Eccrine carcinoma
From Felipedia
Eccrine carcinoma are malignant tumors of the sweat glands in cats, showing differentiation to eccrine secretory epithelium. Commonly they are seen on the foot pads. There is no breed redilection for this type of infiltrative nodular neoplasm.
[edit]
Histology
- Very uncommon tumor
- Differentiation of eccrine carcinoma from apocrine carcinoma is exceedingly difficult and requires knowledge of the site of origin of the tumor (footpad in dog and cat) for a definitive diagnosis
- Neoplastic cells may have a pale eosinophilic cytoplasm and small hyperchromatic nuclei, suggesting thaey are differentiating to eccrine glandular epithelium
- In the dog, the glandular, papillary or cribiform aggregates of carcinoma cells are surrounded by a sclerotic stroma
- Must be differentiated from metastatic carcinomas
