Initially misdiagnosed as pigmented purpura, the need for further investigation arose to determine the nature of the condition accurately. The medical evaluation encompassed a comprehensive analysis of the patient's skin ailment. A series of diagnostic examinations were conducted to ascertain the underlying cause. Although routine blood tests yielded unremarkable results, the distinct characteristics of the rash prompted a more thorough investigation. Subsequent assessment revealed that the skin condition was not pigmented purpura, as initially presumed, but rather a manifestation of cutaneous T\u2010cell lymphoma (CTCL) known as mycosis fungoides (MF). MF is an infrequent lymphoma predominantly affecting individuals aged 45\u201365, exhibiting a male\u2010to\u2010female sex ratio of 2:1. The annual incidence of MF ranges from 0.3 to 0.96 cases per 100,000 individuals. The woman's skin exhibited discrete patches adorned with colored dots, progressively thickening and pigmentation. Notably, the absence of pruritus did not dispel suspicion. This case underscores the significance of accurately diagnosing uncommon dermatological disorders to facilitate appropriate medical intervention. The unique appearance of the rash and its distinctive features, despite normal blood results, enabled the identification of MF. The patient's treatment encompassed a combination of steroids and narrowband UV therapy. Vigilance, continued research, and heightened awareness are paramount for early intervention and improved patient outcomes. Such efforts contribute to an enhanced understanding of the complexities of this condition.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccr3.8847","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T08:53:51Z","timestamp":1716195231000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Mimicry unveiled: The challenging diagnosis of pigmented purpura\u2010like mycosis fungoides initially misdiagnosed as pigmented purpura"],"prefix":"10.1002","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3482-5636","authenticated-orcid":false,"given":"Sabita","family":"Aryal","sequence":"first","affiliation":[{"name":"Department of Dermatology, Shanghai Skin Diseases Hospital Tongji University  Shanghai China"},{"name":"Shanghai Skin Diseases Hospital, School of Medicine Tongji University  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0808-2974","authenticated-orcid":false,"given":"Jiang","family":"Zhu\u2010qian","sequence":"additional","affiliation":[{"name":"Department of Dermatology Shanghai Jiading Hospital of Traditional Chinese Medicine  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3758-1390","authenticated-orcid":false,"given":"Liu ye","family":"Qiang","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Shanghai Skin Diseases Hospital Tongji University  Shanghai China"},{"name":"Shanghai Skin Diseases Hospital, School of Medicine Tongji University  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4632-5153","authenticated-orcid":false,"given":"Md Ariful","family":"Haque","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Yan'an Hospital Affiliated to Kunming Medical University  Kunming Yunnan China"},{"name":"Department of Public Health Atish Dipankar University of Science and Technology  Dhaka Bangladesh"},{"name":"Voice of Doctors Research School  Dhaka Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.21037\/cco.2018.10.02"},{"key":"e_1_2_13_3_1","unstructured":"AlibertJL.Description des Maladies de la Peau: Observees l'Hospital St. Louis et Exposition des Meilleurs Methods Suiview pour leur Traitement.
