The tumour on the scalp of an 84\/year\/old white woman was excised and histological examination showed typical features of PTT, but with a coexistent malignant spindle\/cell tumour with a sarcomatoid appearance. There were some areas of transition between squamous trichilemmal epithelium and the neoplastic mass composed of atypical spindle\/shaped cells. Two years later, the patient was well, and neither recurrence nor metastases were observed. We report the second case of PTT with a malignant spindle\/cell transformation with a sarcomatoid appearance (spindle\/cell carcinoma), and a proven aneuploidy, demonstrated with DNA\/flow cytometric analysis.<\/jats:p>","DOI":"10.2340\/0001555573444446","type":"journal-article","created":{"date-parts":[[2023,7,6]],"date-time":"2023-07-06T10:08:41Z","timestamp":1688638121000},"page":"444-446","source":"Crossref","is-referenced-by-count":23,"title":["Malignant aneuploid spindle\/cell transformation in a proliferating trichilemmal tumour."],"prefix":"10.2340","volume":"73","author":[{"given":"M","family":"Alvarez-Qui\u00f1ones","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M F","family":"Garijo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F","family":"Fern\u00e1ndez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J F","family":"Val-Bernal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1183","published-online":{"date-parts":[[1993,12,1]]},"container-title":["Acta Dermato-Venereologica"],"original-title":[],"link":[{"URL":"https:\/\/medicaljournalssweden.se\/actadv\/article\/download\/16578\/20444","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medicaljournalssweden.se\/actadv\/article\/download\/16578\/20444","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,16]],"date-time":"2023-11-16T07:47:29Z","timestamp":1700120849000},"score":1,"resource":{"primary":{"URL":"https:\/\/medicaljournalssweden.se\/actadv\/article\/view\/16578"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,12,1]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[1993,12,1]]}},"URL":"https:\/\/doi.org\/10.2340\/0001555573444446","relation":{},"ISSN":["1651-2057","0001-5555"],"issn-type":[{"value":"1651-2057","type":"electronic"},{"value":"0001-5555","type":"print"}],"subject":[],"published":{"date-parts":[[1993,12,1]]}}}
