INTRODUCTION Plasmacytoma is an uncommon plasma cell neoplasm and its localized form is solitary plasmacytoma of the bone and solitary extramedullary plasmacytoma. Solitary plasmacytoma of the mesentery is extremely rare, reported only in a handful of cases. CASE PRESENTATION A 47-year-old man with nonspecific abdominal complains was found to have an ill-defined mass on his mesenteric root. L...

Fibrous tumours arising entirely within the substance of the lung are rare. We report one such rare case in whom the diagnosis was established after surgical removal.

A 48-year-old man with a solitary fibrous tumor of the pelvic underwent resection, but recurrent tumor was found 4 years later. Recurrent solitary fibrous tumor of the pelvic with malignant progression is rare. Solitary fibrous tumor of the pelvic often has an indolent clinical course, so postoperative surveillance may necessitate long-term follow-up because of the potential adverse biological ...

Title:Determinants of outcome of solitary fibrous tumors of the pleura: an observational cohort study

Solitary fibrous tumors (SFTs) may occur at any site in the body. SFTs can only be conclusively diagnosed based on histopathologic and immunohistochemical characteristics of the tumor. The presence of SFTs in the abdomen and pelvis is extremely rare. To our knowledge no cases of urethral solitary fibrous tumor in the literature have been reported so far. We present a case of a solitary fibrous ...

INTRODUCTION Myofibromatosis is a rare tumor. Two forms are described, solitary and multicentric, the solitary type is more common and is localized mainly on the head and the neck, mandible involvement is rare. The recent observation of a patient with a myofibrome of the mandible has given the opportunity to conduct an analysis and review of the literature of this disease rarely encountered. ...

Solitary fibrous tumors are very rare neoplasms that seldomly appear in extra-serosal soft tissues. In such cases, an accurate preoperative diagnosis is often difficult and challenging, especially in extrapleural ones. Traditionally, extrapleural solitary fibrous tumours have been regarded as indolent neoplasms similar to their intra-thoracic counterparts, although there has been some evidence ...

Background and Objective: Neurofibromas occur as solitary and multiple forms. The solitary ones are extraneural and more common, histologically exhibiting spindle cells with wavy nuclei, scattered among collagen fibers. Multiple neurofibromas are seen in neurofibromatosis (types I and II), including intraneural (plexiform, cutaneous deep circumscribed) and extraneural (cutaneous, deep diffuse) ...
