1/326. Tc-99m HDP uptake in cardiac amyloidosis.amyloidosis is characterized by the soft-tissue deposition of amyloid protein. It may occur as a primary disorder but more often is seen as a manifestation of chronic illness. Scattered reports of the affinity of amyloid for bone scanning agents have appeared over many years. Isolated cardiac uptake of Tc-99m HDP is described in a patient with biopsy-proved cardiac amyloidosis on a background of tuberculosis, prostate cancer, and coronary artery disease.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
2/326. A case of prostatic cancer metastasizing to the orbit.PURPOSE: We report on a case of prostatic cancer with multiple bone metastases, including right orbital involvement. methods/RESULTS: Hormonal treatment and local irradiation to the right orbit were performed. Subjective symptoms with exophthalmos and pain disappeared. CONCLUSIONS: We report on a case of prostatic cancer metastasizing to the right orbital bone.- - - - - - - - - - ranking = 2keywords = bone (Clic here for more details about this article) |
3/326. Gingival metastasis from a prostate adenocarcinoma: report of a case.Prostate cancer is the cause of 10% of cancer-related deaths in males in the united states. Metastases are found late in the course of the disease. Metastatic tumors of the oral cavity are rare, representing about 1% of oral tumors and affect jaws much more frequently than soft tissues. Metastatic prostate cancer tends to involve the bones of the axial skeleton. In a recent review, 22 cases of metastases to the jawbones from prostate cancer were found in 390 cases. On the other hand, only 1 case of a metastasis to the oral soft tissues was reported. The authors describe the second case of oral soft tissue metastasis from a prostate cancer. The metastatic lesion was located in the gingiva. Clinicians should be aware of oral soft tissue metastases since they can be the first sign of a not yet diagnosed malignant tumor and they can be very easily confused with several different benign lesions.- - - - - - - - - - ranking = 2keywords = bone (Clic here for more details about this article) |
4/326. Computed tomography guidance in bone marrow aspiration for diagnosis of marrow necrosis and metastasis.bone marrow necrosis is most frequently diagnosed at postmortem examination. Antemortem diagnosis is still uncommon. We illustrate four cases where initial bedside attempts at needle aspiration and biopsy of primary and metastatic tumor tissue from the sternum were complicated by inadequate specimen retrieval secondary to marrow necrosis and/or tissue destruction by tumor. In these cases, CT guidance was useful in the precise localization of the bulk of the tissue mass and consequently the successful retrieval of adequate diagnostic specimens. We demonstrate CT guidance as an excellent and convenient alternative in circumstances where adequate marrow aspirations and biopsies are difficult and complicated.- - - - - - - - - - ranking = 4keywords = bone (Clic here for more details about this article) |
5/326. Mucin-producing carcinoma of the prostate: review of 88 cases.OBJECTIVES: To report on a case of mucinous carcinoma of the prostate and discuss the clinical and histopathologic features of the mucin-producing carcinoma of the prostate from a review of published reports. methods: Our case and 87 other previously reported cases were evaluated clinically and histologically. RESULTS: We encountered a case of mucinous carcinoma of the prostate, Stage C, which was treated by radical prostatectomy. After reviewing it and the 87 other cases, we believe that these cases of mucin-producing carcinomas can be divided into three groups: 60 cases of mucinous carcinoma, 17 cases of primary signet-ring cell carcinoma, and 11 cases of mucinous carcinoma with signet-ring cells. Mucinous carcinoma is a variant of high-grade adenocarcinoma of the prostate, wherein there is a 77.8% rate of prostate-specific antigen elevation and a similar rate (77.8%) of response to endocrine therapy. Fifty percent of patients survived 3 years and 25%, 5 years. In contrast, primary signet-ring cell carcinoma conveys one of the worst prognoses among patients with prostate cancer. There are no reliable tumor markers, and there was no response to endocrine therapy. patients with primary signet-ring cell carcinoma had a 27.3% 3-year survival rate; none survived to 5 years. The clinical features of mucinous carcinoma with signet-ring cells are very similar to primary signet-ring cell carcinoma; again, there was no response to endocrine therapy and the 3-year survival rate was 16.7%. CONCLUSIONS: Although it has been suggested that mucinous carcinoma is a variant of high-grade adenocarcinoma of the prostate, signet-ring cell carcinoma and mucinous carcinoma with signet-ring cells are other variants of carcinoma that develop in the prostate, and their prognoses are very poor.- - - - - - - - - - ranking = 3.8963168856613keywords = endocrine (Clic here for more details about this article) |
