Metastatic brain tumors from colorectal cancer are relatively rare. In previous reports the incidence ranged from 1.9 to 3.5 percent of all metastatic brain tumors. In another recent article the cumulative incidence of brain metastasis was estimated at 1.2%. The prognosis for patients with even a single resectable brain metastasis is poor. This paper presents the case report of a 72-year-old woman with a solitary brain metastasis 16 years after a diagnosis of colorectal cancer. She remained asymptomatic for 16 years. The first sign of a secondary tumor was diplopia. Brain scan demonstrated a space-occupying lesion in the occipital area. A solitary tumor was removed by craniotomy. Histological examination showed that it was a metastasis from the intestinal primary tumor. The patient subsequently underwent whole brain radiotherapy for a total dose of 30 Gy in 10 fractions.

Extra-abdominal metastases from gallbladder cancer are very rare; the sites outside the abdomen most frequently affected are the skin, bone and central nervous system. In the literature, only one case of orbital metastasis from gallbladder cancer has been reported, in a patient previously treated by open cholecystectomy. We report the case of a 53-year-old woman who underwent a laparoscopic cholecystectomy for symptomatic gallbladder stones. Postoperative histological examination revealed an unsuspected gallbladder adenocarcinoma. One month later she came to our observation after having developed diplopia and ophthalmic pain due to an orbital metastasis. We decided not to perform a surgical second look because of the already rapid dissemination of the malignant tumor. The few cases of uncommon gallbladder cancer metastases after laparoscopic cholecystectomy described in the literature are discussed, as well as the possible role of laparoscopy in the dissemination and localized seeding of malignant cells.

Pituitary carcinomas are extremely rare. In general, the initial clinical, biochemical, and histological characteristics are of minimal utility in distinguishing benign adenomas from pituitary carcinomas. We describe a 63-year-old woman with a macroprolactinoma, who presented with diplopia and blurred vision. This unusual initial presentation and the subsequent aggressive clinical course, with diffuse local and distant intramedullary metastases, prompted us in retrospect to make a detailed analysis of the therapeutic interventions and histology. In addition, we reviewed all available literature on published cases of malignant prolactinoma and detailed their epidemiological, clinical, and histopathological characteristics. In brief, it is postulated that pituitary carcinomas arise from the transformation of initially large, but benign, adenomas. Unusual and/or atypical clinical manifestations appear to occur more frequently. In vivo, the development of dopamine agonist resistance in invasive macroprolactinoma is indicative of malignancy and should prompt the clinician to perform a biopsy of the tumor. For pituitary tumors that exhibit high mitotic activity, increased Ki-67 and/or p53 immunoreactivity, it may be useful to denote these tumors as 'atypical' prolactinomas to raise the possibility of future malignant development.

LHRH analogs have become a promising modality in prostate cancer therapy as an alternative to surgical castration, and the use of these agents is generally considered to be safe. Since now, only few cases of an apoplexy of previously undiagnosed pituitary adenoma (usually gonadotropinoma) at the beginning of therapy have been described in the medical literature. We present a case of a 74 year old patient who was diagnosed of prostate cancer at the age of 68. There was no evidence of metastatic disease. Radical prostatectomy was performed and LHRH analog gosereline (Zoladex 3.6 mg s.c.) was administered. During the first day after gosereline injection the patient developed headaches that became more severe over the next 3 days. Then the patient experienced nausea and vomiting, double vision and eyelid ptosis. On the 5th day the patient temporarily lost consciousness and was admitted to hospital. Imaging (computerized tomography, magnetic resonance imaging) revealed the presence of a pituitary tumor and hemorrhage within the gland. There was no evidence of pituitary dysfunction in hormonal studies. Neurosurgical intervention was postponed for 5 days after admission. Pathological mass with signs of recent hemorrhage was removed via transsphenoidal route. The tumor had negative immunohistochemical GH, ACTH and PRL staining. Neurological impairment resolved within 9 months after the operation. As a result the patient required adrenal and thyroid replacement. During 6 years of follow-up there was no evidence of prostate cancer recurrence.

