Diagnosis is often incidental in tonsillectomy specimens sent to the pathology laboratory for varied diseases. This is a 10-year study of tonsillectomy specimens diagnosed with actinomycosis. Specimens were formalin-fixed and paraffin processed and stained with haematoxylin and eosin, gromott methenamine silver and periodic acid\u2013Schiff. Four cases of tonsillar actinomycosis were diagnosed from a total of 772 tonsillectomy specimens. Histologically, characteristic oeosinophilic granules with peripheral radial protuberances surrounded by microabscesses were seen. Tonsillar actinomycosis is often an incidental diagnosis; however, a high index of suspicion should be entertained in patients with recurrent tonsillitis and\/or tonsillar hypertrophy of unknown cause.<\/jats:p>","DOI":"10.4103\/npmj.npmj_325_22","type":"journal-article","created":{"date-parts":[[2023,8,27]],"date-time":"2023-08-27T23:52:59Z","timestamp":1693180379000},"page":"262-264","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Incidental Histopathological Diagnosis of Tonsilar Actinomycosis: A Report of Four Cases"],"prefix":"10.4103","volume":"30","author":[{"given":"Modupeola Omotara","family":"Samaila","sequence":"first","affiliation":[{"name":"Department of Pathology, Faculty of Basic Clinical Sciences, College of Medical Sciences, Ahmadu Bello University, Zaria, Nigeria"},{"name":"Department of Pathology, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamarudeen","family":"Sani","sequence":"additional","affiliation":[{"name":"Department of Pathology, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nurudeen Adebola","family":"Shofoluwe","sequence":"additional","affiliation":[{"name":"Division of Otorhinolaryngology, Department of Surgery, Faculty of Clinical Sciences, Ahmadu Bello University, Zaria, Nigeria"},{"name":"Department of Otorhinolaryngology, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ifusumu Yirom","family":"Rimamskep","sequence":"additional","affiliation":[{"name":"Department of Pathology, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2023,8,29]]},"reference":[{"key":"R1-20240908","doi-asserted-by":"crossref","first-page":"372","DOI":"10.1016\/j.otorri.2009.01.010","article-title":"Tonsillar actinomycosis manifested as expectorated debris","volume":"60","author":"Soler Sendra","year":"2009","journal-title":"Acta Otorrinolaringol Esp"},{"key":"R2-20240908","first-page":"3","article-title":"Actinomycosis with tonsilar diseases and its clinical significance","volume":"7","author":"Maharja","year":"2017","journal-title":"Glob J Otolaryngol"},{"key":"R3-20240908","doi-asserted-by":"crossref","first-page":"30","DOI":"10.21037\/ajo-19-38","article-title":"The role of tonsillar actinomycosis in adult patients","volume":"3","author":"Hari","year":"2020","journal-title":"Aust J Otolaryngol"},{"key":"R4-20240908","doi-asserted-by":"crossref","first-page":"1261","DOI":"10.1001\/jama.1910.04330150021008","article-title":"The etiology of actinomycetes.
