Congenital mesoblastic nephroma (CMN) are low grade spindle cell neoplasms with myofibroblastic differentiation and classified morphologically as classic, cellular, or mixed. Recurrent genetic alterations have been identified – EGFR internal tandem duplication is associated classic morphology, ETV6::NTRK3 fusion the cellular subtype. We report a case of variant CMN rarely described KIAA1549::BR...

In T cell malignancy, rearrangements of chromosome 14 have been observed with a break in the band that contains the alpha chain gene for the T cell receptor (TCR). Because the beta chain TCR gene is in chromosome band 7q34, we searched for and report finding specific rearrangements of 7q34 exclusively in T cell malignancies. The rearrangements were reciprocal translocations between 7q34 and oth...

We report herein a very rare case of acute lymphoblastic leukemia having a chromosomal constitution of 48,XY,+X,+5,t(9;22)(q34;q11) in the bone marrow. A patient with additional chromosomes X and 5 with a Philadelphia chromosome has not been reported previously. However, no abnormal karyotype was obtained from the lymphocytes in our patient, and he did not have the characteristics of Klinefelte...

Alterations of 3p are the most frequently observed changes in follicular thyroid carcinomas. Loss of 3p25-pter has been speculated to be a critical event in the malignant transformation of a subset of thyroid follicular neoplasms. The present report describes a minimally invasive follicular thyroid carcinoma (FTC) with a balanced t(3;7)(p25;q34) and dic(15;22)(p11;p11) as the only abnormalities...

Chronic myeloid leukemia (CML) is a stem cell disorder characterized by unrestricted proliferation of the myeloid series that occurs due to the BCR-ABL fusion oncogene as a result of reciprocal translocation t(9;22) (q34;q11). This discovery has made this particular domain a target for future efforts to cure CML. Imatinib revolutionized the treatment options for CML and gave encouraging results...

Ehlers-Danlos syndrome has been divided into several different types according to the variety and severity of clinical manifestations, and may follow autosomal dominant, autosomal recessive, or X linked patterns of inheritance. Only rarely have chromosome anomalies been seen in patients manifesting phenotypic features of the syndrome and most are considered insignificant. However, one case repo...
