We report intracranial fibrosarcoma which developed after radiotherapy for bilateral retinoblastomas. A 16-year-old boy was admitted with swelling of his left eyelid as his chief complaint on September 10, 1987. He had a past history of bilateral retinoblastomas at one year of age, which was treated by bilateral ophthalmectomy and postoperative radiotherapy; 50 Gy to right eye and 60 Gy to left eye. Until fifteen years old, he had no trouble except blindness. On admission, a dumb-bell type huge tumor with the destruction of the orbital roof was demonstrated on CT scan and MRI. The tumor was composed of solid orbital tumor and cystic tumor located in the left frontal lobe. On September 18, partial removal of the orbital tumor and evacuation of the intracranial cyst following embolization of the left external carotid artery was performed. The histological diagnosis of the tumor was fibrosarcoma. For the residual tumor, combined radiochemotherapy was carried out. The patient was treated with intravenous administration of 20 mg/m2 of cisplatin and 60 mg/m2 of VP-16 daily for five days and then whole brain radiotherapy of 26 Gy. On March 27, 1988, he obtained a complete remission of the tumor and was discharged without neurological deficit except blindness. In this case, we have presented a radiation-induced secondary tumor after a treatment of bilateral retinoblastomas. Although the tumor was highly proliferative and invasive fibrosarcoma, we could control it well by multimodality treatment including surgery, radiation and chemotherapy. It is noteworthy that combined chemotherapy with cisplatin and VP-16 was effective against this type of tumor.

This is the third case, reported in the literature, of transient cortical blindness that occurred during treatment of testicular carcinoma with cisplatinum, vinblastine and bleomycin. The presence of transiently pathological computerized tomography and brain scan suggests that this alarming event may not only be a toxic side effect of chemotherapy, but also a symptom related to eradicable subclinical metastases.

A primary bronchial tumor was diagnosed in six children younger than age 12 years. These cases include four bronchial carcinoids, a low-grade mucoepidermoid carcinoma, and a granular cell tumor ("myoblastoma"). Lobar or segmental resection was performed in each case and remains the treatment of choice. The most common bronchial tumors in childhood are carcinoids with 17 other evaluable cases in the English Literature. This series includes the youngest child to be reported with bilateral choroidal metastases leading to blindness; in addition, there were clinical manifestations of gigantism and acromegaly possibly related to ectopic hormone production. Low-grade mucoepidermoid carcinomas rank second in frequency to carcinoids and have an excellent prognosis. Judging from the childhood bronchial tumors reported to date, proved examples of bronchogenic carcinoma are vanishingly rare.

We report a case of nasopharyngeal carcinoma with brain metastasis of a 69-year-old man. The patient presented with blindness and a huge mass over right upper neck. The magnetic resonance imaging (MRI) showed right nasopharyngeal tumor and metastatic lesion in bilateral occipital regions. The bony x-ray showed diffuse osteoblastic metastases. The brain lesion was pathology-proven through the computed-tomographic guidance stereotactic biopsy.

The clinical value of lymph node immunohistochemistry was assessed in 343 consecutive patients with apparently node-negative breast cancer using antimucin monoclonal antibodies BC2, BC3 and 3E1.2. Occult metastases were detected in 41 patients (12 per cent). Although most of these were micrometastatic (< 2 mm in diameter), larger or diffuse deposits were found in ten patients. Blind assessment of repeat haematoxylin and eosin stained sections detected metastases in ten of the 41 patients with occult metastases. After a median follow-up of 79 months, patients with occult metastases had a shorter time to disease recurrence (P < 0.05) but not to death. After adjustment for other prognostic factors, the presence of occult metastases in two or more nodes was the most significant predictor of both disease recurrence (P < 0.01) and death (P < 0.01). When the ten patients with positive haematoxylin and eosin sections were excluded from the analysis, the presence of occult metastases in two or more nodes was still associated with a reduced disease-free interval (P < 0.05) and survival (P < 0.05). Lymph node immunohistochemistry is a simple technique affording more accurate definition of nodal involvement than conventional methods.

