Hepatocellular carcinoma treated with transarterial chemoembolization: Evaluation with parametric contrast-enhanced ultrasonography.

Aim: To evaluate the response of hepatocellular carcinoma (HCC) to transarterial chemoembolization (TACE) using a simplified protocol of parametric contrast-enhanced ultrasound (pCEUS).

Methods: Eighteen patients with HCC (18 target tumors, diameter: 2.8-12 cm) were evaluated before, and 20 d after TACE.

Acute suppurative parotitis: a dreadful complication in elderly surgical patients.

Background: Acute suppurative parotitis (ASP) is a severe infection seen particularly in elderly surgical patients. Factors that increase the risk of ASP include post-operative dehydration, debilitating conditions, and immunosuppressed states.

Method: Case report and literature review.

Synchronous primary adenocarcinoma and ancient schwannoma in the colon: an unusual case report.

Gastrointestinal schwannomas are uncommon stromal tumors of the intestinal tract and colon schwannomas are extremely rare. We report a rare case of ascending colon schwannoma with associated synchronous adenocarcinoma of the sigmoid colon. A 68-year-old man presented with a 20-day history of bleeding per rectum.

Borderline clear cell adenofibroma of the ovary associated with ovarian endometriosis: a case report.

Clear cell tumours of the ovary are relatively uncommon. Most of them are clear cell carcinomas. Benign and borderline clear cell tumours are extremely rare and almost always fibromatous.

Atypical polypoid adenomyoma of the uterus. A case report and a review of the literature.

Atypical polypoid adenomyoma (APA) is a rare, benign lesion. The tumor occurs in nulliparous women aged 22-48 years (average 33 years) and it has been suggested as being related to prolonged estrogenic stimulation. We describe a case of a 72-year-old woman who presented at our hospital with persistent, worsening urinary incontinence and pelvic pain.

Quantum dots hold promise for early cancer imaging and detection.

Despite all major breakthroughs in recent years of research concerning the complex events that lead to cancer expression and metastasis, we are not yet able to effectively treat cancer that has spread to vital organs. The various clinical phases originating from cancer diagnosis through treatment and prognosis require a comprehensive understanding of these events, to utilise pre-symptomatic, minimally invasive and targeted cancer management techniques. Current imaging modalities such as ultrasound, computed tomography, magnetic resonance imaging and gamma scintigraphy facilitate the pre-operative study of tumours, but they have been rendered unable to visualise cancer in early stages, due to their intrinsic limitations.

Colon cancer perforation presenting as a strangulating ventral hernia.

Colorectal cancer remains the second leading cause of death from malignant disease. Despite improvements in the treatment modalities offered to patients, more than half of the operated patients die from the disease. The most common presenting symptoms of colonic carcinoma are changes in bowel habits, bleeding, abdominal pain, abdominal mass, stools mixed with mucus or not, weight loss, anorexia, and other characteristics related to metastasis.

Primary cutaneous apocrine carcinoma of sweat glands: a rare case report.

Cutaneous apocrine gland carcinoma, a subtype of sweat gland carcinoma, is a very rare malignancy, and only few cases have been reported in the literature. Many of these carcinomas are indolent and slowly developing, but some are rapidly progressive. The treatment of choice is wide local excision with clear margins, with or without lymph node dissection.

Angiofibroma of the spermatic cord: a case report and a review of the literature.

Introduction: Cellular angiofibroma is a benign vascular neoplasm that typically arises in the paratesticular region in men and is easily confused with inguinal or scrotal hernia.

Case Presentation: We present a case of a cellular angiofibroma arising from the spermatic cord of a 74-year-old Caucasian man. Initially, the lesion was confused with a scrotal hernia, but imaging revealed a subcutaneous, inhomogeneous, but well-circumscribed lesion to the surrounding tissues with rich vasculature.

Soft tissue paraspinal inflammatory malignant fibrous histiocytoma presenting as a lumbar abscess.

The rarest subtype of malignant fibrous histiocytoma (MFH) is the inflammatory type, which due to its peculiar clinical presentation may mimic an infectious process such as an abscess. The rarity of this disease and the unique features of its presentation may mislead the surgeon with consequent catastrophic results for the patient. In this study, a case report of a 65-year-old female patient with a soft-tissue inflammatory MFH presenting as a lumbar abscess and a review of the current literature are presented.

An unusual case of unilateral malignant leydig cell tumour of the testis.

Leydig cell tumour is a benign testicular non-germ cell tumour, and malignant transformation is rare. We report a case of a 35-year-old man who came to our hospital with a painless left testicular mass measuring 1.2 × 1 cm.

Accuracy of modern ultrasonographic techniques in the follow up of patients with superficial bladder carcinoma.

Purpose: The present study was carried out to establish the accuracy of modern ultrasonographic techniques in the follow up of patients with superficial bladder carcinoma and to evaluate the patients tolerability of cystoscopy.

Methods: Thirty-three patients with a history of superficial bladder carcinoma under active surveillance were initially examined using transabdominal ultrasound followed in the same day by cystoscopy.

Results: Fourteen out of the 33 subjects were found to have bladder carcinoma recurrence on cystoscopy.

Primary malignant mixed müillerian tumour of the fallopian tube. Report of a case.

Malignant mixed müllerian tumour of the fallopian tube is an extremely rare lesion and to date only approximately 50 cases have been reported. The tumour is seldom distinguished preoperatively from other more common lesions or ovarian cancer. We report a case of a 60-year-old woman who presented to our hospital with pelvic pain.

