Su frecuencia es extremadamente rara y existen escasos reportes en la literatura a nivel mundial. Se presenta un caso de un paciente con colapso avanzado del carpo producto de una no unión de escafoides no tratada. Se describen características clínicas y radiográficas del paciente y la resolución del caso con artrodesis total de muñeca.

Hajdu-Cheney syndrome is an uncommon skeletal disorder characterized by acroosteolysis and generalized osteoporosis. It is an extremely rare condition and few reports have been published in worldwide literature. We present a case of a patient with advanced carpal collapse product of a scaphoid non-union with Hajdu-Cheney syndrome. We describe clinical and radiographic characteristics and resolution of the case with total wrist arthrodesis.

Acroosteólisis en esclerosis sistémica / Acroosteolysis in systemic sclerosis

Paciente femenina de 42 años de edad, con diagnóstico de esclerosis sistémica de larga data. Clínicamente la paciente presentaba esclerosis cu-tis, fenómeno de Raynaud, calcinosis, enfermedad pulmonar intersticial y compromiso gastrointestinal dado por reflujo gastroesofágico. Consultó por dolor y deformidad en las falanges distales asociado a reabsorción del lecho ungular. A los rayos x se observó la desaparición tanto de la fa-lange distal como de los tejidos blandos circundantes .

Successful Treatment of Newly Developed, Intractable Digital Ulcers and Gangrene with Bosentan in Systemic Sclerosis

In systemic sclerosis, digital ulcers and gangrene are somewhat common clinical characteristics of obliterative vasculopathy. These manifestations increase morbidities, such as pain, infections, and acroosteolysis. However, patient responses to the appropriate treatments are often inadequate. We treated a patient with systemic sclerosis who had a refractory digital ulcer and gangrene with bosentan, an endothelin receptor antagonist, and observed improvement. Here we systematically review this case.

Pycnodysostosis with Multi-Segmental Spinal Canal Stenosis due to Ossification of the Yellow Ligament

Pycnodysostosis is an autosomal recessive disorder characterized by osteosclerosis, small stature, acro-osteolysis of the distal phalanges, loss of the mandibular angle, separated cranial sutures with open fontanels, and frequent fractures. One identified cause of the disease is reduced activity of the cysteine protease cathepsin K. A 48-year-old woman with a history of frequent fractures presented with a severe gait disturbance. Radiography, computed tomography, magnetic resonance imaging, and gene analysis were performed. Physical examination revealed open fontanels, and radiographs showed increased bone density. DNA sequence analysis revealed a deletion mutation of the cathepsin K gene. We diagnosed pycnodysostosis based on these findings. The magnetic resonance and computed tomography images demonstrated multilevel spinal canal stenosis due to ossification of the yellow ligament. We performed a laminectomy, and the patient's neurological signs and symptoms improved. To our knowledge, this is the first case of pycnodysostosis with ossification of the yellow ligament.

A Case of Acroosteolysis in Primary Hypertrophic Osteoarthropathy

Primary hypertrophic osteoarthropathy or pachydermoperiostosis is a rare hereditary disorder characterized by digital clubbing, pachydermia and periostosis. Its precise incidence and prevalence is still unknown due to the lack of controlled data. It occurs without any underlying causes and usually has a chronic course. Life expectancy may be of normal standards, but many patients develop multiple functional and cosmetic complications. So, it is important to diagnose this disease at an early stage and to treat the symptomat for the quality of life. We report a case of primary hypertrophic osteoarthropathy in a 68-year-old male with clinical features such as digital clubbing and pachydermia, radiographic findings of acroosteolysis and periosteal new bone formation.

