The genetic underpinning of skin mucinous carcinoma is presently unknown. Here, we sought to define whether the repertoire of somatic mutations of a primary mucinous carcinoma of the skin would be similar to that of mucinous breast carcinomas, given the histologic similarities between these tumor types.Methods and ResultsThe tumor was situated in the dermis and partially involved the subcutaneous fat. Tumor cells were suspended in periodic acid–Schiff diastaseresistant- positive mucin lakes and expressed cytokeratin 7, synaptophysin and estrogen receptor. DNA samples extracted from microdissected tumor and matched normal tissue were subjected to massively parallel sequencing targeting 410 cancerrelated genes. The skin mucinous tumor was found to have a low tumor mutation burden, but to harbor a clonal GATA3 frameshift mutation (p.T418Hfs*89) and amplification of FOXA1, genes not uncommonly altered in breast mucinous carcinomas.ConclusionsIn this primary skin mucinous carcinoma, GATA3 and FOXA1 driver genetic events were identified, consistent with a possible developmental relationship between skin and breast mucinous neoplasms.","journal":"EJC Skin Cancer","year":2023,"id":378039,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9444,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":259317,"name":"Maria Rosaria De Filippo","orcid":"0000-0001-8350-2599","position":1,"is_corresponding":false},{"id":1142435,"name":"Chaido Sirinian","orcid":null,"position":2,"is_corresponding":false},{"id":242195,"name":"Pier Selenica","orcid":"0000-0003-0086-0513","position":3,"is_corresponding":false},{"id":1142436,"name":"Maria Repanti","orcid":null,"position":4,"is_corresponding":false},{"id":14428,"name":"Jorge S.
