“…However, some schwannomas may become malignant as they grow in size. In fact, malignant cases were confirmed in 2 out of the 17 cases discussed here [9,13]. Notably, only a few cases reported on long-term prognosis of patients, and effective treatment methods other than resection have not been studied.…”

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.

“…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].…”

Diaphragm tumors are rarely encountered. The most common benign tumor is lipoma, while the most frequent malignant tumor is fibrosarcoma. These tumors are generally seen in the 5th decade of life, and tumor incidence in equal in both sexes. There are no clinical characteristic signs as the diaphragm is adjacent to many organs. This is why a radiologically spotted mass usually causes confusion as to which organ it is associated with. Because of the difficulty in diagnosis, minimally invasive procedures like video-assisted thoracoscopy (VATS) and laparoscopy can be used. Primary treatment option for all malignant and benign diaphragm tumors is surgery. Combination therapy is suggested in locally advanced tumors; however, the survival time is short. Key words: Diaphragm, tumor, surgery ÖzetDiyafram tümörleri çok nadir görülen tümörlerdir. En sık rastlanan selim tümörü lipom, malign tümörü ise fibrosarkomdur. Kadın/erkek görülme oranı eşit olup, 40-50 yaş aralığında daha sık rastlanır. Diyaframın bir çok organa komşu olmasına bağlı tümörlerinin karakteristik bir kliniği yoktur. Bu yüzden radyolojik tespit edilen kitlenin hangi organa ait olduğu da çoğunlukla karışır. Tanı koymak zor olduğundan, video yardımlı torakoskopi (VATS) ve laparoskopi gibi minimal invaziv yöntemlerden de faydalanılabilinir. Tüm malign, benign diyafram tümörlerinde primer tedavi cerrahidir. Lokal ileri evre tümörlerde kombine tedavi önerilse de sağkalım kısadır.

An uncommon tumor of the diaphragm malignant schwannoma

Abstract: Primary neoplasms of the diaphragm are rare. Neurogenic tumors of the diaphragm, particularly those showing malignant degeneration are quite rare. We report herein a case of a 48-year-old woman, who was found to have a malignant schwannoma of the diaphragm.
