Meet Rocky!

Rocky is a 2 year old neutered male white German Shepherd with a mandibular mass who presented to a veterinary specialty center for a surgical consultation.  A CT was performed to determine the extent of the mass and to prepare for surgical removal. On CT, an expansive mass was noted in the left mandible with evident destruction of the bone and cystic spaces containing numerous small structures of the same density as bone.

Upon histologic evaluation by Dr. Delaney, the mass was characterized as an odontoma, specifically a compound odontoma.  These masses originate from dental epithelium and induce the production of dentin and enamel.  The mass expanded and effaced the mandibular bone and was composed of numerous coalescing bony structures resembling teeth, referred to as "denticles" as well as palisading odontogenic epithelium along eosinophilic and more basophilic material (dentin and enamel, respectively).  Some of these teeth-like structures also had central stroma containing stellate and spindloid cells, which correlate to dental pulp.

Complex odontomas are most commonly reported in young dogs, though other types of odontogenic tumors are seen across species including horses, cats, rodent, and primates.  Most odontogenic neoplasms are benign and have no metastatic potential though can be locally destructive.  Rocky's mass was completely excised and he is expected to make a full recovery!

Meet Ashley!

Ashley, a 12 year old female spayed Domestic short hair (DSH) cat was referred to a veterinary dermatologist for a severe, persistent (almost 1 year), and progressive skin lesion on her face and nose. Ashley was pruritic (itchy) and had to wear an E-collar at all times to prevent her from further self-trauma.

Dr. Ward evaluated the biopsy from Ashley's nose and found lesions and intranuclear viral inclusions characteristic of herpes virus infection.  [BELOW: The keratinocytes (cells that make up the epidermis of the skin) are enlarged and contain glassy, smudged faintly basophilic inclusions within the nuclei.  There is substantial eosinophilic inflammation within the dermis and necrosis of the epidermis and follicular epithelium.]

Following a diagnosis of feline herpesviral ulcerative dermatitis, Ashley received the appropriate anti-viral therapy and has improved dramatically!  To date, Ashley's face and nose lesions continue to improve and her hair has begun to grow back.  No more itchiness and E-collar!
