It is well known that in advanced cervical metastatic disease of head and neck squamous cell carcinoma, the incidence of distant metastasis is high. A case of distant metastasis to the scapular muscles from an uncontrolled cervical metastasis of laryngeal carcinoma is presented. Other unusual metastatic sites are reviewed and the possible mechanism of the spread is discussed.

Aneurysmal bone cysts (ABCs) are rare benign osteolytic tumors which occur most frequently within the first two decades of life and can lead to pathological fractures. They have characteristic imaging and histologic features and have historically been classified into two types: primary ABCs, which are true neoplasms linked to specific oncogenes, and secondary ABCs, which are preceded by other bone lesions. The occurrence of multiple concurrent primary ABCs is exceedingly rare; with only a few cases reported in the published literature.

Vitamin B12 deficiency is a potentially severe condition with clinical manifestations ranging from nonspecific symptoms, such as asthenia and glossitis, to severe hematological problems, including pancytopenia and megaloblastic anemia. One of the rare phenomena associated with this condition is pseudo-thrombotic microangiopathy (pseudo-TMA), which can mimic diseases such as thrombotic thrombocytopenic purpura (TTP), leading to possible misdiagnosis and inappropriate treatment. In this article, we present the case of a 62-year-old man with a history of intravenous drug use, untreated hepatitis C, smoking, and alcoholism.

Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), is currently used in the therapy of several solid malignancies. This agent has been associated with several dermatological side-effects, the most common being papulo-pustular acneiform rash. Herein we describe a unique skin effect in a patient treated with erlotinib for non-small cell lung cancer.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL) in adults, constituting a significant portion of global incidence rates. DLBCL can be further classified via genetic expression profiling into molecular subsets consisting of not-otherwise specified (NOS) subset being the most prevalent, germinal center B-cell-like (GCB) subset, and activated B-cell-like (ABC) subset. The ABC subset, marked by abnormal NF-κB signaling, is associated with poorer outcomes.

Introduction And Importance: Paragangliomas are rare neuroendocrine tumors, typically arising from extra-adrenal chromaffin cells. Primary intra-spinal paragangliomas are uncommon, and metastatic spinal paragangliomas without paraneoplastic symptoms are even rarer. This case highlights the diagnostic challenges posed by such rare tumors.
