OBJECTIVES Placenta or placental chorangioma could be the origin site of infantile haemangioma since they share various histochemical and genetic characteristics with placental vascular tissue. The aim of the current study was to investigate the association between chorangiomas and infantile haemangiomas in singleton and multiple pregnancies. MATERIALS AND METHODS An informative questionnaire...

Chorangiocarcinoma is an extremely rare primary placental neoplasm, with only five cases reported in the literature (Table 1). Some researchers considered it as a bona fide chorangiocarcinoma, but most cases described a chorangioma with abnormal trophoblastic proliferation. In spite of atypia in cytology, marked mitosis and tumor necrosis, chorangiocarcinoma was always reported benign. No metas...

Introduction: Mirror syndrome, also referred to as Ballantyne’s syndrome, is normally defined as the development of maternal edema in association with fetal hydrops. The incidence of mirror syndrome is low and few cases have been published. We describe a case report in association with fetal Ebstein anomaly and provide a systematic review on the fetal associated conditions, maternal presentatio...

Hydrops fetalis. M. J. Becker. Department of Morbid Anatomy, Wilhelmina Gasthuis, Amsterdam. Hydrops fetalis is characterized by an abnormal accumulation of serous fluid in the tissues and body cavities, and infants who show this condition are usually either stillborn or die soon after birth. Hydrops fetalis is not a symptom of a specific disorder, but can be caused by various diseases. In a se...

AIM To investigate whether extracutaneous infantile haemangioma-like tumours are immunohistochemically similar to cutaneous infantile haemangiomas. METHODS Mammary, salivary gland, liver (one each), and placental (two cases) capillary haemangiomas and typical examples of cutaneous (eight cases) infantile haemangioma were investigated immunohistochemically for alpha smooth muscle actin and Glu...

INTRODUCTION Neoplasms of the placenta are uncommon. Tumors arising from the placental tissue include two distinct histological types: the benign vascular tumor, chorangioma, and very rarely, choriocarcinoma. Benign leiomyomas, in contrast, are very common tumors of the uterine wall and occur in 0.1% to 12.5% of all pregnant women. However, the incorporation of uterine leiomyoma into the placen...

We present two pregnancies associated with normal live births and the unusual concomitance of chorangioma and placental vascular malformation with mesenchymal hyperplasia. The enlarged placenta had the characteristic findings of chorangioma, dilated and varicose chorionic vessels and multiple vesicle-like villi containing hyaluronic acid. The vesicle-like villi showed diploid cellular DNA conte...

Since its introduction by Papanicolaou (1942), the Papanicolaou staining procedure has gained universal acceptance in cytological examinations. In routine vaginal cytological preparations the Papanicolaou stain demonstrates monilia species and a number of different organisms, and also provides excellent cytological staining of both nucleus and cytoplasm. Chorioamnionitis is one of the commonest...

Neonates at risk should be identified as early as possible to decrease neonatal morbidity and mortality (Chapter 87). The term high-risk infant designates an infant who should be under close observation by experienced physicians and nurses. Factors that define infants as being high-risk are listed in Table 91-1. Approximately 9% of all births require special or neonatal intensive care. Usually ...
