Oculoectodermal syndrome: Report of a new case with a broad clinical spectrum

2014

Oculoectodermal syndrome (OMIM 600268) is rare and characterized by aplasia cutis congenita, epibulbar dermoids, and other abnormalities. We report herein on a newly recognized patient with oculoectodermal syndrome, which is the 19th reported patient with OES. The boy aged six years demonstrated a broad clinical spectrum of this condition, including aplasia cutis congenita, epibulbar dermoids, hyperkeratotic papule, mildly enlarged cisterna magna, and an enlarged fluid space in the quadrigeminal cistern, suggesting a cyst. He also manifested anomalies not reported associated with this disorder, including systematized epidermal nevus following Blaschko's lines, hypopigmented skin lesions, an…

Lipomatous Metaplasia. Two Chronic Infarcts in the Same Patient Detected by Cardiac Magnetic Resonance

Acid and gastric metaplasia in the duodenum.

1994

Duodenal and antral mucosal biopsy specimens were obtained from 139 patients with dyspeptic complaints to study the prevalence and extent of gastric metaplasia in the duodenal bulb in relation to Helicobacter pylori (H pylori) infection and duodenal ulcer disease. On logistic regression, the presence and extent of gastric metaplasia was not significantly associated with H pylori infection. The prevalence of gastric metaplasia, however, was found to be higher in patients with current or past evidence of duodenal ulcer disease in comparison with subjects with functional dyspepsia (p = 0.01). A follow up study on 22 patients before and at least one year after eradication of H pylori showed tha…

Breast and chest wall metastatic seeding of adenocarcinoma of the colon with bone metaplasia: immunohistochemical study and differential diagnosis

Immunohistochemical/histochemical double staining method in the study of the columnar metaplasia of the oesophagus

2014

Intestinal metaplasia in Barrett’s oesophagus (BO) represents an important risk factor for oesophageal adenocarcinoma. Instead, few and controversial data are reported about the progression risk of columnar-lined oesophagus without intestinal metaplasia (CLO), posing an issue about its clinical management. The aim was to evaluate if some immunophenotypic changes were present in CLO independently of the presence of the goblet cells. We studied a series of oesophageal biopsies from patients with endoscopic finding of columnar metaplasia, by performing some immunohistochemical stainings (CK7, p53, AuroraA) combined with histochemistry (Alcian-blue and Alcian/PAS), with the aim of simultaneousl…

Tumor Control in a Model of Bone Marrow Transplantation and Acute Liver-Infiltrating B-Cell Lymphoma: an Unpredicted Novel Function of Cytomegalovirus

2002

ABSTRACTTumor relapse and cytomegalovirus (CMV) infection are major concerns in the therapy of hematopoietic malignancies by bone marrow transplantation (BMT). Little attention so far has been given to a possible pathogenetic interplay between CMV and lymphomas. CMV inhibits stem cell engraftment and hematopoietic reconstitution. Thus, by causing maintenance of bone marrow aplasia and immunodeficiency, CMV could promote tumor relapse. Alternatively, CMV could aid tumor remission. One might think of cytopathogenic infection of tumor cells, induction of apoptosis or inhibitory cytokines, interference with tumor cell extravasation or tumor vascularization, or bystander stimulation of an antitu…

Imaging in Prune Belly Syndrome and Other Syndromes Affecting the Urogenital Tract

2018

The absence of the abdominal musculature, urinary tract dilatation, and bilateral undescended testis is known as prune belly syndrome (PBS) (Eagle and Barrett 1950; Greskovich and Nyberg 1988; Williams 1982). The classical syndrome is also known as triad syndrome, Eagle-Barrett syndrome, or abdominal muscular deficiency syndrome. There is a broad spectrum of malformations with severe dilatation of the urinary tract as a consequence of aplasia of the musculature. The pathogenetic mechanism is different from that of dilatation as a consequence of supra- or infravesical obstruction. Some patients with prune belly syndrome have a real obstruction, such as urethral aplasia with oligohydramnios s…

Conversely, their presence in the oral mucosa is rather uncommon, with approximately 4% of the cases occurring in the oral cavity. In such cases, th…

Metastatic seeding of colon adenocarcinoma manifesting as synchronous breast and chest wall localization: report of a case.

2011

Colon carcinoma rarely metastasizes to the breast and it is usually associated with a poor prognosis. Even rarer is metastatic seeding of colon cancer cells in an intramammary location after surgery. Including a primary breast malignancy in the differential diagnosis of such cases is mandatory. We report a rare case of double seeding implantation of colon adenocarcinoma inside the breast parenchyma and intercostal muscles 6 years after resection of a pulmonary metastasis from colon adenocarcinoma. The metastasis was revealed by the presence of bone metaplasia in the intercostal muscles. We discuss how negative immunostaining for estrogen receptors, progesterone receptors, and HER-2, along w…

An unusual case of rudimentary parotid gland with distended Stensen duct

2010

Congenital absence or rudiment major salivary glands, especially of the parotid glands, are a rare entity. Aplasia of parotid glands has been described alone or in association with abnormalities of other salivary glands, first branchial arch developmental disturbances and other congenital anomalies such as lacrimoauriculodentodigital syndrome, mandibulofacial dysostosis and ectodermal dysplasia. Absence is most commonly unilateral, and may be associated with accessory or rudimentary glandular tissue. There are several reported cases of isolated patulous Stensen’s duct causing air insufflations in the glands and recurrent parotid gland enlargement. However, in the literature there is no repo…
