BACKGROUND: The distinction of trichoepithelioma from basal cell carcinoma in small superficial biopsies is important but often challenging. This has inspired many scientists to test the validity of immunohistochemical markers in the differential diagnosis. OBJECTIVES: to develop an immunohistochemical protocol that helps in differentiation between both TE and BCC with higher sensitivity and specificity. METHODS: Using standard immunohistochemical techniques, we examined 10 TEs and 19 BCCs for the expression of CK19, Ki67, Androgen receptors (AR), CD10, and PHLDA1...

Patient-derived tumor xenograft models represent a promising preclinical cancer model that better replicates disease, compared with traditional cell culture; however, their use is low-throughput and costly. To overcome this limitation, patient-derived tumor organoids (PDOs) were established from human lung, ovarian and uterine tumor tissues, among others, to accurately and efficiently recapitulate the tissue architecture and function. PDOs were able to be cultured for >6 months, and formed cell clusters with similar morphologies to their source tumors...

Loudness dependence of auditory evoked potentials (LDAEP) is a widely used electroencephalography (EEG) based biomarker for central serotonergic activity. Serotonin has been shown to be associated with different psychiatric disorders such as depression and schizophrenia. Despite its clinical significance, the underlying neurochemical mechanism of this promising marker is not fully understood and further research is needed to improve its validity. Other neurotransmitters might have a significant impact on this measure...

We report an unusual case of uterine corpus metastasis from rectal adenocarcinoma detected using F-FDG PET/CT. A 47-year-old woman was diagnosed with rectal adenocarcinoma and treated with surgery and radiochemotherapy 3 years ago. During follow-up, she presented with lower abdomen pain and elevated tumor markers, but ultrasonography findings were unremarkable. We performed an F-FDG PET/CT scan, which showed intense F-FDG avidity in the myometrium of the uterine corpus. Uterine corpus metastasis was suspected, and complementary MRI and diagnostic curettage histopathology confirmed uterine metastasis from rectal adenocarcinoma...
