The Question
“Dear Dr Paola,
Mr Crowley is a mini-panther and he has he small bumps on his trunk where there shouldn’t be, but what really concerns me is a crusty, sticky growth on the tip of his chin, about the size of a pea which can not be seen. I only felt it and it really concerns me. Thanks,“ – Steve
Quick Info about Mr Crowley
Hi Steve,
I completely understand your concern. Any unexpected changes in Mr. Crowley’s skin, especially a crusty or sticky growth, deserve attention. The chin is a common area for feline acne, which can lead to clogged follicles, small bumps, and even secondary infections. However, since you describe the growth as firm, sticky, and crusty, there are other possibilities to rule out, including an infected follicle, a cyst, or even something more complex like eosinophilic granulomas AKA “rodent ulcer” or a type of skin tumor.
The small bumps on his trunk could be related or a separate issue, such as allergic dermatitis, insect bites, or another type of skin reaction. Since skin conditions can have a wide range of causes, and most require specific treatments, the best approach would be to have him seen by a veterinarian. They may perform a skin scrape, cytology, or even a biopsy if needed. In the meantime, avoid touching the area, and if he uses plastic bowls, I recommend switching to stainless steel, as plastic can harbor bacteria and often contributes to skin irritation.
I truly hope it’s something simple and treatable for Mr. Crowley, but given the crusty texture and persistence of the growth, an in-person exam would be the best way to ensure he gets the care he needs.
Best wishes, Dr. Paola
