Skin metastases of a bronchial adenocarcinoma in a cat (case report)
 |
Skin metastases of adenocarcinomas are sometimes seen in dogs, most often deriving from a primary mammary adenocarcinoma. This description of a metastatic bronchial adenocarcinoma in a cat is very interesting and seems to be unique. Or do some of our miliary dermatitis cats have skin tumours?

This case report describes a cat with metastasis of a bronchial adenocarcinoma to the abdominal skin.
The cat had been treated with antibiotics and corticosteroids for several episodes of coughing when it acutely developed erythema, pustules and plaques on the abdominal skin.
Diagnosis was based on cytological examination of fine-needle aspirates of cutaneous pustules, X-ray examination of the thorax and histological examination of skin biopsy samples.
As the prognosis was poor, the cat was euthanased.
Necropsy findings confirmed the diagnosis. Cutaneous metastases of lung carcinoma are rare in cats but have been reported in the digits with underlying bone involvement. To the authors` knowledge, this is the first report of metastasis of a feline bronchial carcinoma to the ventral skin.
