ABSTRACT
Paciente de 22 años con rigidez congénita de miembro superior izquierdo y hallazgos en angio TAC de pseudocoartación aórtica y aneurismas a varios niveles (aorta ascendente, cayado aórtico, arteria mesentérica superior, mesentérica inferior, renales segmentarias, aorta abdominal y arteria hipogástrica izquierda). Presenta imagen en "gota de cera" en radiografía de pelvis y en angio RM destacan lesiones esclerosas poliostóticas y malformación arteriovenosa en partes blandas de cadera izquierda. No se realiza estudio genético por la negativa del paciente

PURPOSE: Melorheostosis is a progressive hyperostotic bone disease that commonly affects the appendicular skeleton. Melorheostosis has a significant degree of overlap with other hyperostosis conditions including osteopoikilosis and likely represent varying degrees of a clinical spectrum. METHODS: This is a report of 2 patients with melorheostosis who presented with different clinical presentations and involvement of different anatomic locations. RESULTS: One of the patients presented with foot size asymmetry along with intermittent foot pain and limping. This patient also had irregular nonblanching yellow plaque-like lesion on the forehead. The second patient presented with abnormal gait but no pain. Radiographs demonstrated endosteal hyperostosis, which were consistent with a mixed picture of melorheostosis and osteopoikilois. Genetic testing of the LEMD3 gene from a blood sample was negative in both cases. CONCLUSIONS: The diagnosis of melorheostosis can be made based on the clinical and radiographic features and can be challenging to differentiate from other hyperostosis conditions. LEVEL OF EVIDENCE: Level V.

La melorreostosis es una rara displasia ósea benigna esclerosante.Su etiología es desconocida y ambos sexos pueden verse afectados. Los huesos largos de las extremidades inferiores y los tejidos blandos adyacentes son los más frecuentementeinvolucrados. La enfermedad se presenta raramente en los miembros superiores y se han comunicado muy pocos casos localizados en la mano. Comunicamos el caso de una niña de 7años de edad que presenta características típicas de melorreostosisen la mano derecha. El diagnóstico se realizó mediante radiografía convencional y gammagrafía ósea. La resonancia magnética contribuyó a la evaluación de las lesiones en partesblandas. El tratamiento médico permitió aliviar el dolor y mejorar la movilidad. Como la melorreostosis tiene una tendencia variable hacia la progresión de las lesiones y asociación conpatologías tumorales, se recomienda un estricto control periódicode estos pacientes.
Melorheostosis is a rare benign sclerosing bone dysplasia. Its etiology is unknown. Both sexes can be affected. Sites most frequently involved are the long bones of the lower limbs andthe adjacent soft tissue structures. The disease is unusual in the upper limbs, and few cases have been reported in the hand. We report the case of a 7-year-old girl who had typical featuresof melorheostosis in the right hand. Diagnosis was made by conventional radiography and bone scintigraphy. Magnetic resonance contributed to the assessment of soft tissue lesions.Medical treatment allowed pain relief and range of motion improvement. Because melorheostosis has a variable tendency towards progression and association with tumors, a close follow-up of these patients is recommended.

Melorheostosis is a non-hereditary disorder involving the bones in a segmental pattern, whereas osteopoikilosis is a rather mild disseminated bone disorder inherited as an autosomal dominant trait. Interestingly, melorheostosis and osteopoikilosis may sometimes occur together. In analogy to various autosomal dominant skin disorders for which a type 2 segmental manifestation has been postulated, melorheostosis may be best explained in such cases as a type 2 segmental osteopoikilosis, resulting from early loss of the corresponding wild type allele at the gene locus of this autosomal dominant bone disorder.

We report a case of mixed sclerosing bone dysplasia in a 26-year-old man. This is a very rare disorder characterized by a variable combination of melorheostosis, osteopoikilosis and osteopathia striata. The disease may be generalized or may show unilateral involvement.

La melorreostosis es una enfermedad poco común, se describió desde 1933, su etiología es poco precisa aun cuando se cree que es de origen genético con defectos en la capa mesodérmica. Se describe el caso de una niña diagnosticada y tratada en el Hospital Shriners. En esta patología se observa, a nivel óseo, el engrosamiento de la cortical y según su extensión, en los huesos de todo un miembro o en una porción de un solo hueso producirá una deformación total o parcial del miembro

Melorheostosis is an unusual sclerotic dysplasia of bone. We describe a patient with melorheostosis who showed improvement in pain and vasomotor function after treatment with nifedipine. Peripheral vascular disturbances may be responsible for the pain associated with this disorder and vascular abnormalities could possibly be related to the pathogenesis of this disease.
