Introduction: In recent years, techniques with minimally invasive have been gradually developed and used in the diagnosis of lymphoma. Among minimally invasive techniques, core needle biopsy (CNB) has been widely accepted as an effective tool for the diagnosis of malignant lymphoma, carcinoma and deep tumors that are only accessible via CT or endoscopic-guided. This study was conducted to investigate of diagnostic value of ultrasound guided CNB in the diagnosis of lymphoma in all parts of the body compared to surgical excisional biopsy (SEB). Materials and Methods: This is an descriptive epidemiological study that was performed on patients with suspected lymphoma referred to the intervention ward of Golestan Hospital in Ahvaz in 2019. For all patients with suspected lymphoma, CNB of lymph nodes was performed by ultrasound-guided. Finally, the final diagnosis of CNB was compared with the results of surgical biopsy in the studied specimens. Results: In this study, 40 patients were evaluated with suspected lymphoma. At initial diagnosis with CNB, 12 (30%) had NHL, 19 (47.5%) had Hodgkin's lymphoma, and 2 had high-grade lymphoma. Of the 40 patients examined, 29 required IHC to confirm the diagnosis. In 8 cases, the final diagnosis was done using SEB. Final diagnosis in 9 (22.5%) patients was confirmed by CNB only. The CNB along with the IHC also led to the final diagnosis in 23 (57.5%) patients. However, another 8 patients required biopsy to confirm the diagnosis by SEB. Conclusion: The findings of this study indicated that US-CNB is a highly efficient method of diagnosis of lymphoma with high specificity, in the fastest possible mode and with the least complications.
