    This 3D model represents a case of high grade leiomyosarcoma implicating the left groin region of a 24 years old female. The patient was treated by surgical excision follower by chemotherapy as well as radiotherapy. A cross sectional CT image is attached showing the lesion in axial, coronal and sagittal planes. Leiomyosarcoma (LMS) is a very rare malignant neoplasm that arises from smooth muscle cells and is considered to be the malignant extension of leiomyoma. Leiomyosarcoma is classified under soft tissue tumours and represents around 8% of all soft tissue malignant tumours. Common locations affected by leiomyosarcoma are: the uterus, retroperitoneum, stomach, oesophagus, small intestine and generally anywhere with smooth muscles. Leiomyosarcoma appears heterogeneous in CT with common central attenuation representing necrosis.

    This 3D model represents a case of high grade extraskeletal osteosarcoma affecting the left adductor muscle of a 27 years old male. The patient was treated by surgical excision follower by chemotherapy. A cross sectional CT image is attached showing the lesion in axial, coronal and sagittal planes. Extraskeletal osteosarcoma (ESOS) is one of the rare malignant neoplasms that affects the mesenchymal tissues such as the retroperitoneum as well as the soft tissue of the extremities with no significant connection to the related bones. Extraskeletal osteosarcoma usually affects people between 40 years and 80 years and is more common in males with a documented risk factor which is radiation exposure. The common presentation is enlarged or swollen soft tissue which could be painful or not. Extraskeletal osteosarcoma is diagnosed by plain x-ray, CT or MRI as the soft tissue shows variable calcification. The most common affected sites are the lower extremities followed by upper extremities and retroperitoneum. Most of patients are presented with metastasis at time of diagnosis which leads to a generally poor prognosis. The usual treatment is surgical excision of the primary tumor as the tumor is insensitive to chemotherapy or radiotherapy. This 3D model was created from the file STS_045. The source scan can be found here.

    This model is the bilateral thigh muscle rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient unfortunately died 9.5 months after diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. Myxoid fibrosarcoma (or myxoid MFH) is the most common subtype of MFH, at about 10%-20% of cases. Clinically, the tumor presents as a deep, slow-growing, painless mass. It is located more commonly in the lower extremities and retroperitoneum. Imaging on MRI demonstrates a mass with low signal intensity on T1-weighting imaging, and high signal intensity on T2-weighted imaging. On histology, a myxoid background is present with a storiform (or cartwheel) pattern seen on low-power imaging, seen in fibrosarcomas. A “myxoid background” is composed of a clear, mucoid substance. Treatment includes radiation, wide surgical resection, and chemotherapy in selected cases. However, the 5-year survival is 50%-60% depending on size, grade, depth and presence of metastasis. The term “malignant fibrous histiocytoma” was coined in the 1960s by Margaret R. Murray when histology a sarcoma demonstrated an appearance like histiocytes, with characteristics of phagocytosis and a pleomorphic pattern. With further research, this entity was identified to have a wider range of appearances with a fibrous characteristic. Today, these sarcomas are known as “pleomorphic sarcomas.” Recently, a change in the understanding of soft tissue tumors has purported that MFH is not a specific type of cancer, but a common morphologic pattern shared by unrelated tumors. One school of thought states that this morphologic pattern is shared by tumors as a common final pathway in cancer progression whereas another school of thought believes that true pleomorphic sarcomas are the result of a transformation from mesenchymal stem cells. Future research into understanding the pathway of these sarcomas and progression will help to target specific therapies and, hopefully, eventual cures. This model was created from the file STS_023.

    This model is the right foot and ankle muscle rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient unfortunately died 9.5 months after diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. The primary motions of the ankle are dorsiflexion, plantarflexion, inversion and eversion. However with the addition of midfoot motion (adduction, and abduction), the foot may supinate (inversion and adduction) or pronate (eversion and abduction). In order to accomplish these motions, muscles outside of the foot (extrinsic) and muscles within the foot (intrinsic) attach throughout the foot, crossing one or more joints. Laterally, the peroneus brevis and tertius attach on the proximal fifth metatarsal to evert the foot. The peroneus longus courses under the cuboid to attach on the plantar surface of the first metatarsal, acting as the primary plantarflexor of the first ray and, secondarily, the foot. Together, these muscles also assist in stabilizing the ankle for patients with deficient lateral ankle ligaments from chronic sprains. Medially, the posterior tibialis inserts on the plantar aspect of the navicular cuneiforms and metatarsal bases, acting primarily to invert the foot and secondarily to plantarflex the foot. The flexor hallucis longus inserts on the base of the distal phalanx of the great toe to plantarflex the great toe, and the flexor digitorum inserts on the bases of the distal phalanges of the lesser four toes, acting to plantarflex the toes. The gastrocnemius inserts on the calcaneus as the Achilles tendon and plantarflexes the foot. Anteriorly, the tibialis anterior inserts on the dorsal medial cuneiform and plantar aspect of the first metatarsal base as the primary ankle dorsiflexor and secondary inverter. The Extensor hallucis longus and extensor digitorum longus insert on the dorsal aspect of the base of the distal phalanges to dorsiflex the great toe and lesser toes, respectively. This model was created from the file STS_023.
