Appendicular schwannoma presenting as vague abdominal pain

Appendicular schwannomas are very rare condition with nonspecific clinical symptoms and frequently recognized during pathological examination. They arise less frequently in the gastrointestinal tract and comprise ~1% of all malignant gastrointestinal tumours. We presented a rare case of an appendicular schwannoma that was discovered incidentally in a 25-year-old student diagnosed with appendicular mucocoele with a suspected obstructing tumoural lesion based on computed tomography findings. A colonoscopy examination showed a bulging, nodular, erythematous lesion at the base of the caecum (appendiceal orifice). Biopsies showed mixed inflammatory infiltration in the lamina propria, with lymphoid-filled formations. No evidence of dysplasia or neoplasia. Tumour markers were negative. Appendicular neoplasms, such as schwannomas of the appendix, are rarely associated with nonspecific clinical symptoms and are frequently recognized during pathological examination of the resected appendix. Laparoscopic surgery with a clear resection margin is the cornerstone of treatment for appendicular schwannoma, and it is associated with a favourable prognosis.
