Gastrocutaneous syndrome is a rare autosomal dominant cutaneous condition characterized by multiple lentigines. [2]
Sézary disease, or Sézary syndrome, is a type of cutaneous T-cell lymphoma that was first described by Albert Sézary. The affected T cells, known as Sézary's cells or Lutzner cells, have pathological quantities of mucopolysaccharides. Sézary disease is sometimes considered a late stage of mycosis fungoides with lymphadenopathy.
Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration. This can be a secondary effect of a condition that increases a person's risk of forming blood clots, including a wide array of pathological and nonpathological conditions. Examples include hyperlipidemia, microvascular hematological or anemia states, nutritional deficiencies, hyper- and autoimmune diseases, and drugs/toxins.
Conradi–Hünermann syndrome is a rare type of chondrodysplasia punctata. It is associated with the EBP gene and affects between one in 100,000 and one in 200,000 babies.
Kindler syndrome is a rare congenital disease of the skin caused by a mutation in the KIND1 gene.
In medicine, a drug eruption is an adverse drug reaction of the skin. Most drug-induced cutaneous reactions are mild and disappear when the offending drug is withdrawn. These are called "simple" drug eruptions. However, more serious drug eruptions may be associated with organ injury such as liver or kidney damage and are categorized as "complex". Drugs can also cause hair and nail changes, affect the mucous membranes, or cause itching without outward skin changes.
Naxos disease is a cutaneous condition characterized by a palmoplantar keratoderma. The prevalence of the syndrome is up to 1 in every 1000 people in the Greek islands.
Tooth and nail syndrome is a rare disorder, first described in 1965, characterized by nails that are thin, small, and friable, and which may show koilonychia at birth.
Epidermal nevus syndrome, also known as Feuerstein and Mims syndrome, and Solomon's syndrome is a rare disease that was first described in 1968 and consists of extensive epidermal nevi with abnormalities of the central nervous system (CNS), skeleton, skin, cardiovascular system, genitourinary system and eyes. However, since the syndrome's first description, a broader concept for the "epidermal nevus" syndrome has been proposed, with at least six types being described:
Xanthoma disseminatum is a rare cutaneous condition that preferentially affects males in childhood, characterized by the insidious onset of small, yellow-red to brown papules and nodules that are discrete and disseminated.
Bazex–Dupré–Christol syndrome is a very rare condition inherited in an X-linked dominant fashion. Physical findings typically include follicular atrophoderma, multiple basal cell carcinomas, hypotrichosis, and hypohidrosis.
Pilomatricoma is a benign skin tumor derived from the hair matrix. These neoplasms are relatively uncommon and typically occur on the scalp, face, and upper extremities. Clinically, pilomatricomas present as a subcutaneous nodule or cyst with unremarkable overlying epidermis that can range in size from 0.5 to 3.0 cm, but the largest reported case was 24 cm.
Blue rubber bleb nevus syndrome is a rare disorder that consists mainly of abnormal blood vessels affecting the skin or internal organs – usually the gastrointestinal tract. The disease is characterized by the presence of fluid-filled blisters (blebs) as visible, circumscribed, chronic lesions (nevi).
UV-sensitive syndrome is a cutaneous condition inherited in an autosomal recessive fashion, characterized by photosensitivity and solar lentigines. Recent research identified that mutations of the KIAA1530 (UVSSA) gene as cause for the development of UV-sensitive syndrome. Furthermore, this protein was identified as a new player in the Transcription-coupled repair (TC-NER).
Poikiloderma vasculare atrophicans (PVA), is a cutaneous condition characterized by hypo- or hyperpigmentation, telangiectasia and skin atrophy. Other names for the condition include prereticulotic poikiloderma and atrophic parapsoriasis. The condition was first described by pioneer American pediatrician Abraham Jacobi in 1906. PVA causes areas of affected skin to appear speckled red and inflamed, yellowish and/or brown, gray or grayish-black, with scaling and a thinness that may be described as "cigarette paper". On the surface of the skin, these areas may range in size from small patches, to plaques, to neoplasms.
Haber syndrome is a cutaneous disorder of hyperpigmentation characterized by reticulated pigmentation of the person's skin. A rare genodermatosis, its key features include "rosacea-like facial eruption[,] reticulated hyperpigmentation of major flexures, comedones on the back and neck, and pitted facial scars."
Neonatal ichthyosis–sclerosing cholangitis syndrome is a cutaneous condition which is characterized by hypotrichosis of the scalp, alopecia, ichthyosis and sclerosing cholangitis. Only 5 cases from 3 families worldwide have been described in medical literature. It caused by mutations in the Claudin 1 gene.
Keratosis linearis with ichthyosis congenita and sclerosing keratoderma syndrome is a rare cutaneous condition characterized by ichthyosis and keratoderma.
Laryngo-onycho-cutaneous syndrome is a rare epithelial disorder inherited in an autosomal recessive fashion. It is characterized by abnormalities in the larynx, nails, and skin ("cutaneous"). The disorder is only found in Punjabi Muslims and only a few cases have been reported.
Stiff skin syndrome is a cutaneous condition characterized by ‘rock hard’ induration, thickening of the skin and subcutaneous tissues, limited joint mobility, and mild hypertrichosis in infancy or early childhood. Immunologic abnormalities or vascular hyperactivity are not present in patients.
Proteus-like syndrome (PLS) is a condition similar to Proteus syndrome, but with an uncertain cause. It's characterized by skeletal and hamartous overgrowth of multiple tissues, nevi in cerebriform connective tissue, blood vessel malformations and linear epidermal nevi.
