چکیده

Merkel cell carcinoma (MCC) is an aggressive, cutaneous, neuroendocrine carcinoma and, in rare cases, occurs with Bowen's disease (BD). In this report, we describe a case of MCC concurrent with invasive BD and compare the profiles of tumor-infiltrating leukocytes in the lesional skin of MCC and invasive BD. Interestingly, immunohistochemical study revealed significant numbers of CD8+ cells and caspase 3-expressing cells in the same areas of invasive BD and MCC. Our present case suggests that MCC concurrent with invasive BD might have a good prognosis because of the substantial number of CD8+ cells in the tumor.

Merkel Cell Carcinoma Concurrent with Bowen's Disease

Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous malignancy of the elderly and immunocompromised patients. It is occasionally found coexisting with other diseases, such as squamous cell carcinoma, basal cell carcinoma, actinic keratosis, miscellaneous adnexal tumors, and rarely Bowen disease. A 75-year-old woman presented with a 6-month history of an irregularly shaped erythematous p...

Investigation of NK Cell Population in Peripheral Blood and Tumor Lesions of Patients with Breast Cancer

Background: Alteration in peripheral blood lymphocytes (PBLs) is usually investigated to provide an evidence of the host immune responses to tumor antigens. The tumor infiltrating NK cells interact most closely with the tumor cells and more accurately reflect tumor host interactions. Objective: To analyze peripheral blood and tumor associated Natural Killer (NK) cells in patients with breast ca...

Merkel Cell Carcinoma with Spontaneous Regression: A Case Report and Immunohistochemical Study

Merkel cell carcinoma (MCC) is an aggressive neuroendocrine carcinoma that only rarely regresses spontaneously. Since little is known about the immunological mechanisms involved in the spontaneous regression of MCC, we describe a case of MCC with spontaneous regression and employed immunohistochemical staining for cytotoxic and immunosuppressive molecules to investigate possible mechanisms invo...

Flowcytometric Analysis of Tumor Associated Macrophages in Invasive Ductal Carcinoma of Breast

Background: Invasive ductal carcinoma is the most common type of breast cancer in Iran. Impaired immune responses occur frequently in cancer patients, but the mechanisms of the induced immune defects remain poorly understood. It is believed that infiltrated immune cells, especially macrophages, may provide help for tumor cell growth and metastasis.   Objective: To analyze the status of tumor as...

E-Cadherin in Relation with the Proliferating Cell Nuclear Antigen of the Bilharzia Associ-ated and Non-Associated Urinary Bladder Carcinoma

Background: E-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. Loss of the adhesive function of E-cadherin seems to promote invasive and metastatic properties of neoplastic cells. Objectives: The present study is a retrospective study aiming to evaluate the loss of E-cadher...
