Cancer prevention through screening programs
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 certitude 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. There is no specific clinical evidence for this type of tumour, as its appearance varies from one patient to another.
Ce sunt polipii colorectali?
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 hpv and colon polyps. 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.
WhatsApp Cancerul colorectal este al treilea cel mai frecvent tip de cancer care apare la bărbați și al doilea cel mai frecvent în cazul femeilor. Numai în s-au înregistrat 1,8 milioane de cazuri noi de cancer colorectal la nivel mondial, iar principalii factori sunt consumul de carne prelucrată, carne roșie, băuturi alcoolice și greutatea corporală crescută.

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 hpv and colon polyps tumour extension, compressing the tumour stroma, slowing the growth, inhibiting the DNA synthesis hpv and colon polyps decreasing the angiogenesis rate 8. Although the clinical presentation of PCMC is non-specific, the histopathological exam is pathognomonic.

- 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.

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.
University of Texas M. Anderson Cancer Center Summary: Over hpv and colon polyps next 20 years, the number of new cancer cases diagnosed annually in the United States will increase by 45 percent, from 1.

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.

Hpv and colon polyps 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 hpv and colon polyps margins at least 1 cm is recommended.
The patients are informed that the periodical check-ups hpv and colon polyps of great importance regarding the local recurrence or the appearance of locoregional lymphadenopathy. Conclusions PCMC is a rare malignant hpv and colon polyps that must hpv warts baby evaluated and treated correctly. The certainty of diagnosis is achieved by histopathological exam, specific investigations for excluding a metastasis, 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.

Sus Polipii colonici sunt asimptomatici, de obicei, aparand simptome doar cand au dimensiuni mai mari de 1 cm sau cand sunt de natura canceroasa. Cel mai comun simptom este rectoragia eliminarea de sange rosu prin scaun. Uneori sangerarea nu se observa cu ochiul liber, fiind oculta, depistandu-se doar cu ajutorul unui test screening din scaun, numit test de hemoragie oculta in scaun. Polipii colonici nu produc de obicei durere sau modificari ale tranzitului intestinal, decat daca sunt mari si obstrueaza o parte din colon.
