A 3-year-old, 420 g, intact male African pygmy hedgehog () was presented with a sudden appearance of a mass protruding from its preputium. A detailed physical examination revealed the presence of a polyp-like mass, connected to the mucous membrane of the penis and a second, multilobular mass with a larger base. Both masses were surgically removed. While the histopathological examination of the polyp-like mass revealed only a chronic active inflammatory reaction, the histopathological examination of the multilobular mass revealed a tumorous tissue composed of spindle-shaped cells, irregularly oval or polygonal in some places. Focal tumour cells with a myxoid differentiation were observed in the greater part of this tumour. The stroma was made up of sparse fibrous tissue. The surface epithelium was hyperplastic with ulcerations and necrosis. The tumour was classified as a myxofibrosarcoma. Two weeks post-surgery, the patient did not show any clinical signs of the presented disease. According to our knowledge, this is the first published case of the surgical treatment of penile myxofibrosarcoma in an African pygmy hedgehog.

Neoplastic diseases are common in African pygmy hedgehogs (), with squamous cell carcinoma (SCC) being the most prevalent oral tumor. Traditional imaging techniques like computed tomography (CT) have limitations in accurately defining tumor extent and detecting metastasis. In this study, a hedgehog with a suspected oral tumor underwent 18F-FDG PET/CT imaging, revealing a hypermetabolic lesion consistent with SCC and indications of metastatic activity.

A wave of studies has recently emphasized the influence of sex chromosomes on both lifespan and actuarial senescence patterns across vertebrates and invertebrates. Basically, the heterogametic sex (XY males in XX/XY systems or ZW females in ZW/ZZ systems) typically displays a lower lifespan and a steeper rate of actuarial senescence than the homogametic sex. However, whether these effects extend to the senescence patterns of other phenotypic traits or physiological functions is yet to be determined.

Article Synopsis
- * The study involved examining stool samples from 49 BaAka Pygmies using various microscopic methods to identify intestinal parasites, revealing four nematode species, with hookworm being the most common.
- * Despite WHO-recommended deworming efforts reducing some infections, the persistent high prevalence indicates a need for improved sanitation and healthcare strategies to control STH spread in this community.

Article Synopsis
- Malaria is a major health issue in Africa, particularly affecting the BaAka Pygmies in the Central African Republic, where a study was conducted to assess asymptomatic cases and identify the malaria species involved.
- The research involved screening 308 individuals, revealing that 50.3% of children and 17.1% of adults tested positive for malaria using rapid diagnostic tests, while molecular tests confirmed even higher infection rates.
- Results showed high rates of asymptomatic malaria, especially in adults, suggesting increased protective immunity with age, and highlighted the presence of multiple malaria species beyond the most common one in the area.

Small mammals are very popular companion animals, and the incidence of particular tumour types in these animals is the subject of extensive research. We carried out a retrospective and comparative analysis of the incidence of reproductive tract and mammary tumours and tumour-like lesions collected from 103 pet rabbits, 75 pet rats, 71 guinea pigs, 12 mice, 11 hamsters, eight African pygmy hedgehogs, four ferrets and two chinchillas. The results indicate that uterine tumours and tumour-like lesions are common in pet rabbits, guinea pigs and African pygmy hedgehogs.
