Abstract

Sebaceous carcinoma of meibomian gland is not so common as is generally re ported. In general feature of this tumor may masquerade as a chronic blepharoconjunctivitis or a chalazion for many months before the true diagnosis is esta blished. In the case of orbital involvement secondarily the patient may occasion ally develop as solid nodule in the fossa of the lacrimal gland that may simulate a primary gland tumor, The authors experienced one case of sebaceous carcinoma which developed in the orbital area. This was a 23-rear-old female who had a growing large mass in the left orbital area, which caused proptosis and decreased vision. Computed tomography of the left orbit demonstrated a large soft tissue mass lesion, about 3 X 3 X 1.5 cm in size, in superotemporal side of the retroorbital portion. The patient underwent a lateral orbitotomy and excisional biopsy of the tumor. Microscopic examination showed intracytoplasmic lipoid vacuoles and mixed pattern which was an admixture of lobular and comedocarcinoma-like area. About 2 months later the tumor recurred, so subtotal orbital exenteration with preservation of lid, conjunctiva, cornea and sclera was undertaken and radiotherapy was taken. However, this tumor was extended to brain.
