“…It was noteworthy that vSAA concentrations moderately increased during the chronic course of trichoblastomas. As reported in the author’s previous investigations [ 15 , 16 ], vSAA agents proved useful in diagnosis of inflammatory disease in insectivorous species (Southern tamandua and Suncus murinus ). Triggering events of neoplasia alter acute phase protein revels in animal species.…”

Background Benign hair follicle tumors are relatively rare cutaneous neoplasms arising from hair follicle differentiation. These tumors are slow-growing solitary papules or nodules in the head, face or neck. The aim of this study was to describe 2 cases of trichoblastomas in tactile hair skin incidentally encountered in aged house musk shrews (Suncus murinus). In addition, this case report clarifies whether the characteristics in the tactile hair skin of Suncus murinus are different from those in humans and other animals. Case presentation The animals were investigated the characteristics of the clinical findings, hematological and serum biochemical profiles (particularly, serum amyloid A levels (vSAA)), and histopathological results. Suncus murinus with the facial tumor showed weight loss and coarse fur. Hematological examinations indicated microcytic and normochromic anemia. Although few apparent changes were serum biochemically found in Suncus murinus, vSAA levels moderately increased and revealed inflammatory reactions. These lesions histopathologically showed the basaloid islands comprising peripheral palisading and dilated microcysts containing variable admixtures of free-floating cells such as neoplasm cells, giant cells, clear cells, mononuclear cells and erythrocytes. Conclusions The author concluded that trichoblastomas in Suncus murinus revealed growth and morphological characteristics that recapitulate part of embryological development in the tactile hair follicles. In the histological structure, their trichoblastomas in the tactile hair skin were different from those found in humans and animals such as cats, dogs and other wildlife.

Background: Mönckeberg Medial Calcific Sclerosis (MMCS) is a rare condition that can mimic giant cell arteritis (GCA). It may be misinterpreted as giant cell arteritis by the clinician and cause unnecessary treatments. Therefore, it is a disease that should be differentiated from giant cell arteritis with its clinical, radiological, and pathological findings. Case Presentation: A 56-year-old female patient was admitted to our clinic with sudden unilateral vision loss on the right, pain in the right temporal artery trace, scalp sensitivity in the section corresponding to that area, difficulty chewing, and temporal artery sensitivity. He had a history of hemodialysis for 13 years due to hypertension, osteoporosis, a history of renal stones, and end-stage renal failure. In routine blood tests, White Blood Cell: 7.86X109/L, Hemoglobulin: 10.9 g/dL, C-reactive protein: 3.03 mg/L, Erythrocyte sedimentation rate: 53 mm/hour came. As a result of temporal artery biopsy performed for GCA, absence of giant cells, absence of epithelioid histiocytes, absence of pathological findings in the internal elastic lamina, diffuse calcification in the tunica media, and sclerosis was diagnosed as MMCS. Conclusions: In the literature, 4 case reports resemble giant cell arteritis and are diagnosed as MMCS. This case report is a rare case report showing that MMCS can completely mimic GCA findings.

Neutering dogs is a widespread method and is carried out for various behavioural and husbandry reasons. This study’s main objective is to investigate the behavioural correlations between neutering and the breed of male dogs. In order to possibly find breed-dependent differences in the behaviour of intact and castrated dogs, a differentiation between two clades - the “Huskies“(chow chow, shar pei, akita/shiba inu, alaskan malamute, siberian/alaskan husky) and the “Bulldogs” (german boxer, english/french bulldog, old english mastiff, boston terrier, english bull terrier, staffordshire bull terrier, american staffordshire terrier), based on Parker et al. [1], was made.Using an online questionnaire,, 31 neutered and 37 intact male dogs from the clade “Huskies“ and 30 neutered and 38 intact male dogs from the clade “Bulldogs”, participated in the study (N = 136).The survey included detailed questions on the dogs’ personality and any associated issues as well as a behavioural anamnesis. Further questions relating to four of the “big five” personality dimensions based on the “Budapest questionnaire” by Turcsán et al. from 2011 [2] were also added.The results show, that neutered males from both breed clades more frequently displayed aggression toward humans than intact males (multinomial logistic regression, p = 0.002). When it came to aggression towards other dogs, it was the “Huskies” that differed significantly from the “Bulldogs“(multinomial logistic regression, p = 0.04) with being more aggressive. There were also significant differences in stress-related behaviour depending on castration status and breed (multinomial logistic regression, p < 0.001; Cramer’s V = 0.33) and only the castration status had an impact on the significance (multinomial logistic regression, p < 0.001). The analysis also revealed significance for stress-indicating behaviour with dependence on neutering status (multinomial logistic regression, p < 0.001) and showed that stress as well as uncertainty are significantly more common in neutered dogs depending on breed and neutering status (multinomial logistic regression, p < 0.001; Cramer’s V = 0.42), in that only neutered “Bulldogs“ were stressed, but more “Huskies“ overall.According to the Budapest questionnaire data, the “Bulldog” clade had considerably greater extraversion scores overall (ordinal regression, p < 0.001) than the “Huskies“.Our findings highlight the risks and potential negative effects of neutering. Gonadectomy in no way substitutes for the dog receiving the necessary socialization, training, or bonding. Although in some circumstances it might have a favourable impact on the dog’s behaviour, it should not be seen as a panacea for unwanted behaviour. Given that not all behaviours are influenced by sex hormones, every castration decision must be weighed up individually.
