Paraneoplastic Neurologic Syndromes (PNS) are remote effects of malignancy involving the nervous system not related to tumor invasion, compression, or metastasis. These syndromes are rare, with approximately 1% of adults with cancer having an associated PNS. They are immunologic in origin where malignancy triggers production of autoantibodies against various antigens of the nervous system, as antigens located on the tumor mimic those of the nervous system.

In this abstract, we will be presenting a case of a unique pathological finding in a patient diagnosed with a solitary pulmonary nodule.

Among transplant recipients, atypical bacterial infections are not uncommon. Tuberculosis (TB) can have unusual manifestations, especially in immunocompromised hosts. Diagnosis of TB should be considered if a patient born in TB-endemic area presents with unusual symptoms.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) syndrome is a rare congenital anomaly, occurring in 1 in 300,000 live births. This condition will commonly lead to ischemia and heart failure and without intervention, results in a 90% mortality rate within the first year of life.

Pulmonary vein thrombosis (PVT) is a rare and fatal condition if not recognized early that often presents with nonspecific symptoms such as cough, dyspnea, or hemoptysis. Etiological mechanisms include vascular torsion or direct injury (major trauma, post-surgical).

Lung carcinoma has become a leading cause of death in the USA, which has led to an increase in differentiation including multiple sub-types.  Pulmonary Sarcomatoid carcinoma (PSC) is one sub-type that is characterized as a poorly differentiated non-small cell carcinoma (NSCC) containing both sarcoma and sarcoma-like components with spindle or giant cell features therefore It is difficult to distinguish PSC from true sarcomas.
