Mucocele of the appendix: case report of a rare disease with changing diagnostic-therapeutic behavior.

Mucinous appendicular neoplasms are a rare and heterogeneous group of tumors, whose treatment may vary based on histologic features and extent. We present a case of low-grade appendiceal mucinous neoplasm mimicking an acute appendicitis scenario. The patient underwent appendectomy along with resection of the caecal fundus.

Waste not, want not: Report of a completely calcified C1-C2 juxtafacet cyst and literature review.

Background: Calcified juxtafacet cysts in the cervical spine are extremely rate. Such symptomatic cysts commonly cause neck pain, radiculopathy, or even myelopathy. MR and CT studies typically document cord/ root compression.

Computed Histological Quantification of Atherosclerotic Plaque Microcalcifications.

Inflammation has a central role in atherosclerotic plaque formation and rupture. Intense macrophage inflammatory activity results in microcalcifications which are strongly associated with plaque vulnerability. Microcalcifications with specific critical size between 5 and 65 μ, located in the fibrous cap producing local mechanical stress on the plaque surface and may directly contribute to plaque rupture.

Rapid malignant progression of an intraparenchymal choroid plexus papillomas.

Background: Choroid plexus tumors (CPTs) are rare neoplasms accounting for only 0.3-0.6% of all brain tumors in adults and 2-5% in children.

Biliary squamous cell carcinoma.

Squamous cell carcinoma of the liver, bile ducts and gallbladder is extremely rare. We report a case of squamous cell carcinoma of the common bile duct manifesting atypically without jaundice, despite its large size and proximal bile duct dilation. A review of the literature concerning all other squamous carcinoma of the biliary tract is presented including 3 other bile duct cancers, 17 intrahepatic and 30 gallbladder cancers.

Simultaneous occurrence of adenoma, focal nodular hyperplasia, and hemangioma of the liver: are they derived from a common origin?

The association between hepatic hemangioma (HH) and focal nodular hyperplasia (FNH) or the association between FNH and hepatic adenoma (HA) has been reported. The authors report a case in which FNH, HH, and HA simultaneously appear in the liver. A 25-year-old woman was admitted to the Department of Surgery of the University of Catania (Italy), after presenting pain in the right hypocondrium.

Colorectal endometriosis: aggressive surgical management and practical considerations in a patient with advanced disease.

The aim of this study was to evaluate the results of bowel resection in a patient with obstructive colorectal endometriosis. The presentation will acquaint the physician with the signs and symptoms, evaluation, and surgical treatment of colorectal endometriosis. We emphasize that our findings strongly support an aggressive surgical approach with resection for all visible cases of colorectal endometriosis in women with advanced disease.

Brain metastasis: first sign of colorectal carcinoma.

The purpose of this study was to describe the detection of a brain metastasis as the first sign of colorectal carcinoma, without any liver and/or lung involvement. This finding demonstrates primarily the need for regular central nervous system investigation in diagnosing colorectal cancer and secondly that further, more thorough research into the biomolecular events involved in metastases from colorectal cancer is warranted.
