This study aimed to evaluate the prevalence of shared risk factors, preventive behaviors, and the influence of couple dynamics on the early diagnosis of cutaneous melanoma (CM). Methods: We conducted a retrospective observational study at the San Gallicano Dermatological Institute IRCCS, Rome, enrolling 52 heterosexual couples diagnosed with CM between 2010 and 2023. Clinical and anamnestic data, including phototype, history of sun exposure, use of tanning devices, and reason for dermatological evaluation, were collected. Dermatological assessments included dermoscopy, total body photography, and histological examination of excised lesions. Statistical analyses were performed using chi-square and Student\u2019s t-tests. Results: Women reported significantly higher use of artificial ultraviolet sources (51.9% vs. 19.2%, p &lt; 0.001) and more frequent histories of sunburn. Phototype II was associated with higher use of tanning devices and a greater prevalence of sunburns. Although the CM stage did not significantly differ between sexes, husbands exhibited a greater Breslow thickness. Melanoma localization differed by sex, with lower limbs more often affected in women and the trunk in men (p &lt; 0.001). In 86.5% of cases, wives initiated their husband\u2019s dermatological evaluation, leading to earlier diagnosis. Conclusions: Despite shared environmental exposures, men and women differ in preventive behaviors and risk profiles. Women play a crucial role in promoting early detection among couples. Couple-based preventive strategies may be instrumental in improving early melanoma diagnosis and outcomes.<\/jats:p>","DOI":"10.3390\/diagnostics15151869","type":"journal-article","created":{"date-parts":[[2025,7,25]],"date-time":"2025-07-25T12:56:43Z","timestamp":1753448203000},"page":"1869","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevention Works Best in Pairs: An Observational Study on Connubial Melanoma"],"prefix":"10.3390","volume":"15","author":[{"given":"Alessandra","family":"Iorio","sequence":"first","affiliation":[{"name":"Department of Oncological and Preventative Dermatology, San Gallicano Dermatological Institute IRCCS, Via Elio Chianesi, 00144 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7249-2556","authenticated-orcid":false,"given":"Maria Concetta","family":"Fargnoli","sequence":"additional","affiliation":[{"name":"Department of Oncological and Preventative Dermatology, San Gallicano Dermatological Institute IRCCS, Via Elio Chianesi, 00144 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6038-2798","authenticated-orcid":false,"given":"Francesca","family":"Sperati","sequence":"additional","affiliation":[{"name":"UOSD Clinical Trial Center, Biostatistics and Bioinformatics, San Gallicano Dermatological Institute IRCCS, Via Elio Chianesi, 00144 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pasquale","family":"Frascione","sequence":"additional","affiliation":[{"name":"Department of Oncological and Preventative Dermatology, San Gallicano Dermatological Institute IRCCS, Via Elio Chianesi, 00144 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola","family":"De Simone","sequence":"additional","affiliation":[{"name":"Department of Oncological and Preventative Dermatology, San Gallicano Dermatological Institute IRCCS, Via Elio Chianesi, 00144 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1038\/s41437-019-0185-3","article-title":"Indirect assortative mating for human disease and longevity","volume":"123","author":"Rawlik","year":"2019","journal-title":"Heredity (Edinb)"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"De Simone, P., Bottillo, I., Valiante, M., Iorio, A., De Bernardo, C., Majore, S., D\u2019Angelantonio, D., Valentini, T., Sperduti, I., and Piemonte, P.
