Alveolar soft-part sarcoma (ASPS) is an uncommon soft-tissue neoplasm, which is commonly found in the deep soft tissues of the extremities, with a propensity for recurrence and metastasis. However, the metastasis of ASPS to the heart is exceedingly rare. The present study reports such a rare case with cardiac metastasis. Using computed tomography, a 37-year-old man was diagnosed with brain, lun...

Anaplastic lymphoma kinase (ALK) rearranged spindle cell mesenchymal tumours are an emerging category of soft tissue neoplasm with variable clinical and pathological features.1–3 We describe a case 6-year-old female who presented pigmented lesion on her abdomen. Biopsy the showed low-grade dermally based prominent storiform architecture, some entrapped collagen focal extension into subcutis. Th...

Angiofibroma of soft tissue is a very recently characterized, histologically distinctive benign mesenchymal neoplasm of unknown cellular origin composed of 2 principal components, the spindle cell component and very prominent stromal vasculatures. It usually occurs in middle-aged adults, with a female predominance. Herein, we describe the clinical and pathologic details of 2 other examples of t...

Tumors that metastasize to the oral cavity, comprising only about 1% of all oral malignant neoplasms, rarely affect oral soft tissues. The aim of the present case series report is to retrospective study five patients with metastatic tumors to oral soft tissues, retrieved from an institution in southern Taiwan. The age, gender, sites and histological types of the primary tumor, sites of the oral...

background: this was a retrospective cephalometric study to develop a more precise estimation of soft tissue changes related to underlying tooth movment than simple relatioship betweenhard and soft tissues. materials and methods: the lateral cephalograms of 61 adult patients undergoing orthodontic treatment (31 = premolar extraction, 31 = nonextraction) were obtained, scanned and digitized befo...

Low-grade appendiceal mucinous neoplasm (LAMN) is a malignant lesion of the appendix with an unknown etiology. It rare occurrence and incidental finding only few cases documented in literature. We present case 55-year-old male 5-day history diffuse abdominal pain, which then localized to right lower quadrant (RLQ). Abdominal imaging revealed soft tissue mass around appendix, eventually leading ...

BACKGROUND Ameloblastic carcinoma secondary type is an extremely rare and aggressive odontogenic neoplasm that exhibits histological features of malignancy in primary and metastatic sites. It arises through carcinomatous de-differentiation of a pre-existing ameloblastoma or odontogenic cyst, typically following repeated treatments and recurrences of the benign precursor neoplasm. Identification...

Schwannoma is a benign nerve sheath neoplasm which mainly locates in the soft tissue but rarely originates in the bone. Intraosseous Schwannoma is prone to occur in the mandible and sacrum, while its occurrence is seldom seen in the calcaneus. Herein we report an 18-year-old man with a chief complaint of pain in the right heel. Radiographs revealed a huge, osteolytic, and expansile lesion with ...
