(Animals : an open access journal from MDPI (2025), PMID:41007981)\n\n> A three-year-old male bearded dragon (<i>Pogona vitticeps</i>) exhibited acute anorexia. Biochemistry revealed mild hyperproteinemia (88 g/L) and elevated liver enzymes (ALT 60 U/L, AST 272 U/L), while the hematology report showed marked lymphocytosis. The animal had been clinically normal at a routine examination 10 months earlier. Based on the clinical and laboratory findings, acute lymphoblastic leukemia was suspected. Treatment was initiated with methylprednisolone (1 mg/kg PO q24h), marbofloxacin (10 mg/kg IM q24h), and lomustine (80 mg/m<sup>2</sup> PO q14d), calculated according to reptile-specific body surface area formulas. A transient stabilization was followed by sudden deterioration on day 3, characterized by hematemesis and severe respiratory distress, leading to spontaneous death. A complete necropsy including histopathology and anti-CD3 immunohistochemistry revealed disseminated infiltration of neoplastic T-lymphocytes throughout all major visceral organs and confirmed the diagnosis of T-cell lymphoblastic lymphoma/leukemia (L/L). This case represents a rare report of systemic acute lymphoblastic L/L in a bearded dragon and underlies the importance of comprehensive diagnostics in reptiles with non-specific clinical signs and the challenges in the treatment of neoplastic diseases in exotic species.\n\n  — *verbatim, Europe PMC PMID:41007981*\n\n\n### Evolution of ZW Sex Chromosomes in &lt;i&gt;Ptyas&lt;/i&gt; Snakes (Reptilia, Colubridae): New Insights from a Molecular Cytogenetic Perspective. (International journal of molecular sciences (2025), PMID:40429685)\n\n> Snakes are cytogenetically dynamic, characterized by largely conserved diploid chromosome numbers although displaying varied variable evolutionary stages of their sex chromosomes. This study examined four snakes, with a special focus on the genus <i>Ptyas</i>, to provide evolutionary insights into the evolution of ZW sex chromosomes. We performed an extensive karyotype characterization using conventional and molecular cytogenetic approaches, described for the first time the karyotype of <i>Ptyas korros,</i> and revisited the karyotype descriptions of <i>P. mucosa</i>, <i>Chrysopelea ornata</i>, and <i>Fowlea flavipunctatus</i>. We found that all species except <i>F. flavipunctatus</i> have highly heterochromatic W chromosomes enriched in satDNAs or microsatellite repeats. Repetitive sequences accumulate with the heterochromatinization of the W chromosome but are not necessarily associated with this process, demonstrating the dynamic makeup of snake sex chromosomes. Autosomal locus-specific and sex chromosome probes from <i>Pogona vitticeps</i> and <i>Varanus acanthurus</i> did not show hybridization signals in <i>Ptyas</i> snakes, suggesting divergent evolutionary pathways. This finding highlighted the dynamic nature of sex chromosome evolution in snakes, which occurred independently in lizards.\n\n  — *verbatim, Europe PMC PMID:40429685*\n\n\n## Claims (verified C1 substrings of source_file)\n\n- `A three-year-old male bearded dragon (<i>Pogona vitticeps</i>) exhibited acute anorexia.
