Sir,

We read with great interest the case report by Jesús Rocha-Maguey et al. entitled “A new case of cervical intramedullary sinus histiocytosis causing paraplegia and review of the literature.”[ 5 ] In their article, the authors revealed that their patient was the 6th case that presented with an isolated intramedullary mass without any systemic manifestation. They listed information regarding all 6 reported cases. However, we found some mistakes that existed in this article or some doubts that need to be explained.

First, the authors have cited an article reported by Sandoval et al.,[ 6 ] and they searched the English literature using PubMed and SCOPUS from the period 1970 to July 2013 in their article. They found 2 cases (Osenbach/1996[ 4 ] and El Molla/2014[ 2 ]) that presented as an isolated intramedullary Rosai–Dorfman disease (RDD). These two cases were also listed in Jesús Rocha-Maguey's article. Even though the case reported in Sandoval's article was not an isolated intramedullary RDD, it was included in Jesús Rocha-Maguey's cases. In fact, the patient had lesions in the left cavernous sinus and right prepontine cistern with mass effect over the pons and pontomedullary junction.[ 6 ]

Second, Jo-Ann W. Andriko et al.[ 1 ] pointed out that the case reported by Jones et al.[ 3 ] (the second case listed in Table 1 by Jesús Rocha-Maguey et al.) was the same as Osenbach et al.,[ 4 ] Jo-Ann W. Andriko, Jones and Osenbach were all from the same institute namely Walter Reed Army Medical Center, Washington, DC.

Therefore, the patient in the article by Jesús Rocha-Maguey's et al.[ 5 ] should be the 4th case that presented as isolated intramedullary RDD.

Isolated intramedullary RDD is a rare clinical entity, and during reporting of such rare cases, attention should be given to correct and accurate reporting of data with complete information. Such debatable reporting of rare cases makes the credibility of a reputed journal like this esteemed journal to be questioned. Furthermore, we think it is imperative to keep the data correct and authoritative and maintain the credibility of such esteemed journal like Surg Neurol Int.
