Gardner-type fibroma emerges as an exceptionally encountered, benign soft tissue lesion demonstrating morphological features akin to nuchal-type fibroma. Majority (~90%) of lesions are concurrent with familial adenomatous polyposis (FAP) or Gardner’s syndrome delineating specific germline mutations within the APC gene.
Tumefaction is comprised of haphazardly disseminated thickened bands of collagen commingled with a population of bland fibroblasts wherein the cellular component appears to entrap adjacent soft tissue.
Neoplasm commonly occurs within infants, paediatric population or adolescents. An estimated 45% subjects may demonstrate desmoid-type fibromatosis.
Gardner-type fibroma may be confined to superficial or deep seated soft tissue. No site of disease emergence is exempt [1,2].
Gardner-type fibroma may preliminarily indicate the occurrence of Gardner’s syndrome with concurrent genetic mutations within the APC gene. Chromosomal mutation confined to chromosome 5q21 is exemplified [2,3].
Although Gardner’s syndrome is comprised of colonic polyps, osteomas and anomalies within the retinal epithelium, cutaneous manifestations commonly emerge as epidermoid cysts layered by stratified squamous epithelium [2,3].
Grossly, neoplasm appears as an inadequately circumscribed, firm, rubbery, plaque-like, white to tan or pink lesion of magnitude varying from one centimetre to 10 centimetres. Cut surface appears grey/white and yellowish with fibrotic areas demonstrating entrapped mature adipose tissue [3,4].
Upon microscopy, tumefaction expounds haphazard dissemination of thickened collagen bundles commingled with hypo-cellular areas comprised of bland fibroblasts. Miniature vascular articulations appear admixed with the cellular component.
Neoplasm depicts a plaque-like pattern of tumour evolution along with infiltration of adjacent anatomic structures [4,5].

Gardner-type fibroma appears immune reactive to CD34, cyclin D1, vimentin and nuclear β catenin.
Tumour cells appear immune non reactive to muscle specific actin (MSA), smooth muscle actin (SMA), desmin, oestrogen receptors (ER) and progesterone receptors (PR) [5,6].
Gardner-type fibroma requires segregation from neoplasms as familial adenomatous polyposis, Gardner’s syndrome, Turcot’s syndrome and attenuated variants of familial polyposis associated with chromosomal mutation of APC gene [6,7].
Neoplasm may be appropriately alleviated by surgical extermination, pre-eminently adopted for superior cosmetic outcomes [6,7].
