    Clinical characteristics and management of different neoplasias in African pygmy hedgehogs (Atelerix albiventris): Case series
    (Eesti Maaülikool, 2026) Hakkarainen, Natalia Hannele; Erm, Marina (advisor); Allmang, Cristin (advisor); Kliinilise veterinaarmeditsiini õppetool
    Neoplasia is commonly reported in African pygmy hedgehogs (Atelerix albiventris) and is often associated with a poor prognosis. There is limited clinical information available regarding their diagnosis and management. The aim of this study was to describe the clinical characteristics, diagnosis, and management of neoplasias in African pygmy hedgehogs from 14 hedgehogs presented to a private veterinary clinic in Finland between 2021 and 2025. Data were analysed retrospectively as a descriptive case series. A total of 18 tumors representing 7 different tumor types were identified. Lymphomas and sarcomas were the most common neoplasms. Most tumors were malignant, and some animals had more than one tumor. The clinical signs were often non-specific, including reduced activity, abdominal distension, and the presence of masses. In many cases, animals were presented at an advanced stage of disease. Surgical treatment was performed in some cases, but recurrence or progression was observed, and euthanasia was often performed due to poor prognosis. In conclusion, neoplasia appears to be common in African pygmy hedgehogs and is frequently associated with poor outcomes. Early recognition of non-specific clinical signs and increased awareness of neoplastic diseases may improve diagnosis and support clinical decision making in veterinary practice.

    Trichoblastomas and it subtypes in dogs from Estonia
    (Eesti Maaülikool, 2025) Vaccaro, Alessia Vaccaro; Järveots, Tõnu (advisor); Blank, Ivar (advisor); Allmang, Cristin (advisor); Chair of Veterinary Biomedicine and Food Hygiene
    This study aimed to retrospectively describe trichoblastomas and its subtypes in dogs from Estonia. The aims was to describe histological features of trichoblastoma subtypes, the occurrence of trichoblastomas in different body sites and to determine whether there is a connection between trichoblastoma occurrence and breed, age, sex or neuter status. The data consisted of 23 tumors from 22 dogs. The samples were collected between 2013 and 2023 from different clinics located in Tallinn, Tartu, Pärnu and Võru. All samples were examined at the Histology laboratory of the Estonian University of Life Sciences, Institute of Veterinary Medicine and Animal Sciences, Chair of Veterinary Biomedicine and Food Hygiene. Trichoblastoma is a benign hair follicle tumor commonly found in dogs. Trichoblastoma subtypes include the ribbon type, medusoid type, trabecular type, spindle cell type, granular type, solid type and type with outer root sheath differentiation. Histological examination is crucial for diagnosis and main treatment is surgical excision. The ribbon-type trichoblastoma was the most common subtype found in the study group and the head was the most commonly affected body area. The majority of dogs in the study group were middle-aged intact males. No statistically significant associations between subtype and sex, neuter status or age were found (p-value > 0.05). It was not possible to perform a meaningful statistical analysis of connection between trichoblastomas and different breeds due to the small sample size. Therefore, these results are most likely not generally representative, and the small scale of the study limits the ability to draw accurate conclusions.
