Abstract
Case summaryA 4-year-old male castrated domestic shorthair cat presented with a 2 cm painful cutaneous mass on its right lateral abdominal wall. The cat inflicted self-trauma to the lesion site causing secondary ulceration and mild haemorrhage. Fine-needle aspiration or incisional biopsy was advised, along with diagnostic imaging; however, excisional biopsy was preferred by the owners. The mass was surgically removed with 1 cm lateral margins and a deep fascial plane. The histopathological features were most consistent with a diagnosis of a glomus tumour; the diagnosis was supported by subsequent immunohistochemistry. The tumour was completely removed and there were no signs of recurrence at the 6-month follow-up. In this case, surgery is expected to be curative. Relevance and novel information To the authors' knowledge, this is the first report of a glomus tumour of the body wall in a cat and its association with pain and self-trauma. This report aims to add more data to the diagnosis and presentation of glomus tumours in animals.
