Skin papilloma in humans and animals is a relatively common dermatological problem. The most common form of these changes are acquired papillomas, and while congenital ones are rare, they were most often described in humans and horses. The present article describes the first case in Poland of congenital single skin papilloma in a newborn thoroughbred foal, surgically removed using a CO₂ laser. The treatment was carried out after 3 months from birth when the change began to progress. Removal was performed on the standing animal with pharmacological sedation. Histopathological examination confirmed the diagnosis. The convalescence process proceeded without complications, with quick healing and no scar remaining.
Physical and functional abnormalities of the lids or adnexal ocular structures may result in abnormalities of the cornea and subsequently vision. Cancer begins when normal cells start to change and grow uncontrollably, forming a mass called a tumor. Eyelid tumors can be either benign or malignant. The most common malignant eyelid tumors include basal cell carcinoma, sebaceous gland carcinoma, squamous cell carcinoma and malignant melanoma. Cytologic examination of the fine needle aspiration and biopsy samples may reveal a specific type of neoplasm. All cancers from the eyelid and eye globe need to be removed. Histologic examinations of incised masses are recommended.
