Generalized lymphadenopathy is a rare manifestation of metastatic prostate cancer. Here, we report the case of a 65-year-old patient with supraclavicular, mediastinal, hilar, and retroperitoneal lymphadenopathy and pulmonary infiltration, which suggested the diagnosis of lymphoma. There were no urinary symptoms, and the serum prostate-specific antigen (PSA) was only mildly increased with a normal free PSA. A biopsy of the supraclavicular lymph node was compatible with adenocarcinoma, whose prostatic origin was shown by immunohistochemical staining with PSA. The origin of the primary tumor was confirmed by directed prostate biopsy. We emphasize that a suspicion of prostate cancer in men with adenocarcinoma of undetermined origin is important for an adequate diagnostic and therapeutic approach.

Prostate stem cell antigen (PSCA) and prostate-specific antigen (PSA) are overexpressed in most prostate cancers. PSCA- and PSA-derived, HLA-A2 binding peptides are specific targets for T-cell responses in vitro. A phase I/II trial was performed to demonstrate feasibility, safety and induction of antigen-specific immunity by vaccination with dendritic cells (DC) presenting PSCA and PSA peptides in patients with hormone- and chemotherapy-refractory prostate cancer. Patients received 4 vaccinations with a median of 2.7 x 10(7) peptide-loaded mature DC s.c. in biweekly intervals. Clinical responses were assessed 2 weeks after the 4th vaccination. Immune monitoring was performed by DTH and HLA multimer analysis. Twelve patients completed vaccination without relevant toxicities. Six patients had stable disease after 4 vaccinations. One patient had a complete disappearance of lymphadenopathy despite rising PSA. Four patients with SD and 1 progressor developed a positive DTH after the 4th vaccination. With a median survival of all patients of 13.4 months, DTH-positivity was associated with significantly superior survival (p = 0.003). HLA tetramer analysis detected high frequencies of peptide-specific T cells after 2 vaccinations in 1 patient who was also the sole responder to concomitant hepatitis B vaccination as an indicator of immune competence and survived 27 months after start of vaccination. Vaccination with PSA/PSCA peptide-loaded, autologous DCs may induce cellular responses primarily in immunocompetent patients, which appear to be associated with clinical benefit. Testing of DC-based vaccination is warranted for patients at earlier stages of prostate cancer.

SummaryAn unusual case of malakoplakia of the cervical lymph nodes in a patient with bony metastasis from prostrate cancer is reported. An 80-year-old patient with metastatic prostatic cancer presented with bilateral cervical lymphadenopathy, and a hard cervical mass in the left supraclavicular region. Biopsy of the lymph gland revealed the presence of malakoplakia, with no evidence of metastatic prostatic carcinoma. Though co-existence of malakoplakia and adenocarcinoma within the prostrate gland has been reported before, this case is unique, as it highlights the rare occurrence of malakoplakia involving distant nodes in a patient with bony metastatic prostate cancer. This report reflects the fact that things are not always what they seem in medicine, and not infrequently we come across a different pathology which mimics another.

Carcinoma of the prostate is predominantly a disease of older men. Men younger than 50 years of age account for approximately 1% of all patients diagnosed with prostate cancer. Patients generally present with urinary symptoms and rarely with metastatic disease. Lymphatic spread typically occurs to the obturator and internal iliac nodes. We report a case of an aggressive prostate adenocarcinoma in a 47-year-old white male who presented with nausea, vomiting, and enlarged inguinal lymph nodes for 1 month. A fine needle aspiration biopsy (FNAB) and immunohistochemical stains performed on the FNAB revealed metastatic prostatic adenocarcinoma. The initial clinical presentation of inguinal lymphadenopathy, the age of the patient and the cytologic features made this an unusual case.

Prostate carcinoma is one of the most frecuent cancers in men. Significant numbers of patients have regional lymph node and bone metastases during the course of the disease. Mediastinal lymphadenopathy and cutaneous metastases are uncommon and signify well-advanced disease. We report the case of a patient with prostate cancer who develops mediastinal lymphadenopathy, pulmonary nodules and cutaneous metastases 8 years after the diagnosis.

The metastases of prostate cancer shows the regional lymphatic dissemination, being the cervical lymphatic metastases to infrequent and little reported in Literature. In the present work we contributed a new observation of this organization. We displayed a clinical case with lateral mass cervical left, abdominal pain and diarrheic. When making biopsy of cervical adenopathy reported adenocarcinoma prostate metastases. Colonoscopy with biopsy was made whose results were carcinoma little differentiated infiltrated necrotic center to rectum. The complementary studies demonstrated bilateral aortic adenopathys without injuries in thorax. Within the diagnosis differential of the cervical adenopathys in neck in adult men it must consider the prostate carcinoma, because in an early diagnosis and adapting treatment it can prolong the survive.

Prostate cancer progression is commonly manifested by obstructive uropathy, regional lymphatic metastases and hematogenous metastases to the axial skeleton. Radiotherapy is a mainstay in the palliation of symptomatic metastatic prostate cancer and is most often used for the palliation of painful metastatic bone lesions, resulting in a relief of pain in about 80-90% of patients and a reduction of analgesics. In metastatic disease compromising the integrity of the spinal cord or a nerve root, radiotherapy can be used as an urgent intervention to minimize neurological dysfunction and local progression or as an adjunct to surgical decompression. Local progression is often associated with hematuria, ureteric obstruction and perineal discomfort. Symptoms of metastatic lymphadenopathy like leg edema and back discomfort caused by pelvic or paraaortic metastases are related to the immediate anatomic structures affected. Radiotherapy for localized hormone-refractory prostate cancer has an excellent local control rate; nevertheless, the prognosis is poor, the majority of patients failing with distant metastasis within few years. The role of radiotherapy in hormone-refractory and metastatic prostate cancer, considering the patient's individual situation, are presented and discussed.

Prostate cancer most often metastases to bones and regional lymph nodes. Disseminated metastasis to distant lymph nodes is very rare. We report a case presenting with generalized lymphadenopathy and related left leg edema without any urinary symptoms and finally diagnosed as prostate cancer.

Adenocarcinoma of the prostate (CAP) is a rare diagnosis in men younger than 50 years of age; this age group accounts for less than 0.1% of all patients with prostatic cancer. Left supraclavicular lymphadenopathy (LSCL) as the presenting symptom of metastatic CAP is even rarer. No cases of CAP presenting as LSCL in men younger than 45 years have been reported in the literature. Here we report a 42-year-old male with the uncommon presentation of CAP as LSCL. In adult males with persistent LSCL, even if younger than 45 years, measurement of serum prostate specific antigen is warranted at the time of initial presentation, and the lymph node biopsy should be subsequently stained for prostate specific antigen immunohistochemically. These examinations are crucial to establish a definitive diagnosis of CAP and, in turn, to institute appropriate management and achieve the best possible outcome.

We report a case of Q fever demonstrated on (99m)Tc methylene diphosphonate bone scan and fluorodeoxyglucose (FDG) PET/CT. A 66-year-old man with newly diagnosed, low-grade prostate cancer presented with abdominal and bone pain. Bone scan revealed multiple lesions suspicious for prostate cancer metastases. Because of liver abnormalities on noncontrast CT, an FDG PET/CT was performed and demonstrated FDG-avid sclerotic bone lesions, infiltrative liver disease, and retroperitoneal adenopathy. This appearance, thought unusual for low-grade prostate cancer, prompted extensive clinical evaluation for several months. Liver and iliac bone biopsies showed noncaseating granulomas without neoplasia. Extensive serologic evaluation eventually demonstrated elevated Q fever titers.
