A 9
year-old, male, Rottweiler was presented with the complaint of
abnormal growth inright thoracal mammary lobe. Clinically, thoracic papilla mamma was about 5×3 cm in
size, and ostium papillare was ulcerative and infected. Radiography of the thorax
revealed findings indicative of metastasis. Ultrasonographical
examination revealed that mammary tissue had heterogeneous appearance and was surrounded
by hyperechoic areas. The mastectomy of the mammary lobe was performed under
general anesthesia. Histopathological examination revealed solid and papillary proliferations
of glandular epithelia and a high mitotic activity. A diagnosis of anaplastic mammary
carcinoma was made based on these findings. Anaplastic mammary gland carcinomas
are rarely encountered in male dogs and one incident is reported in this case
presentation.

Malignant Fibrous Histiocytic Sarcoma in a Budgerigar

| (This foto excerpted from web because there were not orginal foto) |
Radiographic examination showed that there were two separate masses of
approximately 0.5 cm (round) and 1 cm (ovoid) diameter, with well-defined
borders and diffuse opacity.
The masses were removed surgically and examined cytologically
and histopathologically. They had soft consistency; cut surfaces were
grey-whitish colored with clearly defined borders. At histopathological examination, tumor cells were large and had moderate to abundant
eosinophilic cytoplasm, round to irregular nuclei with vesicular chromatin, and
one to several distinct nucleoli. Some cells had prominent nuclear grooves.
Mitoses were uncommon.
Clinical, macroscopic, microscopic, and radiological
findings were compatible with malignant fibrous histiocytic sarcoma.
