1/200. Intramuscular mixed tumour with clonal chromosomal changes.

    A case of an entirely intramuscular mixed tumour occurred in an 82-year-old man, who presented with a large mass in the region of the right triceps muscle. A lobulated tumour was seen, with plump, round epithelioid cells embedded in a chondromyxoid stroma. Immunohistochemical examination showed strong S100 protein and pancytokeratin positivity in most of the tumour cells. cytogenetic analysis revealed complex clonal chromosomal changes: 47, XY, i(2) (q10), -15, der(17) t(15; 17) (q11; p12), r. Differential diagnosis against extraskeletal myxoid chondrosarcoma (EMC) may be problematic, particularly in an incisional biopsy. Chromosomal analysis can be very helpful in solving this problem, since EMC shows a specific reciprocal chromosome translocation characterised as t (9;22) (q22-31) (q11-12).

2/200. Diffuse metastatic infiltration of a carcinoma into skeletal muscle.

    Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report a patient with rapidly progressive contractures due to metastatic infiltration of a carcinoma of unknown origin into the skeletal muscle. This 61-year-old man presented with a 1-month history of rapidly evolving, painful restriction of mobility of his right arm and his legs. Computed tomography showed diffuse metastatic nodules in all muscles, particularly in the hip abductors. Muscle biopsy revealed extensive infiltration of the muscle with carcinoma cells.

3/200. leiomyosarcoma of the diaphragm.

    An asymptomatic, intrathoracic mass was found on imaging studies in a 53-year-old man. After excision it proved to be an extrapulmonary leiomyosarcoma, a rare malignancy of smooth muscle, originating from the right diaphragm. The location of this malignant tumor is rare in an adult. The tumor was resected, the diaphragm was reconstructed, and the patient should have a long-term cure and good quality of life.

4/200. Fibrous dysplasia with intramuscular myxoma (Mazabraud's syndrome). Report of a case and review of the literature.

    About 30 cases of fibrous dysplasia associated with one or more myxomas (Mazabraud's syndrome) have been reported since 1926. We report a new case in a woman with polyostotic fibrous dysplasia and a myxoma in the left femoral muscle. She also had a history of precocious sexual development and cafe au lait spots, two manifestations whose association with polyostotic fibrous dysplasia defines McCune-Albright syndrome.

5/200. Primary anaplastic large cell lymphoma of skeletal muscle presenting with compartment syndrome.

    We describe a patient with primary anaplastic large cell lymphoma of the forearm presenting with compartment syndrome. Urgent decompression fasciotomy and combination chemotherapy resulted in durable remission status. This is followed by a review of primary skeletal muscle lymphoma in the English literature.

6/200. Intramuscular solitary fibrous tumor: a clinicopathological case study.

    We present a case of extrapleural solitary fibrous tumor arising within the muscle, an unusual and hitherto-undescribed tumor lesion. A 42-year-old woman presented a painless mass in her left thigh. The lesion was depicted as an intramuscular mass that enhanced on both CT and MRI, showing quite rich tumor vascularity. The histological features of the tumor were spindle cell proliferation with various histological patterns, typical fibrocollagenous background, and positive immunoreactivity for CD-34.

7/200. A case of congenital multiple myofibromatosis developing in an infant.

    BACKGROUND: Infantile myofibromatosis is marked by the development of firm, discrete, flesh-colored to purple nodules in skin, muscle, bone, and/or subcutaneous tissues. In cases without visceral involvement, the prognosis is excellent with expected spontaneous regression of nodules in 1 to 2 years. Visceral lesions are associated with significant morbidity and mortality generally within the first few months of life secondary to obstruction of a vital organ, failure to thrive, or infection. observation: We present a case of congenital myofibromatosis initially presenting as a single, asymptomatic nodule on the midback of an otherwise healthy 1-month-old white boy. Over the subsequent 6 months, the child developed a left-sided head tilt with the formation of additional myofibromas of the skin and musculature, but without visceral involvement. Physical examinations have continued to show age-appropriate growth and development. CONCLUSION: Clinicians should be aware of this rare but potentially life-threatening entity and consider infantile myofibromatosis in the differential diagnosis of pediatric dermal and subcutaneous nodules, particularly when associated with a new onset of head tilt. Close clinical follow-up is recommended in all cases of infantile myofibromatosis.

8/200. Osteogenic sarcoma with skeletal muscle metastases.

    Two cases of osteogenic sarcoma with skeletal muscle metastases are described. A 40-year-old woman presented with progressive swelling of both calves and a soft tissue back lump. She had been diagnosed with mandibular chondroblastic osteogenic sarcoma 6 years earlier. Radiographs showed calcified masses. MRI scans and bone scintigraphy revealed multiple soft tissue masses in both calves. Bone scintigraphy also showed uptake in the back lump, right thigh and left lung base. biopsy confirmed metastatic chondroblastic osteogenic sarcoma, which initially responded well to chemotherapy. However, the metastatic disease subsequently progressed rapidly and she died 21 months after presentation. The second case concerns a 20-year-old man who presented with a pathologic fracture of the humerus, which was found to be due to osteoblastic osteogenic sarcoma. He developed cerebral metastases 17 months later, followed by metastases at other sites. Calcified masses were subsequently seen on radiographs of the abdomen and chest. CT scans confirmed the presence of densely calcified muscle metastases in the abdominal wall, erector spinae and gluteal muscles. The patient's disease progressed rapidly and he died 30 months after presentation.

9/200. Intramuscular hemangioma of the masseter muscle.

    Intramuscular hemangiomas (IMH) are uncommon tumors of the head and neck, but often occur in the trunk and extremities. When present in the head, the masseter muscle is the most frequently involved site, although constituting only 0.8% of all hemangiomas. Accurate preoperative diagnosis is uncommon without cytology or biopsy. A case of IMH of the masseter muscle in a 24-year-old Turkish woman is presented. Clinical, radiologic and histologic findings and treatment modalities are reviewed.

10/200. Intramuscular spindle cell hemangioendothelioma.

    Spindle cell hemangioendothelioma occurring in skeletal muscle is extremely rare. No reported studies have performed an imaging evaluation of intramuscular spindle cell hemangioendothelioma. We report on such a tumor arising in an unusual site, the right extensor digiti minimi, in a 46-year-old woman. An en bloc resection was performed and the patient has been disease free for 8 years. Radiologic imaging in the present case showed similar findings to those described in intramuscular hemangioma.
