The oncologic risk of ionizing radiation is widely known. Sarcomas developing after radiotherapy have been reported, and they are a growing problem because rapid advancements in cancer management and screening have increased the number of long-term survivors. Although many patients have undergone radiation treatment in Asian countries, scarce reports on post-radiation sarcomas (PRSs) have been published. Read More

Microphthalmia-associated transcription factor (MiTF) is used as a marker of melanocytic differentiation. However, MiTF immunoexpression has also been observed in histiocytes, macrophages, smooth muscle cells and fibroblasts, which raise the concern of fibrohistiocytic (FH) lesions being misdiagnosed as melanoma based on MiTF immunoreactivity. MiTF has been known to be positive in FH tumors, but this is the first study evaluating ninety-three fibrohistiocytic neoplasms to understand and delineate the staining pattern of MiTF in these tumors.

Plantar fibromatosis, also known as Ledderhose's disease, is a benign fibroblastic disorder of plantar aponeurosis, more specifically the medial side of the foot arch. Magnetic resonance imaging (MRI) has an important role in the diagnosis, staging, and determining the deep extension found in advanced, aggressive forms of plantar fibromatosis, thereby guiding appropriate clinical and surgical management. This case report aims to provide radiologists and clinicians with simple guidelines for the differential diagnosis of the fibroblastic and fibrohistiocytic soft tissue tumors of the foot with the emphasis on the MRI findings.

Successful raising of a distally based anterolateral thigh (dALT) flap mainly depends on a well-developed lateral circumflex femoral artery (LCFA) descending branch and an intact vascular connection between the descending branch and the vascular network of the knee. However, in some clinical scenarios, the descending branch is hypoplastic or the vascular connection of the knee is compromised. We present six cases of using dALT flaps in soft tissue defect reconstruction of the knee with either of the above-mentioned conditions. Read More

Recurrence of a soft tissue sarcoma typically manifests as a round or oval mass at imaging, and recurrent high-grade soft tissue sarcomas generally enlarge relatively rapidly. We present a case of high-grade undifferentiated pleomorphic sarcoma in the calf of a 48-year-old male that recurred as a thin, curvilinear "tail" of enhancing tissue at magnetic resonance imaging (MRI), with extremely indolent growth over a 7-year period. The unusual imaging finding of a slowly enlarging "tail" should not be dismissed as postoperative changes, even for a high-grade soft tissue sarcoma. Read More

Background: Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue neoplasm, and its rarity makes studying it difficult. We found that several of our patients with AFH presented with radiologically suspicious local lymph nodes that were sampled because of their imaging characteristics, but the nodes proved to be benign on pathologic evaluation. Although the frequency of this finding is unknown, it seems important for orthopaedic oncologists who care for patients with AFH to know whether suspicious-appearing associated nodes in these patients warrant aggressive management.
