Leiomyosarcoma of the iris is rare. Blodi (i964) doubted the occurrence of malignant myomata in the iris. Ashton (i964) described four cases of leiomyosarcoma as almost certainly malignant. The invasive properties of one of the neoplasms described were so obvious, that it was considered the most definitely malignant (Fig. i). The patient from whom this neoplasm was removed recently attended the...

A newborn baby had an orbital-intracranial benign teratoma radically excised with preservation of the eye. Three years later she developed recurrent proptosis, and reoperation showed an invasive orbital tumour that histologically was a malignant germ-cell neoplasm. The relationship of the two tumours is discussed. Malignant change in a benign orbital-intracranial teratoma of the newborn has not...

PURPOSE Natural killer (NK) cell neoplasm is a rare disease that follows an acute course and has a poor prognosis. It usually emerges from the nose and appears in the ocular tissue as a metastasis. Herein, we describe a case of NK-cell neoplasm in which the eye was considered to be the primary organ. CASE A 50-year-old female displayed bilateral anterior chamber cells, vitreous opacity, bullo...

Background: Giant cell tumor is a benign but locally aggressive bone neoplasm which uncommonly involves the skull. Giant cell tumor (GCT) of the sphenoid bone is relatively rare. In this report, we describe a tumor of the greater wing of left sphenoid bone. Case presentation: A 31-year-old female was presented with headache, proptosis and diplopia of her left eye. Cranial magnetic resonance ima...

Orbital liposarcoma is a rare and usually unsuspected neoplasm. Over a five-year period three female patients aged 22, 71, and 77 years presented with primary myxoid liposarcoma of the orbit. The management of one patient was complicated by a history of orbital decompression for suspected thyroid eye disease. The tumour infiltrates locally beyond a deceptive pseudocapsule, and surgery has to be...

Burkitt’s lymphoma is a malignant neoplasm rarely found in paranasal sinuses and skull base. We report a rare case of Burkitt’s lymphoma of anterior skull base associated with acute loss of vision. A 10 years old boy presented with history of headache, diminution of vision in right eye since 15 days. Biopsy showed diffuse NHL of Burkitt’s type. After treatment with chemotherapy there was comple...

Case Report Male ultramarine worker, aged 41.-In October, 1943, biopsy from a tumour in the left breast showed a spheroidal-celled carcinoma, and a radical mastectomy with skin grafting was performed followed by deep x-ray therapy. In March, 1951, episcleritis. developed in the left eye; the visual acuity was found to be 6/6 and the episcleritis settled under local treatment. By August, 1951, t...

A 39-year-old Caucasian woman with a history of recurrent conjunctival melanoma of her right eye developed an intrastromal heavily pigmented malignant melanoma, which involved the whole corneal diameter. The patient was treated by corneoscleral lamellar keratoplasty and there has been no evidence of recurrent neoplasm during 4 years of follow-up. This apparently unique presentation of malignant...

a set of one hundred and twenty nine patients with known primary malignancy and suspected brain metastasis was reviewed in present study. the patients were selected among patients presented to the mri section of imam khomeini hospital or a private mri center in tabriz (iran). primary tumor site, clinical manifestations, number and site of lesions were identified in this patient population. the ...

There are presented results of the complex NLS-research of patients with space-occupying lesions of orbital and extra-orbital genesis which were confirmed by the results of the clinical research, MRT and CT scanning and also morphologically verified in patients who had underwent surgery. It is determined that spectral-entropic analysis of tissues structure of spectral parameters of blood circul...
