A histological examination of the lesion was performed to resolve the difficulty in removing this pigmentation. No granuloma reaction, including giant cells, was observed in the lesion tissue, even after such a long course and significant pigmentation. Granuloma formation in this disease may be a functional problem of the patient\u2032s histiocytes and\/or phagocytes rather than its chronic course or excessive hemosiderin deposition. Similarly, hyperlipidemia did not affect granuloma formation.<\/jats:p>","DOI":"10.1155\/crip\/5536378","type":"journal-article","created":{"date-parts":[[2026,2,11]],"date-time":"2026-02-11T06:21:17Z","timestamp":1770790877000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Case Report of Pigmented Purpuric Dermatosis With No Granuloma Formation: A 20\u2010year Follow\u2010Up Case Study"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6805-7084","authenticated-orcid":false,"given":"Yasuhiro","family":"Horiuchi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,10]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10112283"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/dth.15854"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/cup.13118"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/ddg.13228_g"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0b013e31823f616a"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-3083.2010.03627.x"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/cup.14224"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.1951.01570080061009"},{"key":"e_1_2_12_9_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-immunol-032712-100022"},{"key":"e_1_2_12_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2013.10.009"},{"key":"e_1_2_12_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0901-5027(88)80158-9"},{"key":"e_1_2_12_12_2","first-page":"173","article-title":"Association Between Hemosiderin Deposition and Blood Vessel Regression During Involution of Foreign-Body Granuloma.
