Background: Lichen planus (LP) can lead to severe scarring of the nail unit leading to anonychia. There are very few reports of squamous cell carcinoma (SCC) occurring in the lesions of ungual LP.
Objective: The aim of this study was to revise the previously reported cases of SCC appearing in ungual LP and to present a new case.
Methods: A PubMed search was performed with the terms "nail lichen planus" and "squamous cell carcinoma." Reported cases as well as a new case were depicted in a table.
Results: Only 2 indexed articles reporting 3 cases were found. All patients suffered of long-lasting scarring ungual LP.
Conclusions: The occurrence of SCC in nail LP is rare. LP is not "premalignant" per se, but SCC might rarely arise in LP scars.

Isthmoceles are defects related to Caesarean section (CS) scars, known to cause secondary infertility and interfere with in-vitro fertilization in women who have had Caesarean deliveries. The etiologies are multifactorial. Isthmoceles, similar to dehiscent CS scars, can be potential sites for ectopic pregnancies and abnormal placentation.

Metastasis is a major cause of poor prognosis of pancreatic cancer. Exosomes (Exos) regulate cancer progression by modulating macrophage polarization. This study aimed to investigate the effects of cancer-associated fibroblast (CAF)-released Exos on macrophage polarization in pancreatic cancer and the molecular mechanisms.

Objective: The Hispanic health paradox (HHP), the observation that Hispanic people in the United States often experience better health outcomes than non-Hispanic people despite having worse prognostic factors, has not been evaluated for patients with head and neck squamous cell carcinoma (HNSCC), a malignancy with marked racial disparities in outcomes. The objective of this study is to evaluate the HHP within the context of HNSCC.

Liver organoids have been increasingly adopted as a critical in vitro model to study liver development and diseases. However, the pre-vascularization of liver organoids without affecting liver parenchymal specification remains a long-lasting challenge, which is essential for their application in regenerative medicine. Here, the large-scale formation of pre-vascularized human hepatobiliary organoids (vhHBOs) is presented without affecting liver epithelial specification via a novel strategy, namely nonparenchymal cell grafting (NCG).

Introduction: This study compared the clinical outcomes of allogenic cultured limbal epithelial transplantation (ACLET) and cultivated oral mucosal epithelial transplantation (COMET) in the management of limbal stem cell deficiency (LSCD).
Methods: Forty-one COMET procedures in 40 eyes and 69 ACLET procedures in 54 eyes were performed in the Corneoplastic Unit of Queen Victoria Hospital, East Grinstead. Data were examined for demographics, indications, ocular surface stability, absence of epithelial defect, ocular surface inflammation, visual outcomes, and intra- and postoperative complications.
