Uterine heterologous malignant mixed Müllerian tumor in a dwarf rabbit (Oryctolagus cuniculus)

Primary peritoneal malignant mixed mesodermal (Müllerian) tumor.

AIMS AND BACKGROUND Malignant mixed mesodermal tumor (MMMT) is a biphasic neoplasm (carcinosarcoma) composed of both epithelial and mesenchymal elements. Extragenital MMMT, including primary peritoneal MMMT, is an extremely rare tumor with features consistent with its origin from the secondary Müllerian system. The neoplastic elements of extragenital MMMT presumably arise directly from the meso...

Herpes simplex encephalitis in a domestic rabbit (Oryctolagus cuniculus).

An adult domestic rabbit showing neurological signs was subjected to euthanasia. At necropsy, macroscopical lesions were absent. Histopathologically, extensive lesions were seen, particularly in the cerebral cortex. Non-suppurative meningitis was present and there was lymphocytic and plasmacytic perivascular cuffing in the neuropil. The cerebral cortex showed extensive segmental neuronal and gl...

THE ORGANISATION OF RABBIT CONTROL (Oryctolagus cuniculus) IN WESTERN AUSTRALIA

Under Western Australian legislation, landholders have an obligation to control rabbits on their properties; local authorities the responsibility to supervise their work whilst the Agriculture Protection Board has a Statewide supervisory and co-ordination role. Prior to 1950 (when the Agriculture Protection Board was formed) the central role was in the hands of a Government department which, th...

Malignant Müllerian Mixed Tumor of the Uterine Cervix with a Small Cell Neuroendocrine Carcinoma Component

Malignant Müllerian mixed tumors (MMMTs) of the uterine cervix are extremely rare, accounting for 0.005% of all cervical malignancies. To date, only approximately 50 well-documented cases have been reported. Although several epithelial components have been described in cervical MMMTs, small cell neuroendocrine carcinoma (SCC) has not appeared in the English literature. We present a 43-year-old ...
