PCMC is more frequently found in males and it usually appears between the ages of 50 and Mendoza and Hedwig made the first contemporary description of this eyelid-located tumour. Taking into consideration the rarity of this tumour, a diagnosis of human papillomavirus and liver cancer is difficult to establish until further investigations are made, in order to eliminate the primary malignant tumour with visceral location with mucine production that can metastasize at cutaneous level, as for example that of breast, gastrointestinal tract, lung, kidney, ovary, pancreas, or prostate.

The metastatic lesions that originate from the breast or colon are prone to mimic the cutaneous mucinous carcinoma 4.

The benefits are certain in some cases: life years gained for those with curable disease, avoidance of morbidity, reassurance that the disease is at a very early stage, avoiding expenses of treatment for advanced cancers and extra years of productivity. But screening tests also have disadvantages, so a balanced decision must be made, with the help of clinical human papillomavirus blood test trials. In this article I will present the current methods for screening accepted for general population and particular screening reserved for persons at high risk. Although in the first case the benefit is proven, the use of these methods in practice varies largely due to lack of resources and well designed health programs. Beneficiile sunt evidente în anumite cazuri: prelungirea su­pravieţuieii la cei cu boală curabilă, scăderea morbidităţii, asigurarea pacientului că boala se află în stadiu incipient, evitarea costurilor crescute asociate cu tratamentul for­melor avansate de boală şi creşterea numărului de ani de productivitate.

There is no specific clinical evidence for this type of tumour, as its appearance varies from one patient to another. The first clinical impression is that of a cyst, basal cell carcinoma, keratoacantoma, nevus, human papillomavirus blood test hidrocystoma, another location primary tumour metastasis and in certain circumstances the clinical differentiation includes vascular lesions as those found in the Kaposi sarcoma 5.

The patients describe a slow evolution, stretched over several years, of the lesion, completely asymptomatic. Occasional, the very old tumours or the very aggressive ones can invade the adjacent structures 6. The slow, benign evolution theory of this tumour is correlated with mucine production which is linked to its high human papillomavirus blood test differentiation human papillomavirus blood test. Moreover, the presence of big mucus accumulations can serve as physical barrier in tumour extension, compressing the tumour stroma, slowing the growth, inhibiting the DNA synthesis and decreasing the angiogenesis rate 8.

Although the clinical presentation of PCMC is non-specific, the histopathological exam is pathognomonic. Usually, the tumour is well delimitated, with small accumulations or tubules of epithelial cells which float in mucine.

Further investigations are necessary in order to eliminate the skin metastasis 7,8. The immunohistochemistry exam can facilitate the differential diagnoisis.

PCMC cells remain positive for CK 7 and negative for CK 20, the same occurs for the mucinous adenocarcinoma of the breast, but in the case of the mucinous colorectal adenocarcinoma CK 7 is negative and CK 20 is positive. This way, the absence of CK 20 excludes skin metastases originated from the mucinous colorectal adenocarcinoma. Another CK 7 positive and CK 20 negative tumours, as the adenocarcinoma of the lung or of the gallbladder, can also produce skin metastases.

Conclusions PCMC is a rare malignant tumour that must be evaluated and treated correctly. The certainty of diagnosis is achieved by histopathological exam, specific investigations for excluding a human papillomavirus blood test, followed by surgical treatment with oncologic safety margins. For the case report presented, we must underline that the local clinical exam was unspecific; the location of the tumour was extremely rare, with local invasion in sternal distal region, the anterior abdominal wall, peritoneum and mediastinum, since the diagnosis needed suplimentary investigations in order to establish the primary cutaneous mucinous adenocarcinoma.
