Importance: Between 5% and 10% of breast cancer cases are associated with an inherited germline pathogenic or likely pathogenic variant (GPV) in a breast cancer susceptibility gene (BCSG), which could alter local and systemic therapy recommendations. Traditional genetic testing criteria misses a proportion of these cases.

Objective: To evaluate the prevalence and clinicopathological associations of GPVs in 2 groups of BCSGs among an ethnically diverse cohort of women with newly diagnosed breast cancer.

It was hypothesized that variants in underexplored homologous recombination repair (HR) genes could explain unsolved multiple-case breast cancer (BC) families. We investigated HR deficiency (HRD)-associated mutational signatures and second hits in tumor DNA from familial BC cases. No candidates genes were associated with HRD in 38 probands previously tested negative with gene panels.

The timely diagnosis of necrotic fasciitis (NF) - an extremely rare fatal complication of acute appendicitis is difficult due to the variability of the clinical picture and depends on the degree of inflammatory changes in the appendix wall, localization, age, reactivity, and the presence or absence of comorbidities. It is characterized by high mortality rate, associated with the rapid progression of the disease with the development of septic shock and multiple organ failure. A clinical case of necrotic fasciitis of the right lower limb without damage of the anterior abdominal wall, secondary to the perforated process, as an extremely rare complication of appendicitis is presented.
