Sunitinib and TB lymphadenitis: An unexpected link in oncological therapy: a case report.

Rationale: Gastrointestinal stromal tumors (GIST) are neoplasms that originate from the interstitial cells of cajal located in the muscular layer of the gastrointestinal tract. Surgery is the primary treatment options; however, if resection is not feasible, or in cases of metastatic or recurrent GIST, systemic chemotherapy can be considered as an alternative. Sunitinib, a multi-targeted tyrosine kinase inhibitor, is indicated as an essential second-line treatment for GIST following disease progression or intolerance to imatinib mesylate.
