It involves the lymph nodes more commonly and rarely extranodal sites. The most common lymph node is cervical and usually presents as a painless asymptomatic mass. More often, it is a misdiagnosis, and there is a delay in treatment. It is rarely associated with Castleman disease, myasthenia gravis. Diagnosis of this condition is by histopathology and immunochemistry. Surgery is the primary modality of treatment, and adjuvant therapy has been tried with no definite trials due to the rarity of the disease. Here, we report a case of concomitant follicular dendritic sarcoma of the right cervical lymph node and papillary carcinoma of the thyroid managed in our institute. There was a line of investigations approaching towards a diagnosis, and she underwent total thyroidectomy and right modified radical neck dissection.<\/jats:p>","DOI":"10.1136\/bcr-2021-244175","type":"journal-article","created":{"date-parts":[[2021,11,17]],"date-time":"2021-11-17T11:30:53Z","timestamp":1637148653000},"page":"e244175","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Concomitant malignancies in the neck: follicular dendritic cell sarcoma; a rare tumour presenting as a right-sided neck nodal mass and papillary carcinoma thyroid"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8825-6032","authenticated-orcid":false,"given":"Suhas","family":"Umakanth","sequence":"first","affiliation":[{"name":"General Surgery, Kasturba Medical College Manipal, Manipal Academy of Higher Education, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0762-0427","authenticated-orcid":false,"given":"Badareesh","family":"Lakshminarayana","sequence":"additional","affiliation":[{"name":"General Surgery, Kasturba Medical College Manipal, Manipal Academy of Higher Education, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0307-5249","authenticated-orcid":false,"given":"Ranjini","family":"Kudva","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kasturba Medical College Manipal, Manipal Academy of Higher Education, Manipal, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,11,17]]},"reference":[{"key":"2025082622561023000_14.11.e244175.1","article-title":"A primary lymph node malignancy with features suggestive of dendritic reticulum cell differentiation.
