Carcinoid tumors are slow growing, low-grade malignant neoplasms that are believed to originate from neuroendocrine cells, usually in the gastrointestinal mucosa.
Metastasis
of carcinoid tumor to the orbit is a rare occurrence. When metastasis does occur, the choroid is the most common ocular structure involved. We report two cases of unique involvement of extraocular muscles.

Medulloepitheliomas are rare congenital tumours arising from the epithelium lining the medullary tube. They are usually detected in the first decade of life. They may be teratoid or non-teratoid. Regional and distant
metastases
are rare. Extraocular extension of disease appears to be the most important prognostic feature. Surgical resection is the usual mode of treatment. The role of other adjuvant modalities is as yet unclear.

Merkel cell carcinoma (trabecular cell carcinoma) is a rare, distinct, primitive, neuroendocrine malignancy of the skin, usually affecting elderly patients. It develops from Merkel cells and nearly one out of every 10 Merkel cell carcinomas occurs in the eyelids and periocular region. The tumor manifests itself clinically as a bulging lesion near the lid margin, painless, reddish colored with teleangiectatic blood vessels on the surface. Histologically, the tumor can mimic malignant lymphoma, undifferentiated melanoma, sebaceous carcinoma or cutaneous
metastases
of pulmonary microcytoma. Immunohistochemical studies with antibodies to neuron-specific enolase, cytokeratins and neurosecretory granules are necessary to differentiate these tumors. One third of all Merkel cell carcinomas result in death. In the present paper, we present data on the clinical features, treatment and long-term follow-up of three patients.

Malignant tumors of the orbit and the orbitomaxillary region constitute 4-8% of head and neck malignancies. The lesions can be primary orbital malignant tumors or can invade the orbit from the eyelids, the eyeball or the paranasal sinuses, especially the maxillary sinus and ethmoids. The commonest primary malignant tumors of the orbit are lymphomas, rhabdomyosarcomas and lacrimal gland epithelial tumors. These tumors are excluded from the present study since their management differs from that of metastatic tumors. Our experience is based on a series of 48 patients operated during the last five years. There was an equal distribution according to both age and sex, with two-thirds of the patients being over 60 years of age. Histologically, the basal cell carcinomas (B.C.C.) prevailed with 19 cases, followed by squamous cell carcinomas (Sq.C.C.) in 12, adenocarcinomas (AdenoCa) in 10 and orbital melanomas (O.M.) in 7. In 13 cases the maxilla was also affected. Surgical treatment varied from exenteration to wide cran iofacial resections; immediate reconstruction followed in all cases. Only 10 patients were treated with surgery alone. In the remaining 38 patients radiotherapy was given, alone or in combination with chemotherapy. The surgical techniques included exente ration with split-thickness skin grafting in 19 cases, exenteration with coverage with median forehead flap in 16, and maxillectomy with forehead and temporalis flaps in 7 cases. The tumors recurred in 12 patients, all of them in the first postoperative year. Ten patients died from intracranial involvement or distant
metastases
. In six of these patients the lesions were Sq.C.C., in two AdenoCa and in two O.M. It is concluded that the surgical treatment of orbital and orbitomaxillary malignancies, although subject to broad guidelines that determine the operability of the tumors, should be individualized according to the extent of the lesion and the experience of the surgeon.

A 65-year-old man with sudden profound loss of vision in his right eye due to sub-periosteal orbital haemorrhage was found to have disseminated intravascular coagulation (DIC) secondary to metastatic prostatic carcinoma. CT-scan did not reveal any orbital
metastases
. A lateral canthotomy did not help to restore the vision. Orbital haemorrhage is known to occur with DIC due to different causes. To the best of our knowledge this is the first report of orbital haemorrhage with DIC related to prostatic carcinoma. This case emphasises the importance of considering systemic factors in cases of non-traumatic haemorrhage, along with imaging studies to rule out any co-existing vascular anomaly.

