The incidence of seborrheic keratosis (SK) generally increases with age and are mostly localized on the trunk, face and neck, especially on sun-exposed areas. The association between SK and skin malignancies appears to be accidental, but transformation occurs more frequently in sun-exposed areas. Histopathological examination of all SK cases should be considered, especially when SK lesions exhibit atypical clinical manifestations, such as ulceration and cresting, as they may herald malignant transformation. In addition, other features associated with malignant transformation include excoriations or hemorrhages identified on the lesion, modification and evolution of the macroscopic characteristics, and the presence of local erythema or pruritus. Immunocompromised patients exhibit an increased risk of malignant transformation, even when radiation is involved.

The Epstein-Barr virus (EBV) infects nearly 90% of adults globally and is linked to over 200,000 annual cancer cases. Immunocompromised individuals from conditions such as primary immune disorders, HIV, or posttransplant immunosuppressive therapies are particularly vulnerable because of EBV's transformative capability. EBV remodels B cell metabolism to support energy, biosynthetic precursors, and redox equivalents necessary for transformation.

Purpose: Trophoblast cell-surface antigen 2 (Trop2) is overexpressed in various solid tumors and contributes to tumor progression, while its expression remains low in normal tissues. Trop2-targeting antibody-drug conjugate (ADC), sacituzumab govitecan-hziy (Trodelvy), has shown efficacy in targeting this antigen. Leveraging the enhanced specificity of ADCs, we conducted the first immunoPET imaging study of Trop2 expression in gastric cancer (GC) and triple-negative breast cancer (TNBC) models using Zr-labeled Trodelvy ([Zr]Zr-DFO-Trodelvy).

Background: Breast carcinoma stands out as the most widespread invasive cancer and the top contributor to cancer-related mortality in women. Nanoparticles have emerged as promising tools in cancer detection, diagnosis, and prevention. In this study, the antitumor and apoptotic capability of silver nanoparticles synthesized through Scrophularia striata extract (AgNPs-SSE) was investigated toward breast cancer cells.

There are many histologic types of gynecologic malignancies. I reviewed three rare ovarian tumor types that have poor prognoses. Ovarian mesonephric-like adenocarcinoma (MLA) is a newly described histological type known for its aggressive behavior.

Ectopic breast tissue (EBT) represents a congenital anomaly caused by incomplete regression of mammary ridges at the time of embryonic development. Typically, EBT presents along the mammary line, although usually in the axillary region, it has been located occasionally in unusual sites such as the vulva. Though relatively rare, it is generally subject to a wide range of pathologies that afflict normal breast tissue, encompassing both benign and malignant transformations.
