Myositis ossificans is delineated and distinguished by the generation and deposition of cartilaginous and osseous soft tissues. It generally occurs in the lower extremities and is caused by direct trauma. During the different developmental stages of maturation, the lesion has different radiological appearances that can be confused with sarcomas. Here, we present the case of a 38-year-old woman who presented to the outpatient clinic with a painful mass in the lateral chest wall that had rapidly expanded and increased in size...

BACKGROUND: The aim of this study was to assess the clinical and radiographic outcomes of cubitus varus treatments based on different fixation methods: Locking plate vs. Kirschner-wires (K-wires) and cast fixation. METHODS: This retrospective study of 28 patients was performed in lateral-wedge osteotomy for cubitus varus deformity in our hospital from July 2018 to July 2020. 14 patients in group A were treated by locking plate after lateral closing-wedge osteotomy, whereas other 14 patients were treated by K-wires in group B...

Fibro-osseous pseudotumor of the digits is a benign tumour closely related to myositis ossificans. It is a rare lesion seldom reported in the literature. We report the case of a 33-year-old woman with lancinating pain in the first phalanx of the second finger of the right hand, associated with inflammation. The histopathological examination of the surgical excision biopsy of the lesion revealed a spindle-shaped proliferation within a sclerosing, hyaline, and osteoid stroma. In our observation, immunohistochemistry and molecular biology are the main elements that helped to establish the diagnosis and eliminate the various differential diagnoses, despite a non-specific histopathological aspect...

Fibrodysplasia ossificans progressiva (FOP) is an autosomal dominant disorder characterized by congenital deformities of the big toes and the progressive formation of extra-skeletal bone within soft tissues. The underlying genetic cause of FOP is mostly due to gain-of-function mutations in the AVCR1/ALK2 genes. These mutations cause aberrant bone morphogenetic protein (BMP) signaling pathways and eventually result in cumulative musculoskeletal impairment. FOP has a prevalence of approximately one in every 2 million people worldwide, with nearly 90% of patients being misdiagnosed, possibly leading to an underestimation of its true prevalence...

INTRODUCTION: Bony subungual growths arising on the digital tip are uncommon. Among these, subungual exostosis is a common cause. CASE PRESENTATION: We describe a 35-year-old-male patient with a rare occurrence of a fibro-osseus pseudotumor of the digit. It presents with reactive intramembranous ossification, with no continuity with the distal phalanx, helping differentiate it from a subungual exostosis. The patient presented with an asymptomatic subungual growth, lifting up the nail plate distally causing onycholysis...

Flexion-type pediatric humeral supracondylar fractures are rare, and the reduction technique remains contradictory. A minimally invasive technique using percutaneous leverage reduction combined with an external fixator was described to achieve satisfactory reduction and avoid the open reduction in this study. The operation and clinical results of patients treated with this technique were retrospectively compared with traditional closed reduction. From January 2013 to January 2018, children diagnosed with displaced flexion-type humeral supracondylar fractures were included in this study...

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) as a rare and heritable disorder with the infrequent genetic transmission of the condition is a catastrophic disorder of heterotopic ossification (HO) and a cause of extraskeletal bone formation in humans. Given the lack of effective treatment for this disease, the important point is to avoid aggravating factors such as bone biopsy, surgery, and intramuscular injection. CASE PRESENTATION: In this report, we present a 52-year-old female patient, Kurdish ethnic, suspected to FOP who had a surgical intervention on the second toe of the right foot, which subsequently, it caused further deterioration of the disease in the person including necrosis and amputation of the distal phalanx of the second toe...

BACKGROUND: Ossified intramuscular hematomas (OIH) are an exceptionally rare condition that may be mistaken for alternative calcified intramuscular pathologies, such as myositis ossificans. Exceedingly few cases of OIHs have been reported to date, with no cases yet to be reported in the paraspinal muscles. CASE PRESENTATION: Here, we report on a patient who presented with a chronic back pain and swelling in the setting of trauma 15 years prior. Radiographic workup revealed a calcified mass in the erector spinae muscles...

Aneurysmal bone cyst (ABC) is a rare and usually painful condition, representing about 1% of all bone tumors. A geographical lytic, expansile, and septated radiological pattern, with fluid-fluid levels on MRI, is classically displayed. ABC can be a primary bone lesion (70% of patients) or can arise in an underlying condition and is subsequently named "ABC-like changes" (30%). ABC-like changes are more frequently encountered in skeletal segments affected by chondroblastoma, fibrous dysplasia, giant cell tumor, osteoblastoma, non-ossifying fibroma, and osteosarcoma...

Fibrodysplasia ossificans progressiva is a rare hereditary disorder characterized by progressive heterotopic ossification in muscle and connective tissue, with few reported cases affecting the head and neck region. Although plain radiographic findings and computed tomography features have been well documented, limited reports exist on magnetic resonance findings. This report presents 2 cases of fibrodysplasia ossificans progressiva, one with limited mouth opening due to heterotopic ossification of the lateral pterygoid muscle and the other with restricted neck movement due to heterotopic ossification of the platysma muscle...

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) is a very rare, severe genetic disorder triggered by a gain-of-function mutation in the ACVR1 gene that codes for the type I bone morphogenetic protein (BMP) receptor ACVR1 (activin A receptor-type 1), also known as ALK2 (activin receptor-like kinase-2). It leads to the onset and progression of heterotopic ossification (HO) in soft and connective tissue. HO is often preceded by episodes of soft tissue swelling or flare-ups...

Myositis ossificans of the temporalis muscle results in a cosmetic problem both before and after treatment because of the preoperative swelling and the postoperative defect respectively. The authors hypothesized that a patient-specific Polyether-ether ketone implant can be appropriate for immediate obliteration and reconstruction of such defect benefiting from the accuracy of CAD/CAM technology and computer-guided maxillofacial surgery. A Forty-year-old male patient with myositis ossificans affecting the left temporalis muscle was treated with a computer-guided surgical approach, a patient-specific implant was fabricated to obliterate the defect and avoid temporal hollowing using PEEK material...

Myositis ossificans (MO) is an uncommon tumor characterized by a rapidly growing mass following a history of local trauma. Few cases of MO affecting the breast have been reported, and some were misdiagnosed as primary osteosarcoma of the breast or metaplastic breast carcinoma. The following case report presents a patient with a growing breast lump whose core biopsy result was suspicious for breast cancer. MO was diagnosed after analysis of the mastectomy specimen. This case highlights the importance of MO as a differential diagnosis of a growing soft-tissue mass after trauma to avoid unnecessary overtreatment...

Bizarre parosteal osteochondromatous proliferation (BPOP) is a surface-based bone lesion belonging to the group of benign chondrogenic tumors. The aim of this review is to familiarize the readers with imaging features and differential diagnosis of BPOP, also addressing pathological presentation and treatment options. The peak of incidence of BPOP is in the third and fourth decades of life, although it can occur at any age. Hands are the most common location of BPOP (55%), followed by feet (15%) and long bones (25%)...
