Popliteal Lymph Nodes

Primary vascular neoplasms of lymph nodes are rare, and appear not to have previously been reported in domestic animals. This report describes hemangiomas and a lymphangioma in lymph nodes of aged Beagle dogs. Eight hemangiomas (4.8%) and one lymphangioma were present in 165 examined popliteal lymph nodes, and one hemangioma occurred in a hepatic lymph node. The hemangiomas were cavernous and benign.

Tissues from 13 experimentally inoculated mule deer (Odocoileus hemionus) from Oregon, studied by G. Hudkins and T. P. Kistner in 1976 and L. D. Koller, T. P. Kistner, and G. Hudkins in 1977, were reexamined. The following additional information on Sarcocystis hemionilatrantis was obtained. Two types of meronts were found in deer necropsied between 29 and 41 days postinoculation (DPI). Type 1 meronts were in capillaries in adrenal glands, kidney, lymph node, lung, choroid plexi, and spleen; meronts were 20.5 × 13.5 μm (14−32 × 10−20 μm; n = 26) and contained 20 to 35 nuclei. Type 2 meronts were found in macrophages in muscular tissues; these meronts were 20 × 14 μm (10−35 × 7−19 μm; n = 7) and contained 10 to 60 merozoites. Sarcocysts were seen in three deer at 63, 65, and 90 DPI. At 63 and 65 DPI sarcocysts were immature and their walls were thin (< 1 μm) and smooth. At 90 DPI, sarcocysts were up to 525 μm long and 50 μm wide; the sarcocyst wall was 1 to 2 μm thick and cross striated. In the same deer another type of mature sarcocyst was also seen; sarcocysts were up to 825 μm long, the walls were 2 to 4 μm thick and lacked cross striations. Two additional 3-day-old deer were inoculated orally with sporocysts from the feces of a dog fed meat from a mule deer from Montana naturally infected with Sarcocystis sp. Deer No. 1, fed 107 sporocysts, was killed at 14 DPI and deer No. 2, fed 5 × 106 sporocysts, was killed at 24 DPI. At 14 DPI, meronts were found in capillaries and arteries in the lung, heart, and spleen; the meronts were 26.5 × 20 μm (14−39 × 14−25 μm; n = 31) and contained up to 100 nuclei. At 24 DPI, intravascular meronts were found in the spinal cord, hepatic lymph node, kidney, thyroid gland, and mesenteric lymph node. In addition, meronts were found in macrophages in muscular tissues; these meronts were 16 × 10 μm (10−28 × 7−14 μm; n = 10) and contained up to 40 nuclei.

Hepatic Lymph Node

Abstract The frequency and significance of hepatic lymph node (HLN) metastasis were retrospectively evaluated in 43 patients with unresectable synchronous liver metastasis of colorectal cancer who underwent resection of the primary tumor and histopathologic evaluation of HLNs between March 1997 and August 2007. HLN metastasis was detected in 12 patients (27.9%). No significant correlations were observed between the presence of HLN metastasis and any of the 12 clinicopathologic factors examined. On multivariate analysis using the Cox proportional hazards model, the presence of HLN metastasis (P  =  0.002), along with a large number (≥4) of regional lymph node metastases (P  =  0.003), and nonuse of oxaliplatin-based chemotherapy (P  =  0.005) were identified as independent risk factors for shorter survival. To establish a new therapeutic strategy for initially unresectable liver metastasis of colorectal cancer, HLNs should be examined histologically in patients undergoing resection of hepatic lesions when they are rendered resectable by effective chemotherapy.
