Plexiform fibromyxoma of the lesser curvature of the stomach in a 16‑year‑old adolescent: A case report and literature review

Le résumé fourni par la source

Gastric plexiform fibromyxoma (PF) is a rare mesenchymal tumor, with ~150 cases reported worldwide, predominantly occurring in the gastric antrum of adults.The present study describes a case of isolated PF in the lesser curvature of the stomach in a 16-year-old male patient.As confirmed by various multi-dimensional analyses of clinical, imaging and pathological data, the unique features of the case included its adolescent onset (only 12 cases of patients ≤18 years old have been reported globally) and the solitary localization in the lesser curvature of the stomach, with no previously documented cases.The patient presented with abdominal pain.A computed tomography scan revealed a solid intramural gastric mass with progressive enhancement.Postoperative pathology combined with immunohistochemistry (vimentin + , smooth muscle actin partially + , CD10 + and CD117/discovered on GIST-1 -) confirmed the diagnosis.No recurrence was observed during the 12-month follow-up.The present case expands the clinical spectrum of PF and emphasizes the value of multimodal diagnosis for tumors in rare locations.
