out for palliation because the recurrent tumor occurred outside of the superior vena cava area, which had been reirradiated. After the treatment, the endobronchial tumor shrunk remarkably in size without adverse effects. No tumor regrowth has been noted after a follow-up of 10 months. ( info)

4/5831. Surgical management of pediatric tumor-associated epilepsy.

    brain tumors are a common cause of seizures in children. Early surgical treatment can improve seizure outcome, but controversy exists regarding the most appropriate type of surgical intervention. Some studies suggest tumor resection alone is sufficient, while others recommend mapping and resection of the surrounding epileptogenic foci to optimize seizure outcome. To address this issue, we reviewed the charts of 34 pediatric patients aged 18 months to 20 years with medically intractable epilepsy and primary brain tumors. The average age at operation was 12.6 years, and patients had seizures for an average of 6.4 years. The majority of tumors were located in the temporal lobe. Seventeen patients, because of tumor location near an eloquent area, underwent extraoperative mapping using subdural electrode grids prior to definitive tumor resection. Fourteen of these patients had a gross total tumor resection, yet only two had a distinct zone of ictal onset identified and resected. The remaining 17 patients had tumors either in the nondominant hemisphere or far removed from speech-sensitive areas, and therefore did not undergo extraoperative subdural electroencephalograph mapping. Fourteen of these patients also had a gross total tumor resection, while none had intraoperative electrocorticography to guide the resection of additional nontumoral tissue. overall, of the 28 patients treated with a gross total tumor resection, 24 (86%) are seizure free, while the other four are significantly improved. Of the six patients who had a subtotal tumor removal, five have persistent seizures. The mean follow-up was 3.6 years. We conclude that in children and adolescents, completeness of tumor resection is the most important factor in determining seizure outcome. The routine mapping and resection of epileptogenic foci might not be necessary in the majority of patients. As a corollary, the use of subdural electrode grids in pediatric patients with tumor-associated epilepsy should be limited to cases requiring extraoperative cortical stimulation for localization of nearby eloquent cortex.

5/5831. Recurrent malignant proliferating trichilemmal tumour: local management with ethanol injection.

    We report a 59-year-old woman who exhibited a recurrent malignant proliferating trichilemmal tumour on the scalp for 1 5 years. The tumour was recalcitrant to conventional treatments such as chemotherapy, radiation or hyperthermia and we performed intratumoral ethanol injection as an alternative means of reducing tumour mass and obtaining haemostasis. biopsy specimens obtained after the ethanol injection revealed oedema, haemorrhage in the dermis and degeneration of the tumour cells, showing vacuolization with pyknotic nuclei. For cases of recurrent skin tumours and for patients in poor clinical condition, intratumoral ethanol injection is likely to be a therapeutic alternative to surgery or other conventional treatments.

6/5831. Acral dermatofibrosarcoma protuberans with metastases.

    dermatofibrosarcoma protuberans (DFSP) is an uncommon cutaneous tumor that occurs rarely on the extremities. This tumor has a particular propensity for local recurrence following seemingly adequate excision. Metastases are rare, and usually follow repeated local recurrences. On rare occasions, fibrosarcomatous change may arise in a DFSP, and appears to affect adversely the prognosis. The adequacy of the initial resection is the most important prognostic factor; however, suggested margins vary between 1.5 and 5 cm. The ideal margin of resection on the foot is unknown. We report a patient with recurrent, acral DFSP with fibrosarcomatous change and pulmonary parenchymal metastases in a 48-year-old black male. ( info)

7/5831. Cranio-orbital-temporal neurofibromatosis: are we treating the whole problem?

    Cranio-orbital-temporal neurofibromatosis is an uncommon subtype of neurofibromatosis 1 characterized by pulsatile exophthalmos, orbital neurofibromas, sphenoid wing dysplasia, expansion of the temporal fossa, and herniation of the temporal lobe into the orbit. The cause of the sphenoid wing dysplasia is uncertain. Reconstruction of the sphenoid defect, separating the orbit and cranial vault, has been problematic because of resorption of bone grafts. This reports illustrates one potential cause of the sphenoid defect and a possible cause of the bone graft resorption. ( info)

8/5831. The effectiveness of chemotherapy with cisplatin and 5-fluorouracil for recurrent small cell neuroendocrine carcinoma of the rectum: report of a case.

    We report herein the case of a 46-year-old-man with small cell neuroendocrine carcinoma (NEC) concomitant with large villous adenoma of the rectum, who underwent abdominoperineal resection with regional lymphnode dissection. The resected specimen was histologically found to contain a small lesion of NEC confined to the submucosa in the large adenoma. A computed tomography scan done 4 months postoperatively revealed recurrences in the liver, lymph nodes, and bone. Therefore, two cycles of sequential intravenous combined chemotherapy with standard doses of cisplatin and 5-fluorouracil (5-FU) were administered, after which the size of each tumor decreased remarkably. Nevertheless, the patient died 8 months after the operation. As there was a fair response of this tumor to the combined chemotherapy of cisplatin and 5-FU, this regimen against NEC of the colon and rectum should be given consideration. ( info)

9/5831. Basal cell carcinoma of the eyelids: a review of patients treated by surgical excision.

    A study of 107 cases of basal cell carcinoma involving the eyelids in 106 patients all treated by surgical excision was undertaken. The lesions were found predominantly in Caucasians, showed no sex predilection (except for the fact that all five cases under age 40 occurred in females), and were most prevalent in the 7th decade of life. The most common presenting symptom was a mass or growth, while the duration of symptoms of any kind referable to the tumor was 20 months. The lower lid was the most common site of involvement, followed in order of frequency by the upper lid, medial canthus, and lateral canthus. Excised lesions that show marginal involvement histopathologically will not necessarily clinically recur, although this study did show that incomplete excision will more likely show a clinical recurrence in previously treated rather than primary lesions. If basal cell carcinomas of the eyelid are fully surgically excised as a first procedure, the patient will have about a 99% cure rate. Lesions requiring orbital exenteration are rare. ( info)

10/5831. Ovarian endometrioid-like yolk sac tumor treated by surgery alone, with recurrence at 12 years.

    We describe the case of a stage Ia endometrioid-like yolk sac tumor (YST) of the ovary, which was originally misdiagnosed as a malignant struma ovarii and not treated with adjuvant chemotherapy. After 12 years, a contralateral dermoid cyst was excised along with a small omental nodule of partially necrotic and calcified endometrioid-like YST. No tumor was detected in several other biopsy specimens, and a peritoneal lavage was negative for tumor cells. Since there was no evidence of remaining tumor and the serum alpha-fetoprotein (AFP) level was normal after the second operation, the patient was followed. Serial serum AFP levels remained normal for 4 months. At a second-look laparotomy after 4 months, a small tumor nodule was removed from the cul-de-sac. Postoperatively, the patient received three cycles of BEP chemotherapy. The long disease-free interval after the first operation in spite of the presence of occult spread to the omentum and to the pouch of Douglas in this case indicates that some endometrioid-like YSTs may have an indolent course. The present case underscores the importance of careful surgical staging and of long-term follow-up in cases of primitive germ cell tumors of the ovary. ( info)
