Cytology, immunohistochemistry and 3-dimensional reconstruction of adenoma malignum: a case report

Acta Cytologica
Yoshiki OhtaMotohiro Kojima


Cytologic diagnosis of adenoma malignum is not easy. A case of adenoma malignum was diagnosed cytologically. A 45-year-old woman was suspected of having adenoma malignum. Her chief complaint was a mucoid cervical discharge. Transvaginal ultrasound examination showed multiple cervical cysts, and peculiar clusters of cervical columnar cells showing a channellike structure were observed cytologically. Cytologic analysis detected tumor cells with increased euchromatin and stretched nuclear membranes with distinct eosinophilic nucleoli. Intranuclear cytoplasmic inclusion bodies and lobate or budlike nuclei were also observed. Immunohistochemically, both HIK-1083 and carcinoembryonic antigen (CEA) were positive in the histologic specimens, although only a few glands were positive for CEA. On 3-dimensional reconstruction of normal cervical tissue, glands showing similar calibers and straight lines also had a "weeping willow-shaped" growing pattern. In the adenoma malignum there were large and small glands showing a cumuliform pattern, and cystic dilation with discontinuity and fusion of glands could be seen. The nuclear findings mentioned above were thought to be diagnostic characteristics of adenoma malignum. Three-dimensional recons...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
