Masquerading as Pneumonia: A Lung Neuroendocrine Tumor Case Report.

The presentation of recurrent pneumonia, particularly in the same lobe, should raise suspicion for possible neuroendocrine tumors of the lung within that respective lobe. Commonly, these types of tumors will have a gastrointestinal origin with a larger incidence of carcinoid syndrome, but they may also originate in the pancreas or lungs. This case illustrates the potential for a masked lung tumor in an otherwise young and healthy 31-year-old patient, with a short history of tobacco dependence and unremarkable family history, who presents with recurrent pneumonia and dyspnea. Although rare in itself, this case was even more unique due to the partial calcification of the neuroendocrine tumor mass along with causing a collapse in the entire right middle lobe.

An Unusual Case of Bleeding: Acquired Hemophilia A.

Acquired hemophilia A (AHA) is a bleeding disorder, autoimmune in nature, in which the body produces IgG antibody inhibitors that attack coagulation factor VIII, causing deficiency. It is largely seen in the elderly, but most cases are idiopathic. Cases of acquired hemophilia A can occur in the presence of neutrophilia, infection, acute physiological stress, medication effect, tissue necrosis, various inflammatory disorders, and/or malignancy, which presents a formidable challenge with clinical workup. This case illustrates the potential for a masked bleeding disorder in a complex elderly male patient and the value of a thorough history-taking and workup. Although rare, acquired hemophilia recognition is essential for appropriate therapies to be started as early as possible and for cases to not easily be confused for another bleeding disorder in an acute care setting after ruling out other acute/common causes of similarly presenting symptoms.
