Post-traumatic myositis ossificans (PTMO) is characterised by abnormal heterotopic boneformation involving striated muscle. PTMO is usually associated with trauma and is most common in the second and third decades. An important teaching point is that in the early or subacute phase, clinical and imaging features can mimic a soft-tissue sarcoma. A combination of imaging modalities is required to evaluate the muscle lesion.

Limiting Condition

Myositis ossificans (MO) is a benign, self-limiting condition characterized by abnormal ossification of soft tissue. MO occurs most commonly in the setting of trauma, however can also develop spontaneously. A peripheral rim of zonal calcification within the affected region represents the classic late-stage appearance and is considered virtually pathognomonic. During the early stages of MO development, diagnostic uncertainty may, however, arise as its imaging features can demonstrate overlap with malignant lesions such as soft-tissue sarcoma. This may lead to unnecessary further investigations, including image-guided biopsy. Recognition of the imaging features of early MO using magnetic resonance imaging (MRI) can provide the radiologist with more diagnostic certainty and help obviate the need for unnecessary investigation of this benign entity. This case offers an example of how MRI can achieve this diagnosis during the early multimodality investigation of an indeterminate soft-tissue mass.

Storiform Pattern

Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue sarcoma characterized by the proliferation of spindle cells arranged in a storiform pattern. Here we report a case of DFSP presenting as a bluish-black atrophic plaque. The tumor had the histopathologic characteristics of both the pigmented and atrophic variants of DFSP. We describe the histopathologic, molecular, and imaging features of this patient and review other cases of DFSP that have been reported in the literature. Early identification of this DFSP variant can help clinicians implement clinical management strategies to prevent recurrence.

Post Traumatic

Myositis ossificans (MO) is a benign bone formation in an extra-skeletal location. The most common subtype of MO, the post-traumatic, usually develops in young males after a traumatic event or sports injury. MO may simulate malignant bone lesions such as extra-skeletal or surface osteosarcomas, or soft tissue sarcomas such as synovial sarcoma or undifferentiated pleomorphic sarcoma. In the early phase the diagnosis of MO is challenging because imaging and histopathological findings may be non-characteristic. Detailed medical history as well as clinical examination, follow-up imaging studies and histological assessment are crucial for a proper diagnosis. Early and accurate differential diagnosis between MO and malignant soft tissue and bone tumours is important to maximize. Cite this article: EFORT Open Rev 2021;6:572-583.

A new virus, established as a member of the herpesvirus group by electron microscopy, was isolated from spontaneously degenerating cell cultures derived from the kidneys and lungs of two normal tree shrews. The virus was found to replicate best in cells derived from the homologous species. The cells used were a tree shrew cell line, T-23, which was derived from a spontaneous soft tissue sarcoma. The virus did not multiply or did so poorly for a limited number of passages in human, monkey, rodent, rabbit or chick embryo cells. In the T-23 cells, the virus behaved as members of the subgroup B of herpesvirus, in that the virus remained primarily cell associated.
