CASE 041

This month we discuss the relevance of ultra-sensitive molecular techniques, such as NGS and ddPCR that help detect rare variants in disease as illustrated in this exceptional presentation of a treatment-naïve adenocarcinoma patient with co-occurrence of denovo EGFR T790M mutation and EGFR del19 mutation, wherein Osimertinib, a third generation TKI, may offer the best chance for clinical response.

CASE 042

This month we discuss a case of Chronic Myeloid Leukemia (CML) with a rare co-expression of p210 and p230 encoding BCR-ABL1 fusion transcripts. This case highlights the diagnostic coverage and value of molecular profiling for a heterogeneous disease such as CML.

CASE 043

This month we discuss a case of an extra-renal rhabdoid tumor, a rare SMARCB1/SMARCA4 deficient mesenchymal neoplasm. In view of its rarity, aggressive course, and a polyphenotypic immunoprofile that poses diagnostic challenges, this case highlights the salient features of an extra-renal rhabdoid tumor, the importance of INI-1 evaluation and exclusion of its mimics.

CASE 044

This month, we discuss a case of Myxoinflammatory fibroblastic sarcoma in a seven month old infant's eyeball. In view of its rarity in children, especially in an infant (possibly the youngest patient ever reported in literature) with a nonspecific immunoprofile that poses as a diagnostic challenge. This case highlights the salient features of myxoinflammatory fibroblastic sarcoma and exclusion of its mimics.

CASE 045

This month we discuss a rare case of "48,XXYY Genotype (Variant Klinefelter Syndrome): A case report of a rare Chromosomal anomaly that cause infertility, developmental and behavioral disorders".

CASE 046

This month we discuss a rare case of chronic myeloid leukemia in blast crisis carrying a novel karyotype and the rare BCR-ABL1 variant e13a3(b2a3). This case highlights the need for a multi-technique approach to avoid false negatives and misdiagnosis.

CASE 047

This month we discuss a rare case of a 15 year old girl who was clinically diagnosed as Turner syndrome with short stature and pubertal delay: Karyotype with 46,X,psu idic(X)(p22.3) (Variant Turner Syndrome/delXp).

CASE 048

This month we discuss a rare case of tumor which can mislead the clinicians. This case had an extensive squamous differentiation, which has been described in only one case until now.

CASE 049

CASE 051

This month we are going to discuss the efficacy of Next Generation Sequencing (NGS) technology to detect a novel pathogenic variant in the BRCA1 and BRCA2 genes. Identifying a pathogenic mutation in the BRCA1/2 gene confirms the diagnosis of hereditary breast and ovarian cancer (HBOC) in a patient, which makes the patient a potential candidate for targeted therapy. Since, in patients with BRCA1/2 germline pathogenic mutations, Olaparib, a PARP inhibitor, has been approved by FDA for advanced ovarian cancer, who have been treated with three or more prior lines of chemotherapy, HER2-negative metastatic breast cancer, who have been treated with chemotherapy and triple-negative breast cancer (TNBC) patients.
