Squamous cell carcinoma in cat − differential diagnosis and multimodal therapeutic approach
eyelid papilloma squamous PCMC is more frequently found in eyelid papilloma squamous 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.

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 eyelid papilloma squamous 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.

The eyelid papilloma squamous 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 eyelid papilloma squamous 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 eyelid papilloma squamous 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.

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.
Case Report
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. Eyelid papilloma squamous certainty of diagnosis is achieved by histopathological exam, specific eyelid papilloma squamous for excluding a metastasis, followed by surgical treatment with oncologic safety margins.
