Extrauterine mesodermal (müllerian) adenosarcoma. A case report.

Extrauterine mesodermal (müllerian) adenosarcomas have only recently been described, and this is the first reported case from Australia. These tumours fall within the category of common epithelial tumours' in the World Health Organisation (W.H.O.) classification of ovarian tumours and comprise benign looking epithelial structures (glands, papillae) in association with sarcomatous stroma. They are thus distinct from malignant mesodermal mixed tumours in which both epithelial and stromal elements are cytologically malignant.

Malignant melanoma metastases in the placenta: a case report.

Although the coincidence of pregnancy and maternal malignancy is not rare, only 29 cases of metastases to the products of conception have been previously reported and of these, 14 have been of malignant melanoma. The present case of widespread maternal malignant melanoma metastasizing to the placenta further emphasizes this trend. The mother died of malanomatosis two weeks after induced labour at 36 weeks gestation. The infant, despite widespread placental involvement including apparent foetal vascular invasion, is well and without clinical evidence of disease five months after delivery.

Clear cell adenocarcinoma of the uterine cervix: a histological and histochemical study.

A case of Mullerian clear cell adenocarcinoma of the uterine cervix occurring in a young women is presented. A detailed histological and histochemical study of this type of tumour is important so as to separate it from the clear cell tumour of mesoenphric origin. The association of Mullerian clear cell adenocarcinoma and other abnormalities of the vagina and cervix with the administration of maternal nonsteroidal oestrogens has been recently stressed in the literature. However, our patient is illustrative of the 30-50% of cases reported to date which have few if any of the associated abnormalities of the genital tract and have no known exposure to non-steroidal oestrogens.

Uterine fibroid: an unusual cause of recurrent haemorrhagic pleural effusion.

A 51-year-old woman presented with dyspnoea due to pleural effusion, which repeatedly reaccumulated rapidly after tapping. A pelvic mass was present and she was considered to have disseminated ovarian malignant tumour. Total hysterectomy with bilateral salpingo-oophorectomy was performed, and the tumour was shown to be a necrotic uterine fibromyoma. After the operation the patient has been well, with no recurrence of the effusion. This is the twelfth reported case of the association of hydrothorax with uterine fibromyoma, and is a form of the rare pseudo-Meigs' syndrome.

Adenovirus infection of the cervix.

A case is recorded in which intranuclear inclusions suggesting adenovirus infection were recognized in a routine Papanicolaou smear. The patient was recalled for virologic studies and adenovirus type 19 was cultured from the cervix. The patient had a recent history of systemic illness with conjunctivitis, and a friend had conjunctivitis at the same time which was also proven to be due to adenovirus of the same serotype. This is the first reported instance in which adenovirus infection of the cervix suspected on cytologic findings has been confirmed by virus culture.

Electron microscopic detection of papilloma virus particles in selected koilocytotic cells in a routine cervical smear.

A routine cervical smear from a 56-year-old postmenopausal woman showed appearances indicative of papilloma virus infection with atypia. In an attempt to prove the diagnosis, the smear was reprocessed for electron microscopic examination. The reprocessing technique is described. Ultrastructural preservation was poor, and significant shrinkage was observed. In spite of these technical difficulties it was possible to prove that the selected cells in the smear contained papilloma virus particles. The virus particles seen were intranuclear in location and spherical in shape with a diameter of 40 to 50 nm. As was demonstrated in this case, the technique described will prove useful in evaluating the reliability of various diagnostic criteria for identifying viral infections in routine smears. This will apply particularly in cases where cultural confirmation of a reported viral infection is not possible.

The significance of noncondylomatous wart virus infection of the cervical transformation zone. A review with discussion of two illustrative cases.

The clinicopathologic features are described of two patients whose cervical cytology smears showed features which were thought initially to indicate dysplasia, but which were later considered to be those of condylomata acuminata. One patient was an immunosuppressed renal transplant recipient, the other was a routine gynecologic clinic patient. No condylomas were recognizable clinically, and colposcopy showed only a flat but atypical transformation zone. Biopsy in each case showed a noncondylomatous warty lesion and wart virus particles were demonstrated by electron microscopy. These cases highlight the clinical, colposcopic, cytologic and histologic diagnostic difficulties which are encountered with cervical transformation zone wart virus infections, which are commoner than formerly realized. The possible relationship of wart virus infection to cancer of the cervix is also discussed.
