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.

Histopathological Features of Myxoid Pleomorphic Liposarcoma in an African Pygmy Hedgehog (Atelerix Albiventris). Vet Sci 2022; 9:vetsci9110642. [DOI: 10.3390/vetsci9110642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Revised: 10/28/2022] [Accepted: 11/17/2022] [Indexed: 11/22/2022] Open
Abstract
Myxoid pleomorphic liposarcoma is characterized by pathological features of both pleomorphic liposarcoma and myxoid liposarcoma, as the name suggests. In this case, a myxoid pleomorphic liposarcoma was observed in a 5-year-old male African pygmy hedgehog. It consisted of ~60% of the myxoid substance area with proliferating round cells and ~30% of pleomorphic neoplastic cells. The subject presented with extrapulmonary metastasis, but a good prognosis during 6 months of follow-up, which is similar to the characteristics of myxoid liposarcoma. The histopathological features of myxoid pleomorphic liposarcoma may reflect the features of either myxoid liposarcoma or pleomorphic liposarcoma depending on the proportion of each histopathological feature. The proportion of the pleomorphic area and the myxoid area may offer information on the prognosis and metastasis of myxoid pleomorphic liposarcoma, which will be helpful for setting up a treatment plan. Thus, analyzing the proportion of pleomorphic area and myxoid area could be suggested as one of the ways to predict clinical outcomes. In addition to the fact that this is the first case of a myxoid pleomorphic liposarcoma in hedgehogs, this case is meaningful, considering the unique histopathological characteristics and rare incidence of myxoid pleomorphic liposarcoma that could be important in humans as well.

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
A two-year-old male African pygmy hedgehog (Atelerix albiventris) presented with lethargy and anorexia. Ultrasonographic and radiographic examinations revealed splenomegaly and pneumonia, respectively. Prominent leucocytosis, consisting mainly of large atypical eosinophils, was observed in a peripheral blood smear. Necropsy revealed a black scab on the left hindlimb, which was swollen, an enlarged left inguinal lymph node, firm oedematous lungs, splenomegaly and multiple nodules in the lung, spleen and liver. Histopathologically, infiltration of numerous eosinophils was seen in lung, spleen, liver, kidney, lymph node and adrenal medulla tissues. Necrotizing granulomatous lesions, with intralesional acid-fast bacilli, were found in the lung, spleen, liver, left inguinal lymph node and left hindlimb. Mycobacterium marinum was identified by broad-range polymerase chain reaction targeting of the bacterial 16S rRNA gene. To the best of our knowledge, this is only the second reported case of systemic M. marinum infection in any mammalian species.

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
Histiocytic sarcoma (HS) is a haematopoietic tumour of histiocyte origin that has been sporadically reported in four-toed hedgehogs (Atelerix albiventris). The present study aimed to investigate clinical, gross, histopathological and immunohistochemical features of HS in eight hedgehogs. Histological and immunohistochemical features of normal histiocytes and Langerhans cells (LCs) of hedgehogs were also investigated. HLA-DR-, Iba-1- and E-cadherin-positive LCs were observed in the epidermis, while Iba-1- and CD204-positive histiocytes were detected in the lymph nodes and spleen of normal hedgehogs. Localized HS (six cases) developed in the skin and spleen, while disseminated HS (two cases) occurred in the intestine. Tumour cells of disseminated HS were also distributed within the mesenteric lymph nodes, liver, kidney, spleen, lung and adrenal glands. Tumour cells of both localized and disseminated HS were composed of histiocytic cells, spindle to pleomorphic cells, multinucleated giant cells and erythrophagocytic cells. Most tumour cells were immunopositive for Iba-1, CD204 and lysozyme. A small number of tumour cells were positive for E-cadherin and CD208, and the tumour cells in one case were positive for HLA-DR. These results suggest that the tumour cells have variable features of histiocyte origin, including dendritic cells, LCs and macrophages. The behaviour of HS in the hedgehog was very aggressive, and 50% of cases died within 90 days of resection. The present study also highlighted the tendency for local tumour recurrence in localized cutaneous HS cases, suggesting a requirement for a long-term follow-up after excision.

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.

Abstract
Four-toed hedgehogs presented bloody stool and loss of appetite. Integumental masses were observed in two of the four cases. Intraabdominal masses were observed on radiographs and ultrasonography in the remaining two cases. The masses were surgically removed from all four cases. All samples were histologically and immunohistochemically consistent with histiocytic sarcoma (HS). At the time of surgery, 3 of 4 cases had grossly recognized metastatic/disseminated lesions. Survival time was 48 days, 64 days, and 113 days, respectively, and the remaining case is currently alive (at Day 207). The present report describes the clinical management and outcome of hedgehogs that were diagnosed with HS.

Abstract
The African pygmy hedgehog (Atelerix albiventris) is becoming a popular
pet in Japan. The aim of this study was to determine the incidence of various diseases in
African pygmy hedgehogs. We histologically investigated 105 samples from 100
privately-owned pet African pygmy hedgehogs that were submitted to two laboratories (North
Lab and Patho Labo) between 2012 and 2017. Tissues submitted for this study were taken
from female reproductive organs (33 cases; 31.43%), skin (20 cases; 19.05%), and the oral
mucosa (19 cases; 18.1%). The most common histological diagnoses included endometrial
stromal nodules identified as benign uterine neoplasia (14 cases; 13.33%); endometrial
polyps identified as non-neoplastic polyps (7 cases; 6.67%), gingival hyperplasia and
chronic suppurative inflammation in the oral mucosa (11 cases; 10.48%), fibrosarcomas in
the skin (8 cases; 7.62%), and mammary tumors (8 cases; 7.62%). In this study, lymphoma
and oral squamous cell carcinoma were less common than in the previous reports. The
present study revealed the disease prevalence in captive African pygmy hedghogs that were
histopathologically examined.
