A Rare Case Of Non Traumatic Myositis Ossificans Circumscripta.

INTRODUCTION: Myositis ossificans circumscripta is a benign non neoplastic ossifying tumor presenting with bone like osteoid tissue extraskelletaly amidst the muscle planes. This condition when not associated with trauma is very trivial and considering the way it mimics certain characteristics, it may be misunderstood as a malignant neoplasm, abscess or antibioma. The aetiology of this atraumatic condition is still indistinct and remains a question unsolved. We would like to report such a case with distinctly unusual presentation that occurred in our institute. Thereby help in understanding the characteristics of the tumor and associated problems in the diagnoses and treatment. CASE REPORT: We report a case of 18 year old male presenting with acute onset severe pain in right gluteal region and associated swelling with no history of trauma. All possible investigations including haematological work up, Radiographs, Ultrasonography, aspiration and Magnetic resonance imaging proved to be inconclusive. Open excision and histopathology revealed the condition as myositis ossificans. CONCLUSION: Our report is aimed towards understanding the difficulty in diagnosing atraumatic myositis ossificans circumscripta and aid in understanding the possible aetiology of unusual presentation without history of trauma.

Rare Case of Rhizomelic Chondrodysplasia Punctata.

INTRODUCTION: Rhizomelic chondrodysplasia punctata (RCDP) is a very rare disease. It impairs the normal development of many parts of the body. The features of this disorder include bony abnormalities, severe mental retardation, joint contractures, cataract and recurrent respiratory infections and breathing problems. Seizures and Distinctive facial features including prominent forehead, depressed nasal bridge and small nose is also associated with this pathology. Being rare, this is very difficult to diagnose when presented at OPD. Proper history and meticulous examination is extremely necessary. Our aim is to discuss current knowledge on etiopathogenesis as well as radiological and clinical symptoms of diseases associated with RCDP. CASE REPORT: 5 yrs old male child presented with chest infection and periarticular swelling of all the small and large joints. The patient was walking with limp. History elicited that the child was born of a consanguineous marriage. The child was delivered at home. Birth weight was 2.4 kgs. He repeatedly had upper respiratory tract infections and was taking treatment for the same. He was further investigated in the form of clinical, biochemical and radiological assessment which stated that the patient was suffering from RCDP. CONCLUSION: This is a rare presentation. Though this is not curable, management of RCDP is symptomatic and supportive and may include physiotherapy and orthopedic procedures (in later stages) to improve function. The child may also undergo cataract surgery to improve vision.
