Although most chronic wounds are associated with diabetes or chronic venous insufficiency, rare etiologies should also be considered. One such cause is envenomation by Phoneutria spp. (native to South America, rare in Europe). Their venom contains potent neurotoxins. While systemic manifestations are more commonly reported, localized necrotic skin lesions may also occur. This case report presents a rare chronic wound following a suspected Phoneutria spider bite and highlights the importance of an individualized, multimodal treatment approach. A 61-year-old male patient with a progressive thigh wound following a spider bite sustained during work. Despite initial self-treatment and pharmacotherapy the wound deteriorated. The patient was admitted to the authors\u2019 facility, where surgical treatment included necrosectomy and a sandwich graft using an acellular dermal matrix combined with a split-thickness skin graft. Adjunctive therapies included negative pressure wound therapy and hyperbaric oxygen therapy. After discharge, outpatient wound care was continued. Treatment was monitored with photographic documentation and serial microperfusion measurements. Complete wound closure was achieved after 4 months of specialized therapy. Management of chronic wounds requires a multidisciplinary and individualized approach with surgical intervention, advanced wound care and specialized outpatient follow-up.<\/jats:p>","DOI":"10.3390\/jcm15020693","type":"journal-article","created":{"date-parts":[[2026,1,15]],"date-time":"2026-01-15T08:26:36Z","timestamp":1768465596000},"page":"693","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Holistic Therapy in a Patient with Necrotic Ulcer Caused by the Bite of Brazilian Wandering Spider: A Case Report of Challenging Treatment with Combined Therapies"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4888-3179","authenticated-orcid":false,"given":"Anna","family":"Hepa-Banasik","sequence":"first","affiliation":[{"name":"Stanislaw Sakiel Burn Treatment Centre in Siemianowice \u015al\u0105skie, Jana Paw\u0142a II Street 2, 41-100 Siemianowice \u015al\u0105skie, Poland"},{"name":"Doctoral School of the Medical University of Silesia in Katowice, Faculty of Health Sciences in Bytom, Medical University of Silesia in Katowice, 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9042-3321","authenticated-orcid":false,"given":"Magdalena","family":"Szatan","sequence":"additional","affiliation":[{"name":"Stanislaw Sakiel Burn Treatment Centre in Siemianowice \u015al\u0105skie, Jana Paw\u0142a II Street 2, 41-100 Siemianowice \u015al\u0105skie, Poland"},{"name":"Doctoral School of the Medical University of Silesia in Katowice, Faculty of Health Sciences in Bytom, Medical University of Silesia in Katowice, 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3580-5629","authenticated-orcid":false,"given":"Anna","family":"S\u0142abo\u0144","sequence":"additional","affiliation":[{"name":"Stanislaw Sakiel Burn Treatment Centre in Siemianowice \u015al\u0105skie, Jana Paw\u0142a II Street 2, 41-100 Siemianowice \u015al\u0105skie, Poland"},{"name":"Doctoral School of the Medical University of Silesia in Katowice, Faculty of Health Sciences in Bytom, Medical University of Silesia in Katowice, 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaros\u0142aw","family":"\u0141ach","sequence":"additional","affiliation":[{"name":"Stanislaw Sakiel Burn Treatment Centre in Siemianowice \u015al\u0105skie, Jana Paw\u0142a II Street 2, 41-100 Siemianowice \u015al\u0105skie, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1063-9112","authenticated-orcid":false,"given":"Artur","family":"Wielg\u00f3recki","sequence":"additional","affiliation":[{"name":"Stanislaw Sakiel Burn Treatment Centre in Siemianowice \u015al\u0105skie, Jana Paw\u0142a II Street 2, 41-100 Siemianowice \u015al\u0105skie, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katarzyna","family":"Czerny-Bednarczyk","sequence":"additional","affiliation":[{"name":"Stanislaw Sakiel Burn Treatment Centre in Siemianowice \u015al\u0105skie, Jana Paw\u0142a II Street 2, 41-100 Siemianowice \u015al\u0105skie, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wojciech","family":"\u0141abu\u015b","sequence":"additional","affiliation":[{"name":"Stanislaw Sakiel Burn Treatment Centre in Siemianowice \u015al\u0105skie, Jana Paw\u0142a II Street 2, 41-100 Siemianowice \u015al\u0105skie, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,15]]},"reference":[{"key":"ref_1","first-page":"1902","article-title":"Venous leg ulcers","volume":"2016","author":"Nelson","year":"2016","journal-title":"BMJ Clin.
