Infantile hemangiopericytoma is a cutaneous condition characterized by single or multiple dermal and subcutaneous nodules that may be alarmingly large at birth or grow rapidly. [1] [2]
An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. Other names include capillary hemangioma, "strawberry hemangioma", strawberry birthmark and strawberry nevus. and formerly known as a cavernous hemangioma. They appear as a red or blue raised lesion on the skin. Typically, they begin during the first four weeks of life, growing until about five months of life, and then shrinking in size and disappearing over the next few years. Often skin changes remain after they shrink. Complications may include pain, bleeding, ulcer formation, disfigurement, or heart failure. It is the most common tumor of orbit and periorbital areas in childhood. It may occur in the skin, subcutaneous tissues and mucous membranes of oral cavities and lips as well as in extracutaneous locations including the liver and gastrointestinal tract.
Angiomas are benign tumors derived from cells of the vascular or lymphatic vessel walls (endothelium) or derived from cells of the tissues surrounding these vessels.
Tuberculosis verrucosa cutis is a rash of small, red papules and nodules in the skin that may appear two to four weeks after inoculation by Mycobacterium tuberculosis in a previously infected and immunocompetent individual.
Hemangioendotheliomas are a family of vascular neoplasms of intermediate malignancy.
A hemangiopericytoma is a type of soft-tissue sarcoma that originates in the pericytes in the walls of capillaries. When inside the nervous system, although not strictly a meningioma tumor, it is a meningeal tumor with a special aggressive behavior. It was first characterized in 1942.
A vascular tumor is a tumor of vascular origin; a soft tissue growth that can be either benign or malignant, formed from blood vessels or lymph vessels. Examples of vascular tumors include hemangiomas, lymphangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular tumor.
Cerebrotendinous xanthomatosis, also called cerebral cholesterosis, is an autosomal recessive form of xanthomatosis. It falls within a group of genetic disorders called the leukodystrophies.
Leishmania infantum is the causative agent of infantile visceral leishmaniasis in the Mediterranean region and in Latin America, where it has been called Leishmania chagasi. It is also an unusual cause of cutaneous leishmaniasis, which is normally caused by specific lineages. Wild canids and domestic dogs are the natural reservoir of this organism. The sandfly species Lutzomyia longipalpis serves as the primary vector for the transmission of the disease.
Sialin, also known as H(+)/nitrate cotransporter and H(+)/sialic acid cotransporter, is a protein which in humans is encoded by the SLC17A5 gene.
Gianotti–Crosti syndrome, also known as infantile papular acrodermatitis, papular acrodermatitis of childhood, and papulovesicular acrolocated syndrome, is a reaction of the skin to a viral infection. Hepatitis B virus and Epstein–Barr virus are the most frequently reported pathogens. Other viruses implicated are hepatitis A virus, hepatitis C virus, cytomegalovirus, coxsackievirus, adenovirus, enterovirus, rotavirus, rubella virus, HIV, and parainfluenza virus.
Infantile systemic hyalinosis is an allelic autosomal-recessive condition characterized by multiple skin nodules, hyaline deposition, gingival hypertrophy, osteolytic bone lesions and joint contractures.
Infantile acropustulosis is an intensely itchy vesicopustular eruption of the hands and feet. Involvement of scabies has been suggested.
Infantile acne is a form of acne that begins in very young children. Typical symptoms include inflammatory and noninflammatory lesions, papules and pustules most commonly present on the face. No cause of infantile acne has been established but it may be caused by increased sebaceous gland secretions due to elevated androgens, genetics and the fetal adrenal gland causing increased sebum production. Infantile acne can resolve by itself by age 1 or 2. However, treatment options include topical benzyl peroxide, topical retinoids and topical antibiotics in most cases.
A myxoid cyst is a cutaneous condition often characterized by nail plate depression and grooves.
Kraurosis vulvae or vulvar lichen sclerosus (VLS) is a cutaneous condition characterized by atrophy and shrinkage of the skin of the vagina and vulva often accompanied by a chronic inflammatory reaction in the deeper tissues.
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.
Diffuse neonatal hemangiomatosis (DNH) is a potentially fatal disorder where multiple benign (non-cancerous) blood vessel tumors (hemangiomas) are present in the skin and other organs. The mortality rate of diffuse neonatal hemangiomatosis is 50-90%. This disease is normally found in female Caucasian infants. The most common site of internal organ damage, or lesions, is the liver, which can redirect blood away from the heart and cause arteriovenous shunting. This can cause high cardiac output, leading to further complications such as congestive heart failure. This condition affecting the liver is also known as infantile hepatic hemangioma (IHH). Other sites of internal organ damage can include the intestines, nervous system, lungs, and sometimes the skeletal system. Early detection and treatment with steroids results in most newborn babies with this disease remaining healthy, with serious problems developing for some individuals during the hemangioma's growth phase.
Benign neonatal hemangiomatosis is a rare skin condition that presents in infancy with multiple benign tumors called infantile hemangiomas, but without hemangiomas in other organs.