Effect of Zoledronic Acid on Acro-Osteolysis and Osteoporosis in a Patient with Hajdu-Cheney Syndrome

Hajdu-Cheney syndrome is a rare, autosomal dominant skeletal dysplasia marked by acro-osteolysis of the distal phalanges and severe osteoporosis. Although there are more than 60 reports published to date, proper treatment and subsequent outcome have been scarce. Herein, we report a progress of anti-resorptive therapy with zoledronic acid, in a woman with Hajdu-Cheney syndrome. Results suggest that anti-resorptive therapy may be important in delaying the progress of osteoporosis and preventing fractures, but not necessarily acro-osteolysis itself.

Pyknodysostosis: report of a rare case with review of literature

Pyknodysostosis is a rare autosomal recessive disorder characterized by the post natal onset of short limbs, short stature, and generalized hyperostosis along with acro-osteolysis with sclerosis of the terminal phalanges, a feature that is considered essentially pathognomonic. Other features include persistence of fontanelles, delayed closure of sutures, wormian bones, absence of frontal sinuses, and obtuse mandibular gonial angle with relative mandibular prognathism. We report a case of 17-year-old girl who presented with a chief complaint of retention of deciduous teeth. General physical examination demonstrated short stature, frontal and parietal bossing, depressed nasal bridge, beaked nose, hypoplastic midface, wrinkled skin over the finger tips, and nail abnormalities. Radiographs showed multiple impacted permanent and supernumerary teeth, hypoplastic paranasal sinuses with acro-osteolysis of terminal phalanges, and open fontanelles, and sutures along with wormian bones in the lambdoidal region.

A Case Report of Hajdu-Cheney Syndrome

Hajdu-Cheney syndrome (HCS) is a rare skeletal dysplasia that is characterized by acroosteolysis of the distal phalanges, distinctive craniofacial and skull changes, dental abnormalities and generalized osteoporosis. The clinical and radiologic characteristics are variable and these characteristics progress with age. This syndrome shows autosomal dominant inheritance with sporadic cases. The genetic defects or molecular pathogenesis of HCS are still unknown. We experienced a case of Hajdu-Cheney syndrome in a 20-year-old man who had generalized osteoporosis with multiple non-traumatic spine compression fractures. He had acroosteolysis of the hands and feet, wormian bones in the skull, facial dysmorphism (mid-facial flattening, micrognathia and bushy eyebrows), a high arched palate, malocclusion and short dental alveolar processes. HCS was diagnosed based on the clinical and radiologic evidence. For the differential diagnosis, we excluded the other possible causes of the acroosteolysis and wormian bones, including hyperparathyroidism, osteogenesis imperfecta, hypophosphatemia and mandibuloacral dysplasia. The specific treatment of HCS is unknown, but case reports with bisphosphonate treatment have been reported.

Acroosteolysis of Scleroderma Associated with a Felon / 대한정형외과학회잡지

The Scleroderma is a chronic inflammatory disease of the connective tissue with involvement of the skin and other organs. It can be a manifestation of various disorders and occasionally acroosteolysis in the phalanges. Acroosteolysis is characterized by bone resorption or destruction in the phalanges, while the base is preserved. The pathogenesis of acroosteolysis in patients with scleroderma is a blood-flow disorder that is mainly associated with an abnormal accumulation of collagen in all tissues, microangiopathy and infections in the phalanges. The phalanges in patients with scleroderma are prone to continuous infections as a felon or skin ulcers due to atrophy of the subcutaneous tissue, dry and sclerotic skin, or a disorder of the immune system. We experienced a patient who had acroosteolysis with scleroderma of the phalanges, and this was associated with a felon. We report on this case along with a brief review of the literature.

A case of acro-osteolysis caused by peripheral neuropathy after minor burn injury / 대한내과학회지

Acro-osteolysis is characterized by bone resorption in the fingers and toes and can occur in several diseases. Occupational exposure to polyvinyl chloride polymers, thermal injury, and repetitive mechanical injury can also cause acro-osteolysis. The pathophysiology of the disease is unknown, but a unifying theme of vascular and mechanical injury is presented. Signs include Raynaud's phenomenon, bone loss in the hand and cold sensitivity. We report the case of a 67-year-old woman who presented with acro-osteolysis after being burned repeatedly.

