The development of multitargeted tyrosine kinase inhibitors has provided significant advances in the treatment of renal cell carcinoma. This case describes initial therapy for managing renal cell cancer with the administration of sorafenib, a multitargeted tyrosine kinase inhibitor. We report the development of localized palmar-plantar epidermal hyperplasia, a rare but significant cutaneous adverse event from sorafenib therapy.Mild-to-moderate dermatologic toxicity from sorafenib has been well described in the literature. We also review the current knowledge and the proposed hypothesis for the development of cutaneous events related to tyrosine kinase inhibitors. This particular case represents a unique form of dermatologic toxicity to sorafenib that has not previously been described in the literature. The Oncologist

Background Hereditary colon cancer is characterized by the inheritance of an abnormal gene mutation which predisposes to malignancy. Recent advances in genomic medicine have identified mutations in “novel” genes as conferring an increased risk of colorectal cancer. Mutations in the BRIP1 gene ( BRCA1 Interacting Protein C- terminal helicase 1) are known to increase the risk of ovarian and breast cancers, but this genes association with colon cancer has not been previously reported. Case presentation We describe two patients with colon cancer whose tumor tissue were found to harbor BRIP1 mutations on analysis by next-generation sequencing. These patients were confirmed by analysis of lymphocytes to carry the mutation in the germline as well. Conclusions These case reports highlight a previously unreported association of BRIP1 germline mutations with colon cancer predisposition.

: Reirradiation can offer long-term survival for patients with recurrent, previously irradiated head/neck cancers.

Sickle-beta + (b + ) thalassemia is a double heterozygous genetic disorder characterized by both a qualitative and quantitative abnormality. We present a case of an African American male who was first diagnosed with sickle cell disease (SCD) at the age 23 years when he presented with generalized bone pain, fever, and hepatosplenomegaly. Laboratory findings included thrombocytopenia, microcytic anemia, and markedly elevated ferritin. He was subsequently diagnosed with a sickle-beta thalassemia hemoglobinopathy. Findings in the bone marrow aspirate and biopsy were consistent with hemophagocytic lymphohistiocytosis (HLH). HLH resolved with the resolution of sickle cell bone pain crisis without use of immunosuppressive therapy. To the best of our knowledge this is the first documented case of HLH associated with sickle cell bone pain crisis. Am.
