“…We acquired 36 records, from which 20 articles were excluded because of obvious irrelevance, narrowing the list down to 16 case reports. Finally, including our case, 17 cases of primary diaphragmatic schwannoma were collected, and their summary is provided in Table 1 [2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Background Schwannomas are nerve sheath tumors that commonly originate from the stomach and small intestine. A primary schwannoma of the diaphragm is rare and does not show any symptoms until it grows to a certain size. Hence, it is extremely rare that it was found at a size that allowed resection under videoscopic surgery. Case presentation A 77-year-old woman was referred to our department for surgical treatment of a tumor located near the gastric fornix. She underwent a routine esophagogastroduodenoscopy 2 years and 7 months prior to the referral. It was suspected that she had a submucosal tumor measuring 10 mm, located in the fornix, and was then referred to her previous physician. During her follow-up, endoscopic ultrasonography (EUS) revealed that the cystic structure had continued to grow toward the gastric wall, and she was then referred to the endoscopy division of our hospital. She continued to be followed-up, and it was noted that the tumor was gradually increasing in size. Therefore, she requested surgical resection, and was finally referred to our division. Since the tumor was rather small, we planned a laparoscopic surgery. An initial examination during the operation revealed that the tumor was located on the left diaphragm. Since the tumor was relatively small and visibility was good, we decided to continue with the laparoscopic surgery. Partial diaphragmectomy with complete inclusion of the tumor was performed, and the defect of the diaphragm was directly closed by a running suture. Pathological examination revealed a benign schwannoma that had originated from the diaphragm. To support our findings, we also reviewed the scientific literature on diaphragmatic schwannoma cases reported up to April 2020. Conclusions In this extremely rare case, we successfully resected the diaphragmatic schwannoma using laparoscopic surgery.

“…These tumors usually seen in the adults between the ages of 20 and 50 but can be seen in any age group including children. [8] Patients are generally asymptomatic and diagnosis may be misleading on routine investigations. Diaphragmatic neurilemmomas are very rare and represent approximately 3% of all diaphragmatic neoplasm thus, only very few cases have been reported.…”

“…To the best of our knowledge, only 13 cases have been reported in the literature of diaphragmatic neurilemmomas (Table 1). [2][3][4][5][6][7][8][9][10][11][12][13][14][15] However present case is unique one, as this is the first case having such kind of dilemma in its initial presentation, where initially there was no clue regarding involvement of diaphragm but during surgical exploration and with final histopathological examination, whole scenario was changed. No other previous report had showed such kind of initial presentation.…”

Neurilemmomas are benign, slow growing, encapsulated nerve sheath tumor. These tumors arise from the schwann cells of neural crest. Neurilemmomas can manifest in various form according to site, extent and severity of involvement of organ. Diaphragmatic neurilemmomas are very unusual and even difficult to diagnose on preoperative imaging. We will report a case of 39 year old male, who presented with complaints of occasional left flank pain for one year and subsequently investigated, which showed left adrenal cyst with haemorrhagic fluid content. On the contrary, when surgical exploration of the lesion was done, it showed a cyst within the diaphragm, completely separated from left kidney and left adrenal with haemorrhagic content in situ. Histopathological examination of the lesion showed it to be a benign neurilemmoma with cystic degeneration. Post opearatively patient did well. We believe that this is the first case report, which is addressing such kind of initial manifestation of diaphragmatic neurilemmomas.

“…Primary schwannoma of the diaphragm is exceedingly rare, with less than 10 cases reported to date; three cases were reported in the pediatric population and one case was reported of a malignant schwannoma. [3][4][5] We report a case of primary schwannoma of the diaphragm identified on surveillance imaging for a history of lung cancer and diagnosed after resection via a thoracoscopic approach.…”
