A unique case of merkel cell carcinoma with ovarian metastasis

A rare tonsillar metastasis of Merkel cell carcinoma: A case report

Merkel cell carcinoma (MCC) metastasis to the tonsil is extremely rare with five published cases. We report the case of a patient with palatine tonsillar MCC metastasis, who presented without oropharyngeal symptoms, which contrast prior reported cases.

A Report of 13 Cases of Merkel Cell Carcinoma: Single-Center Experience and Review of the Literature

Background

There is limited data knowledge of Merkel cell carcinoma (MCC) in Turkey aside from a few case reports.

Objective

The aim of this study was to describe the clinical characteristics, demographic features, therapeutic parameters, and outcome of primary cutaneous MCC cases from Turkey.

Methods

Digital medical records of the 13 MCC patients who were followed-up at a tertiary referral center were retrospectively analyzed. Clinic, demographic, tumor characteristics, and survival of the patients were retrieved.

Results

Most of our patients were elderly. Female predominance was noticed. The most common primary site of the tumors was the lower extremities. The overall survival was 42 months, 68% at first year, 68% at third years, and 29% at fifth years.

Conclusion

This is the first largest report from Turkish population with female predominance, and lower extremity tendency.

A rare case of Merkel cell carcinoma with ovarian metastasis

Introduction

Merkel cell carcinoma (MCC) is a rare cutaneous malignancy that normally occurs in sun-exposed areas of the skin. Risk factors are immundeficency and Merkel cell polyomavirus.

Treatment options are surgery, radiotherapy, chemotherapy and immunotherapy in clinical trials.

Case report

We describe a case of an 80-year-old woman with ovarian metastasis of MCC six years after excision of a cutaneous MCC on the cheek.

Discussion

To our knowledge only three cases with ovarian metastasis of MCC have been described so far. Our case is the second with distant metastasis to the ovary spreading from a primary tumor in the skin of the head, in the other two cases the primary tumor was in the inguinal skin.

Conculsion

MCC is a highly aggressive cutaneous and mucosal malignancy with frequent recurrence, lymph node and distant metastases. There is no clear consensus how to treat metastatic disease.

•

MCC is a rare malignancy.

•

Recurrence and metastases are frequent.

•

There is little knowledge of treatments for metastatic MCC.

[Cutaneous Merkel cell carcinoma: role of 18FDG PET-CT]

Merkel cell carcinoma (MCC) is a rare neuroendocrine carcinoma of the skin with unpredictable evolution and high metastatic potential. This neoplasm usually occurs in the elderly on their sun-exposed areas. CCM constant greed for 18 fluorodeoxyglucose (FDG) defines the role of positron emission tomography (PET) in this pathology. However, no consensus has yet been reached. This study reports the case of a 25 year old woman treated for metastatic MCC, in order to draw attention to this particular tumor and to illustrate the role of 18 FDG PET in the management of this rare entity.
