2965. Eyelid masses - Sebaceous (tarsal) adenomas or meibomian gland tumours

Nov 26, 2016 Sat

9-year-old, male, not neutered Shih Tzu rubs his left eye nowadays. Eye discharge, conjunctivitis and blepharitis. Corneal ulceration and keratitis are seen.

Since clinical signs are now present, surgery to remove this eyelid mass is done. Histopathology advised. Usually the eyelid mass is a benign sebaceous (tarsal) adenoma. 10-25% of eyelid masses are malignant and include squamous cell carcinoma, melanoma, adenocarcinoma, basal cell carcinoma, haemangiosarcoma and fibrosarcoma. The average age of dogs showing eyelid neoplasia is 8 years. 

Histopathology to differentiate inflammatory from neoplastic lesions and should be performed for definitive diagnosis. . 

He bites if anybody touches his left ear, the vertical canal was much swollen with a tumour. Hence, the cotton bud could not pass into the canal unlike the right ear. Advised vertical ear canal resection.

Painful enlarged prostate when palpated. Advised castration.
