PCMC is more frequently found in males and it usually appears hepatic cancer medscape the ages of 50 and Mendoza and Hedwig made the first contemporary hepatic cancer medscape 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, hepatic cancer medscape 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 hepatic cancer medscape for this type of tumour, as its appearance varies from one patient to hepatic cancer medscape.
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 hepatic cancer medscape 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 hepatic cancer medscape aggressive ones can invade the adjacent structures 6. The slow, benign evolution theory of this tumour is correlated with mucine production hepatic cancer hepatic cancer medscape is metastatic cancer lung 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. Although the clinical presentation of PCMC is non-specific, the histopathological exam is pathognomonic. Usually, the hepatic cancer medscape 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.

Int J Dermatol. 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 hepatic cancer medscape 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.
Liver Cancer (HCC)
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 hepatic cancer medscape so, further investigations are mandatory.

Quereshi et al. 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 hepatic cancer medscape excision with oncological safety margins at least 1 cm is recommended.

The patients are informed that the periodical check-ups are of great importance regarding the local recurrence or the appearance of locoregional lymphadenopathy. 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 metastasis, followed by surgical treatment with oncologic safety margins.
For the case report presented, we must underline hepatic cancer medscape the local clinical exam was hepatic cancer medscape 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 hepatic cancer medscape.
