Atypical MYC rearrangement pattern of 3? deletion and 5? amplification along with independent IGH rearrangement: A case study

A spectrum of Cellular homolog of the v-myc oncogene (cMYC) alterations such as translocation, overexpression, mutation, and amplification plays an important role in lymphomagenesis, particularly in high-grade lymphomas, and are associated with prognostic significance. Accurate identification of cMYC gene alteration is important for diagnostic, prognostic, and therapeutic implications. With the application of different FISH (fluorescence in situ hybridization) probes that helped overcome the analytical diagnostic challenges as a result of variant patterns, we report rare, concomitant, and independent gene alterations in cMYC and Immunoglobulin heavy-chain gene (IGH) with detailed characterization of its variant rearrangement. Short-term follow-up post R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) therapy seemed to be favorable. Accumulation of many more literature studies on such cases with their therapeutic implications would lead to the categorization of these cases as a separate subclass in large B-cell lymphomas followed by molecular targeted therapy.

Wolf–Hirschhorn syndrome: A case demonstrated by a cytogenetic study.

We present a case with a 4p terminal deletion, evidenced in GTG-banded chromosome study. Phenotypic signs described in the classical Wolf–Hirschhorn syndrome were found on clinical examination of our patient.
