keratosis/phosphatase

BACKGROUND Inositol Phosphate 5-Phosphatase (INPP5A) has been shown to play a role in development and progression of cutaneous squamous cell carcinoma (cSCC). The goal of the current study is to explore the prognostic value of INPP5A expression in cSCC. METHODS A total of 189 cases of actinic

Phosphatase and tensin homolog (PTEN) gene mutations are associated with a spectrum of clinical disorders characterized by skin lesions, macrocephaly, hamartomatous overgrowth of tissues, and an increased risk of cancers. Autism has rarely been described in association with these variable clinical

The correlation between proteinase activities and invasive and metastatic potentials was investigated by comparing three different kinds of tumors. Extracts from tumor homogenate of 11 squamous cell carcinoma (SCC), 5 basal cell epithelioma (BCE), and 8 seborrheic keratosis (SK) were prepared in

Cutaneous squamous cell carcinoma (SCC) occurs commonly and can metastasize. Identification of specific molecular aberrations and mechanisms underlying the development and progression of cutaneous SCC may lead to better prognostic and therapeutic approaches and more effective chemoprevention

Cowden syndrome (CS) is a rare dominantly inherited multisystem disorder, characterized by an extraordinary malignant potential. In 80% of cases, the human tumor suppressor gene phosphatase and tensin homolog (PTEN) is mutated. We present a case of a 17-year-old boy with genetically confirmed CS and

Kidney transplant recipients suffer in the long-term from several cutaneous disorders linked to the transplantation. We had the opportunity to observe several patients presenting with pre-epitheliomatous keratoses and cutaneous carcinomas associated with warts. We report herein on five cases that

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer and frequently progresses from an actinic keratosis (AK), a sun-induced keratinocyte intraepithelial neoplasia (KIN). Epigenetic mechanisms involved in the phenomenon of progression from AK to cSCC remain to be

We report the features of a group of 41 patients with Paget's disease (PD) who were identified in a cross sectional study in the "Sierra de la Cabrera" (Madrid). As the screening test, we used serum alkaline phosphatase quantification, and the diagnosis was confirmed by radiological study. This

A 24-year-old woman slowly developed mild unsteadiness of gait. Neurological examination revealed mild dysmetria of the left upper and lower limbs. Standing and gait were unsteady, and tandem gait was impossible. Cranial magnetic resonance imaging (MRI) showed an enlarged left cerebellar hemisphere

Cowden's disease, also known as a kind of phosphatase and tensin homolog (PTEN) hamartoma tumor syndrome, is an uncommon autosomal dominant inherited complex disorder with various hamartomatous growths of multiple organs involving all three germ cell layers. It usually manifests with polyps

Cowden disease is an autosomal dominant syndrome characterized by facial trichilemmomas, acral keratoses, papillomatous papules, mucosal lesions, and an increased risk for breast and nonmedullary thyroid cancer. Here, we describe a novel PTEN splicing site mutation in a family with classical Cowden

Cowden syndrome is a rare, autosomal-dominant, multisystem disorder characterized by hamartomatous tissue overgrowth and an increased risk of breast, thyroid, and endometrial cancers. Most of the cases arise from germline mutations of the phosphatase and tensin homologue tumor suppressor gene. An

Cytoenzymatic examinations of epithelium in swabs taken from under metal and metal-acrylic bridges have been performed in 25 men without clinically perceptible changes in mucous membrane. Reactions on acid phosphatase, alkaline phosphatase and unspecific esterase have been performed. The results

Ultraviolet (UV) radiation in sunlight is the major environmental cause of skin cancer. PTEN (phosphatase and tensin homolog deleted on chromosome 10) is a proven critical tumor suppressor. We report here that UVB downregulates PTEN in primary human keratinocytes, human HaCaT keratinocytes and mouse
