Sebaceous Adenoma
A sebaceous adenoma, a type of adenoma, a cutaneous condition characterized by a slow-growing tumor usually presenting as a pink, flesh-coloured, or yellow papule or nodule. James et al. 2006 Rapini et al. 2007 Significance Sebaceous adenomas, in isolation, are not significant; however, they may be associated with Muir-Torre syndrome, a genetic condition that predisposes individuals to cancer. It is also linked to hereditary nonpolyposis colorectal cancer (Lynch syndrome). It is not the same as "adenoma sebaceum" by F. Balzer and P.E. Ménétrier (1885). The term "adenoma sebaceum" is a misnomer for ''facial angiofibromas'' associated with tuberous sclerosis complex.

Micrograph
A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Félix Balzer
Félix Balzer (4 April 1849 – 15 March 1929) was a French physician, specialising in dermatology and pathology. Balzer gave an early description of pseudoxanthoma elasticum in 1884. He used the term "''xanthome elastique''" but subsequently it was found not to be a form of xanthomatosis. Balzer is also responsible for coining the term "''adénomes sébacés''" (adenoma sebaceum) to describe the papular facial rash of tuberous sclerosis. Again, this term proved to be incorrect since the papules were neither adenoma nor derived from sebaceous glands. Between 1880 and 1887, Balzer was a director of the histology laboratory in the Faculty of the hospital Saint Louis. He became a member of the ''Académie de Médecine'' in 1908. He was also president of ''la Société Française de Dermatologie''.

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...

Sebaceous Hyperplasia
Sebaceous hyperplasia is a disorder of the sebaceous glands in which they become enlarged, producing flesh-colored or yellowish, shiny, often umbilicated bumps on the face. Newly formed nodules often swell with sweating (which is pathognomonic for the condition), but this diminishes over time. Sebaceous glands are glands located within the skin and are responsible for secreting an oily substance named sebum. They are commonly associated with hair follicles but they can be found in hairless regions of the skin as well. Their secretion lubricates the skin, protecting it from drying out or becoming irritated. Sebaceous hyperplasia generally affects newborns as well as middle-aged to elderly adults. The symptoms of this condition are 1–5 mm papules on the skin, mainly on the forehead, nose and cheeks, and seborrheic facial skin. The papules may be cauliflower-shaped. In infants, acne is sometimes associated with sebaceous hyperplasia. File:Photography of sebaceous hyperplas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sebaceous Carcinoma
Sebaceous carcinoma, also known as sebaceous gland carcinoma (SGc), sebaceous cell carcinoma, and meibomian gland carcinoma is an uncommon malignant cutaneous tumor. Most are typically about 1.4 cm at presentation. SGc originates from sebaceous glands in the skin and, therefore, may originate anywhere in the body where these glands are found. SGc can be divided into 2 types: periocular and extraocular. The periocular region is rich in sebaceous glands making it a common site of origin. The cause of these lesions in the vast majority of cases is unknown. Occasional cases may be associated with Muir-Torre syndrome. SGc accounts for approximately 0.7% of all skin cancers, and the incidence of SGc is highest in Caucasian, Asian, and Indian populations. Due to the rarity of this tumor and variability in clinical and histological presentation, SGc is often misdiagnosed as an inflammatory condition or a more common neoplasm. SGc is commonly treated with wide local excision or Mohs micr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuberous Sclerosis Alliance
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tuberous Sclerosis Complex
Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin. A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease. TSC is caused by a mutation of either of two genes, ''TSC1'' and ''TSC2'', which code for the proteins hamartin and tuberin, respectively, with ''TSC2'' mutations accounting for the majority and tending to cause more severe symptoms. These proteins act as tumor growth suppressors, agents that regulate cell proliferation and differentiation. Prognosis is highly variable and depends on the symptoms, but life expectancy is normal for many. The prevalence of the disease is estimated to be 7 to 12 in 100,000. The disease is often abbreviated to tuberous sclerosis, which refers to the hard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pierre Eugène Ménétrier
Pierre Eugène Ménétrier (7 December 1859 – 22 August 1935) was a French pathologist from Paris. He is remembered for his description of a rare gastric disorder that was later to become known as Ménétrier's disease. In 1888 Ménétrier first described the disorder while performing post-mortem studies, noticing hyperplastic changes of the gastric mucosa in cadavers. At the time, he named the disease ''polyadenomes en nappe''. Although Ménétrier understood the debilitative factors of the disease, it wouldn't be until years later that the associated protein-losing enteropathic aspects of the disorder were realized. Other names for "Ménétrier's disease" are "hyperplastic hypersecretory gastropathy" and "giant hypertrophic gastritis". He published his findings in a treatise titled ''Des polyadenomes gastriques et de leurs rapports avec le cancer de l’estomac''. Ménétrier published writings on Byzantine and Greco-Roman medicine, and was a member of the International S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
