1/84. Neuro-ophthalmologic manifestations of a paraneoplastic syndrome and testicular carcinoma.

    The authors report two patients with testicular cancer who exhibited supranuclear gaze disorders as a manifestation of a paraneoplastic brainstem encephalomyelitis. In the first patient, neuro-ophthalmic dysfunction was accompanied by a prominent limbic encephalitis whereas in the second patient, an unusual, mixed pendular and jerk nystagmus was manifested. neuroimaging revealed an enhancing hypothalamic mass in the first patient and was negative in the second. Blood from both patients contained an antibody previously reported in a patient with limbic encephalitis and testicular cancer.

2/84. seminoma associated with bilateral cryptorchidism in Down's syndrome: a case report.

    BACKGROUND: A case of testicular typical seminoma associated with bilateral undescended testes in Down's syndrome is reported. A 42-year-old institutionalized male patient developed left testicular seminoma with retroperitoneal metastasis. methods/RESULTS: Neither adjuvant chemotherapy nor radiotherapy were performed due to his severe mental retardation. He died as a result of the cancer 2 years after a left radical orchiectomy and an autopsy was carried out. DISCUSSION: Recently an increase in the incidence of the association of testicular tumors and Down's syndrome has been repeatedly documented. Thirty-six cases of testicular tumors associated with Down's syndrome have been reported and of these 17.1% had cryptorchidism. This is a much lower percentage considering the high risk of cryptorchidism in males with Down's syndrome. The relationship between testicular germ cell tumors associated with cryptorchidism and Down's syndrome is discussed.

3/84. Hereditary TP53 codon 292 and somatic P16INK4A codon 94 mutations in a li-fraumeni syndrome family.

    li-fraumeni syndrome is an autosomal dominant disorder that is characterized by various types of cancer in childhood and adult cases. Although hereditary TP53 mutation is very rare in different human cancers, it has been frequently reported in li-fraumeni syndrome. On the other hand, hereditary mutations of TP57KIP2, P15INK4B, and P16INK4A, which affect the cell cycle similar to TP53, were observed in some types of cancer. In a Turkish family with the diagnosis of li-fraumeni syndrome, we analyzed the mutation pattern of TP53, P57KIP2, P15INK4B, and P16INK4A in the peripheral blood, and loss of heterozygosity (homo/hemizygous deletion) pattern of TP53 and P15INK4B/P16INK4A in two tumor tissues. The propositus had a seminoma, his daughter a medulloblastoma, and one of his healthy cousins, a TP53 codon 292 missense point mutation (AAA-->ATA; Lys-->Ile) in the peripheral blood cells. Tumor tissue obtained from the propositus with the seminoma revealed loss of heterozygosity in the TP53 gene. In the analyses of tumor tissues from the propositus and his daughter, a P16INK4A codon 94 missense point mutation (GCG-->GAG; Ala-->Glu) was observed with the hereditary TP53 mutation. P16INK4A codon 94 mutation observed in our family is a novel mutation in li-fraumeni syndrome. No other gene alteration in TP53, P57KIP2, P15INK4B, and P16INK4A was observed. Existence of the P16INK4A mutation and the hereditary TP53 mutation with or without loss of heterozygosity in the TP53 gene (seminoma/medulloblastoma) may be evidence for a common mechanism involved in tumorogenesis. The gene alterations in TP53 and P16INK4A genes may be used as tumor markers in our family.

4/84. seminoma in a 31-year-old patient on long-term growth hormone therapy.

    We describe a Caucasian male patient aged 31, who was referred to the Institute of reproductive medicine because of infertility and androgen deficiency and in whom we incidentally diagnosed a unilateral testicular tumor. The patient had received growth hormone (GH) since the age of 8 years. One case presenting with testicular neoplasm under growth hormone substitution has been described previously. In conclusion, it cannot be ruled out that GH treatment may be involved in the pathogenesis of germ cell tumor development. Special care should be exercised when patients with a history of maldescended testes require GH substitution. This care should include regular testicular ultrasonography at e.g. half-yearly intervals since sonography may detect testicular tumors long before they become clinically apparent.

