Aneiros-Fernandez J, Caba-Molina M, Arias-Santiago S, Ovalle F, Hernandez-Cortes P, Aneiros-Cachaza J - J Clin Med Res (2010)

Bottom Line: We describe a rare case of calcifying of myositis ossificans not associated to trauma in a 35-year-old woman with a mass in her upper third and external of right thigh.We discuss some of the difficulties of diagnosis and histological evolution of the lesion.Myositis ossificans; Thigh; Differential diagnosis; Nontraumatic.

ABSTRACT

Unlabelled: Myositis ossificans circumscripta is a form of heterotopic ossification that is benign in nature associated to a trauma, but may appear clinically and radiologically as a malignant neoplasm. We describe a rare case of calcifying of myositis ossificans not associated to trauma in a 35-year-old woman with a mass in her upper third and external of right thigh. We discuss some of the difficulties of diagnosis and histological evolution of the lesion.

Keywords: Myositis ossificans; Thigh; Differential diagnosis; Nontraumatic.

Figure 2: Echography revealed heterogeneous echogenicity with some calcification within it.

Mentions: A 35-year-old caucasic woman, no previous personal or family history of interest, visited our hospital and presented upper third and external of right thigh mass. On physical examination, a slightly tender, hard, not well-circunscribed mass was palpated in the external of right thigh. She denied any previous history trauma including exercise-related trauma. The laboratory findings were normal. Computed tomography of the thigh showed a 42 × 27 mm mass. A faint calcification was noted in the peripheral area of the mass. Bone gammagraphy presented intense uptake in soft tissue with central area low uptake (Fig. 1). Echography revealed heterogeneous echogenicity with some calcification within it (Fig. 2). Histological showed three zones: (1) centre zone presented proliferating fibroblasts with areas of haemorrhage; (2) intermediate zone was characterized by osteoblasts with immature osteoid formation and islands of cartilage; (3) peripheral zone was composed of mature bone surrounding tissue by fibrous and muscle tissue (Fig. 3, 44).
