Intravascular papillary endothelial hyperplasia, previously known as Masson's tumor, is a relatively uncommon reactive endothelial proliferation that occurs most commonly in the vessels of the head, neck, and extremities. We report a case of intravascular papillary endothelial hyperplasia in the neck in a 40-year-old female that was misdiagnosed as papillary adenocarcinoma on fine needle aspira...

Reactive lymphoid hyperplasia (RLH) is a rare benign condition that forms a mass-like lesion characterized by proliferation of nonneoplastic lymphocytes forming follicles and germinal centers. RLH is thought to represent a reactive immunological response, and some cases may arise in association with malignancy and hepatitis. Radiologically, RLH of the liver may mimic a primary or metastatic hep...

Extra nodal marginal zone B-cell lymphoma (EMZL) of the conjunctiva typically arises in the marginal zone of mucosa-associated lymphoid tissue. The pathogenesis of conjunctival EMZL remains unknown. We describe an unusual case of EMZL arising from reactive lymphoid hyperplasia (RLH) of the conjunctiva. A 35-year-old woman had fleshy salmon-pink conjunctival tumors in both eyes, oculus uterque (...

abstract background and aims. reliable immunohistochemical assays to evaluate the definitive role of mast cells and angiogenesis in the pathogenesis of oral reactive lesions are generally not available. the purpose of the present study was to compare mast cell count (mcc) and microvessel density (mvd) between oral reactive lesions and evaluation of the correlation between mcc and mvd in these l...

Background: Fibrous hyperplasia or epulis fissuratum is a name related to reactive tissue response chronic irritation and trauma caused by dentures that are not properly attached. Persistent the oral mucosa can cause carcinoma. The treatment management of becomes very challenging for geriatric patients.
 Objective: To discuss fibrous in patients with history hypertensive disease.
 Cas...

Masson’s tumor or intravascular papillary endothelial hyperplasia is a benign lesion of the skin and subcutaneous tissue. It due to reactive proliferation cells with formations related thrombus. poses an interesting diagnostic differential as clinical signs symptoms are nonspecific. The diagnosis based on histopathology. We report case hemangioma occurring right ring finger.

AIMS To assess the diagnostic accuracy of lymph node fine needle aspiration (FNA) cytology to distinguish reactive lymphoid hyperplasia from malignant lymphoma, and to evaluate the contribution of ancillary techniques applied to cytological material. METHODS Two hundred and seventy seven consecutive lymph node FNA specimens reported to be consistent with reactive lymphoid hyperplasia (n = 213...
