Aplasia cutis congenita Genetic and Rare Diseases

  1. Aplasia cutis congenita is a condition in which there is congenital (present from birth) absence of skin, with or without the absence of underlying structures such as bone. It most commonly affects the scalp, but any location of the body can be affected
  2. Aplasia Cutis Congenita is a rare disorder with a complicated pattern of inheritance. Babies are born with the absence of certain layer (s) of skin, most often on the scalp, but also on the trunk, and/or arms and legs. The affected area is typically covered with a thin, transparent membrane
  3. Nonsyndromic aplasia cutis congenita is a condition in which babies are born with localized areas of missing skin (lesions). These areas resemble ulcers or open wounds, although they are sometimes already healed at birth. Lesions most commonly occur on the top of the head (skull vertex), although they can be found on the torso or limbs
  4. Congenital aplasia and hypoplasia of the epiglottis are rare congenital laryngeal anomalies and the majority are associated with a syndrome. Early diagnosis and management in the form of fundoplication/gastrostomy and tracheotomy when required may improve outcomes
  5. Aplasia cutis congenita is a skin disorder which causes children to be born with a missing patch of skin. Aplasia cutis congenita may occur by itself or as a symptom of other disorders such as Johanson-Blizzard syndrome and Adams-Oliver syndrome. Aplasia cutis congenita may be inherited or occur without any family history of the condition

Congenital bilateral absence of the vas deferens occurs in males when the tubes that carry sperm out of the testes (the vas deferens) fail to develop properly. Although the testes usually develop and function normally, sperm cannot be transported through the vas deferens to become part of semen. As a result, men with this condition are unable.

Congenital anomalies of the thyroid are uncommon, with a prevalence of 1.4 cases per 1000 (J Pathol 1989;159:135) Relative frequency of ectopic thyroid tissue is slightly more common than anatomic abnormalities of eutopic thyroid gland; however it is often subclinica

Pure red cell aplasia (PRCA) is a syndrome defined by a normocytic normochromic anemia with severe reticulocytopenia and marked reduction or absence of erythroid precursors from the bone marrow. Diamond-Blackfan anemia is a congenital form of PRCA.

Aplasia Cutis Congenita. Aplasia cutis congenita (epitheliogenesis imperfecta) is a very rare congenital and perhaps inherited failure to form certain layers of skin. 1a, 5 The condition is a developmental failure of skin fusion. Dermis, epidermis, and fat may all be missing, or single layers may be absent Bullous aplasia cutis congenita demonstrates a fibrovascular or edematous connective tissue similar to that seen in encephaloceles and meningoceles, suggesting it may also be related to a neural tube defect. Focal preauricular dermal dysplasia is a form of aplasia cutis congenital occurring in front of the ear With hypoplasia of the right vertebral artery, a congenital type of underdevelopment and a decrease in the diameter of the vessel are observed. Of course, the blood supply to the brain in this case is significantly impaired. If there are other problems in the Willis Circle, then there is a danger of developing serious brain damage

Thrombocytopenia-absent radius (TAR) syndrome is a rare disorder that is present at birth (congenital). It is characterized by low levels of platelets in the blood (thrombocytopenia) and absence (aplasia) of the long, thin bones of the forearms (radii). Other abnormalities are often present including additional skeletal defects such as absence. Aplasia comes from a Greek word a which means not and plasis meaning molding.

The following congenital cases are not meant to be a comprehensive overview of congenital ear malformations, but rather a brief overview of some of the more common entities covering the external ear, middle and inner ear and a few vascular anomalies. Case 1. Bony external auditory atresia (EAC) Case 2. Cochlear aplasia. Case 3. Common cavity. In addition to the aplasia or hypoplasia, congenital narrowing of the upper airway also affects many patients. Pulmonary sequestration Resection is recommended, even in asymptomatic patients, to prevent infection, hemorrhage, shunting from arteriovenous anastomoses, or compression of normal lung mass leading to respiratory distress Pure red cell aplasia (PRCA) is a rare disorder of blood production in which the bone marrow, the spongy tissue in the center of the bones, fails to function in an adequate manner resulting in anemia. Red blood cells are responsible for carrying oxygen to the entire body. The anemia can be either acquired, genetic (inherited) or induced by drugs Congenital aural atresia (CAA) is characterized by hypoplasia or aplasia of external auditory canal associated with auricular deformity. It also embodies a spectrum of temporal bone abnormalities including anomalies of middle ear, ossicles, facial nerve, oval window, round window, mastoid pneumatization, temporomandibular joint and occasionally inner ear and vascular anomalies

Abstract. THIS exceedingly rare condition has been variously designated as agenesis of high or low degree, aplasia, absence or defect in whole or in part of either lung, the choice of a descriptive term having depended largely upon whether or not a rudimentary bronchus or aplastic lung could be demonstrated. Accordingly, in 1912, Schneider (1. Congenital skin aplasia on the limb is a sharply demarcated lesion characterized by the absence of skin, most frequently involving both epidermis and dermis. The lesion resembles an ulceration, with a smooth pink surface where epidermal coverage is either absent or vestigial. Dermis, if present, is thin and lacks skin appendages Aplasia, Congenital Pure Red Cell. Pure red cell aplasia (PRCA) is an uncommon disorder in which maturation arrest occurs in the formation of erythrocytes. [1, 2] Erythroblasts are virtually absent in bone marrow; however, white blood cell and platelet production are normal. The anemia due to PRCA is usually normocytic but can be macrocytic The brain, spinal cord, and skin are all derived from the embryonic ectoderm; this common derivation leads to a high association between central nervous system dysraphic malformations and abnormalities of the overlying skin. A myelomeningocele is an obvious open malformation, the identification of which is not usually difficult. However, the relationship between congenital spinal cord.

Factors contributing to pathology develops before birth on the stage of fetal development. This is a congenital defect, so parents are still in the planning stage of pregnancy should take into account the many nuances. Causes hypoplasia of the future are such: injuries (e.g., bruises) of the pregnant woman; infectious diseases of the mother. Pure red cell aplasia (PRCA) is defined as anemia with absent reticulocytes and marrow erythroid precursor cells. This rare aregenerative anemia has a number of interesting clinical associations.
