1/51. Epignathus: a germ-cell tumour presenting as neonatal respiratory distress.

    A full-term neonate developed acute upper airway obstruction immediately after birth secondary to a polypoidal mass in the oropharynx. After the child's airway had been secured, the mass was excised and found to be a nasopharyngeal teratoma, a rare congenital germ cell tumour which is frequently associated with other congenital malformations. It is sometimes possible to diagnose these tumours in utero, thereby enabling appropriate precautions to be taken during the delivery, otherwise if the diagnosis is unknown, then it is essential for any attending clinician to urgently secure the airway by means of either intubation or tracheostomy. Such a case is presented with a review of the possible management options. This case emphasises the fact that although many conditions are uncommon, the total incidence of rare conditions is surprisingly high, and that care needs to be taken at all times in the management of patients, in order not to overlook such life-threatening diagnoses.

2/51. eustachian tube teratoma and its terminological correctness.

    Teratomas are germ cell tumours usually found in the young and are characteristically composed of tissue foreign to the place where they arise. Two teratomas of the middle ear were first described in 1866 and since then, and to the best of our knowledge, 19 additional cases have been reported in the literature under different terms such as hairy congenital polyps, epidermoid cysts, dermoid cysts, hamartoma, cutaneous teratoma and teratomas. The difficulty in classifying germ cell tumours may explain the different terminologies encountered in the literature. The authors describe a case of teratoma of the eustachian tube presenting as a mass in the middle and external ear of a 10-week-old girl. Using this case, a review of the literature is performed in light of the new classification of germ cell tumours proposed by the world health organization (WHO). It is of note that most of the teratomas that present in the middle ear arise from, or involve, the eustachian tube.

3/51. Conversion of multiple solid testicular teratoma metastases to fatty and cystic liver masses following chemotherapy: CT evidence of "maturation".

    Testicular germ cell tumour metastases may undergo "retroconversion" to mature differentiated teratoma following chemotherapy or irradiation. We report a patient with testicular germ cell liver metastases in whom computed tomography (CT) scans following chemotherapy demonstrated a reduction in CT attenuation of the liver lesions to that of cystic and fatty density. This is believed to represent CT evidence of liver metastasis "retroconversion", which offers the potential for non-invasive monitoring of histological progression.

4/51. Ruptured granulosa cell tumor of the left ovary and mature cystic teratoma of the right ovary: a case report of unusual acute abdominal syndrome.

    Although granulosa cell tumor combined with a dermoid cyst in the same ovary is rarely seen, adult granulosa cell tumor of the ovary with contralateral teratoma has not been reported to date. In this report we present the first case in the English language literature of a ruptured granulosa cell tumor of the left ovary and mature cystic teratoma of the right ovary presenting as acute abdominal syndrome. The patient underwent total abdominal hysterectomy, bilateral-ophorectomy, and multiple pelvic lymph node sampling and infracolic omentectomy. She received combined chemotherapy consisting of bleomycin, etoposide. and cisplatin for six cycles. Subsequent follow-up and workups have revealed no evidence of disease. At 19 months after initial diagnosis, she is disease-free.

5/51. Teratocarcinosarcoma of the nose, paranasal sinuses and nasopharynx.

    Teratomas affecting the head and neck are rare tumours of ambiguous origin. The benign form is seen in children and mostly affects the nasopharynx. Malignant tumours in the upper jaw have been reported rarely. They are almost exclusively seen in the adult male. They are highly aggressive tumours that are difficult to diagnose pre-operatively due to the varied histological patterns. Treatment options available are surgery, radiotherapy or a combination of both. Despite intensive treatment, the prognosis is still poor. A rare case of teratocarcinosarcoma of the nose, paranasal sinuses and nasopharynx in a 25-year-old male is presented. The tumour had a non-germ cell tumour origin. The clinical features, pathologic characteristics and treatment are detailed. It was managed by surgery, radiotherapy and chemotherapy.

6/51. Germ cell neoplasms in three intersex patients with 46,XY karyotype.

    This report presents 3 cases with gonadoblastoma mixed with other germ cell tumours in intersex patients, all with a 46,XY karyotype. One 11-year-old patient was a true hermaphrodite, the others, aged 13 and 18, respectively, had both gonadal dysgenesis. Different clinical courses have been noted. Two patients had gonadoblastoma combined with dysgerminoma; in one of them a teratoma was also found. In the third case gonadoblastoma was transformed into teratocarcinoma. The malignant degeneration was more serious in the 2 pubertal patients. Thus, we recommend early and prophylactic gonadectomy.

7/51. The association of germ cell tumours of the testis with sarcoid-like processes.

    Sarcoid-type pulmonary lymphadenopathy associated with testicular cancer is a rare condition which has been previously reported in only 14 cases. Earlier case reports have failed to distinguish between generalized sarcoidosis as opposed to a local granulomatous reaction to tumour. We describe a further 8 cases of the association and provide strong supportive evidence for systemic sarcoidosis in 5 of our patients. In 3 of our patients with systemic sarcoidosis there was coexisting testicular cancer requiring additional treatment. We therefore advise caution in the interpretation of the clinical and histological findings in these patients, and recommend thorough investigation of all such cases.

8/51. The changing role of surgery in metastatic non-seminomatous germ cell tumour.

    In the last 2 years (1989-1990) we have treated a total of 53 patients with metastatic nonseminomatous germ cell tumours (teratoma). In ten cases surgery to remove residual abdominal masses was required on completion of chemotherapy and normalisation of tumour markers (HCG and AFP). In a further three patients with large intra-abdominal masses and little or no other sites of disease surgery was performed as a therapeutic intervention, in the context of plateauing or rising tumour markers despite intensive chemotherapy. In all three, this approach resulted in a rapid fall in tumour markers, and following further chemotherapy all three remain disease free at 7, 12 and 25 months. For this small sub-group of patient failing to respond to chemotherapy who have resectable lesions, interventional surgery should be considered as part of a combined approach to treatment.

9/51. Infected teratodermoid tumour of the mediastinum.

    Teratomas of diverse sites in infants and children have been seen in this institution, but this is the first primary germ-cell tumour of the mediastinum in a child reported from Northern nigeria. The patient had an infected teratodermoid tumour of the mediastinum which was erroneously diagnosed as chronic empyema thoracis.

10/51. Intracardiac metastases from germ cell tumours--an unusual but important site of metastasis.

    Two cases of intracardiac deposits from testicular teratomas diagnosed by echocardiography and angiocardiography, respectively, are described. The importance of recognizing this as an uncommon site of metastasis from germ cell tumours is discussed.
