We read the recent article titled ”Primary Hydatid Cyst of the adrenal gland: A case report and a review of the literature” published by Zouari and colleagues with great interest [1]. The authors have presented a case of left adrenal hydatid cyst (AHC) disease in a 55 years old patient together with a review of literature. We would like to commend the authors for the detailed literature review. However, we would like to emphasize a few points regarding the study. The first point we would like to emphasize is about the reference list of the study. The authors have made a literature search on the PubMed and they state that they have found 39 studies regarding the adrenal AHC disease. They have summarized the studies in Table-1. However, the authors should have included these 39 studies in the reference list or should have submitted the list as a separate supplemental file such as an “appendix”. This would have enabled these studies to obtain a citation. For instance, two studies from our institution (belongs to the leading author of the commentary) have been used in the literature review of the authors but it was not present in the reference list of the authors. This neglects the efforts of the authors that have performed the cited research and also is an ethical problem. Therefore, we would like to send you an appendix that includes all the 39 studies that have been used by the authors for their literature review summarized in Table-1. This reference list that we have prepared should be added to the study of Zouari and colleagues; which would be very appropriate under these circumstances. The second point that we would like to emphasize involves the content of the article. The analysis of Table-1 of the authors showed that at least two of the studies used in the literature review are misinterpreted. The authors have stated that Limaiem and colleagues [2] have reported 55 years old female patient that was operated for a 12 cm sized left AHC. However, if the text of the mentioned article is examined in detail it will be seen that the lesion is “epithelial adrenal cyst”. Similarly, the authors state that Darwish and colleagues [3] have reported 30 years old pregnant female patient treated for 12 cm sized right AHC. However, the text of mentioned article states that the lesion was actually ”endothelial adrenal cyst”. The third point that we would like to emphasize is about the errors regarding the ages and gender of the patients given in Table1. The study by Akbulut and colleague [4] reported a patient who was 16 years old but was stated as 64 years old in the Table-1. On the contrary, the study by Seidel and colleagues [5] states that the patient was 64 years old but was reported as 16 years old in Table1. The gender of the patient reported in the study by Fitzgerald and colleague [6] states that the patient was female but it was reported c g A
