Could it still be malignant melanoma or just a poorly differentiated neoplasm?

How Just Could a Robot War Be?

While modern states may never cease to wage war against one another, they have recognized moral restrictions on how they conduct those wars. These “rules of war” serve several important functions in regulating the organization and behavior of military forces, and shape political debates, negotiations, and public perception. While the world has become somewhat accustomed to the increasing techno...

A pelvic mass in a 10-year-old: could it be a Hydatid Cyst?

This article reports a pelvic hydatid cyst in a 10-year-old boy who initially presented with right flank pain. Computed tomography (CT) revealed a cystic lesion containing internal densities, which was found to be a hydatid cyst between the bladder and rectum during surgery. The lesion was excised and sent to a pathology laboratory for further examination.

Aortic Dissection or MI? It could be both

Acute aortic dissection is a potentially lethal vascular emergency that involves the rapid development of a false blood channel within the media of the aorta. If left untreated, approximately 50% of patients die in the first 48 hours, and the mortality rate increases by 1% to 3% per hour [1,2]. Despite recent advances in diagnostic methods, misdiagnosis occurs in 25%-50% of patients on initial ...

A Poorly Differentiated Malignant Neoplasm Lacking Lung Markers Harbors an EML4-ALK Rearrangement and Responds to Crizotinib

Suspected metastatic site lesions that are poorly differentiated present a diagnostic challenge when morphologic and immunohistochemical profiling cannot establish the primary tumor site. Here we present a patient diagnosed with both a malignant neoplasm in the lung and a right upper extremity (RUE) neoplasm of unclear histogenetic origin. Immunohistochemical staining performed on the latter sp...