6/326. Multiple pulmonary metastasis of prostatic carcinoma with little or no bone or lymph node metastasis. Report of two cases and review of the literature.We describe 2 cases of prostatic carcinoma with pulmonary metastasis. In the first case there was no lymph node or bone metastasis, and in the second case there was only one bony metastatic lesion. Presentation, etiology and management are discussed.- - - - - - - - - - ranking = 5keywords = bone (Clic here for more details about this article) |
7/326. Laparoscopic treatment of parapubic postprostatectomy hernia.We are reporting the case of a parapubic hernia that occurred after radical prostatectomy. This kind of the hernia is caused by the weakening of the attachments of rectus muscles to the pubic bone. Because of its location, it may be misdiagnosed as a far more common direct inguinal hernia. A laparoscopic approach made it possible to precisely diagnose and repair the defect in the abdominal wall.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
8/326. disseminated intravascular coagulation in a patient treated with strontium-89 for metastatic carcinoma of the prostate.strontium-89 is effective in the palliation of bone pain caused by skeletal metastases. Its primary side effect is mild thrombocytopenia that typically recovers in 3 or 4 months. Subclinical disseminated intravascular coagulation is reported to be present in approximately 10% to 20% of patients with advanced prostate cancer. These patients may be at increased risk for severe marrow depression after radionuclide therapy for bone pain palliation. This report describes a patient with painful bony metastases resulting from prostate carcinoma. He had a normal platelet count and no clinical evidence of a coagulation disorder at the time of strontium-89 therapy, and a severe disseminated intravascular coagulation developed and lead to death after treatment. A normal platelet count before strontium-89 therapy does not preclude subsequent disseminated intravascular coagulation, and we support the Society of nuclear medicine's bone pain treatment procedure guideline that patients referred for bone palliation should be screened for disseminated intravascular coagulation before therapy.- - - - - - - - - - ranking = 4keywords = bone (Clic here for more details about this article) |
9/326. Sub-super bone scan caused by bone marrow involvement of prostate cancer.A 67-year-old man presented with malaise and marked anemia. A diagnostic workup revealed severe pancytopenia on a complete blood count and diffuse sclerotic change in the axial skeleton on a plain abdominal radiograph. Bone metastases being suspected from these findings, bone scintigraphy was performed. The bone scan demonstrated uniformly increased skeletal activity with faint soft-tissue activity. The findings of the bone scan, however, appeared atypical of the super scan caused by diffuse bone metastases, without any decrease in radioactivities of the appendicular skeleton and kidneys. bone marrow scintigraphy with In-111 chloride demonstrated central marrow failure and peripheral expansion, which indicated the possibility of myelophthisis. The patient underwent bone marrow biopsy, which revealed replacement of the bone marrow by metastatic adenocarcinoma. Further examinations detected the primary lesion in the prostate. In this case, the findings of the bone scan were insufficient for the super scan, and might be categorized as a sub-super scan. It would be important to recognize this incomplete form of super scan as a rare scintigraphic pattern of diffuse bone marrow metastases.- - - - - - - - - - ranking = 16keywords = bone (Clic here for more details about this article) |
10/326. Efficacy of total androgen blockade in metastatic prostatic carcinoma with transient hypogonadotropic hypogonadism: a case report.A patient affected by metastatic prostatic carcinoma and hypogonadotropic hypogonadism (HH) was treated with flutamide 750 mg/day plus an LH-RH analog. After confirmation of basal castration during treatment, he continued with antiandrogens alone. Following the normalization of gonadic function and subjective mild bone flare-up, the patient resumed the initial treatment and obtained a partial response. When flutamide was interrupted because of liver toxicity, the patient showed progressive disease in the bone, which was unresponsive to both flutamide resumption and salvage hormone therapy (bicalutamide). The patient is currently receiving chemotherapy with VP16 and estramustine phosphate and is showing both serologic (PSA) and symptomatic response. The interest of this case lies in the incidental detection of HH during therapy and in the responsiveness to treatment.- - - - - - - - - - ranking = 2keywords = bone (Clic here for more details about this article) |
