Distant metastases to the larynx are rare. We describe the case of a 46-year-old man who was referred to our head and neck surgery clinic with a 6-week history of sore throat and otalgia. He was found to have a laryngeal lesion that was consistent with a primary myxoid liposarcoma that had been extirpated from a lower extremity earlier To the best of our knowledge, no case of myxoid liposarcoma...
Myxoid liposarcomas (MLSs) are genetically defined by the presence of DDIT3 gene fusions and most commonly arise in the extremities of young adults. Whether MLSs develop primarily in the retroperitoneum is controversial, and a recent retrospective study found no molecularly confirmed examples. Because MLSs tend to metastasize to deep soft tissues, purported examples of primary retroperitoneal l...
Liposarcomas are neoplasms of mesodermic origin, are derived from adipose tissue and represent <1% of all malignant tumours. Primary liposarcomas of the kidney are very rare. Here, we present the cases of two patients diagnosed with retroperitoneal perirenal myxoid liposarcoma. The patients were diagnosed via imaging, which in both cases revealed a huge right retroperitoneal tumour mass compres...
Soft tissue myoepithelioma is a rare neoplasm composed of myoepithelial cells. Here, we describe the cytologic features of soft tissue myoepithelioma arising on the right forearm in an 18-year-old man. The excised tumor (3.0×1.8×1.5 cm) was well-demarcated, yellow-gray, soft, and myxoid. The cytologic smears showed round to spindle, epithelioid, and plasmacytoid cells in the myxoid background. ...
Chondromyxoid fibroma (CMF) is the least common benign cartilaginous tumor, comprising less than 0.5 to 1% of all skeletal neoplasms. This subject was a 16-year-old female with a three-year history of pain involving the distal femoral metaphysis. This case showed an unusual feature: it was intracortical in location. Radiologic differential diagnosis included metaphyseal fibrous defect, perioste...
Liposarcomas are one of the most common primary lesions of the retroperitoneal region. They rarely exhibit intra-abdominal location. Because the symptoms emerge later on, they often remain unnoticed until they grow large. Our aim in this paper is to present a case of myxoid liposarcoma of descending mesocolon origin, 40 cm wide and weighing 7000 g, seen in a 47-year-old male patient. No cases a...
