ARPD is strongly associated with systemic diseases such as diabetes mellitus (DM) and chronic renal failure, which may contribute to ARPD through factors including microcirculatory disturbances and the deposition of metabolic byproducts, including advanced glycation end-products and calcium. Here, we report a case of ARPD that improved following DM treatment and catheter-based interventions for peripheral artery disease (PAD). The eruptions on the upper limbs significantly improved with DM management. On the other hand, lesions on the lower limbs showed marked improvement after the enhancement in arterial blood flow due to catheter surgeries, along with DM treatment. Although a few reports of ARPD improving with DM management exist, our case underscores the importance of adequate DM control in ARPD management. The inability to perform the biopsy of the lesions on the lower limbs is our limitation; however, these lesions, similar to those on the upper limbs, presented with a central keratotic plug and re-epithelialized without forming ulcers or erosions, suggesting they were also related to ARPD. To date, there has been little discussion on the relationship between blood flow impairment in major vessels and ARPD. However, hypertension and venous circulatory dysfunctions are considered to lead to ARPD, raising the possibility that PAD-induced microvascular disturbances might have facilitated lesion formation in the present case. Further accumulation of cases and research is needed to clarify the relationship between blood flow impairment in major vessels and ARPD.<\/jats:p>","DOI":"10.3390\/medicina61010036","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T13:26:25Z","timestamp":1735651585000},"page":"36","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Case of Acquired Reactive Perforating Dermatosis with Complete Resolution of Eruptions on Upper and Lower Limbs During the Treatment of Diabetes Mellitus and Peripheral Artery Disease"],"prefix":"10.3390","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4832-1899","authenticated-orcid":false,"given":"Yoshihito","family":"Mima","sequence":"first","affiliation":[{"name":"Department of Dermatology, Tokyo Metropolitan Police Hospital, Tokyo 164-8541, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsutomu","family":"Ohtsuka","sequence":"additional","affiliation":[{"name":"Department of Dermatology, International University of Health and Welfare Hospital, Tochigi 329-2763, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ippei","family":"Ebato","sequence":"additional","affiliation":[{"name":"Department of Dermatology, International University of Health and Welfare Hospital, Tochigi 329-2763, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryosuke","family":"Nishie","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, International University of Health and Welfare Hospital, Tochigi 329-2763, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Uesugi","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, International University of Health and Welfare Hospital, Tochigi 329-2763, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makoto","family":"Sumi","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, International University of Health and Welfare Hospital, Tochigi 329-2763, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshimasa","family":"Nakazato","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology, International University of Health and Welfare Hospital, Tochigi 329-2763, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7649-0806","authenticated-orcid":false,"given":"Yuta","family":"Norimatsu","sequence":"additional","affiliation":[{"name":"Department of Dermatology, International University of Health and Welfare Narita Hospital, Chiba 286-8520, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"766","DOI":"10.1111\/j.1468-3083.2006.02085.x","article-title":"Familial reactive perforating collagenosis: A clinical, histopathological study of 10 cases","volume":"21","author":"Ramesh","year":"2007","journal-title":"J.
