Calcifying aponeurotic fibroma (CAF) was originally described by Keasbey in 1953 as juvenile aponeurotic fibroma, most commonly occurring in the palms of the hands and soles of the feet in children and adolescents. It usually presents as a firm, painless mass without preceding trauma. We report a case of this rare condition with an unusual presentation in a 60-year-old woman affecting the dorsal surface of the foot. It is a relatively benign condition with a good prognosis following complete surgical excision. It may have a slightly increased incidence in males. The accurate diagnosis is based only on histology but it is essential to differentiate it from other sinister lesions such as fibrosarcoma that may lead to amputation.
Les auteurs rapportent l'observation d'un patient âgé de 56 ans qui consulte pour une tumeur du pied droit évoluant depuis 20 ans. L'examen retrouve une masse bourgeonnante, polyfistulisée, mesurant 10-20 cm et intéressant la face dorsale du pied et englobant la plante. La radiographie du pied retrouve une lyse osseuse des troisième, quatrième et cinquième métatarsiens. L'examen histologique retrouve un mycétome actinomycosique du pied. La lésion s'est compliquée d'une gangrène septique du pied qui a nécessité une amputation de celui-ci. Les mycétomes du pied sont des maladies infectieuses chroniques et endémiques dans les pays tropicaux. Ils sont rares dans notre contexte rendant le diagnostic difficile. Le traitement est médical, associé à une excision chirurgicale radicale des tissus atteints. Dans les cas évolués, ces lésions engagent le pronostic fonctionnel du membre et parfois le pronostic vital du patient. Pour citer cette revue : Méd. Chir. Pied 27 (2011).
Mots clés Tumeur · Mycétome · Actinomycose · Pied · AmputationAbstract Mycetoma is a rare andlittle-knownpathology in Morocco. The authors present the case of a56-year-oldpatient with a tumor of the right foot that had developed over 20 years. A pathological examination revealed an actinomycosic mycetoma of the foot. The injury was complicated by septic gangrene of the foot, requiring amputation. Mycetoma of the foot is a chronic and endemic infectious disease in tropical countries. However, it is rare in our context, making diagnosis difficult. The medical treatment involves radical surgical excision of diseased tissue. Mycetoma of the foot is a potentially fatal disease.
