Here, we report a case of a 53-year-old woman with a history of sub-optimally controlled diabetes mellitus presenting with fevers and decreased Glasgow Coma Scale (GCS) to a tertiary hospital. She was diagnosed with diabetic ketoacidosis (DKA), with blood glucose at 40 mmol\/L and ketones at 7 mmol\/L, in the setting of a methicillin-sensitive\n                      <jats:italic>Staphylococcus aureus<\/jats:italic>\n                      necrotising soft tissue back infection. Her medical history included diabetes managed with insulin but no engagement with an endocrinologist or allied health support. Examination revealed an infected, necrotic back wound on her left mid-upper back that required surgical debridement and broad-spectrum IV antibiotics. In addition, she exhibited marked plantar keratoderma and onychogryphosis, reportedly present and worsening over approximately two years. She was prescribed 40% urea cream twice daily, resulting in gradual sloughing of the hyperkeratotic skin within a few weeks. Her HbA1c was 10.4%, and she tested negative for diabetes antibodies, indicating type 2 diabetes. Treatment included an insulin\u2013dextrose infusion until DKA resolved, followed by twice daily insulin degludec\/aspart (Ryzodeg 70\/30) and metformin. The PPK was attributed likely secondary to sub-optimally managed diabetes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Learning points<\/jats:title>\n                    <jats:list list-type=\"bullet\">\n                      <jats:list-item>\n                        <jats:p>Diabetes mellitus has multiple complications, including rare dermatologic manifestations such as PPK.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>This case illustrates the importance of thorough skin assessments in patients with diabetes, particularly those that have a history of sub-optimal diabetes control.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>A multidisciplinary approach, integrating dermatology, endocrinology and allied health services such as podiatry, is essential in managing diabetes-related complications, improving patient quality of life and preventing further complex manifestations.<\/jats:p>\n                      <\/jats:list-item>\n                    <\/jats:list>\n                  <\/jats:sec>","DOI":"10.1530\/edm-24-0088","type":"journal-article","created":{"date-parts":[[2025,1,27]],"date-time":"2025-01-27T06:43:25Z","timestamp":1737960205000},"update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-2","source":"Crossref","is-referenced-by-count":1,"title":["Severe palmoplantar keratoderma: a cutaneous complication from sub-optimally controlled type 2 diabetes"],"prefix":"10.1530","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9210-8028","authenticated-orcid":true,"given":"Fatima","family":"Iqbal","sequence":"first","affiliation":[{"name":"Department of Diabetes and Endocrinology, Westmead Hospital, Sydney, New South Wales, Australia"},{"name":"College of Medicine, Alfaisal University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Phan","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Westmead Hospital, Sydney, New South Wales, Australia"},{"name":"Discipline of Medicine, Randwick Clinical Campus, University of New South Wales (UNSW) Sydney, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wah N","family":"Cheung","sequence":"additional","affiliation":[{"name":"Department of Diabetes and Endocrinology, Westmead Hospital, Sydney, New South Wales, Australia"},{"name":"Faculty of Medicine and Health, University of Sydney, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","reference":[{"key":"bib1","series-title":"DermNet NZ","article-title":"Palmoplantar keratoderma","author":"Stanway A","year":"2005","unstructured":"Stanway A Palmoplantar keratoderma.
