Pseudohyperparathyroidism was diagnosed in a mature stallion presented for anorexia, weight loss,
pollakiuria
and constipation. Laboratory findings included hypercalcemia, hypophosphatemia, anemia and isosthenuria. Thoracocentesis indicated an exfoliating squamous cell carcinoma. At necropsy, a squamous cell carcinoma of the stomach with
metastases
to the abdominal and thoracic cavities was diagnosed. No osseous
metastases
were found. No gross or microscopic renal lesions were noted. Bone tissue showed arrested resorption, and the parathyroid gland was atrophic.

A 63-year-old man was admitted with the complaints of macrohematuria, sense of residual urine and
urinary frequency
. Physical examination revealed an enlarged hard prostate and left scrotal mass. The pathological diagnosis of the needle biopsy specimen of the prostate showed undifferentiated adenocarcinoma. The patient underwent bilateral orchiectomy for hormone therapy of prostatic carcinoma and treatment of suspected left testicular tumor. The histology of testicular tumor revealed metastasis from carcinoma of the prostate.
Metastasis
of the testis from prostatic carcinoma is rare in spite of the high incidence of the primary tumor. Clinical findings on testicular metastasis from carcinoma of the prostate obtained in 62 cases reported in available literature are reviewed and discussed in detail.

Clinical study of HCFU for head and neck cancer was performed HCFU at a daily dose of 600 to 900 mg. Was orally administered to 30 patients, including 5 patients with
metastases
. The primary sites of cancer were: larynx 9 cases, mesopharynx 6 cases, hypopharynx 5 cases, maxilla 5 cases, nasopharynx 3 cases, parotid gland and floor of the mouth one each. All of them were squamous cell carcinoma except a case presenting parotid lesion caused by adenocarcinoma. In 7 cases receiving the single therapy of HCFU for one month, a positive response was presented in one out of 7. Twenty-three cases treated HCFU in combination with radiation, 11 showed complete response (CR: over 90% decrease of tumor size), 6 showed partial response (PR: over 50% decrease), 3 showed minor response (MR: over 25% decrease), and 3 were diagnosed as no change (NC). Positive responses evaluated as PR or above obtained at the mean cumulative dose of 25.7 Gy and HCFU 15972 mg. Four cases receiving HCFU in adjuvant chemotherapy were studied only for clinical toxicity. Clinical toxicities of HCFU in 30 patients were presented in transient
pollakiuria
(7 cases), neurotoxic effect (2), eruption and diarrhea (one each). Symptoms similar to anemia and unconsciousness caused by the intake of alcohol were found in 6 patients. Although positive effect of HCFU was observed only in one case being administered singly, it presented better results in more cases when administered in combination with radiation. The combination therapy also made the lesions respond faster than by radiation therapy only. Intake of any alcohol is not advisable.

Carcinomas with micropapillary features have been described in the breast, urinary bladder, lung, and ovary. They are characterized by the presence of micropapillary tufts in clear spaces. Unequivocal vascular invasion is usually present at the periphery of the tumor. Consequently, these tumors have a high propensity for lymph node
metastases
and high-stage disease. The metastatic carcinoma can consist exclusively of the micropapillary component, which may elicit an erroneous diagnosis if located in the bladder or lung, as in the patient presented herein. We present a case of a 59-year-old woman with a history of bilateral breast carcinoma status post-bilateral mastectomy, chemotherapy, and tamoxifen therapy. She presented with
urinary frequency
, and a pelvic mass was noted. A biopsy of the endometrium revealed a poorly differentiated carcinoma. Urinary bladder biopsies showed a carcinoma with micropapillary features diagnosed as micropapillary transitional cell carcinoma. She presented to M.D. Anderson Cancer Center (Houston, TX) for further treatment recommendations. The urinary bladder and endometrial biopsies both contained carcinomas with micropapillary features. The mastectomy specimen showed an invasive ductal carcinoma with a significant micropapillary component. The tumor cells from the breast, endometrium, and urinary bladder were positive for cytokeratin (CK) 7 and estrogen receptor and negative for CK20. In view of the morphologic and immunohistochemical profile, the carcinoma in the endometrium and urinary bladder were interpreted as metastatic lesions from the breast primary. Carcinomas with a micropapillary component are morphologically identical in the breast, urinary bladder, and lung. However, micropapillary serous carcinoma has a different appearance more akin to borderline tumors of the ovary. Immunohistochemical stains are useful in distinguishing these lesions in that thyroid transcription factor-1 positivity suggests a lung primary, CK7 and estrogen receptor suggest a breast primary, and both CK7 and CK20 positivity suggest a urinary bladder primary. It is important to exclude metastatic carcinomas with micropapillary features before making a definite diagnosis of a primary tumor. Carcinomas with micropapillary features have a propensity for lymph node
metastases
and advanced stage disease. This article discusses the differential diagnosis of carcinomas with micropapillary features in different organs.

We report a case of signet-ring cell carcinoma of the urinary bladder. A 48-year-old female was hospitalized because of general fatigue,
pollakiuria
and residual sensation. Renal ultrasonography disclosed bilateral hydronephrosis. The serum level of cretinine was 3.1 mg/dl, and we diagnosed the patient with post-renal failure. Cystoscopic examinations revealed non-papillary sessile tumors in the trigone. Histopathological findings of the biopsy specimen demonstrated signet-ring cell carcinoma. There was no evidence indicating bladder metastasis from the cancer in other organs. The patient died of cachexia 5 months after the diagnosis. She was autopsied, and the diagnosis of signet-ring cell carcinoma of the urinary bladder with
metastases
in various organs was confirmed. This disease is extremely rare and has a poor prognosis. We review the previous cases reported in the literature.

