Three consecutive cases of lacrimal gland carcinoma seen at the University Hospital during a twelve-year period are presented. One case was unusual, presenting at the age of sixteen years and developing metastases to the lungs. Adenoid cystic carcinoma is the commonest type of lacrimal malignancy and its clinico-pathological features and surgical management are discussed.
Primary corneal myxoma is extremely rare. It has only been reported on 2 previous occasions. Secondary corneal myxomas are more common, arising from corneal diseases such as infective keratitis, keratoconus, and bullous keratopathy. Myxomas occur commonly in other soft tissues such as the heart, paranasal sinuses, and muscles but can rarely present in periocular structures including the conjunctiva, orbit, and eyelid. Ours is only the third case of primary corneal myxoma reported in the literature and illustrates several unusual features. These include an inferonasal location between the corneal epithelium and Bowman layer and with no relationship to the corneal stroma, rapid tumor growth over a 3-month period, and no previous ocular trauma or conjunctival pathology. The histology of this lesion has an important part to play in the management of this condition as it determines the cellular origin, establishes a benign or malignant state, and helps with treatment and prognosis. One reported case of primary corneal myxoma recurred within 2 months after local resection. This was treated with bandage soft contact lens, and no recurrence had been reported since. Our case is now 12 months post op and has had no recurrence.
We report a case of an adult who presented with progressive swelling in the right eye with suggestive of intracranial lesion on imaging. Histopathological revealed a lacrimal gland malignant mixed tumour.
We report a very rare case of recurrent nasopharyngeal carcinoma with local involvement of lacrimal sac. The patient was treated with chemotherapy and there was no recurrence noted after 1 year of follow-up.
A total of 89 histopathologically proven ocular tumours and tumour-like lesions treated in Hospital University Sains Malaysia, Kubang Kerian, Kelantan over a period of nine years were reviewed for their age distribution, site of lesion and histological type. The tumours were observed in all age groups with a maximum prevalence in the first decade. Twenty lesions were malignant and 69 were benign. The eyelid was the most frequent location (51%), followed by the conjunctiva (32%). Retinoblastoma was the most common malignant tumour (10 cases) and dermoid cyst was the most common tumour-like lesion (16 cases).
A rare case of choroidal malignant melanoma in a naevus of Ota is described. This is the first reported case from Asia outside the Japanese population. This case illustrates the need for close observation of all pigmented lesions of the eye.
Breast carcinoma is the most common primary tumor producing intraocular metastasis. Metastases to the iris and ciliary body are relatively rare. The authors report a case of a 61-year-old lady, operated for carcinoma of the left breast 3 years back, who presented with symptoms and signs of acute narrow-angle glaucoma in the right eye. A diffuse whitish plaque-like mass in the upper nasal quadrant of the iris with an episcleral nodule on the limbus in the corresponding area and all the signs of acute narrow-angle glaucoma were present in the right eye. Intraocular pressure was controlled medically. Fine-needle aspiration cytology from the episcleral nodule showed malignant cells. Histopathology of the excised nodule showed metastatic poorly differentiated carcinoma, and the cellular pattern was similar to the carcinoma of the breast. There was no other metastasis anywhere in the body. Fine-needle aspiration cytology from an external lesion of the eye is a less invasive and easier procedure than paracentesis to diagnose the metastatic nature of the lesions. The rare features in our case are the clinical presentation as acute glaucoma and the ocular structures being the first and only site of metastasis.
