Plexiform leiomyoma of the esophagus: a complex radiographic, pathologic and endoscopic diagnosis

Dermal and Subcutaneous Plexiform Soft Tissue Neoplasms

This article presents an overview of soft tissue tumors that have a plexiform histomorphology. The more commonly encountered entities, including plexiform fibrohistiocytic tumor, cellular neurothekeoma, dermal nerve sheath myxoma, plexiform schwannoma, and plexiform neurofibroma, are discussed in detail, and other tumors are noted. Information on clinical features, microscopic findings, ancillary studies, differential diagnosis, and prognosis is provided for each entity.

Plexiform angiomyxoid myofibroblastic tumour of the duodenum: a rare entity

Plexiform angiomyxoid myofibroblastic tumour (PAMT) has recently emerged as a new entity among gastrointestinal mesenchymal tumours. All of the 27 cases reported until now originated from the stomach. We report the first case of a duodenal PAMT arising from the first part of the duodenum in a 19-year-old woman presenting with upper abdominal pain and an abdominal lump.

Clinicopathologic features of inflammatory fibroid polyp of the esophagus

AIM: To explore the clinical and pathological features of inflammatory fibroid polyp (IFP) of the esophagus and to discuss its diagnosis, differential diagnosis, treatment and prognosis.

METHODS: A case of IFP of the esophagus was investigated by light microscopy and immunohistochemistry. A literature review was then performed to summarize the clinical and pathological features of the disease.

RESULTS: A 71-year-old man presented with epigastric/retrosternal pain and dysphagia for 3 months. Endoscopy revealed a hemispheric lesion, 2.5 cm in size, in the esophageal mucosa about 35 cm from incisors. On EUS, the lesion (13.2 mm x 11 mm) was hypoechogenic and inhomogeneous, and was located under the mucosa of the esophagus, with a clear boundary. Surgical resection of the esophageal mass was performed, and the final pathologic diagnosis was IFP of the esophagus.

CONCLUSION: IFP of the esophagus is an extremely rare mesenchymal tumor with benign behavior and good prognosis. A correct preoperative diagnosis is difficult and relies on postoperative pathological examination. Surgical excision is the preferred treatment for IFP.