5/84. Postirradiation aortic sarcoma demonstrated by magnetic resonance angiography.

    This is the first ever reported case of a radiation-induced aortic sarcoma. This patient had symptoms and signs initially interpreted as a pulmonary embolus. The extent of the disease was demonstrated with magnetic resonance imaging and magnetic resonance angiography, in particular, allowing rapid surgical intervention.

6/84. scleromyxedema: possible association with seminoma.

    Although scleromyxedema has been associated with neoplasm in rare instances, the literature showed no evidence of association with seminoma. We report a 43-year-old man who presented with a scleromyxedema and relapsed seminoma. The skin lesions of scleromyxedema cleared completely on treatment of seminoma with chemotherapy.

7/84. Malignant peritoneal mesothelioma associated with deep vein thrombosis following radiotherapy for seminoma of the testis.

    A 52-year-old man developed malignant peritoneal mesothelioma 17 years after radiotherapy for seminoma of the testis. Although asbestos exposure is considered to be the major risk factor for the development of malignant mesothelioma, prior therapeutic radiation has also been postulated as a causative factor. The unexplained appearance of ascites or pleural effusion within a previously irradiated area should be considered suggestive of malignant mesothelioma in any long-term survivor of cancer. In addition, the patient suffered a deep vein thrombosis four years before the diagnosis of mesothelioma. Deep vein thrombosis is a common complication of malignant disease, and is often the first clue to occult malignancy.

8/84. Synchronous appearance of germ cell tumor and papillary carcinoma of the thyroid.

    Synchronous appearance of 2 different malignancies in one patient is a rare phenomenon. We describe our experience of 2 patients with synchronous malignancies of the testis and thyroid gland, and of a third patient who developed a thyroid neoplasm unrelated to recent treatment for a germ cell tumor. The medical records of 3 male patients treated for both a germ cell tumor and a thyroid cancer between 1989 and 1994 were reviewed. Two patients with nonseminomatous germ cell tumor received postoperative chemotherapy after orchiectomy and developed a papillary carcinoma of the thyroid during treatment. A third patient, who received radiation therapy for a clinical stage 1 seminoma, recurred with biopsy proven seminoma in the neck in association with a thyroid nodule 2 years later. All 3 patients had their thyroid cancer treated by surgical resection, and one received adjuvant radioactive iodine. Two of the patients are currently alive and disease-free. One patient died of pulmonary complications that stemmed from bleomycin toxicity. Synchronous appearance of germ cell tumor and papillary carcinoma of the thyroid has not been previously described. Genetic predisposition may play a role in the development of such simultaneous neoplasms.

9/84. Primary retroperitoneal seminoma with utrasonically abnormal testes.

    Primary retroperitoneal seminomas account for approximately 2% of all seminomas. Differentiating the primary retroperitoneal tumor from a metastatic tumor with an occult testicular primary remains difficult despite the availability of ultrasonic examination. We present a case of primary retroperitoneal seminoma with ultrasonically demonstrated abnormalities in both testes. The patient underwent a unilateral orchiectomy and ultrasound-guided biopsy of the opposite testis. All surgical specimens were negative for testis cancer. Controversial issues in the diagnosis and treatment of primary retroperitoneal germ cell tumors are discussed.

10/84. Paraneoplastic limbic encephalitis, a complication of the testicular cancer.

    We report a case of paraneoplastic limbic encephalitis related to a testicular neoplasm. The syndrome is characterized by progressive amnesia and psychiatric disturbances resulting from an inflammatory reaction probably related to an immune response to the neuronal proteins expressed by tumors. It is usually associated with small cell lung cancer. In other cases, testicular cancer occurs more frequently than expected. Cranial magnetic resonance imaging may show increased signal intensity in the limbic cortex. Genitourinary examinations are sometimes inadequate. Testicular ultrasonography is recommended if no tumor is detected on the chest and abdominal computed tomography scan. The outcome of the treatment of the testicular cancer on the paraneoplastic syndrome is variable.
