“…They are benign, non-infiltrating tumors with limited or no local recurrence and no ability to metastasize to other organs, so the prognosis is favorable. 1,4,8,9 In conclusion, plexiform schwannoma is a rare entity that tends to settle in soft tissues of the head and neck, being infrequent visceral involvement. These are well-defined single lesions with marked hypercellularity and positive for S-100.…”

“…There are numerous variants of schwannoma, such as: cellular, epitheliod, plexiform, glandular or melanocytic, among others; being the plexiform variant infrequent, with an estimated incidence of approximately 5% of all schwannomas. 1,3,5 The plefixorm variant use to be unique lesions with a variable size. There is no predilection for any sex.…”

“…Among the most commonly affected intrabdominal organs are the esophagus and the colon, and only one case of plexiform schwannoma located in the duodenum has been described in the reviewed literature. 1,5 These are tumors with little clinical expression that occur with vague symptoms as abdominal discomfort, intermittent episodes of intestinal bleeding or, more rarely, intestinal obstruction. In our case, the patient debuted with a clinic of high intestinal obstruction with postprandial vomiting, epigastric pain and weight loss.…”

“…Plexiform schwannoma is a tumor with benign behavior originated in the sheath of peripheral nerves composed of Schwann cells that are arranged in palisade. [1][2][3][4][5] It is considered an unusual variant, with an approximate incidence of 4-5% of all schwannomas. They are usually well-defined, localized lesions on the skin or the subcutaneous tissue and settle in decreasing order in the head and neck, upper and lower limbs.…”

Plexiform schwannoma is a benign tumor originated in the sheath of the peripheral nerves that is composed of Schwann cells that are arranged in palisade. These lesions usually arise from the skin being less frequent in intraabdominal organs. We describe, according to the reviewed literature, the second case of plexiform schwannoma arising from the duodenum. A 49 year old patient with a history of vomiting, diffuse abdominal discomfort and weight loss. The complementary tests were inconclusive. The patient was operated evidencing in the operation room a stenosis of the third duodenal portion without any other alterations. The pathological anatomy reported a submucosal lesion formed by multiple nodules composed by a proliferation of spindle cells that were positive for S-100.

“…PS is frequently located in superficial soft tissues or the cutaneous region (3). Visceral involvement is extremely rare (3%) and only a few cases involving the abdomen/digestive tract have been reported to date (2,8). The first case of visceral PS (ascending colon) was reported by Hirose et al in 1997 (9).…”

Visceral plexiform schwannoma: A case series

et al. 2020

Plexiform schwannoma (PS) is a benign tumour of the peripheral nerve sheath that is typically found in the skin. Fewer than 15 cases of visceral PS have been reported to date in both adults and children. We herein discuss a series of 3 patients (2 male and 1 female) with abdominal PS, aged 10-16 years (mean age, 12 years). All the patients had an acute presentation with abdominal pain, which was associated with rectal bleeding in 1 case and with walking difficulties in 1 case. Radiological investigations included abdominal magnetic resonance imaging (MRI) and computed tomography, along with neurofibromatosis screening (cerebral MRI and dermatological evaluation). Complete removal of the mass was possible in 2 of the patients (in 1 case by laparoscopically assisted surgery). Follow-up was uneventful. Abdominal PS is a rare occurrence. Due to its possible association with neurofibromatosis, the diagnosis of PS should prompt an investigation for other manifestations of this disorder.
