title: Squamous cell carcinoma of the midventral abdominal pad in three gerbils.
abstract: Squamous cell carcinoma of the midventral abdominal pad was diagnosed in 3 male gerbils. Two of the gerbils had raised, ulcerated masses on the midventral portion of the abdomen. The first gerbil was 2 years old, and an excisional biopsy was performed. The gerbil survived 23 months after surgery without evidence of metastasis or clinical signs of local recurrence. At necropsy, neoplastic squamous cells were seen on histologic examination of the surgery site. The second gerbil was 4 years old, and surgical excision of the tumor with concurrent castration was curative. The third gerbil was moribund on admission, perhaps because ulceration of the tumor may have allowed bacteria to invade the tissue, resulting in septicemia and disseminated intravascular coagulation. These gerbils illustrated that hematologic, radiographic, and biochemical testing in rodents can be useful and that excision of squamous cell carcinoma tumors of the midventral abdominal pad of gerbils can be an effective treatment.
