A 46-year-old woman presented with headache and right hemiparesis. MRI demonstrated a mass in the left middle fossa. Total resection was performed. A histological examination of the tumor specimen showed several characteristic morphological features. A chordoid meningioma showing an epithelial-like palisade arrangement was observed. An anaplastic short spindle cell tumor exhibiting a fascicular pattern was considered to be a rhabdomyosarcoma. After conventional radiotherapy, the tumor was well controlled without any neurological deficit for 20 months...

Patients treated with radiation have an increased risk of developing second cancers, of which carcinomas, sarcomas, and hematological malignancies have most commonly been reported. Neuroendocrine carcinomas (NEC) are rarely reported in patients previously treated with radiation. Two patients, who had successfully undergone chemoradiotherapy for head and neck cancers at our institution, developed secondary NEC within the radiation field more than five years after the treatment. Both patients underwent curative-intent treatment of secondary malignancies, one with chemotherapy, radiation and surgery (Case 1) and the other with chemotherapy and surgery (Case 2)...

Soft-tissue sarcomas are uncommon and heterogeneous tumors of mesenchymal origin. A soft-tissue mass that is increasing in size, greater than 5 cm, or located under deep fascia are criteria for suspicion of sarcoma. Diagnosis, treatment, and management should preferably be performed by a multidisciplinary team in reference centers. MRI and lung CT scan are mandatory for local and distant assessment. A biopsy indicating histological type and grade is needed previous to the treatment. Wide surgical resection with tumor-free tissue margin is the primary treatment for localized disease...

Langerhans cell sarcoma (LCS) is a neoplastic proliferation of Langerhans cells with notably malignant cytological features. Reports of LCS are sparsely available in English literature; to the best of our knowledge, only 55 cases have been reported. The present study reports a case of LCS originating from subcutaneous tissue of the left knee in a 75-year-old man. The diagnosis of LCS was supported by the results of magnetic resonance imaging, histological and immunohistochemical studies. The tumor began to metastasize to inguinal lymph nodes and eventually involved multiple organs...

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the pediatric population. In 35% of cases, RMS develops in the head and neck (H&N) region, and only combined therapy is recognized as a curative treatment. However, recent advances in skull base and reconstructive surgery, along with microsurgery and endoscopic surgery, have strengthened the role of surgery as an important part of RMS treatment. In the present study, 36 pediatric RMS cases (24 males and 12 females) were analyzed after surgical treatment...

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) represents less than 0.1% of all tumors, but it is considered the most common skin sarcoma. Wide local excision (=5 cm) has been largely replaced by Mohs micrographic surgery; however, recurrence is not rare. Description of the case: A 35-year-old man presented with a large tumor on the upper side of his back and underwent local excision with the possible preoperative diagnosis of lipoma. Upon histological examination, the diagnosis of DFSP was made, and the patient underwent wide local excision with skin flap reconstruction and was referred for adjuvant radiotherapy...

Soft tissue sarcomas (STS) are rare tumours arising in mesenchymal tissues, and can occur almost anywhere in the body. Their rarity, and the heterogeneity of subtype and location means that developing evidence-based guidelines is complicated by the limitations of the data available. However, this makes it more important that STS are managed by teams, expert in such cases, to ensure consistent and optimal treatment, as well as recruitment to clinical trials, and the ongoing accumulation of further data and knowledge...

Synovial sarcoma is a soft tissue sarcoma especially encountered in the lower extremities. The infratemporal fossa is quite a rare location. Since it is a closed location, combined approaches and multidisciplinary planning always need to be considered. This case emphasizes the high-grade character of synovial sarcoma, which causes it to recur often. The difficulty of clear surgical margins in the infratemporal fossa adds to synovial sarcoma a second challenging issue. Therefore, the need of complementary therapy is essential...

BACKGROUND: Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas that arise at an estimated frequency of 8% to 13% in individuals with neurofibromatosis type 1 (NF1). Compared with their sporadic counterparts, NF1-associated MPNSTs (NF1-MPNSTs) develop in young adults, frequently recur (approximately 50% of cases), and carry a dismal prognosis. As such, most individuals affected with NF1-MPNSTs die within 5 years of diagnosis, despite surgical resection combined with radiotherapy and chemotherapy...

Primary sarcomas of the central nervous system are rare. These tumors is rapid growth often produces mass effect on the brain. Diagnosis is rendered pathologically after resection. Surgical resection is the mainstay treatment and need the adjuvant therapy. We report a 44-year-old female with a meningeal sarcoma of frontal meninges. She complained headache for 2 months and palpable forehead mass for 3 weeks. Brain MRI demonstrated a soft tissue mass sized as 5.3×3.7×3.1 cm with well-defined osteolysis on the midline of the frontal bone...

INTRODUCTION: Head and neck sarcomas are rare and difficult to manage surgically. Factors that influence the prognosis include the type and grade of tumour, resection margins, the anatomical site and patient-specific parameters. We review our experience as plastic surgeons working in a bone and soft-tissue tumour multidisciplinary team (MDT) in managing these tumours surgically. METHODS: Data on all patients with sarcoma of the head or neck managed surgically from 2004 to 2015 was reviewed...

OBJECTIVE Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft-tissue sarcomas. Resection is the mainstay of treatment and the most important prognostic factor. However, complete resection of spinal MPNSTs with tumor-free margins is challenging due to the likelihood of residual tumor cells. The objective of this study was to describe whether the type of Enneking resection in the management of spinal MPNSTs had an effect on local recurrence and survival. METHODS The AOSpine Knowledge Forum Tumor developed a multicenter database that includes demographic, diagnostic, therapeutic, local recurrence, and survival data on patients with primary spinal column tumors...

Corné P G Nel, Mahendra Daya
BACKGROUND: Large defects arising from extirpation surgery of buttock sarcomas requiring adjuvant radiotherapy are best closed with flap surgery. The traditional solutions are derived from an approach to pressure sores, which were designed for the ischial, sacral, or trochanteric areas, and have now been adapted for true buttock defects. This invariably destroys the esthetics of the buttock. We describe a novel technique of sigmoidplasty, which preserves most of the esthetic features...

INTRODUCTION: Breast metastasis is rare in childhood malignancies. Soft tissue sarcomas, especially rhabdomyosarcomas (RMS), and hematologic neoplasms, such as lymphomas, are the most common tumors that metastasize to the breast, albeit rare. MATERIALS AND METHODS: All cases with breast metastasis within a cohort of 200 RMS patients followed in our institution during 1990 to 2014 were assessed retrospectively and the literature was reviewed. RESULTS: There were 3 adolescent female patients with breast metastasis...
