Merkel cell carcinoma (MCC) is synonymous with primary cutaneous neuroendocrine carcinoma. It tends to affects elderly whites, but there is also an increased incidence among immunosuppressed patients. The recent identification of a novel polyomavirus associated with the tumor has stimulated renewed interest in its pathogenesis. MCC tends to show classic histologic features of a neuroendocrine carcinoma and is often positive for CK20, but nonclassic cytologic findings and unusual…

Merkel Cell Carcinoma Arising in an Epidermal Cyst
TLDR
An additional case of Merkel cell carcinoma arising from an epidermal cyst located in the left arm of a 57-year-old male is presented, which was positive for cytokeratin 20 and neuroendocrine markers.
Carcinoma de células de Merkel: a propósito de un caso
TLDR
The case of an inmunosupressed patient with a Merkel cell carcinoma on face and scalp, recurrent and metastatic, with an evolution consistent to reports in the literature is described.
CD99 expression in Merkel cell carcinoma: a case series with an unusual paranuclear dot‐like staining pattern
TLDR
Paranuclear dot‐like staining in several cases of MCC is noted, including cases lacking cytokeratin 20 (CK20) expression.

TLDR
Careful correlation with clinical history and judicious use of immunostain panels is essential in approaching metastases, which are diagnostically challenging given their rarity and morphologic overlap with breast carcinoma, including special types of breast cancer.
Intracranial Spread of Merkel Cell Carcinoma to the Cerebellopontine Angle
TLDR
Surgical resection should be performed when feasible to prevent local recurrence of Merkel cell carcinoma and may be followed by early adjuvant fractionated whole-brain radiotherapy and systemic chemotherapy; however, no clinical trials have been performed to demonstrate a survival benefit.
Primary Carcinoid Tumor of the Skin
TLDR
The clinical presentation, histological appearance, and management of primary carcinoid tumor of the skin can be distinguished from a visceral metastasis only by a judicious clinicopathologic correlation.
Prognostic Factors in Merkel Cell Carcinoma: A Retrospective Single-Center Study in 90 Patients
TLDR
Iatrogenic immunomodulation resulted as the main factor associated with impaired prognosis and Lack of CK20 expression was associated with better survival.
Nonlymphoid Tumors Mimicking Lymphoma
TLDR
This chapter seeks to broadly describe such imitators with attention to specific rare entities and to variants or patterns of more common tumors that mimic hematolymphoid neoplasms, as well as ancillary techniques by which to distinguish them.

Merkel cell carcinoma vs. basal cell carcinoma: histopathologic challenges
TLDR
It is strongly support the opinion of Ball and Tanhuanco-Kho that one of the most easily recognized differences between MCC and BCC on routine sections is the absence of peripheral palisading in MCC.
A Comprehensive Review of the Treatment of Merkel Cell Carcinoma
TLDR
Data from recent development support a multimodality approach, including surgical excision of primary tumor with adequate margins and sentinel lymph node dissection followed by postoperative radiotherapy in most cases, as current choice of practice with better locoregional control and disease-free survival.
Malignant melanoma with clinical and histologic features of Merkel cell carcinoma.
Merkel cell carcinoma: more deaths but still no pathway to blame.
TLDR
Recent studies have shown that Ras/MAP kinase activity is absent and possibly detrimental to this cancer, which makes MCC distinct from other UV--induced skin cancers and highlights the question of what drives this malignancy.
Primary neuroendocrine (Merkel cell) carcinoma of the skin: morphologic diversity and implications thereof.
TLDR
A retrospective review of 29 cases of primary cutaneous neuroendocrine cell carcinoma finds that the outcome of the group as a whole is similar to that recorded in previous series of MCC, with local recurrence in 32% of cases and death caused by the neoplasm in 28%.
Merkel cell carcinoma after chronic lymphocytic leukemia: case report and literature review.
TLDR
A 72-year-old man with newly diagnosed chronic lymphocytic leukemia (CLL) who developed MCC of his right upper extremity and died of bone marrow metastases at 8 months is described.
Merkel cell (primary neuroendocrine) carcinoma of the skin with nodal metastasis showing rhabdomyosarcomatous differentiation
TLDR
C capacity for divergent differentiation appeared late in the course of the tumor, which suggests a clonal origin for both components of the neoplasm.
Primary cutaneous neuroendocrine (Merkel cell) carcinoma in association with squamous- and basal-cell carcinoma.
TLDR
This is the first report of the association of NEC, SCC, and BCC in the same skin lesion and cells of NEC and SCC showed an intermingled pattern of growth, whereas those of BCC were "embedded" among those of the other two tumors.
