The accurate histopathological evaluation, the diagnosis, and the assessment of level of invasion of malignant melanoma have assumed a role of paramount importance in defining need for further surgery, a chemotherapeutic or immunotherapeutic approach to management, and prognosis. The classification of melanoma into lentigo maligna melanoma, superficial spreading melanoma, and nodular melanoma a...

chronic liver disease, celiac disease, mastocytosis, and AIDS, and as an increased immune response in intravenous drug users [3]. Lymphadenopathy occurs as benign hyperplasia and proliferation in response to infection and/or antigenic stimulation. The features of lymph nodes on ultrasound or CT scan, such as size, number, or distribution, are important in the evaluation of abdominal lymphadenop...

This paper reviews scanning electron microscopic observations of cellular elements forming various lymphoid organs. The reticular cells in the secondary lymphoid organs are stellate, smooth-surfaced forms extending slender processes to comprise a three-dimensional network. The reticular fibers are usually covered by reticular cell processes, though they are naked in certain regions. Other types...

Cutaneous malignant melanoma is an aggressive tumor characterized by early lymph node metastasis and bad prognosis. Although the spread of tumor cells in the regional lymph nodes is very important in the staging, prognosis and therapeutic strategy of malignant melanoma, the mechanism(s) of initial lymphatic vessels invasion is are) not completely understood. In the present review, we analyze th...

CUTANEOUS MALIGNANT MELANOMA OF THE BREAST CAN BE DIVIDED INTO TWO CATEGORIES: primary and metastatic lesions. Cutaneous malignant melanoma of the breast is a rare tumor, accounting for less than 5% of all malignant melanomas. Clinical features and diagnostic methods of primary cutaneous malignant melanoma of the breast are similar to those arising from other cutaneous areas. Treatment of choic...

The aim of this paper was to present the ultrasound (US) and computed tomography (CT) appearance of a patient with salivary duct carcinoma of the parotid gland. US showed a voluminous mass of the parotid gland, with multiple calcifications. Furthermore, it revealed regional multiple lymph nodes with malignant characters. Sonoelastography of the lesion and lymph nodes detected increased rigidity...

D uodenocolic fistula (DCF) is a very rare entity characterized by fistulous communication between duodenum and transverse colon; DCF owing to metastatic lymph nodes is even rarer. Intractable explosive diarrhea is the most consistent and troublesome symptom in DCF. Treatment is mostly palliative. We present the case of a patient with malignant DCF owing to lymph node metastasis from carcinoma ...

  Background :Cell proliferation is one of the most critical factors in metastasis and prognosis of the malignant tumors.Recent investigations show that the eosinophil granolosytes have an important role in developing of malignant tumors. The relation between cell proliferation and eosinophilic infiltration in oral squamous cell carcinoma (OSCS) with prognosis is unclear.The aim of this study w...

Silicone implants are widely used in aesthetic and reconstructive breast surgery. Silicone lymphadenopathy is a well-known rare complication of implant insertion. Silicone leakage from a rupture or silicone bleeding can accumulate in lymph nodes. Foreign body reactions in the affected lymph nodes may be misdiagnosed as metastasis or malignant lymphadeno pathy upon initial presentation if silico...
