Histiocitoma: O Tumor Canino Benigno Com Aparência Não Muito Amigável

Meus dois buldogues franceses sofreram de tumores inestéticos, que frequentemente coçam e tecnicamente benignos, que chamamos de histiocitomas. Embora os histiocitomas normalmente se resolvam após dois a três meses, a incerteza da proveniência desse tumor leva a maioria dos veterinários a eliminá-lo (ou pelo menos parte dele) para garantir sua benignidade.

Um escalpelamento cirúrgico de uma massa “benigna” pode parecer extremo para você, mas como os histiocitomas podem ser irritantes e assustadores, a cirurgia geralmente é indicada.

Irritante: porque costumam aparecer na cabeça e nos pés, locais onde uma massa ulcerada e perfeitamente redonda pode ser arranhada ou lambida facilmente.

Assustador: porque é difícil dizer se o que acabou de surgir na pele do seu cachorro (e geralmente acontece rápido) é um tumor de mastócito desagradável (ou alguma outra massa monstruosa) … ou seu primo mais tranquilo, o histiocitoma.

while young dogs (under three years of age) are more likely to get these, they can happen to dogs of any age. indeed, my older frenchie, sophie sue got one about a year ago. she was nine-not exactly a spring chicken. vincent has had three. and he’s not yet two years old.

some breeds are more predisposed. labrador retrievers and boxers, for example. though frenchies aren’t on the list, perhaps they should be… (perhaps they should be on the list for almost everything if my recent round of healthcare scares is any guide.)

ugly and prominently placed as they typically are, most owners want histiocytomas removed. some vets, however, will counsel owners to either wait a few weeks (especially if the dog is young and statistically less likely to be suffering from a malignant mass) or to have a simple section of it snipped (with a local anesthetic) for histopathological analysis at the pathology lab.

other vets will even take a needle poke at it, though most pathologists find that histiocytomas are not easily disgnosed definitively through this method (cytology).

if the dog is older or the mass is especially annoying to the dog or owner, however, we remove the whole sucker and clean up the mess quickly. unfortunately, though, this approach is more costly and usually requires general anesthesia. it’s nonetheless the approach i take for more than half of these tumors…better to be safe than sorry, right?

still, most owners need to know they have a choice. the nervous nellies among you (like me) are less likely to want to stare at a mass for a couple of months to see if it simply goes away. the rational or more anesthetically cautious, however, are justified in waiting-as long as their dog is young and/or hasn’t suffered from malignant masses in the past.

whatever choice you make, consider histiocytomas an excellent foray into the world of skin tumors. it’s like a warm-up for what’s likely to come as your dog ages. and it’s not all bad. look on the bright side: curing cancer is sometimes just a scalpel slice away.
