The usefulness of limited placental sampling in stillbirths

Malays J Pathol, 1998 Dec;20(2):99-102.

144 placentas were sampled from all cases of stillbirth weighing 500 g and above seen over a period of thirteen months in the UKM Unit of the Maternity Hospital, Kuala Lumpur. Sampling was limited to 1-3 blocks per placenta for histological study. Placental abnormalities were found in 121 (85%) placentas, 78 of which had definite lesions known to contribute to foetal death while the remainder showed lesions suggestive of an underlying disease. This study supports the usefulness of limited sampling of the placenta in the face of unavailability of complete placental examination and autopsy for assessment of the cause of stillbirth.

INTRODUCTION: Chronic histiocytic intervillositis (CHI) is a rare placental lesion strongly associated with recurrent miscarriages and fetal losses. It requires histopathological diagnosis and can only be made after delivery of the products of conception (POC). We describe a case of CHI in a 41-yearold lady with a 16-year history of thirteen recurrent consecutive first trimester miscarriages.

CASE REPORT: The patient is a 41-year-old lady who suffered first trimester miscarriages in all her thirteen pregnancies. The relevant clinical investigations revealed neither significant nor helpful findings in determining the cause of recurrent miscarriages. Histological findings in each except one of the submitted conceptual tissue showed similar features of histiocytic aggregates primarily within the intervillous spaces, a characteristic description of CHI. One of the samples showed degenerative changes.

DISCUSSION: Practicing pathologists are not familiar with the histological features of CHI and this may be a potential pitfall in routine examination of POCs. Recognising this entity allows for accurate diagnosis and hence better management. The aetiology remains unclear, although an immunopathological basis are being explored.

Fulltext Maternal melanoma with placental metastasis

A 40-year-old woman, a grand multipara with uncertain gestation, presented with severe, prolonged diarrhoea. She was previously diagnosed to have melanoma. Examination revealed gross ascites with hepatosplenomegaly and uterus corresponding to 29 weeks gestation. An emergency caesarean section confirmed widespread metastases to the ovaries, mesentery and placenta. A viable male foetus was delivered with features of intrauterine growth restriction. The baby survived, but the mother died a week later. This case highlights the importance of thoroughly assessing placentas and babies of patients with melanoma for metastases.
