MPTT may occur in younger patients and at atypical sites; malignant transformation should be suspected in long\u2010standing trichilemmal lesions. This case underscores the need for more extensive studies on MPTT to better understand its epidemiology, associated systemic conditions, diagnostic evaluation, and therapeutic strategies. Early recognition and treatment are essential to prevent recurrence and metastasis.<\/jats:p>","DOI":"10.1002\/ccr3.72631","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T07:07:26Z","timestamp":1777446446000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Malignant Proliferating Trichilemmal Tumor: A Rare Case Report and Review of Literature"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-1488-1549","authenticated-orcid":false,"given":"Chanda","family":"Shrestha","sequence":"first","affiliation":[{"name":"Department of Dermatology Nepal Medical College and Teaching Hospital  Kathmandu Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sweta","family":"Sah","sequence":"additional","affiliation":[{"name":"Department of Dermatology Nepal Medical College and Teaching Hospital  Kathmandu Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8723-2346","authenticated-orcid":false,"given":"Deepika","family":"Neupane","sequence":"additional","affiliation":[{"name":"Department of Dermatology Nepal Medical College and Teaching Hospital  Kathmandu Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6464-1128","authenticated-orcid":false,"given":"Sandesh","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of Dermatology Nepal Medical College and Teaching Hospital  Kathmandu Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8408-7547","authenticated-orcid":false,"given":"Smriti","family":"Piya","sequence":"additional","affiliation":[{"name":"Cutis Care Skin Care and Hair Transplant Clinic  Kathmandu Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3122-2346","authenticated-orcid":false,"given":"Mohan","family":"Bhusal","sequence":"additional","affiliation":[{"name":"Department of Dermatology Nepal Medical College and Teaching Hospital  Kathmandu Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"issue":"7","key":"e_1_2_12_2_1","article-title":"A Proliferating Trichilemmal Tumor at an Uncommon Site Treated With Radical Excision: A Case Report and Literature Review","volume":"16","author":"Boeisa A.
