Endometriosis of the Pancreas Presenting as a Cystic Pancreatic Neoplasm with Possible Metastasis

Southern Medical Journal, 2004
The authors report a case of endometriosis that presented as a cystic mass in the tail of the pancreas, leading to extensive evaluation and ultimately a major surgical resection. The diagnosis was made by histopathological evaluation, revealing endometrial glands and stroma in the wall of the mass with hemorrhagic fluid in the cystic lumen, compatible ...

Metastasis of Invertebrate Neoplasms

1989
The ability to demonstrate metastasis in an invertebrate is a difficult problem for several reasons: (1) many invertebrates have no circulatory system (2) the majority of invertebrates that do have a circulatory system is based on an open system with large blood sinuses (3) many invertebrates have non discrete organ systems (4) relatively few neoplasms

[The treatment options of pancreatic neuroendocrine neoplasm with liver metastasis].

Zhonghua wai ke za zhi [Chinese journal of surgery], 2017
Liver metastasis is the one of the main prognostic factors of pancreatic neuroendocrine neoplasm (PNEN). With the development of multidisciplinary collaboration among surgical oncology, medical oncology, and intervention treatment, the treatment of PNEN with liver metastasis gradually tends to become diversification.

Skin Metastasis From Malignant Neoplasms-Reply

Archives of Dermatology, 1983
In Reply.— Dr Hussey correctly points out that the vertebral venous system described by Batson 1,2 is an important route of spread of metastases. Its presence may well explain the predilection for metastases from carcinoma of the breast, prostate, and rectum, as well as other pelvic malignant neoplasms, for the axial skeleton.

Expression of a potential metastasis suppressor gene (nm23) in thyroid neoplasms

World Journal of Surgery, 1993
AbstractIdentification of multiple clinical and pathologic prognostic factors in differentiated thyroid cancer has permitted some degree of risk stratification. However, these clinical indices fail to distinguish potential intrinsic differences in tumor virulence.

[Study on the early liver metastasis forecast of colorectal neoplasms].

Zhonghua wai ke za zhi [Chinese journal of surgery], 2006
To obtain some effective objective markers used to predict the early liver metastasis of colorectal tumor, the relationship of liver metastasis of colorectal tumor with associate detection three markers such as CK20mRNA, CD44v6 and VEGF was studied.The expression of CK20mRNA in patrol venous blood from 30 colorectal cancer patients was detected by ...

Perivascular epithelioid cell neoplasm of the bladder with peritoneal metastasis

Canadian Journal of Urology
Perivascular epithelioid cell tumors (PEComas) are a diverse group of mesenchymal neoplasms. While they have been described throughout the genitourinary system, PEComas are quite rare within the bladder. We present the case of a 37-year-old male who presented in clot retention and was found to have a bladder PEComa.

Pathways for cervical metastasis in malignant neoplasms of the head and neck region

Clinical Anatomy, 2011
AbstractThere have been significant changes in the evaluation and management of lymphatic metastases in the neck during the past several decades, and knowledge of the functional anatomy of the cervical lymphatics is fundamental to the clinical management of metastasis in this region.

Leptomeningeal Metastasis of Primary Central Nervous System (CNS) Neoplasms

2005
Leptomeningeal dissemination of primary CNS tumors varies widely by histologic subtype. In certain tumors including medulloblastoma, ependymoma, germ cell tumors, and primary CNS lymphoma, seeding of the cerebrospinal fluid space is a critical factor in determining stage, prognosis and appropriate therapy.

Neoplasms Metastasis Deriving from Supporting Tissues

1989
The supporting tissues of man are composed of five types, each having its own main malignant neoplasm: adipose tissue (liposarcoma), chordal tissue (malignant chordoma), chondroid tissue (malignant fibroma), cartilage (chondrosarcoma), and bone (osteosarcoma). The supporting tissues of the organisms have been reviewed by Kaiser (1981, pp.
