RESUMO
A 79-year-old man with vulvar apocrine adenocarcinoma and right inguinal lymph node metastasis underwent wide excision and free skin graft reconstruction of the primary lesion and right inguinal lymphadenectomy. However, left inguinal lymph node metastasis was noted after 11 months, and left inguinal lymphadenectomy was performed. Twelve days postoperatively, the patient developed left inguinal lymphocele. The lymphocele was drained percutaneously and compressed, but lymph secretion persisted and lymphocele skin necrosis was observed. Therefore, debridement and vacuum-assisted closure (VAC) therapy were performed in cooperation with the department of plastic surgery. Subsequently, lymph secretion declined and eventually stopped. The lymphocele scar was reconstructed with a free skin graft, and after further observation for 8 months, right lymph node swelling was noted. Nevertheless, on the left inguinal site, neither lymphocele recurrence nor inguinal lymph node metastasis was observed. In conclusion, VAC therapy might be beneficial in the treatment of postoperative inguinal lymphocele after lymphadenectomy.

An 84-year-old man was referred to our hospital with swollen right cervical lymph nodes. Computed tomography showed right supraclavicular and mediastinal lymph node enlargement, and fluorodeoxyglucose positronemissiontomography showed multiple areas of abnormally increased radioactivity inthe right supraclavicular and mediastinal lymph nodes, right ninth rib, and left fifth and seventh ribs. Biopsy of the right supraclavicular lymph node revealed metastatic adenocarcinoma with partial immunohistochemical staining for prostate specific antigen (PSA). Serum PSA levels were not elevated (2.01 ng/ml). An 8-core transrectal prostatic biopsy was negative. Thus, we could not determine the primary site of the adenocarcinoma. The patient was diagnosed with carcinoma of an unknown primary site and followed without chemotherapy. Four years later, he was referred to our hospital due to right hydronephrosis. Serum PSA level was 31. 1 ng/ml. The tumor was not palpable by rectal examination. A 12-core transrectal prostatic biopsy revealed a poorly differentiated adenocarcinoma. Computed tomography revealed metastases in the left axilla, para-aortic, and pelvic lymph nodes as well as in the lung. We diagnosed the patient with prostate cancer, and combined androgen blockade (CAB) was administered. Metastases in the lymph nodes, lung, and bone were reduced on imaging after 1 month of therapy. Therefore, a definitive diagnosis of prostate cancer T1cN1M1c was made. Dutasteride had been administered as a benign prostate hyperplasia treatment 2 years before his first visit, which may have made the definitive diagnosis of prostate cancer difficult. In contrast, dutasteride may have delayed the progressionof prostate cancer inthis patient.

Seminal vesicle cyst is a rare disease and is often asymptomatic. We present a case of huge seminal vesicle cyst connected to the abdominal wall and observed as a subcutaneous abscess. An 89-year-old man presented with asymptomatic spontaneous rupture of the left lower abdominal subcutaneous abscess. Computed tomography (CT) showed a relatively low intensity cystic mass located in the Retzius' space just below the abscess, surrounding the right bladder wall laterally and connecting to the right seminal vesicle posteriorly. Biopsy of the skin around the subcutaneous abscess and aspiration biopsy of the pelvic cystic fluid showed no evidence of malignancy. We diagnosed the lesion as a seminal vesicle cyst with bacterial infection. The patient was treated with antibiotics and there has been no relapse.

We described a 63-year-old man who was diagnosed with clinical T1c prostate cancer, with a Gleason score of 6 (3ï¼3), and a preoperative prostate-specific antigen (PSA) level of 5. 27 ng/ml. Radical prostatectomy(RP) was performed and final pathologyshowed Gleason score 3ï¼4, pT2c with negative surgical margin. In spite of suggested surgical radicality, PSA was 3.32, 4.78, 5.93 ng/ml, at 1, 2, and 3 months after RP, respectively. However, radiological investigation revealed no metastasis. Because of this clinical discrepancy, we checked the PSA-α1-antichemotrypsin level and found it to be â¦0.1 ng/ml. From these results, false PSA elevation caused byinterference of positive heterophilic antibodies was suggested and demonstrated byseveral immunoassays.

Cholesterol crystal embolization (CCE) is a cardiovascular disorder with poor prognosis, causing multiple organ failure. The primary pathological condition of the disease is embolization of cholesterol crystals in peripheral vessels. We report a case of CCE following urinary diversion. The patient is a 82-year-old male with history of hypertention, pneumonectasia, interstitial pneumonia, and heavy smoking. He was afflicted with advanced bladder cancer. He underwent urinary diversion, and had been scheduled for palliative radiotherapy. The next day, he developed thromboembolism of the left lower leg as acomplication of urinary diversion. Thrombectomy by endovascular catheter procedure was performed immediately, and anticoagulant therapy was started. The day after the thrombectomy, his lower legs showed livedo reticularis and toes showed cyanosis (blue toe). Since the laboratory data showed acute deterioration in renal function, hemodialysis was initiated. Three days after the thrombectomy he died of multiple organ failure. At autopsy, diffuse atherosclerosis of the aorta was observed, and cholesterol crystalemboli were found in the skin of the left foot ; and, the diagnosis of CCE was confirmed. This case suggests that tissue examinations for early diagnosis and stopping anticoagulant therapy are preferred when CCE is suspected.
