Introduction. Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin cancer. Aim. Herein described is a case of hypertensive patient, after removal of Merkel cancer of the left gluteus skin (2011), after pulmonary embolism (2013), with degenerative changes of the spine and uterine myoma, chronically treated with Warfarin, because of suspected thyroid cancer. Description of the case. A 70-year-old woman case after removing Merkel cancer of the left buttock skin (2011), after pulmonary embolism (2013), with degenerative changes of the spine and uterine fibroids treated chronically with Warfarin because of suspected thyroid cancer is described. Conclusion. Increasing evidence of Merkel cell carcinoma with immunodeficiency and neoplasia, and the management and outcome of these patients requires study.

Cells Of Origin

Merkel cell carcinoma (MCC), a highly aggressive skin tumour with increasing incidence, is associated with the newly discovered Merkel cell polyomavirus (MCPyV). Studies on MCC and MCPyV as well as other risk factors have significantly increased our knowledge of MCC pathogenesis, but the cells of origin, which could be important targets in future therapies, are still unknown. Merkel cells (MCs), the neuroendocrine cells of the skin, were believed to be at the origin of MCC due to their phenotypic similarities. However, for several reasons, for example, heterogeneous differentiation of MCCs and postmitotic character of MCs, it is not very likely that MCC develops from differentiated MCs. Skin stem cells, probably from the epidermal lineage, are more likely to be cells of origin in MCC. Future studies will have to address these questions more directly in order to identify the physiological cells which are transformed to MCC cells.

Merkel cell carcinoma is a  rare cutaneous carcinoma from the tactile Merkel cells. With fewer than half the patients surviving more than one year and fewer than 20% surviving beyond five years. These tumors are rarely suspected until the biopsy results return. Polyoma virus is associated with up to 80% of the tumors. 53% present on the head and neck and 35% present on the extremities while larger lesions are exceedingly rare in either location. Recently, A newly approved drug, Avelumab, has shown tumor response in patients with some patients experiencing complete remission.

Viruses are the cause of approximately 15% of all human cancers. Both RNA and DNA human tumor viruses have been identified, with Merkel cell polyomavirus being the most recent one to be linked to cancer. This virus is associated with about 80% of Merkel cell carcinomas, a rare, but aggressive cutaneous malignancy. Despite its name, the cells of origin of this tumor may not be Merkel cells. This review provides an update on the structure and life cycle, cell tropism and epidemiology of the virus and its oncogenic properties. Putative strategies to prevent viral infection or treat virus-positive Merkel cell carcinoma patients are discussed.

Rare Site

Merkel cell carcinoma (MCC) is an aggressive and rare neuroendocrine cutaneous carcinoma with poor prognosis and with increasing morbidity and mortality in cases of distant metastasis. Given the rarity of MCC, optimal treatment is not well established. Treatment usually consists of multidisciplinary management with local excision of the primary tumour. Imaging studies are essential for accurate staging and monitoring of disease progression. The incidence of local recurrence is highest in the first 2 years and ranges from 27% to 60%. Distant metastasis is most common in the skin, liver, bone, lung/pleura, brain or distant lymph nodes. The thyroid gland is a rare site of metastasis for MCC with only two case reports published to date. Our patient had a repeat 2-[18F]-fluoro-2-deoxy-d-glucose-postiron emission tomography/CT after the discovery of recurrence of MCC. The high-intensity maximal standardised uptake value of 10.9 in the thyroid isthmus is consistent with malignancy. This case report describes an exceedingly rare thyroid metastasis secondary to MCC.
