Varón joven con paquidermodactilia: hallazgos radiológicos / Young male with pachydermodactyly: imaging findings

La paquidermodactilia (PDD) es una forma rara y benigna de fibromatosis digital. Se caracteriza por un engrosamiento asintomático de los tejidos blandos en las caras laterales de las articulaciones interfalángicas proximales de las manos y a veces puede confundirse con algunas enfermedades reumáticas. Los cambios visibles en la resonancia magnética no han sido descritos hasta ahora en la bibliografía médica. Presentamos un caso de PDD en un varón de 19 años y describimos los hallazgos radiológicos en la radiografía simple y en la resonancia magnética. Asimismo, se discute brevemente la PDD(AU)

Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis characterized by an asymptomatic soft-tissue swelling affecting the skin of the lateral aspects of the proximal interphalangeal joints of the fingers, and sometimes can be misdiagnosed with some rheumatic conditions. Magnetic resonance images changes have not been described in any of the case reports in the literature. We report here a case of PDD in a 19-year-old male and we describe its findings on X-ray and magnetic resonance images. We briefly discuss PDD(AU)

Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis characterized by an asymptomatic soft-tissue swelling affecting the skin of the lateral spects of the proximal interphalangeal joints of the fingers, and sometimes can be misdiagnosed with some rheumatic conditions. Magnetic resonance images changes have not been described in any of the case reports in the literature. We report here a case of PDD in a 19-year-old male and we describe its findings on X-ray and magnetic resonance images. We briefly discuss PDD.

Muscle pathology in ankylosing spondylitis: clinical, enzymatic, electromyographic and histologic correlation.

We assessed muscle pathology in 30 patients with ankylosing spondylitis (AS) and 22 controls to assess if skeletal muscle is affected primarily by the inflammatory process of the disease. Investigations included a questionnaire on musculoskeletal discomfort, physical exercises, dynamometric measurements, EMG, and biopsy of the quadriceps muscle. Symptoms of muscular weakness were related with enthesopathic activity index. Plasma CK was higher in patients than in controls. A myopathic EMG pattern was found in 46.4% patients. Histological changes were found in 66% and did not correlate with symptomatology. Patients with AS with clinical muscular manifestations probably have intense enthesopathic inflammatory activity. It is suggested that muscles are secondarily affected as a consequence of pain inhibition and reduced activity.