Pure Sertoli cell tumor. a case report and review of the literature.

Pure Sertoli cell tumor (SCT) is a rare sex cord tumor and a subtype of Sertoli-Leydig cell tumors according to the WHO Classification. They lack a Leydig cell component and do not contain the immature neoplastic stroma found in the neoplasms of the Sertoli-Leydig cell category. The age of the patients ranges between two and 79 years.

Sarcomatoid carcinoma of the prostate: a case report.

Sarcomatoid carcinoma of the prostate is a rare variant of prostatic cancer, with less than 100 cases reported in the literature up to date. Tumors are most commonly composed of an admixture of both malignant glandular and spindle cell elements. The sarcomatoid component can vary from 5 to 99%.

Adenosquamous carcinoma of the pancreas: a case report.

Adenosquamous carcinoma of the pancreas is a rare variant of pancreatic exocrine carcinoma. We report a case of 70 year old man who came to our hospital with abdominal pain, anorexia and jaundice. Imaging of the abdomen showed a mass in the region of the head of the pancreas.

The impact of diabetes type 2 in the pathogenesis of benign prostatic hyperplasia: a review.

Introduction: Clinical observation of larger prostate glands in men with diabetes mellitus type 2 led some investigators to hypothesize that an association between these two conditions exists. In fact, both diseases are very common in men as they age and seem to be sharing similar epidemiologic features. Several studies examining the above hypothesis were yielded.

Intravascular T-cell lymphoma of the vulva, CD30 positive: a case report.

Primary non-Hodgkin's lymphoma involving the vulva is very rare. It affects predominantly the labia major but it can also present as a clitoral mass or can even be located in the Bartholin's gland. Vulvar lymphoma is an aggressive disease.

Synchronous endometrioid carcinoma of the uterine corpus and ovary. A case report and review of the literature.

Synchronous endometrioid carcinoma of the uterine corpus and ovary is an uncommon but well recognized event. Diagnosis as either a separate independent primary or as a metastatic tumor requires careful consideration of a number of gross and histological features. These features illustrate the criteria helpful in distinguishing independent primaries from metastatic carcinomas which have a different therapeutic implication.

Hepatoid carcinoma of the ovary. A case report and review of the literature.

Hepatoid carcinoma (HCO) is a rare ovarian tumor and is thought to be a different subtype from hepatoid-type yolk sac tumor based on its pathologic features. In contrast to hepatoid yolk sac tumor in which the patients are usually young, patients with HCO are elderly with a peak incidence during the sixth decade of life. None of the patients with HCO have had gonadal dysgenesis or recognizable germ cell components within the tumors.

Malignant adenomyoepithelioma of the breast--case report.

Malignant adenomyoepithelioma (MAME) of the breast is a rare tumor characterized on the basis of histologic, immunohistochemical and ultrastructural features by malignant proliferation of the epithelial and myoepithelial cells. We report a case of an 80-year-old woman with malignant adenomyoepithelioma of the breast, one of the oldest patients described up to today. A primary tumor in the left breast grew within a short period of time.

Combined carcinoid and mixed (composite) glandular - endocrine cell carcinoma of the stomach in atrophic gastritis.

We describe a case of gastric carcinoid and inflammatory fibroid polyp concomitant with a composite tumor of the gastric antrum composed of poorly differentiated adenocarcinoma - endocrine carcinoma with immunohistochemical documentation of endocrine and non endocrine differentiation in a 67-year-old man with atrophic gastritis and intestinal metaplasia. When gastrectomy was carried out, two lymph nodes along the greater curvature harbored metastasis from carcinoid. The same occurrence is reported in several cases in the literature, which suggests that the association of gastric carcinoid to adenocarcinoma could point to the malignant nature of carcinoid.

Glomus tumor of the stomach: a case report.

Glomus tumors are relatively uncommon benign neoplasms, most common in the skin and subcutaneous tissue, but can also occur in the viscera, most often in the stomach. Preoperative diagnosis, when the tumor occurs in the stomach, seems difficult but is important, since glomus tumors of the stomach are essentially benign and amenable to conservative excision, contrary to aggressive gastric neoplasms. We describe the case of a 75-year-old man presented to the emergency department with gastrointestinal bleeding and epigastric pain.

Intracranial haemorrhage possibly related to Tipranavir in an HIV-1 patient with cryptococcal meningitis.

A 55-year-old HIV-infected patient on antiretroviral treatment with Ritonavir-boosted Tipranavir as part of HAART developed intracranial haemorrhage during the acute phase of cryptococcal meningitis. CT scan and MRI confirmed the intracranial haemorrhage. Positive cryptococcal antigen and cultures of both blood and CSF confirmed the diagnosis of meningitis caused by Cryptococcus neoformans.

Study on the efficacy of cefaclor for the treatment of asymptomatic bacteriuria and lower urinary tract infections in pregnant women with a history of hypersensitivity to penicillin.

Purpose: The purpose of this study was to compare the efficacy and safety profile of twice daily versus the conventional three daily intake of cefaclor administrated orally for five to seven days in the treatment of asymptomatic bacteriuria or acute cystitis in pregnant women with a history of hypersensitivity to penicillin.

Methods: Between August 2003 and August 2004, 63 pregnant women with a positive urine culture and a history of suspicion of hypersensitivity to penicillin were randomly divided into two groups. The women in the first group received 500 mg of cefaclor while those in the second group received 750 mg of cefaclor for five to seven days.
