[An unusual cause of tarsal tunnel syndrome in a 15-year-old girl: about a case]. / Cause inhabituelle de syndrome du canal tarsien chez une fille de 15 ans: à propos d'un cas.

Tarsal tunnel syndrome is a multifaceted condition caused by the compression or lesion of the posterior tibial nerve (PTN) that passes through a retromalleolar osteofibrous canal, the so-called tarsal tunnel. It has multiple etiologies, including peripheral nerve tumors, which must be suspected when this syndrome is resistant to medical treatment and infiltrations. We here report the original case of a 15-year-old girl presenting with tarsal tunnel syndrome revealing neurofibroma of the PTN, misdiagnosed as plantar fasciculitis and S1 radiculopathy.

[Genetic hypothesis involving Haglund's syndrome and its association with ankylosing spondylitis: case report]. / L'hypothèse génétique de la maladie de Haglund, et son association avec la spondyloarthrite ankylosante: à propos d'un cas.

Haglund´s syndrome is characterized by osterosuperior calcaneal exostosis which irritates the Achilles tendon and manifests mainly as posterior talalgia. We here report the case of a 28-year-old woman on follow up for ankylosing spondylitis. Her mother was on follow up for the same systemic disease, and one of her maternal aunts had undergone surgery due to Haglund's syndrome. Patient's delay led to incorrect diagnosis as talagia was considered by physicians as a consequence of her system disease. The patient did not improve under medical treatment. Surgery outcome was satisfactory. This study raises a hypothesis about the genetic and hereditary character of Haglund's syndrome and its relationship with treatment response.