Acrosteolisis severa en artritis gotosa y síndrome de Down / Severe acroosteolysis in gouty arthritis and Down syndrome

La asociación de gota y síndrome de Down (SD) es poco frecuente a pesar que ambas enfermedades son comunes en la población general. Más interesante aún es el hecho que la hiperuricemia sí es una característica frecuente entre las alteraciones metabólicas del SD. A continuación se informa el caso de un paciente de sexo masculino de 35 años con SD que consultó por artritis de tres años de evolución, inicial-mente en el quinto y luego en el primer dedo del pie izquierdo. Debido a la presencia de osteolisis severa en el primer y quinto dedo en la radiografía inicial del pie, se consideró patología tumoral, lo cual, sin embargo, fue descartado por ortopedia oncológica. Posteriormente se realizó el diagnóstico de artritis gotosa al encontrar hiperuricemia y confirmación de cristales de ácido úrico en una muestra de líquido extraída de un nódulo subcutáneo encontrado en el tobillo izquierdo. Este caso hace parte de los escasos informes que relacionan el SD y la gota. Adicionalmente el desarrollo de gota en este paciente tiene características inusuales como el sitio de inicio de la enfermedad y la severidad de la presentación. No es claro porque el desarrollo de gota en pacientes con SD es infrecuente.

The association between gout and Down Syndrome (DS) is very infrequent, in spite that both diseases are common in general population. Surprisingly, hyperuricemia is a common metabolic impairment in DS. In this report we describe a 35-years old man with DS presenting with arthritis in the fifth and then in the first toe of his left foot. Severe osteolysis of the first and fifth toe was seen by radiography. Because of this, neoplasm was suspected but later ruled out by oncologic orthopedist. After we found hyperuricemia a diagnosis of gout was made, and then confirmed by examination of a sample obtained from a subcutaneous node. This report is one of the few cases previously published. In addition, development of gout in this patient has unusual features like its onset in the fifth toe and its severity at presentation. In spite that hyperuricemia is common in DS, in not clear why these patients mostly do not develop gout.

Acro-osteolysis and mononeuritis multiplex as a presenting symptom of systemic angiitis of Wegener's type.

Wegener's granulomatosis is a multisystem disorder involving small- and medium-sized vessels, leading to granuloma formation and involvement of upper and lower respiratory tract with or without glomerulonephritis. However, limited forms of angiitis and granulomatosis of the Wegener's type with oligosymptomatic and atypical site involvement are known to occur. We present here a rare case of limited form of angiitis and granulomatosis of Wegener's type who presented sequentially with spontaneous resorption of digits with acro-osteolysis and mononeuritis multiplex over a period of 10 months. His vasculitic workup revealed high proteinase 3 antibodies (c-ANCA) titers and an almost asymptomatic lung involvement, detected on high-resolution computed tomography of chest. The patient was aggressively treated with immunosuppressive therapy, following which he showed good improvement.

Faun tail naevus: a cutaneous marker of spinal dysraphism.

We describe three cases (one male and two females) of faun tail nevi, which is one of the most important cutaneous marker of spinal dysraphism. One of the patients presented with acro-osteolysis leading to auto amputation of the toes of the left foot, which required operative intervention. This lays stress on the early recognition of lumbar paraspinal skin lesions and early treatment to avoid irreversible sequelae.

