Diffuse infantile fibromatosis is a rare condition affecting infants during the first three years of life. This condition is a multicentric infiltration of muscle fibers with fibroblasts resembling those seen in aponeurotic fibromas, presenting as lesions and tumors confined usually to the muscles of the arms, neck, and shoulder area [1]: 607 Diffuse infantile fibromatosis is characterized by ...
Juvenile hyaline fibromatosis, also termed fibromatosis hyalinica multiplex juvenilis and the Murray–Puretic–Drescher syndrome, an autosomal recessive inherited genetic disease. [9] Infantile digital fibromatosis, also termed inclusion body fibromatosis [10] or Reye tumor [11] Fibroma of tendon sheath [12]
Other names include musculoaponeurotic fibromatosis, referring to the tendency of these tumors to be adjacent to and infiltrating deep skeletal muscle, aggressive fibromatosis and desmoid tumor. A clear difference should be made between intra-abdominal and extra-abdominal localizations. Fibromatosis is a different entity from neurofibromatosis.
IMF tumors are usually painless, well-encapsulated, rubbery to hard, and freely movable-to-fixed masses. [8] They may be evident at birth in up to 60% of cases [4] but generally go undetected until they [9] are diagnosed in the first year of life, [8] uncommonly in older infants and young (<10 years/old) children, [4] or rarely in older children and adults (one individual was diagnosed with ...
Fibromatosis colli (FMC), also termed sternocleidomastoid tumor of infancy, pseudotumor of infancy, [1] and infancy sternocleidomastoid pseudotumor, [2] is an uncommon (incidence: 0.4%–1.3% of live births), congenital tumor in one of the two sternocleidomastoid neck muscles although rare cases have presented with a FMC tumor in both sternocleidomastoid muscles. [3]
Gardner syndrome is also associated with familial adenomatous polyposis and may manifest as aggressive fibromatosis (desmoid tumors) of the retroperitoneum. [11] Desmoid tumors arise most frequently from the aponeurosis of the rectus abdominal muscle of multiparous women. The extra-abdominal form is rare and desmoids of the breast may arise in ...
Infantile digital fibromatosis (IDF), also termed inclusion body fibromatosis or Reye's tumor, usually occurs as a single, small, asymptomatic, nodule in the dermis on a finger or toe [1] of infants and young children. [2] IMF is a rare disorder with approximately 200 cases reported in the medical literature as of 2021. [3]
[25] [15] Rarely, amputation may be necessary due to injury caused by the tumor or its treatments. [18] Tumors may be misdiagnosed (30–40%) [25] due to their rarity and a lack of knowledge; patients may initially be given inappropriate treatment or poor prognoses due to misdiagnosis with conditions such as malignant sarcoma.
