Sir,

We came across a rare case of appendicular schwannoma in a child that prompted us for presentation.

A 12-year-old male child presented with a history of mass and pain in the lower abdomen since 1 year. On examination, a large mobile mass was palpated in the right lower abdomen. Ultrasound examination revealed a hyperechoic mass in the right lower abdomen. Computerized tomography (CT) demonstrated a highly enhancing well-defined mass in the right lower abdomen measuring 10cm in diameter [Figure 1a]. The mass showed prominent blood vessels all over its surface. Ultrasound-guided fine needle aspiration cytology (FNAC) was performed from the mass, which showed some clusters of spindle-shaped cells against a myxomatous background. Grossly, the tumor was well encapsulated, nodular, 10 9cm and attached to the tip of the appendix [Figure 1b]. The cut surface was solid grayish white and lobulated. Histological examination revealed dense cellular areas arranged in sheets and whorls (Antoni A type pattern) alternating with more loosely structured area (Antoni B type pattern). Additionally, the tumor showed a large number of blood vessels and inflammatory cell infiltrate [Figure 2]. Immunohistochemically, the tumor showed strong positivity for S-100 protein. Thus, a final diagnosis of benign appendicular schwannoma was made. The post-operative period was uneventful and the patient was doing well after surgery.

Schwannoma is a benign neurogenic tumor arising from the sheath of the peripheral nerves. [1] Although it is a frequent tumor, it is seldom found in the abdomen. [2],[3] Only few cases of lesser omentum, greater omentum and mesenteric schwannoma have been reported so far. [4],[5]

Abdominal schwannoma may cause diagnostic problems because clinical symptoms are misleading or uncharacteristic even if the tumor is large. Although clinical imaging includes plain film radiography, ultrasound and selective angiography, CT scan and magnetic resonance imaging remain the imaging modalities of choice. In summary, schwannoma of the appendix may present as abdominal mass without producing much symptoms and making its pre-operative diagnosis difficult. This case is a pointer to the unusual site of presentation of benign schwannoma. Because of a paucity of literature in this younger age group, this case is being reported here.
