  Introduction Top


Lacrimal gland tumors constitute about 7%--Moss and McMillan (1962) and 16%-Das (1963 as a cause of unilateral proptosis in adults and older age groups.

The various types of lacrimal gland tumors as described by Reese are: 1. Mixed tumors. 2. Muco-epidermoid. 3. Carcinoma. 4. Miscellaneous forms. Out of these, the mucoepidermoid variety is by far the least common and only one such case has been re­ported by Reese (1956) in his series of lacrimal gland tumors.

Because of its rarity the following case merits reporting.


  Report of the Case Top


A female patient aged 45 years pre­sented in the eye out patient depart­ment for the first time on 13.10.1965 with the complaints of (1) gradual pro­trusion of the left eye ball for the past 1 ½ years, more so, for the last six months. (2) History of attacks of mild pain in the left eye, left temporal and mandibular regions for the last 5 to 6 months. (3) History of `splitting' of vision while looking upwards, inwards, and outwards for the past five to six months. There was no history of ex­cessive sweating, tremors, palpitation. swelling in the neck, or of fever.

Past History

Two years back she had injury to the left eye with her own hand result­ing in redness, pain, watering which persisted for only 7-8 days. For the last 18 years she has been getting attacks of complete unconsciousness occa­sionally lasting for a few hours (hys­terical according to the opinion of a Neuro-physician). There was also occa­sional swellings of feet, legs, and face for the same duration.

Personal and Family History

She is a housewife, of good economic status, coming from Abohar, District Ferozepore. Her mother had hyper­tension and hemiplegia. There was no history of diabetes, tuberculosis or epi­lepsy in the family.

General Examination.

She was obese. Her pulse was 92 per minute and regular, and her blood pressure 145/80 mm of Hg. There was oedema of her legs upto the junction of middle and upper third which pitted on pressure. There was no significant enlargement of glads anywhere.

Local Examination

Left Eye. The palpebral fissure was wider than the right one. In addition to forward protrusion the eye was directed slightly downwards and in­wards also, 1 mm of scleral ring being visible above the limbus [Figure - 1]. The cornea was normal in size, shape, cur­vature, transparency and sensitivity. The pupil was regular and reacting normally.

Vision: Finger counting from 1 foot, with good projection of light. The patient spoke of a "splitting of im­age" in up, in and out directions. Eye ball movements were completely re­stricted on the outer side, while in upward and inward directions very slight movements were present, but in downward direction full movements were full. The sense of touch and pain on the face were equal on both sides. No thickening was noticed of temporal bony area. There was no pulsation in the exophthalmos, no cranial bruit. Fundus was normal.

Right Eye. Nothing abnormal was de­tected.

Investigations

Haemoglobin was 11.45 gms%. The total lucocytic count was 10200 p/c mm, the differential count showed no abnormality. E.S.R. was 2 mm, first hr. (Westergreen), serum chole­sterol 250 mg X-Ray skull for sphe­noidal ridge showed no abnormality. Nothing abnormal was detected in the stools and a trace of albumin was, pre­sent in the urine with occasional epi­thelial and pus cells.

Treatment and Progress

No definite cause of unilateral prop­tosis was detected, so lateral orbito­tomy was done on 20.10.65 with the help of a Neuro-surgeon. A spherical cyst 3/4 of an inch in diameter, was enucleated intact, lying behind and superior-temporally in the orbit. [Figure - 2]. There was no connection with the orbital or palpebral part of the lacri­mal gland. On cutting it, only straw coloured fluid came out of the cyst; no hair was seen.

Histopathological Report

Section shows a fairly well encap­sulated tumor. The tumor is made of sheets of epidermoid cells [Figure - 3] with little stroma. In other regions acini containing P.A.S. positive mate­rial are seen [Figure - 4],[Figure - 5]. The acini are small and regular, or dilated and cystic. The two elements: epidermoid and mucous secreting glands are intimately mixed up with each other.

Diagnosis: Muco epidermoid tumor.

After the operation, the proptosis subsided and the movements of the eye ball attained almost a normal range. Vision improved to finger counting to 2-3 feet. No splitting of image was complained of.

Edema of lids and of temporal re­gion subsided in about a week's time.

The patient on the 10th day com­plained of loss of sensation in a small area 2 x 1/2" horizontally above the Zygomatic arch-which was confirmed by the absence of pain and touch sen­sation in that area. On confrontation test, the field of vision was found to be restricted especially on the outer side. The patient was discharged on 10-11-65.


  Comments Top


Mucoepidermoid tumor usually arises in the duct of lacrimal gland and contains both mucous secreting and epidermoid cells. It was first described by Steward, Foote and Backer (1945) in the salivary glands. They claim an incidence of little more than 5 % of all salivary gland tumors. According to these authors benign and malignant forms occur. The benign variant is composed of proliferating mucous cells, basket cells and columnar cells. The undifferentiated epidermoid carci­noma is rapidly growing and highly malignant. The classical type of growth may be solid or cystic, may be encapsulated or non-encapsulated and ori­ginates from cells of larger and inter­mediate ducts. Microscopically it is characterised by an abnormal differ­entiation into mucous cells and epider­moid metaplasia. Keratin pearl forma­tion may occur.

In the present case, the tumor ap­peared to arise either from the duct of the lacrimal gland or from some aberrant glands in the orbit.


  Summary Top


A case of unilateral proptosis due to muco-epidermoid tumor of the lacri­mal gland is reported which was re­moved by lateral orbitotomy with satisfactory post operative result.
