Infantile fibromatosis (desmoid type)--a case report.
Infantile fibromatosis represents the childhood counter part of musculoaponeurotic fibromatosis & arises as a solitary mass in skeletal muscle, adjacent fascia, aponeurosis or periosteum. The lesion is extremely rare. Microscopically it exists in two forms diffuse (mesenchymal) & desmoid. The less common desmoid form rarely occurs in infancy. Immunophenotype shows vimentin positivity with variable positivity with muscle markers. The differential diagnosis of this type is infantile fibrosarcoma. The tumor may locally recur if inadequately excised. We report a case of infantile fibromatosis of desmoid type occurring in 10 months male child for its extreme rarity.
