Haemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening condition characterised by widespread immune system activation, resulting in tissue damage throughout multiple organ systems. HLH is categorised into primary HLH, arising from intrinsic defects in lymphocytes and macrophages, and secondary HLH, primarily triggered by infections or connective tissue disorders. HLH is one of the rarest complications of scrub typhus. We present the case of a previously healthy young man who presented to our facility with a history of acute febrile illness. Clinical examination revealed an eschar and subsequent laboratory investigations confirmed the diagnosis of scrub typhus. The patient\u2019s haematological parameters showed pancytopenia, raising suspicion of this rare association. Confirmatory tests established the diagnosis of HLH, and the patient achieved an uneventful recovery following treatment for the underlying illness and supportive care.<\/jats:p>","DOI":"10.1177\/14782715241303969","type":"journal-article","created":{"date-parts":[[2024,12,9]],"date-time":"2024-12-09T01:18:51Z","timestamp":1733707131000},"page":"23-27","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Secondary haemophagocytic lymphohistiocytosis associated with scrub typhus: A case report with a brief review of literature"],"prefix":"10.1177","volume":"55","author":[{"given":"Rupak","family":"Chatterjee","sequence":"first","affiliation":[{"name":"Department of Tropical Medicine, Calcutta School of Tropical Medicine, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3809-8926","authenticated-orcid":false,"given":"Atanu","family":"Chandra","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Bankura Sammilani Medical College, Bankura, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumana","family":"Mukherjee","sequence":"additional","affiliation":[{"name":"Department of Pathology, Calcutta School of Tropical Medicine, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nandini","family":"Chatterjee","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, IPGMER and SSKM Hospital, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sugata","family":"Dasgupta","sequence":"additional","affiliation":[{"name":"Department of Critical Care Medicine, IPGMER and SSKM Hospital, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,12,8]]},"reference":[{"issue":"5","key":"e_1_3_2_2_2","article-title":"Scrub typhus: an emerging threat","volume":"62","author":"Chakraborty S","year":"2017","unstructured":"Chakraborty S, Sarma N.
