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.

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.
