Calcifying aponeurotic fibroma of the thigh: A differential diagnosis for infant knee contracture and leg length inequality (a case report)

The Nonage Concretion-Calcifying Aponeurotic Fibroma

“…Lesions are located upon palm or fingers while involving the hand whereas majority of lesions are situated upon plantar or ankle region, when implicating the foot. Toes are also incriminated [3,4]. Generally, deep-seated, volar fascia, tendons, and aponeuroses of hand or distal upper or lower extremities are incriminated.…”

“…Calcifying aponeurotic fibroma can also arise from connective tissue of the neck, abdominal wall, lumbar region, knee, thigh, forearm, elbow and arm. Additionally, tumefaction is discerned upon sites such as scalp, gluteal region, popliteal fossa and supraclavicular region [3,4].…”

“…Evaluation of a cogent tissue specimen is crucial for disease discernment. Grossly, multiple, pale to tan, soft tissue fragments or a firm, pale, infiltrative mass of magnitude below < 3 centimetres is denominated [4]. Macroscopically, poorly defined, firm or rubbery, greyish/ white tumefaction is delineated which is often adherent to circumscribing, dense, fibro-connective tissue such as a tendon, fascia or periosteum.…”

“…Focal, punctate calcification may be detected, thus engendering a gritty sensation upon the cut surface. Calcifying aponeurotic fibroma demonstrates an ill-defined outline and variable consistency of rubbery to firm [4,5]. A nodular or infiltrative, grey/ white, gritty mass is exemplified within the subcutaneous tissue.…”

“…A tendon may Cancer Therapy & Oncology International Journal appear as calcified. The nodule is usually beneath < 3 centimetres when confined to hands or feet although can be enlarged when appearing in adjunctive sites [4].…”