Pachydermoperiostosis in a 19 Year-old Boy Presenting as an Acromegaly-like Syndrome / 대한소아내분비학회지

A nineteen year-old boy with progressive enlargement of the joints and distal extremities, clubbing, coarse facial features and hyperhidrosis was investigated. In physical examination, thickening of the scalp with furrowing (cutis verticis gyrata) and greasy thickening of skin (pachyderma) was prominent. His endocrine profile was normal. Radiological studies demonstrated bilateral symmetrical periosteal new bone formation with acroosteolysis and incidental microadenoma of pituitay gland. After extensive investigation to exclude systemic and endocrine causes, the patient was diagnosed as pachydermoperiostosis (PDP). PDP is a rare syndrome manifested clinically by finger clubbing, extremity enlargement, hypertrophic skin changes, and periosteal bone formation. The pathogenesis of the disorder has not been clarified though few endocrine abnormalities were seen. To aware of these clinical phenotype would help to differentiate PDP from acromegaly.

Acrogeria / 대한피부과학회지

We report a case of a 41-year-old female with acrogeria. She was in good health except for the prominent atrophy over the hands and feet. On microscopic examination of a biopsy specimen from the atropl6c skin, elastic fibers were clumped and fragmented. Electronmicroscopy revealed amorphous and granulous pseudoelastin, which is presumed to be consistent with acrogeria. Our patient had acro-osteolysis and an extra chromosome in addition to the normal 23 pairs of chromosomes in one of 20 cells examined, which have been very rarely reported in the literature. Further studies are needed to find out whether this chromosomal aberration might contribute to the pathogenesis.

Bone and Joint changes following Electrical Burn: Plain Radiographic findings

PURPOSE: To evaluate the plain radiographic findings of bone and joint changes following electrical burn. MATERIALS AND METHODS: This study involved 19 patients with 27 bone and joints regions which had sufferedelectrical injury. The most common input and output sites were, respectively, the hand(7/14) and foot (6/10).Three other sites were involved. Four cases involved osteomyelitis, and in four, amputation was performed. Weobserved bone and joint changes, changes following osteomyelitis and changes in the amputation stump. We analyzedthe difference between input and output changes, and when this was interesting, the average time of onset wasassessed. RESULTS: In bone and joint changes following electrical burn, the most frequent radiographic findingwas joint contracture (n=16). Other findings included osteolysis (n=8), articular abnormalites (n=6), periostitis(n=5), fracture (n=5), acro-osteolysis (n=2), and heterotopic bone formation (n=2). In cases involvingosteomyelitis(n=4), aggravation of underlying bone changes was noted. CONCLUSION: In electrical burn, variouschanges were noted in bone and joints, and input injury was more severe than that of output.

A Case of Hereditary Sensory Neuropathy Type II with Acroosteolysis / 대한류마티스학회지

The hereditary sensory neuropathy is a very rare disease characterized by prominent sensory loss without corresponding motor involvement, but may be associated with autonomic features. Currently, the disease is divided into five main types and most frequent are Type I and Type II. The type II hereditary sensory neuropathy is characterized by autosomal recessive inheritance, onset in utero or in infancy, loss of touch-pressure sense more than paintemperature sense, and almost total absence of myelinated nerve fibers. In this case, we describe a 23 years old female patient with acroosteolysis and heel ulcer who was diagnosed as hereditary sensory neuropathy type II.

A Case of Sjogren Syndrome Associated with Acroosteolysis / 대한류마티스학회지

Acroosteolysis (AOL) refers to a destructive process involving distal phalangeal shaft while the tuft and base are preserved. It can be a manifestation of various diseases, such as scleroderma, Raynaud's disease, rheumatoid vasculitis, psoriasis, renal osteodystrophy and leprosy. Occupational exposure to polyvinyl chloride polymers, thermal injury, and repetitive mechanical injury can also cause this problem. Although the exact pathogenesis of AOL is uncertain, a unifying theme of vascular and mechanical injury is presented. Recently, we experienced a 32-year-old woman complained of xerophthalmia, zerostomia and polyarthralgia which was diagnosed as Sj6gren syndrome associated with acroosteolysis. After administration of prednisolone, cyclophosphamide and oral bromhexine, subsidence of her symptoms was observed. We report this case with a review of relevant literature.
