Abstract

Here we describe the histological lesion of a viral fibro-papilloma in a hedgehog. After surgical removal from maxilla, the solitary swollen mass was round to oval, yellowish with rough surface and measuring $6{\times}3{\times}2mm$ approximately. The tumor mass was submitted to the laboratory of pathology, college of veterinary medicine, Kyungpook National University for pathological diagnosis. Pathological examination of the tumor was established, the tumor was described grossly and sample was trimmed, sectioned and routinely prepared for histopathological evaluation. The tumor mass was diagnosed as viral fibro-papilloma, as the histological picture showed characteristic features of warts caused by papillomaviruses. The tumor characterized by thickening of the stratum spinosum (acanthosis) and basale, koilocytosis, intra-nuclear inclusion bodies in keratinocytes and fibrosis of submucosa. Further, viral inclusion bodies were demonstrated by Machiavello stain giving red color to the nuclei. No lymphocytes that responsible for regression of the wart could be detected, suggesting the poor possibility of spontaneous regression of the tumor. Papillomatosis is a disease of young animals, but in our case the infected Hedgehog was 5 years old, that maybe due to an impaired immune system, which is also shown by absence of lymphocytes. To the best knowledge of the author, this case presents the first report of viral fibropapillomatosis in Hedgehog.

고슴도치에서 발생한 바이러스성 섬유 유두종의 조직학적 소견과 관련하여 증례보고를 하고자 한다. 상악에서 발생한 단발성의 종대된 종괴는 원형 혹은 타원형의 외양을 보였으며, 표면은 거칠었며, 잇몸과 동일한 색을 나타내었고, 직경은 $6{\times}3{\times}2mm$였다. 외과적으로 절제 후, 종괴는 병리조직학적 진단을 위해 경북대학교 수의과대학 병리학교실에 의뢰되었다. 종괴는 처리과정을 거친 후 조직절편 과정 후에 조직병리학적 진단을 위해 염색 과정을 거쳤다. 조직병리학적 진단으로 본 종괴는 Fibro-papilloma로 진단되었다. 조직병리학적으로 종괴는 유두종 바이러스에 의한 사마귀와 비슷한 조직학적 소견을 보였으며, 가시층 및 기저층의 비후, 각질세포에서의 핵내봉입체, 점막하층의 섬유화가 특징적으로 관찰되었다. 또한 Macchiavello염색을 통하여 붉은 색의 핵내봉입체를 동정하였으며, 유두종의 자발적인 퇴축과 관련이 있는 림프구의 침윤은 관찰되지 않아, 본 증례의 종양의 자발적인 퇴축의 가능성이 낮음을 시사하였다. 유두종증은 주로 어린 연령의 동물에서 다발하는 것으로 알려졌으나, 본 증례의 경우 5년령의 고슴도치에서 발생한 경우로, 감소한 면역력과 관련 있는 것으로 사료된다. 본 증례는 고슴도치에서 발생한 유두종 바이러스에 의한 섬유성 유두종 증례로서, 본 저자가 알고 있는 한 최초 보고인 것으로 사료된다.
