Invasive carcinoma of the cervix in young women.

The cases of 194 women aged 40 years of age or less who had been diagnosed as having invasive cervical cancer in Queensland during 1972-1981 were reviewed retrospectively. Medical records contained a previous cervical cytological report for 89 women, with 18 of these having had a negative result of a smear test within two years of the diagnosis of invasive cancer. Cytological review of five of the 18 cases revealed neoplastic cells in three cases, and possible sampling inadequacies in the other two. Gynaecological symptoms had been present in seven of the 18 patients at the time of the negative result of cytological examination, and these persisted until the diagnosis was eventually made. A high index of suspicion is required when symptoms persist in spite of negative results of cytological examination and we recommend a review of the smear, a repeat smear examination with adequate sampling and referral for colposcopic examination in these circumstances.

Epidermal growth factor: a critical factor in fetal maturation?

Epidermal growth factor (EGF) infused over 3-14 days into fetal sheep of 110-125 days gestation resulted in a number of morphological and endocrine changes. Striking hypertrophy of the skin, wool follicles and their accessory structures was seen, together with a reduction in the ratio of secondary to primary follicles and degenerative changes in wool fibres associated with shedding of fibres. Adrenal, thyroid, liver and kidney weights were increased while thymus weight was decreased. The increase in adrenal size resulted from cortical hypertrophy and was associated with increased cortisol secretion. Thyroid hypertrophy was accompanied by an increase in colloid stores, decreased plasma thyroxine and reverse triiodothyronine (T3) concentrations, unchanged plasma T3 and thyroid-binding globulin and raised thyrotropin (TSH) levels. Thyrotropin receptor affinity and content per gram of tissue were unchanged. Fetal and maternal plasma prolactin and growth hormone levels, and fetal plasma placental lactogen levels, were unchanged, although there was a significant rise in maternal plasma placental lactogen concentrations with high doses of EGF. Other maturational parameters such as switching from fetal to adult haemoglobin and liver glycogen content were unaffected.

Malignant stromal tumour of the ovary with virilizing effects in an XXX female with streak ovaries. Clinical and pathological studies.

In gonadal dysgenesis, the presence of the Y sex chromosome appears to have a strong influence on the development of germ cell tumours. The risk of malignancy associated with other sex chromosomal abnormalities is much lower. In the present report, the clinical manifestations--including primary amenorrhoea, tall stature, infertility and poor development of the genitalia and breasts--associated with a predominantly 47, XXX karyotype are described. Malignant change of the streak ovary to an unusual gonadal stromal tumour with lipid-containing cells occurred at a late stage in her life, and this was associated with progressive virilization and production of androgenic and oestrogenic steroids. In view of the risk of malignancy as well as the abnormal endocrine effects, especially in the presence of a Y chromosome, there is a place for the prophylactic removal of these dysgenetic gonads.

Ectopic vaginal trophoblast in association with a partial mole.

A case of ectopic vaginal trophoblast in association with a blighted ovum showing hydropic degeneration is presented. This combination satisfied the histological criteria of Szulman and Surti for inclusion as a partial mole. Subsequent follow-up revealed non-progression of the condition. The problems of obtaining a satisfactory classification for proliferative trophoblastic lesions are outlined.
