  • 18세령 중성화 암컷 요크셔테리어종 개가 우측 4번 및 5번 유선 부위에 위치한 대형 복부 종괴로 내원하였다. 외과적으로 적출한 유선 종괴가 병리학적 진단을 위하여 의뢰되었다. 병리조직학적 소견으로 종괴는 표피에서 피하조직에 걸쳐 다발성 및 융합된 종양성 집락들로 구성되어 있었다. 종양성 집락들은 면포상, 고형상, 사상 및 미세유두상 등의 매우 다양한 형태를 나타내었으며, 큰 종양성 유선 도관은 주변조직으로의 강한 침습성을 나타내고 있었다. 진피표층에 위치한 다수의 림프관 얼기들과 진피의 림프관에는 무수히 많은 종양세포의 색전을 가지고 있었다. 종양을 구성하고 있는 세포들의 약 50%이상이 면포상의 형태를 띠고 있기 때문에, 본 증례는 최근의 개 유선 종양의 분류에 근거하여 개의 유선에서 발생한 유선 면포 암종으로 진단하였다.

  • A 15-year-old intact Yorkshire terrier was presented with anorexia, lethargy, and a pale mucous membrane. A physical examination one year ago revealed right testis mass and subcutaneous petechia. Blood work revealed severe thrombocytopenia and mild anemia, and no abnormalities were found in serum chemistry or ultrasonography. The preoperative serum estrogen concentration was moderately elevated. The enlarged testis was surgically removed. A well-encapsulated mass composed of polyhedral or round with abundant eosinophilic cytoplasm containing fine granular or vacuolation were found in a histological examination of the removed tissue. The nuclei of tumor cells were round, and mitotic figures were low but neoplastic cells showed a mild invasive tendency to adjacent tissues with contained neoplastic cell emboli in one lymphatic lumen. A diagnosis of a malignant Leydig cell tumor was made. The patient recovered from surgery uneventfully, but his condition worsened despite repeated transfusions and supportive therapy, and he was euthanized according to the owner's decision. Leydig cell tumor should be included in estrogen toxicity associated with testicular mass.

  • A ten-year-old dog was presented with pancreatitis and increased hepatic enzymes. On necropsy a large firm mass was observed in the liver extending to the gall bladder. Smaller masses with similar texture were found in multiple organs including lung, stomach, pancreas, lymph nodes, omentum, and mesentery. Neoplastic cells were spindle shaped with prominent osteoid production and occasional trabeculae of woven bone. Tumor cell emboli were observed in the blood vessels and lymphatics of the omentum and stomach. Hepatic osteosarcoma with systemic metastasis is very rare and may serve to broaden the diagnostic spectrum of hepatic and pancreatic diseases in dogs.
