A paratesticular fibrous pseudotumor is a relatively rare benign disease. Preoperatively diagnosing a fibrous pseudotumor is challenging because distinguishing these masses from malignant tumors on the basis of clinical and radiological findings can be difficult. We present a case of a 28-year-old man who presented with a painless palpable mass in the right scrotum; the fibrous pseudotumor of t...

Solitary fibrous tumors (SFTs) represent an uncommon entity most frequently manifested in the pleura. We describe herein two new cases located in the jejunal and sigmoid mesentery incidentally found in patients aged 61 and 32 years. In a review of the literature, we have compiled 15 mesenteric SFTs including our two cases. The mean age of the patients at presentation was 51.7 years (range, 26-8...

INTRODUCTION Calcifying fibrous pseudotumor is a rare benign soft-tissue lesion composed of fibrous tissue with abundant hyalinized collagen and dystrophic and often psammomatous calcifications. The cause of the disease is unclear but, usually, complete resection of the well-circumscribed tumor is sufficient to avoid recurrence of the disease. Here, we report an unusual case of this rare tumor ...

has been described in both genders of all ages, and in almost any location (1, 2). It is characterized histologically by the presence of acute and chronic inflammatory cells with a variable fibrous response (2). Its pathogenesis is uncertain, but the lesion is generally regarded as reactive or postinfectious, and it originates from an inflammatory process (2). It has been reported to occur in m...

Calcifying fibrous pseudotumor has recently been described in the soft tissues. It is a rare benign lesion characterized by the presence of abundant hyalinized collagen with psammomatous or dystrophic calcifications and lymphoplasmacytic infiltrate. We report a case of a young woman with a mediastinal mass treated by a complete resection. The mass had all the pathologic features of calcifying f...

Fibrous pseudotumor is a rare entity involving the paratestis comprising about 6%. These lesions are considered to represent a benign reactive process that chiefly affect young adults and mimic testicular tumors. We report a case of a 35 year old male who presented with a painless testicular mass since 2 year. This case is reported due to its extreme rarity and highlights the need to incorporat...

This report presents a case of calcifying fibrous pseudotumor arising in the posterior mediastinum of a 54-year-old woman. The histopathologic features of this case were identical to that of calcifying fibrous pseudotumor first designated in 1993. It is a distinctive benign fibrous lesion characterized by the presence of characteristics psammomatous or dystrophic calcification, abundant hyalini...

Reactive nodular fibrous pseudotumor (RNFP) is a tumor-like lesion that is characterized by reactive fibroblast/myofibroblast proliferation within collagenic hyalinized stroma, due to its association with injury or inflammation. The current study describes the case of a 60-year-old female with a history of abdominal surgery and abdominal pain. Upon laparoscopy, multiple nodules attached to the ...

INTRODUCTION Paratesticular fibrous pseudotumors represent benign new growths confined to intrascrotal structures. Both pathogenesis and clinical management are little understood due to the rarity of the lesion, with less than 200 cases reported to date. Recently, paratesticular fibrous pseudotumors have been postulated to be immunoglobulin G4-related, pathogenetically. Here we report two cases...
