[Plantar fibromatosis and Dupuytren's contracture in an adolescent]

Fibromatosis represents a wide group of benign, locally proliferative disorders of fibroblasts. Dupuytren's disease is a benign proliferative disease of palmar aponeurosis which usually affects adults between 40 and 60 years of age. Ledderhose's disease or plantar fibromatosis is plantar equivalent of Dupuyten's disease most often affecting middle-aged and older men, usually bilateral, represented with painless nodule in the medial division of plantar fascia.

We presented a 19-year old adolescent that turned to a plastic surgeon complaining to his small finger contracture. He noticed palmar thickening with nodule over the metacarpophalangeal joint of small finger of his right hand when he was 16 years old. A year later a finger started to band. During physical checkup we noticed plantar nodule that also had his father and grandmother. Magnetic resonance and tumor biopsy confirmed a suspicion on plantar fibromatosis - Ledderhose's disease. Clinical exam of the hand clearly led to a conclusion that the patient had Dupuytren's contracture with pretendinous cord over the small finger flexor tendons and lack of extension of proximal interphalangeal (PIP) joint. On the extensor side of the PIP joints there were Garrod's nodes. The patient refused surgical treatment of plantar tumor, but agreed to surgical correction of finger contracture.

Despite the fact that Dupuytren's disease and plantar fibromatosis are diseases of adults, the possibility of conjoint appearance of these forms of fibromatosis in adolescent period of life should be kept in mind especially in patients with strong genetic predisposition.
