Merkel cell carcinoma is a rare aggressive primary cutaneous neuroendocrine skin cancer arising from the basal epidermis. Although the majority of patients with non-melanoma skin cancer are cured by local treatment, patients with Merkel cell carcinoma have a poor outcome characterized by locoregional and distant relapse. No standard treatment protocol for Merkel cell carcinoma exists. But, ther...

The medical literature has many case reports of the spontaneous remission Merkel cell carcinoma after biopsy [1-10]. It is noteworthy that prior to Cell Carcinoma was growing rapidly. suggested possibly resulted in breakage a vessel and blood loss within malignant tissue.

Merkel cell carcinoma represents a highly aggressive cutaneous malignancy characterized by regional recurrences, lymph node metastases, distant metastases, and high mortality. As the cytomorphology of Merkel cell carcinoma can be mimicked by other malignancies, especially lymphoma and pulmonary small cell carcinoma, immunocytochemistry is often useful in confirming the diagnosis. Cell blocks, w...

Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneo...

I read the article "Complete spontaneous regression of Merkel cell carcinoma metastatic to the liver: Did lifestyle modifications and dietary supplements play a role?"(1) with great interest. Merkel cell carcinoma carries a significant rate of recurrence and mortality.(2) Though spontaneous regression of Merkel cell carcinoma has been well documented in the literature,(3) the potential that the...

Merkel cell carcinoma is a rare, but highly malignant tumor of the skin with high rates of metastasis and poor survival. Its incidence rate rises and is currently about 0.6/100000/year. Clinical differential diagnoses include basal cell carcinoma, cyst, amelanotic melanoma, lymphoma and atypical fibroxanthoma. In this review article clinical, histopathological and immunhistochemical features of...

INTRODUCTION Merkel cell carcinoma and dermatofibrosarcoma protuberans are two very rare neoplasms. The simultaneous occurrence of two different tumour entities at the same anatomical site, collision tumours, is a rare phenomenon. CASE PRESENTATION We present a rare case of a 74-year-old woman with a previous history of a recurrent dermatofibrosarcoma protuberans presenting with a metastatic ...

BACKGROUND Merkel cell carcinoma is a rare and aggressive neuroendocrine skin cancer with a very low incidence in the general population. MCC seems to be common in transplant recipients and 52 cases have been reported in the literature. METHODS AND RESULTS This report describes a Merkel cell carcinoma which developed in a liver transplant recipient. To our knowledge, this is the second such c...

BACKGROUND Merkel cell carcinoma is a rare malignancy of the skin. Integration of Merkel cell polyomavirus (MCPyV) DNA to the tumor genome is frequent in these cancers. The clinical consequences of MCPyV infection are unknown. METHODS We analyzed formalin-fixed paraffin-embedded Merkel cell carcinoma tissue samples from 114 of 207 patients diagnosed with Merkel cell carcinoma in Finland from ...
