Helvin tikit poistettiin maanantaina ja haavat ovat parantuneet hyvin. Samalla sain kopion labratutkimuksesta ja vastaus kuuluu näin: Histopathologic examination

Submitted material: 1) one sample 20 x 16 x 7 mm in size, 2) one sample 55 x 30 x 12 mm in size (lesions on the back and lesion on left front leg)

Description: 1) Expanding the dermis and extending in the subcutis there is an unencapsulated, 7 mm in size, multicystic lesion composed of numerous, different in size cystic structures, separated by mild fibrocollagenous stroma, characterized by a wall that presents abrupt keratinization and multifocal gradual keratinization in which all the layers of the squamous epithelium can be identified: basal, spinous, granular and corneal. Within the lumen of the cysts there is abundant keratin and ghost cells. At the periphery there is mild fibrocollagenous hyperplasia. 2) Expanding the dermis and extending in the subcutis there is an unencapsulated, 19 x 12 mm in size, multicystic lesion composed of a large central cystic structure associated with small cystic structures at the periphery. The cysts are characterized by a wall that presents abrupt keratinization and multifocal gradual keratinization in which all the layers of the squamous epithelium can be identified: basal, spinous, granular and corneal. Within the lumen of the cysts there is abundant keratin and ghost cells. At the periphery there is moderate fibrocollagenous hyperplasia.

Margins: 1-2) The lesions are not present at cut borders. Diagnosis: 1-2) Trichoepithelioma. Behaviour: 1-2) Benign. Prognosis: 1-2) Fair. Comment: 1-2) The tricoepithelioma is a benign neoplasia originating from the wall of the follicle. The complete excision is curative. Your sample was examinated by: D. Caliari D.M.V Dipl. ECVP Veterinary Pathologist.

Kyseessä oli siis kaksi trikoepitelioomaa eli karvatupen kasvainta. Ne olivat hyvälaatuisia ja eläinlääkäri sai kasvaimet kokonaan pois (poistettiin varsin suurella marginaalilla etenkin selästä, jossa oli ns. varaa eli löysää nahkaa) joten tämä hoitui tällä.
