Squamous cell carcinoma of the uterine cervix is considered the most common histologic variant of cervical cancer, with well-established treatment protocols and prognosis. An infrequent histologic variant of cervical squamous cell carcinoma is the acantholytic variant (ASCC), which is characterized by discohesive cells that result in a pseudoglandular and/or angiomatoid pattern of growth. This variant of squamous cell carcinoma has been regarded as having a poor prognosis at certain anatomic sites such as the head and neck and vulva. In the uterine cervix, the importance of this variant has not been yet established. A ten-year retrospective review of squamous cell carcinoma of the uterine cervix was performed to identify this variant and correlate it with clinical characteristics to better define its prognostic implications. During the study period 19 cases were identified containing from 10 to 80% acantholytic component. Mean age at diagnosis was 49 years. Clinical stages were 1A2 (1 case), Ib1 (16), and IIA1 (2). Median follow-up was 92 months. When compared with controls, ASCC were larger in size (1.4 vs 3.5 cm), had deeper involvement of the cervical stroma (21 vs 47%), had more lymph node metastasis (8 vs 26%), more frequent recurrences (4 vs 15%) and a shorter disease-free survival; however, no statistical differences were identified in overall survival. ASCC is an infrequent variant of cervical cancer which seems to have an impact on disease-free survival but no in overall survival.

Fluorescent biosensors offer a powerful tool for tracking and quantifying protein activity in living systems with high temporospatial resolution. However, the expression of genetically encoded fluorescent proteins can interfere with endogenous signaling pathways, potentially leading to developmental and physiological abnormalities. The EKAREV-NLS mouse model, which carries a FRET-based biosensor for monitoring extracellular signal-regulated kinase (ERK) activity, has been widely utilized both in vivo and in vitro across various cell types and organs.

Background: Immunosuppression might increase the risk of skin cancer in organ transplant recipients (OTRs), with azathioprine (AZA), exerting a fundamental role in the carcinogenesis of those tumors. This systematic review and meta-analysis aims to address the risk of developing malignant skin neoplasms in OTRs undergoing immunosuppression with AZA.

Methods: PubMed, Cochrane and Embase were searched for studies with OTRs who have a treatment regimen involving Azathioprine therapy after transplantation and that analyzed the emergence of skin neoplasia.

Skin cancers continue to present unresolved challenges, particularly regarding the association with sex hormones, which remains a topic of controversy. A systematic review is currently warranted to address these issues. To analyze if sex hormones result in a higher incidence of skin cancers (cutaneous melanoma, basal cell carcinoma, squamous cell carcinoma).

Abnormal melanin synthesis within melanocytes can result in pigmentary skin disorders. Although pigmentation alterations associated with inflammation are frequently observed, the precise reason for this clinical observation is still unknown. More specifically, although many cytokines are known to be critical for inflammatory skin processes, it is unclear how they affect epidermal melanocyte function.

Pilomatrix carcinoma (PC) is a rare malignant adnexal tumor originating from follicular matrix cells primarily impacting Caucasian males. This review provides a comprehensive analysis of scientific literature on PC through an exploration of 206 cases reported between 1980 and 2024. We discuss the epidemiology, clinical presentation, histopathology, and diagnostic challenges of PC, and explore various treatment methods for this rare malignancy as well as their associated outcomes.
