abstract
A one and half-year old, non-descriptive, spayed, female dog was presented with a history of gradual increase in the diameter of single, round, soft, subcutaneous nodule on the rhinarium for the past 4 weeks. Cytological examination revealed basophilic cytoplasm and round to oval nuclei with indentation, chromatin and prominent nucleoli. It was diagnosed as cutaneous histiocytoma. Complete regression of the tumour observed in two months without treatment which implies the self-cure nature of the tumour over a period of the time.