Primary cutaneous mucinous carcinoma of the eyelid is an adenocarcinoma of the eccrine glands. It is rare and locally aggressive but the prognosis following local excision, confirmed with tumour-free margins, is good. This tumour is usually described in the elderly. We present the occurrence, clinical and histological features, and management of this tumour in a young male.A 36-year-old male presented with a small cystic right lower lid lesion, which had increased in size and pigmentation over two years. He underwent excision biopsy for diagnostic purposes followed by Moh's micrographic surgical removal. The defect was repaired with an upper eyelid skin graft. A full oncological screen including whole-body computed tomography scan excluded the presence of primary mucinous carcinoma elsewhere and any metastatic spread. There has been no recurrence of tumour 18 months following excision. Ophthalmologists should be aware of the occurrence of this tumour in a younger age group than previously described. Moh's micrographic surgery is the most suitable method of treatment following exclusion of both distant primaries and
metastases
.

A 53-year-old male presented with a progressive mass of the left orbit. His medical history included an invasive carcinoma of the bladder diagnosed three weeks earlier. An orbital biopsy was performed and the diagnosis was that of an orbital metastasis of urinary bladder carcinoma. The patient developed widespread
metastatic disease
and unfortunately died one month after the diagnosis of orbital metastasis. Orbital metastasis of urinary bladder carcinoma is associated with a poor prognosis and is more frequently observed in older people. In addition, it is five times more prevalent in men than in women.

Metastasis
to the orbital soft tissues is relatively uncommon. We report a rare case of renal cell carcinoma with orbital metastasis as the first clinical manifestation. A 48-year-old-man presented with left proptosis and complete ptosis of three weeks duration. Radiological examination revealed a left intraconal heterogeneous cyst-like lesion with rim enhancement immediately deep to the left superior rectus muscle. Diagnosed as having orbital cysticercosis, he was prescribed oral albendazole and prednisolone. But there was no clinical improvement. An incisional biopsy performed showed metastatic poorly differentiated carcinoma. The patient complained of backache and weight loss in the interim. Magnetic resonance imaging (MRI) of the spine showed extensive vertebral metastasis to the thoracic and lumbosacral spine and the iliac bone, with an incidental detection of a large mass from the right kidney. Further MRI of abdomen and chest showed a large right renal mass presumed to be a renal cell carcinoma with extension into the right renal vein, intra-abdominal lymph nodes, and peritoneum. There were small nodules in the lung suggesting the possibility of pulmonary metastatic deposits. Renal cell carcinoma does not respond to chemotherapy, immunotherapy, or radiation; because of the disease's advanced stage, the patient received palliative treatment. There have been only two other reports in the literature of metastatic renal cell carcinoma in the orbit where the proptosis was the initial presenting feature similar to our case.

A 35-year-old lady presented with recurrent episodes of painful right upper lid swelling and ptosis of 6 months' duration. The symptoms would subside with oral antibiotics and painkillers. She had also been undergoing treatment for one year for multiple painful osteolytic lesions in the long bones and axial skeleton for which no definite diagnosis had been made, despite several radiological and serological investigations having been performed. Computed tomographic scan showed a soft tissue lesion in the superolateral part of the right orbit with erosion of the adjacent bone. Lacrimal gland biopsy showed non-specific inflammatory changes. She was referred for full work-up to exclude lymphoma and metastasis. Magnetic resonance imaging revealed an enhancing soft tissue mass in the right anterior cranial fossa eroding the lateral orbital wall and extending into the orbit. Another mass encased the superior sagittal sinus. Bone marrow biopsy showed near total replacement of marrow cells by a round cell tumour. Immunohistochemical studies revealed that the tumour cells expressed neuron specific enolase and chromogranin. The pathological findings suggested a diagnosis of neuroendocrine tumour though neuroblastoma could not be unequivocally ruled out. (131) I-metaiodobenzylguanidine scan showed no uptake. Radiologic studies suggested multiple bony
metastases
. No other site of primary tumour was found so there was a strong possibility of it being a primary orbito-cranial neurogenic tumour. Neuroblastomas and neuroendocrine tumours are very rare in adults. The orbit is an unusual site for a primary of this nature. In addition, it is quite difficult to make a specific diagnosis in a less differentiated tumour.