Breast cancer is the most prevalent malignant disease among women, with the exception of non-melanoma skin cancers. Malignant breast tumours metastasise to lungs, bone, liver, lymph nodes and skin, but the literature also reports few cases of unusual
metastases
such as to the bladder. We present the case of a 57-year-old woman affected by lobular invasive breast cancer and complaining of high
urinary frequency
with nicturia. To date this is the seventh reported case of isolated metastatis of breast carcinoma to the bladder.

We report a case of marginally resectable gastrointestinal stromal tumor (GIST) in the pelvis treated with neoadjuvant intent before subsequent successful surgical resection. A 46-year old man presented with
urinary frequency
and rectal discomfort with tenesmus. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a 12 cm diameter mass between the bladder and rectum and the margin of the tumor and prostate was unclear. No
metastases
were evident. Trans-rectal needle core biopsy confirmed c-kit positive GIST. Because of the locally advanced nature of the tumor,immediate surgical resection would have required total pelvic exenteration with eternal colostomy and urinary diversion. Therefore,the patient was treated with imatinib mesylate 400 mg daily in anticipation of adequate tumor size reduction to enable a more simplified surgical approach. After 3 months of imatinib therapy,MRI demonstrated a reduction in tumor size of 60%. Consequently,a complete surgical resection including the bladder,prostate and part of the sigmoid colon with temporary ileostomy and ileal conduit was performed. Pathological findings of the resected specimen showed widespread degeneration with cystic changes,necrosis, and hypocellularlity,as well as nodules of residual viable c-kit positive tumor cells. The patient has been treated with imatinib mesylate for 39 months following the operation without tumor recurrence.

An 8-year-old castrated male hound mix was referred to the Purdue University Veterinary Teaching Hospital for severe lameness,
pollakiuria
, and dyschezia. On presentation, the dog was nonweight bearing on the right rear limb and the right carpus was diffusely swollen. Synovial fluid analysis from the right carpus revealed a population of epithelial cells displaying marked anisocytosis, anisokaryosis, multinucleation, and prominent, variably sized nucleoli. A metastatic carcinoma with presumed prostatic or urothelial origin was diagnosed based on cytomorphology. Subsequent cytologic evaluation of peripheral lymph nodes revealed the presence of a similar neoplastic population. The dog was euthanized and synovial fluid from both stifle joints, as well as impression smears of the prostate gland, were collected. Carcinoma cells were identified in each stifle joint and in the prostate gland. Immunocytochemistry was performed on synovial fluid smears from 2 of the joints (right stifle and right carpus) and on impression smears of the prostate gland. The neoplastic population in the joints and prostate gland showed strong immunoreactivity to uroplakin III, a urothelial marker, indicating metastasis of a transitional cell carcinoma to multiple joints. In addition, evidence for epithelial to mesenchymal transition was identified using cytokeratin, an epithelial marker, and vimentin, a mesenchymal marker. A necropsy was performed and histopathology confirmed the presence of metastatic transitional cell carcinoma in various tissues. This case illustrates the importance of considering
metastatic disease
when a patient is presented with severe lameness and joint pain, and the clinical utility of synovial fluid cytology for diagnosis of metastasis in these cases.

While the gastric involvement of pancreatic cancer is occasionally observed as the result of direct invasion, hematogenous gastric metastasis is rare. A 72-year-old Japanese male presented with general fatigue,
pollakiuria
, and thirst. Computed tomography revealed a 4.6-cm solid mass in the pancreatic tail and a 4.2-cm multilocular cystic mass in the pancreatic head with multiple liver and lymphatic metastasis. Notably, two solid masses were detected in the gastric wall of the upper body and the antrum; both were separated from the primary pancreatic cancer and seemed to be located in the submucosal layer. Esophagogastroduodenoscopy revealed a submucosal tumor with a normal mucosa in the posterior wall of the upper body of the stomach, suggesting the gastric hematogenous metastasis of pancreatic cancer. The suspected diagnosis was unresectable pancreatic cancer with multiple
metastases
that was concomitant with the intraductal papillary mucinous neoplasm of the pancreas.

The diagnosis of a tumor-to-tumor metastasis in the central nervous system most commonly involves metastasis to a meningioma. These combined lesions are often radiographically unsuspected and mimic a meningioma. Most commonly, the source of
metastatic disease
are carcinomas from the lung and breast. To our knowledge, fewer than a half dozen cases of metastatic prostatic adenocarcinoma to a meningioma have been documented in the literature. This report documents a 67-year-old man who presented with worsening confusion and altered mental status, accompanied by symptoms of increased
urinary frequency
, incontinence, and difficulty urinating. Imaging revealed a mass at the base of the bladder and an intracranial lesion, surrounded by edema, which was initially suspicious for intracranial metastasis of prostate cancer. Due to worsening neurological symptoms, the patient underwent craniotomy to remove the intracranial mass. The mass was comprised of a meningothelial meningioma, World Health Organization Grade I, accompanied by atypical epithelioid cells which demonstrated immunoreactivity to prostate specific antigen, chromogranin and neuron specific enolase antibodies, consistent with a metastatic prostatic adenocarcinoma with neuroendocrine differentiation. The patient suffered severe neurological complications post-operatively, developed multiple
metastases
and expired 12months later. The report reviews current theories as to why meningiomas are the most common host tumor for tumor-to-tumor
metastases
in the brain and reviews the literature on previously reported cases involving metastatic prostatic adenocarcinoma.
