A case of nerve sheath tumor followed by multicentric high-grade T-cell lymphoma in an African pygmy hedgehog (Atelerix albiventris). J Vet Med Sci 2023; 85:853-857. [PMID: 37344420 PMCID: PMC10466052 DOI: 10.1292/jvms.23-0070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/06/2023] [Indexed: 06/23/2023] Open
Abstract
A 3-year-old intact male African pygmy hedgehog was presented at the Teaching Hospital of the Faculty of Veterinary Medicine, University of Belgrade, with a growth on the left side of its abdomen. After clinical examination, the mass was surgically removed, and histopathological findings indicated a nerve sheath tumor. The hedgehog fully recovered after surgery and was euthanized eight months later due to the appearance of multicentric changes in the internal organs. Further necropsy and macroscopic, cytologic, histopathologic, and immunohistochemical findings revealed that the tumor was a multicentric high-grade T-cell lymphoma. This is an unusual case of an African pygmy hedgehog with two different neoplasms-a nerve sheath tumor followed by lymphoma.

Abstract
This paper describes the clinical and pathological features of 4 different tumors, located in the integumentary, digestive, and endocrine systems, presenting in a North African hedgehog (Atelerix algirus). A 3.5-year-old female hedgehog was presented with a cutaneous mass on the right flank. The lesion consisted of a well-differentiated dermal mast cell tumor with no recurrence and metastasis after complete surgical excision. Six months later, the hedgehog developed a mass in the left lower jaw, lethargy, anorexia, and progressive weight loss. Clinical and radiographic evaluations revealed swelling, ulceration, displacement, and destruction of subjacent bone tissue, and the animal died 1 month after the onset of clinical signs. At necropsy, 2 neoplasms in the oral cavity (squamous cell carcinoma and histiocytic sarcoma) and multiple myelolipomas in the adrenal glands were detected. Metastasis of the oral squamous cell carcinoma was observed in the lungs. Although neoplasms are frequent in this species, and more than 1 type of tumor in a single individual has been occasionally reported, this is the first description of both myelolipoma and multiple concurrent neoplasms involving various organs and different cellular origins in a hedgehog.

Abstract
OBJECTIVE To describe a modified approach to neurologic examination of African pygmy hedgehogs (Atelerix albiventris). ANIMALS 12 adult hedgehogs (7 males and 5 females). PROCEDURES Aspects of the standard neurologic examination of dogs and cats were evaluated for use with awake hedgehogs, and modified approaches to evaluating their normal behavior and mentation, select cranial nerves and refexes, and gait were then identified. Behavioral analysis and gait analysis were performed by using video recordings of hedgehogs in a novel environment. Performability and repeatability of all feasible aspects of the neurologic examination were assessed. RESULTS Most aspects of the standard neurologic examination could be successfully performed, with repeatable results. However, certain aspects, especially those evaluating the pelvic limbs, were more difficult to perform successfully or were less repeatable. All hedgehogs lacked a menace response but displayed a contraction of the frontodorsalis muscle. Facial sensation testing was unreliable. CONCLUSIONS AND CLINICAL RELEVANCE The entire standard neurologic examination could not be performed in hedgehogs. However, many aspects could be performed, and together they provided baseline data for neurologic examination of this species.

Abstract
Advances in fish medicine and husbandry have increased the average lifespans of specimens in managed aquarium populations. As a result, an increased incidence and variety of neoplasia is expected. This work characterizes diverse neoplasms arising within a managed population of Atlantic bumper fish acquired via repeated collections from the Charleston Harbor region. A total of 76 neoplasms were evaluated histologically from 41 of 45 fish that died or were killed over a 46-month period, including cutaneous hemangiomas and hemangiosarcomas, lepidocytomas and lepidosarcomas, fibromas, vertebral body or cutaneous osteomas, disseminated lymphomas, testicular leiomyomas, cutaneous or branchial fibrosarcomas, myxomas, fibroblastic lepidosarcoma, teratoid medulloepithelioma, ganglioglioma, malignant nerve sheath tumour, cardiac rhabdomyoma, cutaneous rhabdomyosarcoma, soft tissue sarcoma and renal adenoma. Perioral and cutaneous lesions of vascular and scale origin were observed most frequently. Other, often malignant, neoplasms arose within these benign lesions, resulting in extensive local tissue invasion. However, excluding disseminated lymphomas, metastasis was only detected in one case of hemangiosarcoma. These findings suggest early surgical intervention may limit tissue destruction and loss of display quality. This report details a variety of common and rare neoplasms in fish, as well as the first characterizations of neoplasia in Atlantic bumper and ganglioglioma in fish.

Abstract
An 8-mo-old male African pygmy hedgehog was anorectic and ataxic; physical examination revealed tetraparesis and a gangrenous left hindlimb. Analgesic and supportive care were administered, but the animal died 3 d after presentation. Postmortem examination revealed a histiocytic sarcoma in a mesenteric lymph node with metastasis to several organs, multifocal vacuolation in the cerebral and cerebellar white matter, and a meningioma in the left lateral ventricle. We diagnosed wobbly hedgehog syndrome (WHS) with disseminated histiocytic sarcoma and lateral ventricular meningioma. Ventricular meningioma, a rare neoplasm in veterinary and human patients, has not been reported previously in hedgehogs, to our knowledge. The neurologic signs in our case were probably caused by the WHS-related vacuolar lesions and are consistent with those of reported WHS cases. Duration of illness was shorter than is typical of WHS cases, which might be related to the disseminated histiocytic sarcoma. Clinical relevance of the lateral ventricular meningioma was not evident because the ventricular mass was localized and not invasive.

Abstract
We describe a case of primary localized histiocytic sarcoma of the lumbar vertebrae in a
four-toed hedgehog. The case showed aggressive osteolysis of lumbar vertebrae on
radiography, and a soft-tissue mass effacing this region was noted, suggesting a
neoplastic lesion. No metastatic lesions were apparent. Antemortem diagnosis was
challenging, and necropsy was performed. Histopathological and immunohistochemical
findings were consistent with localized histiocytic sarcoma. This report provides
documentation of the clinical and pathologic features of an unusual form of histiocytic
sarcoma localizing to lumbar vertebrae in a four-toed hedgehog.

Abstract
African hedgehogs are susceptible to aging changes like those of other small exotic mammals. Common conditions of the geriatric hedgehog include heart disease, chronic renal disease, and dental/periodontal disease. Hedgehogs are unique in that they have an unusually short life span and a propensity for neoplasia. These 2 factors make it especially common for exotic animal practitioners to encounter geriatric hedgehogs affected by one of the many conditions outlined in this article.

Abstract
Pet hedgehog medicine and surgery is a rapidly evolving field, with some novel conditions and re-emerging diseases being reported in the literature in recent years. Skin disease and neoplasia are commonly found in African pygmy hedgehogs worldwide. Selected new and emerging diseases occurring in these commonly reported groups are discussed in greater detail, focusing on Caparinia tripilis infestation and brain tumors. This article primarily discusses African pygmy hedgehogs, with some reference to European free-living hedgehogs.
