Schwannomas are circumscribed, encapsulated usually benign tumours of nerve sheath found in the dermis of the subcutaneous tissue. Lid is an uncommon site, but few cases have been reported., The purpose of this paper is to report a case encountered in our routine surgical material.
A 19 years old Hindu, male presented with a small painless swelling in the left lower lid for the last 8 years. It was gradually increasing in size. There was no history of trauma. On examination, visual acuity was recorded as 6,'6 in both the eyes. A dumbel shaped swelling measuring about 10 mm x 5 mm was palpable in the left lower lid. It was situated 2 mm away from the ciliary lid margin and was firm, freely mobile and non tender [Figure 1]. The tumour was excised and submitted for histopathologic examination. The post operative period was uneventful. Macroscopically the specimen consisted of an encapsulated dumbel shaped firm mass, measuring 15 x 12 x 10 mms. Cut surface was grayish white with indistinct whorling, punctate haemorrhages and several soft yellowish foci. Microscopically, the tumour was composed of uniform sized spindle-celled interlacing fasciculi with areas which could distinctly be appreciated as Antoni A and Antoni B type of tissues. Foci of microcystic degeneration were also evident.
Regimentation of nuclei was observed in quite a few of the bundles [Figure 2]. Based on the histopathologic features, a diagnosis of benign Schwannoma was made.
Schwannomas usually occur as single and slow growing benign tumours thought to arise from the Schwann cells of the peripheral nerves involving commonly the cranial and spina nerve roots. Other sites involved include the face, neck, scalp and hands. Examples have been recorded in the tongue, palate and larynx While growing, they commonly assume an hour. glass form or the dumbel form as was seen it the present case. This case presented the classical morphologic features characterised by in, terlaced spindle-celled fasciculi, focal palisading of nuclei and the compact and loose textured Antoni `A' and Antoni `B' tissues. Once excised, the benign Schwannomas usually do not recur. Nath and Gogi reported a case which recurred after three years of its first removal, Their malignant counterparts are more rare. There may be pigmentation of the skin in cases of Schwannoma which indicates the close relationship of this tumour with von Reckling-hausen's disease, However, there was no associated lesion of any kind in the present case.
A case of benign Schwannoma which grew slowly for eight years in an uncommon site, the left lower eye lid, is described and discussed.
