Melorheostosis of the hand

Melorheostosis of upper limb: A report of four rare cases

Melorheostosis is a rare chronic bone disease, etiology of which remains unclear. It mostly affects lower limbs and clinical features vary in each case. Radiographs show characteristic "candle wax pattern" of hyperostosis. Herein we report four cases of upper limb affection with their symptoms, radiographic findings and treatment. First case presented with gradually progressive swelling in forearm which was initially misdiagnosed as filariasis. Plain radiograph eventually demonstrated melorheostosis of ulna. Second patient had deformity of index finger and pain in hand which was diagnosed on radiograph of hand. Third case presented with progressive flexion deformity of ring and little finger. Fourth patient had ulnar involvement which was an incidental diagnosis. First three patients were managed with bisphosphonates following which there was significant improvement in pain and fourth case was kept on follow-up as he was asymptomatic.

A rare case of melorheostosis of the hand in a pediatric patient

Melorheostosis, a rare mesenchymal dysplasia of bone, generally affects about 0.001% of people globally with about 400 cases total being reported. Melorheostosis of the hand, especially in the pediatric population, has been seldom reported. Previous studies have investigated potential genetic mutations associated with melorheostosis however, questions still remain regarding effective treatment options for this disease. This case report describes a unique case of pediatric melorheostosis of the hand and further clarifies current theories on melorheostosis with regards to pathogenesis, best treatment practices, and future research.

Melorheostosis of the thumb and trapezium bone

Melorheostosis of the hand is rare. We report a 28-year-old woman with persistent pain associated with a slowly growing mass on the dorsum of the right thumb. The radiographs, computed tomography, and magnetic resonance imaging were used to examine characteristic of melorheostosis involving the trapezium bone, first metacarpal, and proximal phalange. The lesions underwent a surgical debulking of the hyperostotic cortex and a cortical fenestration.

Case report: Emergency department diagnosis of melorheostosis in the upper extremity: a rare disease with an unusual presentation

BACKGROUND

Melorheostosis is a rare disease that affects fewer than 1:1,000,000 persons worldwide and most typically affects the lower extremities. It is a non-hereditary disease that may be debilitating due to chronic pain, contractures of the soft tissue, and even shortening of the affected limbs. Although it most commonly occurs in the lower extremities, melorheostosis has been reported in various locations throughout the body.

OBJECTIVE

This case report describes a patient who presented to the Emergency Department (ED) with this rare disease in an uncommonly affected bone.

CASE REPORT

The patient was a 21-year-old man who presented to the ED with pain in his left upper extremity that he attributed to playing sports 3 days before presentation. Plain films revealed periosteal hyperostosis typical of melorheostosis in several of his carpals, metacarpals, and phalanges, as well as the humerus and ulna. The patient was discharged with orthopedic follow-up and pain medication.

CONCLUSION

Melorheostosis is a rare disease that has characteristic radiographic findings likened to the appearance of melting wax flowing down the side of a candle. In certain cases, the disease can be debilitating and may require chronic pain management and even operative intervention. If this diagnosis is made in the ED, the emergency physician should provide adequate pain management and refer the patient to an orthopedic specialist for a work-up to rule out other sclerosing bone dysplasias.

Melorheostosis: clinicopathological features, diagnosis, and management

Melorheostosis is a rare sclerosing bone disease. This article describes the histological patterns and radiographic characteristics commonly associated with melorheostosis. A paucity of compiled data about the disease in the literature necessitated a comprehensive review to further define its management.

Non-malignant fibrosing tumors in the pediatric hand: a clinicopathologic case review

Non-malignant fibrosing tumors in the pediatric hand or juvenile fibromatoses are clinically challenging because of their relatively infrequent occurrence and because of the variety of names associated with these diseases. We conducted a review of a personal case series of pediatric patients with these tumors and discuss here the more common histologic types and clinical characteristics of the disease spectrum in the context of the available published literature. All histologic samples were reviewed by a single pathologist. Infantile myofibromatosis, fibrous hamartoma of infancy, juvenile aponeurotic fibromatosis, palmar fibromatosis (Dupuytren's type), infantile digital fibromatosis (Reye's tumor), fibroma of the tendon sheath, and melorheostosis represent the encountered lesions.

[(Over-)flowing bone: the rare disease of melorheostosis: clinical presentation and therapeutic concepts demonstrated by three cases]

Melorheostosis is a rare, benign, and sporadically occurring osteosclerosis of unknown cause. The onset of the disease is usually in early adulthood. Melorheostosis affects both genders, develops progressively, and is usually limited to one side of the human body. The sclerosis originates predominantly from the cortices of the long bones of the lower limbs and rarely the upper limbs. Frequently, the sclerosis involves the soft tissue surrounding the affected bones which may cause limitations in the range of motion, contractures, deformities, and pain. Melorheostosis is usually diagnosed by radiograms. Pain relief and restoration of the full range of motion are the primary goals of the therapeutic approach. A good outcome cannot always be achieved and a recurrence of the disease happens very often.

Surface lesions of the bones of the hand

Surface lesions involving the bones of the hand are uncommon. This pictorial review illustrates the spectrum of conditions including benign primary bone tumours, malignant primary bone tumours and non-neoplastic disorders. The review focuses on the radiographic appearances of these lesions and other techniques such as CT and MR imaging that may suggest a specific diagnosis.

Melorheostosis: unusual presentation in a girl

Melorheostosis is a rare bone disease of unknown etiology. It is characterized by tense and erythematous skin, contractures and shortening of the affected limbs. Radiographs reveal hyperostosis in long bones resembling melting wax, and spotty or patchy endostic deposits in short bones. An 11-year-old girl showed, since birth, contractural deformities in the right hand without bone abnormalities. At the age of 12 months, she complained of soft tissue tightness in the right buttock. At 3 years, limitation of flexion and extension of the right knee was evident. Radiographs revealed findings typical of melorheostosis.
