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.

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, inhibiting the DNA synthesis and decreasing the angiogenesis rate 8.

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 pancreatic cancer genetic or environmental pH of 2.

Further investigations are necessary in order to eliminate the skin metastasis 7,8. Cancer - Wikipedia The immunohistochemistry exam can pancreatic cancer genetic or environmental 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 pancreatic cancer genetic or environmental 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. Cancerul — de la etiologie la abordări terapeutice 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.
