We report an unusual case of a malignant blue nevus in a five-year-old girl, which turned out to be malignant only after the development of lymph node metastases three years after the excision of the primary tumor on the patient's cheek. A functional bilateral neck dissection was performed and the patient is alive with no evidence of disease 8 years after the excision of the primary skin lesion.

background : interleukin (il)-4 is a member of t helper 2 (th2) axis produced by t-lymphocyte and mast cell. it has been shown that il-4 expression changes in tumor tissues. the main objective of this study is to investigate the expression of il-4 mrna in patients with laryngeal squamous cell carcinoma (lscc) with or without lymph node involvement. materials and methods: mrna expression of il-4...

Castleman's disease, or angiofollicular lymph node hyperplasia, is a relatively rare disorder characterized by the benign proliferation of lymphoid tissue related to the chronic human herpes virus 8 (HHV-8) infection and the human immunodeficiency virus (HIV). Two clinical entities have been described: a unicentric presentation with the disease confined to a single anatomic lymph node and a mul...

background: the role of diagnostic pathology has become more prominent. this study aimed to compare the accuracy of frozen section compared with permanent section in the morning and afternoon working hours. methods: in this cross-sectional study, 99 patients with stage 1 and 2 breast cancer who underwent sentinel and non-sentinel lymph node biopsy between 2013 and 2015 were included. the result...

background and objective: fine needle aspiration cytology (fnac) is a well-established method of diagnosis in palpable masses of various sites. this study was conducted to evaluate the usefulness of fnac as a diagnostic tool in the management of patients with cervical lymphadenopathy. patients and methods: totally 178 patients admitted to loghman-hakim hospital , tehran, iran, with cervical mas...

the charts of 27 patients with kawasaki disease (kd) admitted to nemazee hospital in shiraz from january 1991 to october 1998 were reviewed to identify the results of mean peroxidase index (mpxi) values, a measure of neutrophil staining intensity, obtained by the technicon hi analyzer (technicon instruments corp., tarrytown, ny) within the first 10 days of the illness 2 separate groups of patie...

Castleman's disease is an uncommon benign disorder associated with progressive lymph node enlargement. It most commonly involves the mediastinum and involvement of the neck accounts for 6%. A 28-year-old male presented with a progressively enlarging left-sided neck mass. He had a history of excisional lymph node biopsy that yielded a histopathologic diagnosis of reactive lymphadenopathy. In our...

A 44-year-old man was referred to our hospital because of persistent high fever. Both CT and PET-CT demonstrated lymph node lesions limited to the mediastinal region without cervical lymphadenopathy. Histology of a mediastinal lymph node obtained by video-assisted thoroscopic excision confirmed the diagnosis of histiocytic necrotizing lymphadenitis. To our knowledge, this is the first report of...

Castleman's disease is one of the rare entities which cause lymph node hyperplasia with no characteristic clinical symptoms. Pathomorphological examination usually enables diagnosis, especially in the case of a localized form. Its uncommon location in the retroperitoneal cavity is estimated at 12% in the literature. Asymptomatic nature of the disease and its untypical location in the adrenal fi...

There are occasional reports of unexpected pathological findings during neck dissection, including benign inclusions (BIs) in cervical lymph nodes, comprising squamous epithelial, glandular, thyroid, neval and mesothelial cells. BIs can mimic regional lymph node metastases, therefore, pathological diagnosis is important. However, criteria for immunohistochemical diagnosis of BIs are not establi...
