The following case potentially provides insight into the mechanisms of lymphogenic metastasis in sinonasal cancer. A 63-year-old patient who presented with progressive diplopia and left-sided periocular pain was diagnosed with a cT4bN0M0 mucosal melanoma of the ethmoid sinus. She underwent a combined endonasal and transcranial tumor resection, and an orbital exenteration.

The subareolar Sappey's plexus was studied using color lymphography and immunohistochemical methods with a panel of antibodies to podoplanin, smooth muscle actin, low molecular weight cytokeratin AE1/AE3, and GATA3 on archival material obtained during radical mastectomies and sectoral resections with lymph node dissection from 86 patients diagnosed with non-special type breast cancer. At the macro- and microscopic levels, the connection between the subareolar lymphatic plexus and the lymphatic system of the breast parenchyma has been demonstrated. In triple negative breast cancer with metastases to the axillary lymph nodes, the involvement of subareolar lymphatic plexus into lymphogenous metastasis to the lymph nodes of the axillary lymphatic collector was shown.

Currently, all pheochromocytoma/paraganglioma (PPGLs) are considered malignant due to metastatic potential. Consequently, PPGLs are divided into «metastatic» and «non-metastatic». Metastatic PPGLs can be with synchronous metastasis (metastases appear simultaneously with the identified primary tumor) or metachronous (metastases develop after removal of the primary tumor).

Background: Colorectal cancer (CRC) often metastasizes to the liver, lungs, lymph nodes, and peritoneum but rarely to the bladder, small intestine, and skin. We here report the rare metastasis of anal cancer in the left bladder wall, followed by metastases to the small intestine and skin, after abdominoperineal resection and left lateral lymph node dissection with chemotherapy in a patient with clinician Stage IVa disease.
Case Presentation: A 66-year-old man presented with 1-month history of bloody stool and anal pain and diagnosed with clinical Stage IVa anal cancer with lymph node and liver metastases (cT3, N3 [#263L], M1a [H1]).
