Metastatic Clear Cell Carcinoma of Unknown Primary Origin in an Elderly Female Patient With Paraneoplastic Hypercalcemia.

Metastatic clear cell carcinoma (mCCC) is a rare histological subtype of cancer with ovarian and renal origins most common primary sites. Cancer of unknown primary origin (CUP) is a rare type of cancer in the United States and the most common histologic subtypes are adenocarcinoma, squamous cell cancer, and neuroendocrine cancer. We are presenting a rare case of an 86-year-old female patient with mCCC of unknown origin, biopsy and staining showed renal and ovarian in the differential of primary cancer type.

Inhibitors in Colorectal Cancer: A Systematic Review.

Colorectal cancer (CRC) is the second-leading cause of cancer-related deaths globally. mutation is present in about 10% of CRC patients and is associated with a poor response to chemotherapy. These patients have a relatively poor prognosis.

Triple Lymphoma and Transformation to Diffuse Large B-Cell Lymphoma Finding at the Time of Diagnosis.

In this report, we present the case of a patient with an uncommon triple diagnosis of (1) follicular (nodular) lymphoma, (2) nodular lymphocyte predominant Hodgkin lymphoma, and (3) diffuse large B-cell lymphoma non-germinal center B-cell (non-GCB) subtype. Although transformation of follicular lymphoma and nodular lymphocyte predominant lymphoma to more aggressive forms such as diffuse large B-cell lymphoma is possible; it generally happens many years after diagnosis. Moreover, there have been reported cases of follicular lymphoma with transformation and nodular lymphocyte predominant Hodgkin lymphoma with transformation at the time of diagnosis, but it is very uncommon to see all three present on initial diagnosis.

Hairy Cell Leukemia: Hepatic Affinity Status Post Splenectomy.

Hairy cell leukemia (HCL) is a rare neoplasm of the B-cell lineage that is characterized by an indolent course and infiltration of the spleen, the bone marrow, and the reticuloendothelial system. Splenectomy is considered an effective treatment for peripheral cytopenia in patients with HCL. Hepatic involvement of hairy cells with infiltration of the sinusoidal endothelial cells is rarely reported in the literature and is not well understood.

Efficacy and tolerability of isocitrate dehydrogenase inhibitors in patients with acute myeloid leukemia: A systematic review of clinical trials.

Background: Acute myeloid leukemia (AML) is a hematological malignancy due to anomalous differentiation and proliferation of hematopoietic stem cells with myeloid blast buildup. Induction chemotherapy is considered the first line of treatment in most patients with AML. However, targeted therapy in the form of FLT-3, IDH, BCL-2, and immune checkpoint inhibitors, can be considered as the first line depending on their molecular profile, resistance to chemotherapy, comorbidities, etc.
