mutation syndromes, though these are now better referred to as Proteus-like, or separate disorders (e.g. SOLAMEN, CLOVES).1 Epidemiology: Proteus syndrome is exceedingly rare. Few more than 200 cases have ever been described in literature, with an estimated incidence of less than 1 per 1,000,000 live births, though the disease may be underdiagnosed if not severe (i.e. the somatic mutation occurs later in development ), or mistaken for other hamartoma syndromes.3,4 Diagnostic tests: A preliminary clinical diagnosis can be made based on the appearance of clinical symptoms. The most definitive diagnostic test is to sequence the 14q32.33 AKT1 gene in an affected tissue region for a c.49G>A, p.Glu17Lys mutation (a point mutation of guanine to adenine, resulting in glutamate instead of lysine after translation).1 Testing of blood or unaffected tissue is not an effective method in most cases, and there are no known circulating biomarkers.5 Symptoms and physical signs: The key finding in the disease is overgrowth of normal tissues with hamartoma formation that is characteristically mosaic, sporadic, and progressive. The most recent diagnostic criteria by Cohen et al. includes a number of specific benign tumors and malformations common with the condition. Some key specific criteria include cerebriform connective tissue nevi, hemihyperplasia with bone deformity , and dysregulated adipose and vascular tissue (Figure 3). The tumors caused by the disease are largely benign, and…

don’t spread to other parts of the body. They grow slowly or they can stop growing and shrink. They typically don’t need to be removed, and can expand and push against tissues that are close but do not penetrate, destroy, or replace the nearby tissue. If it grows 3 centimeters or less in diameter, it’s known as a nodule. A nodule that forms in the lung is called a pulmonary nodule. If it grows past 3 centimeters, its typically called a mass. There are two different kinds of benign lung tumors…

Tuberous sclerosis (TSC) is complex, multifaceted genetic disorder that results in production of hamartomatous lesions that may affect virtually every organ system of the body. The best-known cutaneous manifestation, presented in this vignette, of TSC is adenoma sebaceum. This lesion is an angiofibroma (cutaneous hamartoma) and the name is a misnomer, as it is not related to excessive sebum or acne. Flat, reddish, macular lesions develop first, which can be initially mistaken for freckles. Some…

However it has been shown that some mutations in the PTEN can result in various clinical features such as the PTEN Hamartoma Tumor Syndrome (PHTS) and the Autism spectrum disorders (ASD). The syndromes that falls into the PHTS categories includes, Bannayan-Riley-Ruvalcaba syndrome (BRRS), Cowden syndrome (CS), and PTEN-Related Proteus syndrome (PS). BRRS is a genetic condition resulted by a deletion or mutation of the PTEN gene. However more than 60% of all cases of BBRS are due to the…

Some neurological defects like hydrocephaly, lissencephaly, partial agenesis of the corpus callosum are also reported with the Proteus syndrome. 112 It may cause paraspinal hamartoma. 110 Protuberance of the skull, 113 structural and functional asymmetry of the central nervous system, 114 hydrocephalus and mental retardation are also some features of proteus syndrome. 113 Epilepsy and ohtahara syndrome is diagnosed in children affected by Proteus syndrome associated with infantile spasms,…

important information. Where in a certain situation, a person processes every aspect of a given stimuli without controlling it. Some psychiatrist say that combined with a high IQ can make a person a creative genius. This applies to Michael; he has a very high IQ allowing him to be successful at certain task. I feel like that was one of the reasons he chose to be a structural engineer. Where he could image every detail of a building like the framework, floor plan, the walls, the window, and all…

operation as the tight medial structures even in severe clubfeet typically respond to serial casting [30]. Another indication for operation in the clubfoot correction is recurrent clubfoot deformities following initial conservative treatment alone. Another indication for surgery in clubfoot treatment is for those feet that have been initially treated with extensive soft tissue release operations and have residual deformities following an incomplete correction, an overcorrection, or from…

common than FGPs in regions where Helicobacter pylori infection is more prevalent. (6, 10-12) FGPs are either sporadic or associated with familial adenomatous polyposis (FAP) syndrome. (13, 14) Both types are the same histologically, but dysplasia is common in FAP-associated FGPs (30–50%) and rare in sporadic FGPs (1%). (6, 10, 15) Histological examination of FGPs shows cystic dilatations of the oxyntic glands lined by parietal and chief cells with or without foveolar cells. (16, 17) These…

patients was 45.3 years (age range, 20 -70 years). The 14 patients with benign lesions had a mean age of 37.8 years, and the 16 patients with malignant lesions had a mean age of 51.9 years. It was found that the mean age for malignant lesions was higher than that for benign lesions and this difference was statistically significant (P = 0.002). This comes in agreement with the study of Bojanic et al. (10) who found that the mean age for benign lesions was 50 years and the mean age for malignant…

Exclusion of breast carcinoma by biopsy is indicated if mass, thickening, discharge, and pain are observed ? Fibroadenomas are benign tumors composed of both the stromal and epithelial elements of the breast.?16 ? Fibroadenomas account for 50% of breast biopsies in women aged older than 20 years and 75% in women aged younger than 20 years?16 ? Usually solitary; multiple lesions seen in 10% to 15% of patients?16 ? Mammography is of little help in distinguishing between cysts and fibroadenomas,…