A 19-year-old man presented with a rare skull metastasis from atypical pulmonary carcinoid tumor (APCT) manifesting as headache, diplopia, and cough. Head magnetic resonance imaging showed a skull base tumor extending from the posterior clinoid process to the clivus, and calvarial tumors in the right temporal and occipital bones. Chest and abdominal computed tomography showed a round tumor, 4 cm in diameter, in the lower lobe of the right lung and multiple small tumors in the liver. Surgery for the calvarial tumor in the right temporal bone was performed on June 27, 2003. The histological diagnosis was skull metastasis of neuroendocrine tumor. Gamma knife radiosurgery was performed for the residual skull metastases. Partial resection of the right lower lobe was performed for the lung tumor on August 22, 2003. The histological diagnosis was atypical carcinoid tumor. Subsequent adjuvant systematic chemotherapy was performed. The patient died of progression of the tumors in the lung and liver on April 19, 2004. We must consider APCT in the differential diagnosis of pulmonary tumors in adolescents, and perform follow-up observation or treatment, including surgery, if APCT is suspected.

Herein we report a rare case of a pituitary metastasis from a neuroendocrine tumour mimicking an adenoma. Moreover, starting from this unusual case, the relevant literature concerning the diagnosis and management of patients with metastasis at pituitary level is reviewed. A 69-year-old woman was admitted to our Unit for severe headache, diplopia, and critical visual field impairment. MRI showed a large pituitary mass compressing the optic chiasm and infiltrating the cavernous sinus. Trans-sphenoidal biopsy revealed a pituitary metastasis from a neuroendocrine tumour, in line with the multiple liver lesions that were already considered metastases from an ileal primary neuroendocrine tumour. In vitro receptor characterisation of both pituitary and liver tissues by immunohistochemistry showed a heterogeneous somatostatin receptor subtype pattern, with a predominant expression of sst(2) within the pituitary lesion. However, the liver metastasis receptor profile was completely different from the pituitary. Octreotide LAR was administered first, followed by receptor radiometabolic therapy with radiolabelled somatostatin analogues ((90)Y-DOTATOC and (177)Lu-DOTATATE). After 16 months, MRI showed a significant shrinkage of the sellar mass. Moreover, disappearance of diplopia and visual defects, together with a considerable improvement in quality of life were gradually recorded. To our knowledge, this is the first case of combined treatment using "cold" and radiolabelled octreotide in a pituitary metastasis from a neuroendocrine tumour.

Retrobulbar metastases from transitional cell carcinoma of the urinary bladder are very rare. This is a case report of palliative radiotherapy successfully reducing acute clinical symptoms such as proptosis, dysfunction of the eye muscles and diplopia in a 50-year-old male patient with a retrobulbar metastasis from transitional cell carcinoma. Radiotherapy quickly ameliorated the proptosis and dysfunction of the eye muscles without side effects. The patient's quality of life was clearly improved.

We report the first case in the world literature of laryngeal spindle cell carcinoma metastasising to the orbit. A 65-year-old woman was previously treated for T3 N0 Mx laryngeal spindle cell carcinoma, with laryngectomy and post-operative radiotherapy. Five months following this treatment, she developed proptosis, diplopia and reduced right visual acuity, secondary to an enlarging mass within the right orbit. This was biopsied, and subsequent histology confirmed a diagnosis of metastatic spindle cell carcinoma. Subsequent post-mortem examination demonstrated additional pulmonary, hepatic and cardiac metastatic disease, in the absence of any other primary tumour or locoregional disease. The radiological investigation of patients with laryngeal spindle cell carcinoma is discussed and contrasted with that of laryngeal squamous cell carcinoma.

A 55-year-old woman presented with a 1-week history of vision loss in the right eye associated with proptosis and diplopia. Past medical history was significant for high-grade leiomyosarcoma of the uterus status post total abdominal hysterectomy and bilateral salpingo-oophorectomy and postoperative pelvic radiation 18 months prior to presentation. Staging studies at the time of initial diagnosis of uterine leiomyosarcoma showed no evidence for metastatic disease. At presentation, CT and MRI showed a well-circumscribed 3.0 cm x 3.6 cm x 2.4 cm mass centered in the right greater sphenoid wing, extending into the middle cranial fossa and the superior and lateral orbital wall. Biopsy of the orbital mass revealed a poorly differentiated high-grade leiomyosarcoma, consistent with recurrent metastatic disease from the uterus. The patient subsequently underwent radiation treatment followed by a left orbital exenteration 6 months after the orbital biopsy. A left thoracostomy was performed 8 months after the orbital biopsy for a metastatic nodule in the left lower lobe of the lung. The clinicopathologic findings of this rare metastatic orbital lesion are presented.
