PCMC is more frequently found in males and it usually hpv expression meaning 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 certitude is difficult to establish until further investigations hpv expression meaning made, in order to eliminate the primary malignant tumour with visceral location with mucine production that can hpv expression meaning at cutaneous level, as for example that of breast, gastrointestinal tract, lung, kidney, ovary, pancreas, or prostate.
Translation of "papilom" in English
The metastatic lesions that originate from the breast or colon are prone to mimic the cutaneous mucinous carcinoma 4. 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, apocrine hidrocystoma, another location primary tumour metastasis and in certain circumstances the clinical differentiation includes vascular lesions as those found in the Kaposi sarcoma 5.
What is HPV?
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 celular differentiation grade. Moreover, the presence of big mucus accumulations can serve as physical barrier in tumour extension, compressing the tumour stroma, slowing the growth, hpv expression meaning the DNA synthesis and decreasing the angiogenesis rate 8.
Although the clinical presentation of PCMC is non-specific, the histopathological exam is pathognomonic.
In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. Hpv expression meaning has been demonstrated that the human papillomavirus HPV type 16, a subtype of the human papillomavirus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive. HPV-infected cells hpv expression meaning some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and the retinoblastoma-type protein RBP involved in the regulation of proliferation and cell death.
Usually, the tumour is well delimitated, with small accumulations or tubules of epithelial cells which float in mucine. Mucine is separated by fine collagen fibres septa and is positive to PAS stain, mucicarmina, alcian blue at a pH of 2. Mucine, same as sialomucine, was characterized as sialidase-labile.

PCMC cells remain hpv expression meaning 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. These can be excluded using systemic suplimentary investigations and another types of immunohistochemistry specific colorations 9.
Because the skin metastases originating from breast and lung can express the p63 protein, the use of this expression remains controversial and so, further investigations are mandatory.

In a complex analysis of the skin metastasis, Brownstein et al. The treatment of PCMC imposes local surgical excision.
Because of the high local relapse rate, the proper excision with oncological safety margins at least 1 cm is recommended. The patients are informed that hpv expression meaning periodical check-ups are of great importance regarding the local hpv expression meaning or the appearance of locoregional lymphadenopathy.
Conclusions PCMC is a rare malignant tumour that must be evaluated and treated correctly.
