Tumor sincrónico de endometrio y ovario. Patología infrecuente en ginecología oncológica

Endometrial cancer remains the most common gynecological tumor in women in the United States of America. The simultaneous finding of endometrial and ovarian neoplasm, as a synchronous tumor, accounts for about 5 - 10 % of endometrial and ovarian tumors. Therefore, is a rare entity. Consideration as restricted metastases or pseudometastasis to define the spread of this kind of tumor, is becoming more relevant nowadays thanks to the latest advances in the field of immunohistochemistry and molecular biology. In this article we present the case of a 57-year-old patient initially diagnosed with FIGO stage IIIA endometrial carcinoma; subsequently, it was a synchronous endometrial tumor stage IB and IC ovary, despite the presurgical suspicion of a metastatic tumor. Keywords: Endometrial Neoplasm, Ovarian Neoplasm, Synchronous Neoplasm, Multiple Primary Neoplasm, Neoplasm Metastasis.

Synchronous Interdigitating Dendritic Cell Sarcoma and B-Cell Small Lymphocytic Lymphoma in a Lymph Node

A gradually enlarging axillary mass in a 79-year-old man was excised. The specimen was processed for light microscopy, immunohistochemical studies, and electron microscopy; gene rearrangement studies were also performed. A diagnosis of an interdigitating dendritic cell tumor of the lymph node and a B-cell small lymphocytic lymphoma occurring in the same anatomic location was made. We found that although rare cases of interdigitating dendritic cell tumor with an associated secondary malignancy have been described in the literature, to our knowledge, this is the first report of interdigitating dendritic cell tumor and synchronous neoplasm diagnosed at the same site. A possible relationship between the 2 disorders is also discussed.
