“…Gland islets formed by sebaceous and basal cells located in the dermis. Gland islets and squamous metaplasia (black arrow), comedone structure opening onto epidermal surface (K), lymphoplasmocytic infiltration (red arrow) pan (Kondo et al 2008). Thus, the fact that in this case the hamster was two years old is in accordance with the results of this earlier study (Kondo et al 2008).…”

“…The most common eyelid tumours reported in dogs are meibomian adenomas (Vascellari et al 2005;Kafarnik et al 2010), whereas in cats the most frequently described tumours are squamous cell carcinomas (Willis and Wilkie 2001). The rate of spontaneous tumour formation in hamsters has been reported to be higher in Siberian hamsters compared to Syrian hamsters (Kondo et al 2008). However, we could find no information on the incidence of eyelid tumours or on the types of tumours in hamsters.…”

ABSTRACT:A two-year old male Syrian hamster (Mesocricetus auratus) was brought to the Surgery Clinic at the Istanbul University, Veterinary Faculty, Research and Practice Hospital, with a non-healing wound on the right upper eyelid. An ulcerated, bleeding wound was observed and diagnosed as an eyelid mass. The eyelid mass was excised and submitted for histopathological examination, which resulted in a diagnosis of meibomian adenoma. After excision of the mass, the right upper eyelid became deformed and adopted an abnormal shape. The surgical site was examined two weeks later. No abnormality was observed and the appearance of the right eyelid had returned to normal. Although there are many reports on benign tumours such as polyps, adenomas, haemangiomas and papillomas in hamsters, to the authors' knowledge, this is the first report on a meibomian adenoma in a Syrian hamster which was resolved by surgery.

“…The incidence of tumours in these two species is quite different. In the analysis of tumours from 85 domestic hamsters 70 were Djungarian hamsters and 15 Syrian hamsters (Kondo et al 2008a). In the integumentary system of Syrian hamsters melanomas and cutaneous lymphoma are the most frequently detected tumours, but both are low in incidence (Percy and Barthold 1993;Brown and Donnelly 2012).…”

Tumours of the mammary gland were diagnosed in one female Djungarian hamster (Phodopus sungaros) and in two of her daughters from two litters. Altogether, five tumours were diagnosed. Three of them were adenocarcinomas, one was adenoma with disseminated foci of adenocarcinoma and one was diagnosed as an atypical fibrosarcoma derived from cutaneous ganglion cell-like cells. This was a recurrent tumour in the proximity of the previously extirpated adenocarcinoma. Using specific PCR primers for conserved regions of the mouse mammary tumour virus (MMTV) no endogenous provirus DNA could be detected in DNA samples isolated from formalin-fixed paraffin embedded tissue sections.Keywords: hamsters; neoplasias; atypical fibrosarcoma; mammary gland; clinic; pathology; molecular biology Hamsters are popular pet animals with Syrian hamsters (Mesocricetus auratus) and Djungarian hamsters (Phodopus sungaros) being among the most frequently kept species. Reports on spontaneous tumours in domestic hamsters are scarce, and most are individual case reports (Kondo et al. 2008a). The incidence of tumours in these two species is quite different. In the analysis of tumours from 85 domestic hamsters 70 were Djungarian hamsters and 15 Syrian hamsters (Kondo et al. 2008a). In the integumentary system of Syrian hamsters melanomas and cutaneous lymphoma are the most frequently detected tumours, but both are low in incidence (Percy and Barthold 1993;Brown and Donnelly 2012). Tumours of the mammary gland in Syrian hamsters are rare and only a few cases have been described in the literature (e.g. Jelinek 1986a). However, in Djungarian hamsters the incidence of cutaneous neoplasias is five times greater than in Syrian hamsters and these are predominantly represented by mammary tumours, atypical fibromas and papilomas (Brown and Donnelly 2012). Kondo el al. (2009) analysed mammary tumours from 12 domestic Djungarian hamsters. Eleven were female and one was male. Histopathology revealed three subtypes: simple adenoma, tubulopapillary carcinoma, and complex carcinoma. No angioinvasion was observed. It is the aim of this contribution to describe mammary neoplasias in a female of Djungarian hamster and her two daughters. Case descriptionClinical and gross pathology. The owners of the pets in question originally intended to acquire two female Djungarian hamsters as pets. However, in the pet shop they purchased, by mistake, one male and one female. Two months later the female gave birth to four young. After weaning, three young animals (two females and one male) and the father were sold back to the pet shop and the family retained the mother and her daughter. The mother was, however, fertilized before the weaning of offspring and one month after the first parturition, bore a second litter of young comprised of two hamsters; one died shortly after birth while the other, female, survived.A tumour of the first left mammary gland was observed in the mother at the age of 15 months. At the time of extirpation its size was 2 × 1 × 1 cm
