Sclerotic fibromas of the skin

Collagenous fibroma of the deltoid muscle: clinical, surgical and histopathological aspects

“…This benign fibrous proliferation is heavily collagenized and relatively hypocellular, like collagenous fibroma; it differs from the latter in that it preferentially affects the dermis and features thicker hyalinized collagen bundles with intervening stromal mucin clefts. In contrast to collagenous fibroma, sclerotic fibromas are small lesions, usually measuring less than 1 cm in diameter [16]. Calcifying fibrous pseudotumor (childhood fibrous tumor with psammoma bodies) shares with collagenous fibroma features such as lobular contour and a collagenrich matrix, but differs from it clinically by preferentially affecting children and young adults, and histologically by a less abundant mesenchymal component, a patchy lymphoplasmacytic infiltrate, and scattered psammomatous or dystrophic calcifications [17].…”

Juxta-artikuläre fibroide Knoten und Acrodermatitis chronica atrophicans bei Lyme-Borreliose im Spätstadium

“…Die postulierte Assoziation des storiformen Kollagenoms mit Cowden Syndrom wurde jedoch revidiert zugunsten einer Interpretation als unspezifischer Residualzustand z.B. von Histiozytomen [13,14].…”

Sclerotic fibroma‐like change in various neoplastic and inflammatory skin lesions: is sclerotic fibroma a distinct entity?

“…1 In 1989, Rapini and Golitz detailed 11 cases of solitary sclerotic fibroma (SFS) in the absence of Cowden's disease and suggested the term SFS of the skin. 2 This uncommon entity has been characterized as a well-circumscribed, hypocellular neoplasm with rather distinct hyalinized bands of collagen. 2,3 Sclerotic fibroma-like changes have been described in other lesions such as melanocytic nevi, dermatofibromas, lipomas, tendon sheath fibromas, giant cell collagenomas, neurofibromas, angiofibromas, erythema elevatum diutinum, and chronic folliculitis.…”

[4][5][6][7][8][9][10][11][12][13] Controversy has arisen with some dermatopathologists asserting that sclerotic fibroma is an evolutionary end-point of a pre-existing lesion, while others contend that SFS is a distinct clincopathologic entity.…”
