Abstract
Background Neoplastic lesions of the mammary gland, lymph nodes, or oral cavity in African pygmy hedgehogs (Atelerix albiventris) are common in captive animals. Chemotherapy and radiotherapy protocols have not yet been established for the African pygmy hedgehog. Thus, surgical resection is the current treatment of choice in this species. Case presentation A 5-year-old male African pygmy hedgehog showed multiple erythematous, round small tumors located in the oral cavity, on both sides of maxilla. The treatment of choice was surgical resection of tumors using a surgical knife under general anesthesia. Excised neoplastic lesions were diagnosed as peripheral odontogenic fibroma by histopathology. Six months after surgery relapse of tumors in the oral cavity was not observed. Conclusions The treatment adopted in this case report is safe for the patient and provides the best solution for mild proliferative lesions of the oral cavity. To our knowledge this is the first report of surgical resection of oral tumors (peripheral odontogenic fibroma) in the African pygmy hedgehog.

Abstract
An African pygmy hedgehog (Atelerix albiventris) was diagnosed as chylous ascites with biliary cirrhosis. Abdomenocentesis revealed a milky fluid with a 324 mg/dl triglyceride level. On serum biochemical examination, the hedgehog had hypoalbuminemia, hypoglycemia, and high blood urea nitrogen. There was no cytologic or genomic evidence of infection, and a blood culture was negative. Histopathologic examination revealed a liver with proliferative bile ducts that were often surrounded by prominent septa of fibrous connective tissue. In the area of ductular reaction, proliferative cells positive for CD66, an embryogenic antigen of epithelial cells, were revealed. The potential association between chylous ascites and liver cirrhosis is undetermined but could be an aspect of future study. This is the first description of chylous ascites in a hedgehog.

Abstract
The aim of this study was to determine diameters of blood cells, differential counts of peripheral blood leukocytes, alpha-naphthyl acetate esterase (ANAE), acid phosphatase (ACP-ase) activity of some leukocyte types, and enzymatic positivity percentages of peripheral blood lymphocytes in two hedgehogs species, Hemiechinus auritus, the long-eared hedgehog, and Erinaceus concolor, the southern white-breasted hedgehog. Air-dried peripheral blood smears were stained with May-Grünwald-Giemsa stain. ANAE and ACP-ase were stained in glutaraldehyde-acetone-fixed smears. ANAE-positive lymphocytes displayed a dot-like positivity pattern characterized with 1-5 reddish brown cytoplasmic granules, whereas ACP-ase positive lymphocytes displayed a dot-like positivity pattern characterized with 1-3 pinkish cytoplasmic granules. Monocytes gave a diffuse and strong reaction while neutrophils displayed a weak positive reaction for ANAE and ACP-ase. No difference was observed in mean diameters of peripheral blood cells of these species. It was found that lymphocytes made up the majority (64.3% and 65.5%) of leukocytes, followed by neutrophils (23.9% and 23.3%), eosinophils (9.0% and 7.6%), monocytes (1.8% and 2.3%), and basophils (1.0% and 1.3%) in H. auritus and E. concolor, respectively. Mean ANAE positivity oflymphocytes was 36.6% and 51.3% and ACP-ase positivity was 32.1% and 37.5% for H. auritus and E. concolor, respectively. The ANAE positivity of lymphocytes in E. concolor was significantly (P < 0.05) higher than that of H. auritus.

Abstract
This article discusses the respiratory anatomy, physiology, and disease of African pygmy hedgehogs (Atelerix albiventris) and sugar gliders (Petaurus breviceps), two species commonly seen in exotic animal practice. Where appropriate, information from closely related species is mentioned because cross-susceptibility is likely and because these additional species may also be encountered in practice. Other body systems and processes are discussed insofar as they relate to or affect respiratory function. Although some topics, such as special senses, hibernation, or vocalization, may seem out of place, in each case the information relates back to respiration in some important way.

Abstract
A 15-yr-old, male lesser Madagascar hedgehog tenrec (Echinops telfairi) presented with a mass caudal to the right ear. Cytology suggested a sarcoma. Surgical removal was attempted. Histology was consistent with a soft tissue sarcoma. The mass recurred within 331 days post operation. Radiation therapy was initiated. Computed tomography was used for staging in conjunction with three-dimensional computerized treatment planning software to permit accurate lesion localization and to optimize normal tissue sparing. A total dose of 6,480 cGy was administered in 24 fractions over 46 days. Transient hind limb paresis developed during the course of the radiation therapy, but resolved after 7 days with prednisone treatment. Minimal acute radiation toxicity was observed. The mass responded with at least a 90% reduction in volume following radiation treatment. The animal survived 266 days from the initiation of treatment. On necropsy, a small mass and granulation tissue were found at the site of the initial neoplasm, indicating good regional control of the tumor; however, extensive metastases to the spleen and liver were present. Immunohistochemically, the original, recurrent, and metastatic populations were strongly positive for HMB 45 and weakly positive for S-100, and the final diagnosis was metastatic amelanotic melanoma.

Abstract
A 2–year-old, female hedgehog presented with an 8–month history of progressive, ascending paresis/paralysis and was tentatively diagnosed with wobbly hedgehog syndrome. She died awaiting further diagnostic tests, and the owners consented to postmortem examination. Grossly, the bladder was large and flaccid and the cervical and lumbar spinal cord were regionally enlarged, light grey, and friable with multifocal hemorrhages. The thoracic spinal cord was grossly normal. Microscopically all regions of the spinal cord had similar changes, although the cervical and lumbar sections were most severely affected. These regions were completely effaced by a moderately cellular infiltration of highly pleomorphic polygonal to spindle shaped cells, mineralization, and necrosis, which were most consistent with anaplastic astrocytoma. The thoracic spinal cord white matter was similarly infiltrated by the neoplastic cells, with perivascular extension into the otherwise normal grey matter. A diagnosis of anaplastic astrocytoma was confirmed using immunohistochemical stains that were positive for glial fibrillary acidic protein and S100.

