The patient was an 84-year-old man who presented with a palpable, left breast mass. Following ultrasound, mammography, and ultrasound-guided core needle biopsy, the lesion was diagnosed as papillary carcinoma. Findings included a complex, cystic mass on ultrasound; a well-circumscribed, high-density lesion on mammogram; and a lack of highlighting of myoepithelial cells within fibrovascular cores on immunostaining.

Small cell neuroendocrine carcinoma (NEC) of the cervix is a rare gynecological malignancy, constituting 2%-5% of all such cases. As high-risk Human Papilloma Virus (HR-HPV) infections contribute to 85% of these tumors, small cell NEC poses a significant risk for solid organ transplant recipients, increasing their risk of progressive disease. We present a case of an uterine cervix small cell NEC with metastasis to the bladder and pleural cavities in a 53-year-old woman with a past medical history of kidney transplantation, who presented with abnormal uterine bleeding.

Truncation mutations in cardiac myosin binding protein C (cMyBP-C) are common causes of hypertrophic cardiomyopathy (HCM). Heterozygous carriers present with classical HCM, while homozygous carriers present with early onset HCM that rapidly progress to heart failure. We used CRISPR-Cas9 to introduce heterozygous (cMyBP-C+/-) and homozygous (cMyBP-C-/-) frame-shift mutations into MYBPC3 in human iPSCs.