A case of primary parotid salivary gland adenocarcinoma is described in a three-year-old entire female great dane. The presenting complaint was sudden onset blindness concomitant with the development of bilateral hyphaema and anterior uveitis. A soft-tissue swelling of the left subaural region and right forelimb lameness were also present. A definitive diagnosis of primary parotid salivary gland adenocarcinoma with bilateral ocular metastases was made on post mortem examination. Metastases were also present in the right proximal humerus, left and right prescapular lymph nodes, left axillary lymph node, left retropharyngeal lymph node, bronchial lymph nodes and all lung lobes.

Breast cancer may affect the eye and orbit by metastatic neoplastic infiltration, uvea being the most common site of presentation. Management of these cases with radiotherapy is usually gratifying with reported response rate of approximately 75%. A retrospective evaluation of cases treated in five Institutions participating in a collaborative radiation therapy group of north-Italy is reported. Fifty-four cases of metastases to the eye or orbit were referred for radiation therapy to the Departments participating in the survey in the period 1977-1995. There were 49 female patients aged between 28 and 75 years (median, 44 years) at presentation of orbital metastasis. Thirty-eight lesions (70%) were metastases to the choroid, 9 involved other parts of the eye, and 7 patients had orbital metastases. Five of the 49 patients had bilateral choroidal metastases. Radiotherapy was employed with megavoltage equipment. The median total dose delivered was 40 Gy (range, 16-60 Gy). All the patients were treated 5 times per week with fraction sizes ranging from 1.8 to 3.0 Gy (median, 2.0 Gy). Of the 43 evaluable eyes, 34 (79%) showed a definite improvement after radiotherapy. There was a stabilization of the process in 4 patients. The rest (11 lesions) were lost to detailed follow-up of the response of the eye metastases. Twelve patients experienced acute transient cheratoconjunctivitis and in a case a subconjunctival haemorrhage was observed; as late side effects, two cases of chataract were observed during a period of observation of 37 and 117 months. A median survival time of 17 months was observed. The goal of irradiation was to improve vision or at least prevent blindness and enucleation. The palliative effect of irradiation was confirmed with a response rate consistent with the data of the literature on this subject.

A male mixed breed dog of unknown age was presented with sudden onset of blindness and a slightly exophthalmic right eye. Ophthalmoscopically, a spherical, pinkish mass protruding from the region of the optic disc into the vitreous was seen in the right eye. Ultrasound and computer tomography demonstrated an extension of the mass into the right retrobulbar space, continuing intracranially to the optic chiasm. Cytologic findings, obtained by ultrasound-guided fine needle aspiration from the retrobulbar space, were consistent with myxosarcoma. On the basis of these findings of a well-delineated mass in the brain stem area, irradiation was planned as the therapy of choice. The dog was treated under general anesthesia using a proton beam at the Paul Scherrer Institute (PSI, Villigen, Switzerland). A curative protocol (56 Gy in 16 fractions over 4 weeks, 3.5 Gy/fraction) was used. Twenty-seven days post radiation therapy the dog was euthanized, as clinical symptoms progressed. Enlargement of the intracranial tumor was seen on a CT study repeated on the day of euthanasia. A gross pathologic and histologic examination were performed and confirmed the diagnosis of a myxosarcoma involving the eye, retrobulbar space of the right side, and the optic chiasm. Post-mortem examination failed to identify any abnormalities or metastases elsewhere in the body.

Epidermodysplasia verruciformis (EV) is a hereditary disease that has served as a model for viral-induced carcinogenesis. Patients with EV have an increased susceptibility to infection with human papillomavirus, which results in the development of benign lesions in childhood. The lesions may resemble tinea versicolor in appearance and distribution, and usually remain benign. However, later in life cutaneous squamous cell carcinoma may develop on sun-exposed areas, such as the forehead. Radiation therapy may not only result in the malignant conversion of EV lesions, but may also increase the risk of metastases. To our knowledge, this is the first report of a patient with EV in whom squamous cell carcinoma of the conjunctiva developed. His clinical course was complicated by ocular invasion causing blindness, metastasis, and eventually death.

A 2-year-old boy with blindness as an isolated symptom was found to have no light perception binocularly because of compression of both optic nerves by a neuroblastoma infiltrating the walls of the optic canals and medial sphenoid bone. Imaging disclosed a primary tumor near the kidney and multiple osseous metastases. Although neuroblastoma commonly causes blindness by metastasis to the orbit, it rarely causes bilateral blindness from intracranial compression of the optic nerves. This is the first report of bilateral blindness as the presenting feature.