Abstract
Little information is available about diseases and pathology of species within the family Tenrecidae, including the greater hedgehog tenrec (Setifer setosus), a Madagascan insectivore. This report summarizes necropsy and histopathologic findings of neoplasia in four captive greater hedgehog tenrecs. Although only four animals are included in this report, neoplasia seems to be a common and significant source of morbidity and mortality in greater hedgehog tenrecs. Types of neoplasia identified include a thyroid follicular-solid carcinoma, two urinary bladder transitional cell carcinomas, uterine endometrial polyps, and multicentric B-cell lymphoma. Due to small sample size, no etiology could be determined, but genetics, viral infection, pesticide treatment, nutrition, or other environmental factors might contribute to the development of neoplasia in this species. This is the first report of neoplasia in greater hedgehog tenrecs.

Abstract
A surgically excised biopsy representing a subcutaneous mass on the left side of the neck from a 3-year-old female European hedgehog (Erinsceus europaeus) was presented. Spontaneous myxosarcoma was diagnosed based on histological, immunohistochemical, and ultrastructural characteristics. The neoplasm grossly consisted of a firm, pale, multilobulated mass with a characteristic clear gelatinous fluid. Histologically, the neoplasm was nonencapsulated and composed of pleomorphic stellate or spindle-shaped vimentin and periodic acid-Schiff-positive cells arranged in loose sheets and occasionally whorls. The neoplastic cells were suspended in Alcian blue-positive stroma and contained infrequent mitotic figures. Evidence of a viral etiology was not detected using electron microscopy and polymerase chain reaction. This is the first case report of a myxosarcoma in a captive European hedgehog.

Abstract
Mammary tumour samples (11 surgical and five post-mortem) from 16 adult European hedgehogs submitted between 1980 and 2004 were examined. Histologically, the tumours were classified as simple tubulo-papillary carcinomas with local invasive growth. In six cases, tumour cell emboli were present in blood vessels or lymphatic vessels, or both. However, metastasis to regional lymph nodes was found only in one hedgehog. Malignant neoplastic epithelial cells were immunolabelled by antibodies specific for various cytokeratins (CKs), including CK1-8, 10, 13-16, 19 and 20. CK expression did not differ from that in normal mammary gland tissue. CK20 was expressed in the mammary tissue of hedgehogs, in contrast to that of dogs and cats; CK7 immunolabelling, however, which commonly occurs in mammary epithelial cells, was negative. CK20 expression, together with the lack of CK7 as determined by a protein-specific antibody, represented an important difference from the CK profile shown by mammary epithelial cells of other mammalian species, including the dog and cat.

Abstract
A 3-year-old African hedgehog (Atelerix albiventris) was presented to the Exotic Animal Clinic of the University of Montreal for evaluation of a mass growing on the right thoracic wall. The diagnostic workup, which included helical computed tomography, confirmed the presence of a large mass, originating from the right 7th rib, infiltrating the thoracic wall and cavity. The animal was euthanized due to the poor prognosis. At necropsy, a well-demarcated mass penetrated the thoracic wall and incorporated the 6th to 8th ribs. Cut sections of the tumor were white, glistening, firm, and gritty. Microscopically, it was composed of polyhedral to elongated cells with interspersed trabeculae of osteoid and large areas of coagulative necrosis. On the basis of histopathologic findings, a diagnosis of osteoblastic osteosarcoma was made. To the authors' knowledge, this is the first report of an osteoblastic osteosarcoma on the thoracic wall of an African hedgehog, as well as the first report of the use of helical computed tomography in that species.

Abstract
The most common tumor of guinea pigs is bronchogenic papillary adenoma; of hedgehogs is mammary gland adenocarcinoma; of hamsters is adrenal cortical adenoma; of gerbils is ovarian granulosa cell and theca cell tumors; of mice is pulmonary carcinoma; and of rats is mammary fibroadenoma. A relatively low incidence of tumors is described for chinchillas and hamsters, whereas the incidence of tumors is high for gerbils, hedgehogs, mice, and rats. Limited literature regarding neoplasia exists for prairie dogs, sugar gliders, and chinchillas.

Abstract
Fifteen captive female African hedgehogs (Atelerix albiventris), 3- to 5-yr-old, were diagnosed with proliferative uterine lesions (n = 28). Lesions were associated with vaginal bleeding in all cases, hematuria in 11 of 13 cases, and weight loss in 7 of 12 cases. Lesions were multiple in eight cases and single in seven cases. The lesions identified were 13 adenosarcomas, 7 endometrial stromal sarcomas, 6 endometrial polyps, 1 adenoleiomyosarcoma, and 1 adenoleiomyoma. In one animal with adenosarcoma, peritoneal seeding was detected at the time of hysterectomy. Mean survival time was 303 days (n = 10). Ovariohysterectomy allows prolonged survival of hedgehogs with uterine tumors.

Abstract
A male African pygmy hedgehog (Atelerix albiventris), estimated to be 3 years old, presented with exophthalmos and fixed abduction of the right eye. Radiographic examination revealed a retrobulbar tumor in the right orbital cavity. The mass was surgically resected but recurred 3 months later and the hedgehog died. There was no gross or microscopic evidence of salivary or lacrimal gland involvement of the tumor at surgery or at necropsy. The histopathologic, immunohistochemical, and ultrastructural findings were those of acinic cell carcinoma, the origin of which was unknown. This is the first known case of acinic cell carcinoma in an African hedgehog.
