Ossifying fibromyxoid tumor (OFMT) is a rare mesenchymal neoplasm that arises in subcutaneous tissue, with that in the oral cavity extremely rare. We present a case of malignant OFMT in the tongue. A 26-year-old male noticed a painless mass in the tongue, which was extracted at a general hospital. Four years later, the tumor recurred and was resected at our department. Histologically, the recur...

Superficial acral fibromyxoma (SAFM) is a rare fibromyxoid mesenchymal tumor with a predilection for the distal extremities and frequent nail bed involvement. Superficial acral fibromyxoma typically arises as a solitary, slow-growing nodule on a toe or finger, with the great toe being the most commonly affected site. Histopathologically, SAFM characteristically presents as a well-circumscribed ...

BACKGROUND Gastric submucosal tumors are commonly treated by partial resection under laparoscopy. However, the surgical resection of gastric submucosal tumors sometimes causes deformation of the stomach, especially in the case of intraluminal tumors located near the pylorus or esophagogastric junction. Such deformations can result in impaired diet intake and reduced quality of life. Laparoscopi...

We report on the case of a 40-year-old patient, with no relevant medical history, who consulted for a periungual tumor on the second finger of the left hand. The lesion, which was asymptomatic, had appeared 2 years earlier, and had shown slow, progressive growth. The physical examination showed a 1-cm diameter tumor with poorly defined borders that was not attached to the deep layers (Fig. 1A)....

Inf lammatory pseudotumor of the urinary bladder is a rare entity that mimics a malignant bladder tumor both clinically and radiographically. We report a 66-year-old man, presented with gross haematuria. Intravenous urography (IVU), computed tomography (CT), and magnetic resonance imaging (MRI) al l demonstrated a pedunculated polypoid mass originated from the dome of the bladder and invaded th...

BACKGROUND Plexiform angiomyxoid myofibroblastic tumor (PAMT), also known as plexiform fibromyxoma, is a rare distinctive benign intramural tumor, typical of gastric antrum, commonly causing mucosal ulceration with upper gastrointestinal bleeding and anemia, effectively treated by complete surgical resection usually accomplished by distal gastrectomy. METHODS AND RESULTS We herein report a 47...

Myxoid DFSP expresses apolipoprotein D and presents with a storiform pattern and characteristic subcutaneous infiltration. Diagnosis is confirmed by detection of the chromosomal translocation t(17;22). The differential diagnosis should include benign myxoid lesions with spindle-shaped cells (myxoid neurofibroma, superficial angiomyxoma, mucous cyst), malignant myxoid lesions with spindle-shaped...

Editor Superficial acral fibromyxoma is a rare, distinctive soft tissue benign neoplasm that has a predilection to develop on the hands and feet of adults. Except for the only rare location on the palm, superficial acral fibromyxoma usually involves the fingers and toes, and the big toe tends to be the most frequently affected site. Most cases of superficial acral fibromyxoma tend to occur in e...

The ossifying fibromyxoid tumor (OFMT) of soft parts is a rare soft tissue neoplasm of uncertain lineage. The most common metastases are found in the lung. Herein, we present the first case report of pulmonary metastasis of ossifying fibromyxoid tumor with intracardiac extension, which was resected carefully using cardiopulmonary bypass and cardiac arrest. Subsequently pulmonary left lower lobe...

Dermatofibroma is a common benign fibrohistiocytic tumor with many clinicopathological variants. Myxoid dermatofibroma is one of these variants, which is characterized by marked stromal mucin deposition. This report presents a case of myxoid dermatofibroma on a great toe that had been slowly growing for two years. Histopathologically, the relatively well-circumscribed dermal tumor was separated...
