Abstract
PURPOSE Chronic inflammation is a predisposing factor for metaplastic changes and ultimately dysplasia. We describe cases of OSSN occurring in the setting of chronic ocular surface inflammation. METHODS Sixteen eyes from 14 individuals were included from one ocular oncology clinic between 2010 and 2023. Patients presented with ocular surface squamous neoplasia (OSSN) in the setting of chronic inflammation. The diagnosis of OSSN was made using anterior segment high-resolution optical coherence tomography (HR-OCT) and confirmed by histopathological analysis in all cases. RESULTS Median age on presentation was 61 [IQR 47.5-69.2] years. Eleven (86%) individuals were male and five (36%) identified as White Hispanic. Ten eyes were referred with ocular surface diagnoses including pannus (n = 4), scarring (n = 3), pterygium (n = 2), and herpetic keratitis (n = 1). Only six eyes were referred as possible neoplasia. All individuals had a history of ocular surface inflammation. The most common inflammatory conditions were ocular rosacea (seven individuals) and atopic keratoconjunctivitis (AKC) (five individuals). Two individuals were found to have bilateral OSSN, one in the setting of ocular rosacea and the other in the setting of AKC. All 16 eyes from 14 individuals were suspected to have OSSN based on HR-OCT findings which guided the location of the incisional biopsies that subsequently confirmed histopathological diagnosis in all cases. CONCLUSION OSSN may arise in the setting of chronic inflammation on the ocular surface. Identification of the tumor can be challenging in these cases, and HR-OCT can be a key diagnostic tool in detecting OSSN.

Yuan X, Sheng L, Shi G, Jiang L, Lian C. Colchicine Alleviates Rosacea by Inhibiting Neutrophil Inflammation Activated by the TLR2 Pathway. Inflammation 2024; 47:1002-1014. [PMID: 38279067 DOI: 10.1007/s10753-023-01956-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 12/21/2023] [Accepted: 12/23/2023] [Indexed: 01/28/2024]
Abstract
Rosacea is a chronic facial inflammatory skin disease that occurs with dysfunction of the immune system. Colchicine was reported to have anti-inflammatory properties. However, the impact of colchicine on rosacea remains unclear. In the present study, the phenotype of rosacea lesions was evaluated by the redness score, inflammatory biomarkers were analyzed by reverse transcription PCR (RT‒PCR), and the infiltration of inflammatory cells was assessed by IHC analysis and immunofluorescence in a rosacea-like mouse model. In vitro, RT‒PCR was used to identify the inflammatory factors that Toll-like receptor 2 (TLR2) agonist caused neutrophils to produce, and immunofluorescence and coimmunoprecipitation were used to identify putative signalling pathways. We found that skin erythema and histopathological alterations, as well as elevated proinflammatory factors (IL-1β, IL-6, TNFα, CXCL2) and CAMP, were significantly ameliorated by colchicine treatment in LL37-induced rosacea-like mice. In addition, colchicine reduced the colocalization of TLR2 and neutrophils and the formation of neutrophil extracellular trap networks (NET) in mouse lesions. In neutrophils, colchicine markedly reduced TLR2 agonist-induced inflammatory biomarker expression, NET formation, and ROS production. Moreover, we found that LL37 could bind to TLR2 upon activation of TLR2 in neutrophils. Importantly, colchicine could repress the combination of TLR2 and LL37 in vivo. Finally, bioinformatics methods further validated the key molecules of neutrophil-related inflammation in rosacea, which is consistent with our experimental findings. Collectively, colchicine ameliorated rosacea-like dermatitis by regulating the neutrophil immune response activated by the TLR2 pathway, indicating that it could be an effective therapeutic option for patients with rosacea.

Abstract
Morbihan syndrome (MS) is characterized by solid facial edema, usually related to rosacea or acne vulgaris. The facial edema deforms the patient's features, can impair peripheral vision, and affects quality of life. Its pathophysiology remains unclear. The disease usually has a slow and chronic course. MS most commonly affects middle-aged Caucasian men with rosacea and is rare in people below 20 years of age. MS is a diagnosis of exclusion. There is no standard treatment for MS, though systemic isotretinoin and antihistamines are mainly used. We present the case of an adolescent girl with MS nonresponding to 19 months of isotretinoin treatment with add-on antihistamines. Therapy with monthly administration of omalizumab (anti-IgE) for 6 months was an effective therapeutic option, improving the quality of life. Our case is the second description of omalizumab use in Morbihan syndrome, the first in an adolescent.

Abstract
Rosacea is a chronic skin disease prevalently affecting the center of the face. The permanent erythema of skin face represents its typical sign. Further common features are face flushing, telangiectasias, and inflammatory presence of oedema, papules and pustules. The aim of this study was to investigate the use of LBO 532nm laser in the treatment of this disease. Ten subjects of both sex and middle age affected by rosacea in erithemato/teleangectatic stage were treated by a LBO 532nm laser single session. Discomfort evaluation during and after the treatment, one session results as well as incidence of the side effects were evaluated, with 6 months follow up. Positive results were obtained after only one session in total safety with minimal patients discomfort and without undesired effects during treatment. The study confirmed International literature data suggesting the use of laser and light devices as elective treatment of this disease. IPL, dye lasers and 532nm laser are the devices more used and the last seems to represent the gold standard for 1,2,3 phototypes. This clinical trial, with the limitations due to the small number of patients, indicated that “one session LBO 532nm laser treatment” represents an interesting and innovative approach in the therapy of the erythemato/telangectatic rosacea.
