Aplasia cutis congenita (ACC) is a rare, heterogeneous group of congenital disorders characterized by focal or widespread absence of the skin [ 1,2 ]. ACC can occur anywhere on the body, but the vast majority of cases occur on the scalp Aplasia cutis congenita describes the congenital absence of skin. The commonest form presents as a scalp defect at birth. Aplasia cutis is also a component of a number of genetic syndromes Aplasia cutis congenita is a rare condition that causes newborns to have skin missing from parts of their body. In some cases, the underlying structures beneath the skin, such as bone, may also not.. Inherited or Congenital Pure Red Cell Aplasia (Diamond-Blackfan Anemia): Diamond-Blackfan anemia is a genetic condition usually diagnosed during the first two years of life. About half of patients also have physical malformations or mental retardation. Only several hundred cases have been reported worldwide
Pure red cell aplasia (PRCA) is a rare condition that affects the bone marrow. Bone marrow contains stem cells which develop into the red blood cells that carry oxygen through the body, the white blood cells that fight infections, and the platelets that help with blood clotting , also known as Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) or vaginal agenesis, is a congenital malformation characterized by a failure of the Müllerian duct to develop, resulting in a missing uterus and variable degrees of vaginal hypoplasia of its upper portion
Abstract Two infants with congenital aplasia of the thymus were found to have normal polymorphonuclear-leukocyte function, immunoglobulins and antibody formation. Delayed hypersensitivity,.. 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.

It may be associated with other congenital abnormalities. [from NCI Congenital aplasia of scrotum (204907006) Recent clinical studies. Etiology. Novel truncating variants expand the phenotypic spectrum of KAT6B-related disorders. Brea-Fernández A, Dacruz D, Eirís J, Barros F, Carracedo. Thankfully, congenital thymic aplasia is a rare disease. It occurs in around 1 in every 4,000 live births in the United States. As mentioned at the beginning, congenital thymic aplasia is a disease that you are born with (congenital). The disease is the result of the deletion of a part of chromosome 22 defective development or congenital absence of a limb, organ, or other body part Congenital aplasia of the heel pad is a descriptive term for a rare anomaly of the foot noted at birth or within the first few years of life. The normal heel pad is a specialised structure that lies between the os calcis and plantar skin consisting of microchambers and macrochambers of adipose tissue divided by intricate fibroelastic septations.
Aplasia or hypoplasia of the epiglottis in an adult is rarely reported congenital anomaly of the larynx. Most patients with epiglottic aplasia have presented fatal symptom of respiratory distress and severe aspiration in infancy or childhood. We present a case of congenital absence of the epiglottis found in a 33-year-old woman complaining of. In an attempt to describe the morphofunctional consequences of uni- and bilateral aplasia of the common carotid artery (CCA), which is usually a vascular source of the external carotid (ECA) and internal carotid (ICA) arteries, we investigated online databases of anatomical and clinical papers published from the 18th century to the present day.

Congenital absence of the lateral sesamoid bone is a relatively rare condition. Literature review reveals very few case presentations relevant to this condition. We present a case of lateral sesamoid aplasia that was incidentally detected upon roentgenograms of a patient presenting with a fracture to the base. Thyroid gland - Aplasia / hypoplasia. 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
. Diamond-Blackfan anemia is a congenital form of PRCA. Acquired PRCA may be either a primary disorder or secondary to some other disorder or agent About two thirds of cases are associated with other congenital disorders, including Adams-Oliver syndrome (aplasia cutis congenita with partial aplasia of the skull bones and terminal transverse limb malformations), Holt-Oram syndrome, TAR (thrombocytopenia-absent radius) syndrome, Fanconi anemia, and VACTERL (vertebral anomalies, anal atresia. 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. There are many types or examples of aphasia. It would include the aplasia cutis congenital wherein there is a congenital absence of skin; acquired pure red cell aplasia which is also called as the erythroblastopenia, a type of anemia; radial aplasia or the formation of the radius bone in the arm; Sertoli. Pulmonary aplasia is a rare congenital pathology in which there is unilateral or bilateral absence of lung tissue. It is different from pulmonary agenesis, which although similar, the main difference is a short-blind ending bronchus in aplasia 3.. It is usually unilateral, as bilateral pulmonary aplasia is not viable. It is frequently associated with other congenital abnormalities, mainly. Congenital aplasia of the uterus or vagina may occur in two variants: showing the normal development of muscular and serosal external layers, but without development of th Aplasia or absence of pituitary gland is a rare congenital anomaly which presents with consequences of multiple pituitary hormone deficiency and involves absence of anterior and posterior pituitary gland and the pituitary stalk [1, 2]. Neonatal hypoglycaemia is common, but when associated with microphallus or micropenis  should raise the.
Congenital bilateral aplasia of the vas deferens (CBAVD), which leads to male infertility, may occur in isolation or as a manifestation of cystic fibrosis. Kaplan et al. (1968) found that males with cystic fibrosis are infertile because of failure of normal development of the vas deferens
Congenital solitary kidneys, which are susceptible to renal failure, have been considered mostly due to unilateral renal agenesis and partly due to renal aplasia. Risk of familial recurrence and of other associated anomalies is known to be much higher in renal agenesis than in renal aplasia. However, differential diagnosis between the two renal. Aplasia cutis congenita (ACC) is defined as congenital localized absence of skin. The skin appears as a thin, transparent membrane through which the underlying structures are visible. The location is usually on the scalp (Evers et al., 1995). Approximately 20 to 30% of cases have underlying osseous involvement (Elliott and Teebi, 1997) Q45.0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2021 edition of ICD-10-CM Q45.0 became effective on October 1, 2020. This is the American ICD-10-CM version of Q45.0 - other international versions of ICD-10 Q45.0 may differ. Applicable To.

The paramesonephric ducts are paired embryonic ducts that develop into the anterior vagina, cervix, uterus, and uterine tube. Segmental aplasia of the paramesonephric ducts results in anomalies of those organs. The aplasia (obstruction) may be located in a segment of the uterine tube.
The complete absence of the chiasm (chiasmal aplasia) is a rare clinical condition. Hypoplasia of the optic nerve and congenital nystagmus are almost invariably associated characteristics. Microphthalmos or anophthalmos are common features in chiasmal aplasia, while central nervous system abnormalities are less frequent.

EB with congenital absence of skin is rare and its exact incidence is unknown. Aplasia cutis congenita is seen in 1-2 per 10,000 births . EB with congenital absence of skin can be considered a rare form of aplasia cutis congenita, but the proportion of aplasia cutis congenita that can be classified as EB with congenital absence of skin is. Congenital aplasia of the epiglottis is a rare condition with variable presentation ranging from respiratory distress requiring surgical airway to an asymptomatic finding. Epiglottic aplasia is presumed to be caused by arrest of development of laryngeal structures and is most commonly associated with syndromic conditions

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. Here is a clinical case by Dr. Giovanni Polizzi. It shows the treatment of a case of congenital aplasia with a NobelActive implant.Learn more: https://goo.gl..
