We report a very rare type of tumor in the left nasal ala in an elderly patient. An 81-year-old Saudi woman known to have hypertension, osteoporosis, and rheumatoid disease (who had been compliant to her medications) presented with a 0.5-cm fixed, firm, round well-defined nodule on the left ala of the nose (with crusting, erosion, and telangiectasia of the overlying skin), whose size had been gradually increasing for 2 years. The patient underwent excisional biopsy, and the specimen was sent for a histopathologic analysis. Macroscopic examination showed a round tan-white homogenous nodule, measuring 0.6 × 0.5 × 0.5 cm. Microscopic examination revealed a fairly circumscribed unencapsulated dermal lesion, featuring basaloid cells with peripheral palisading, and focal stromal clefting. The final diagnosis of basal cell carcinoma with sebaceous differentiation was made. The patient was managed with Mohs surgery with clear margins, and full-thickness skin graft was done. Four months after surgery, the patient had a recurrence, which was managed with a surgical excision (with 4-mm margin) and covered by a full-thickness skin graft.

Objective: This study aims to explore the expression patterns of cysteine string protein alpha (CSPα) and cysteine string protein beta (CSPβ) in the mammalian inner ear, with an emphasis on their temporal dynamics during the developmental stages of C57BL/6 mice.
Methods: We utilized immunofluorescence staining to assess the localization and distribution of CSPα and CSPβ within the inner ears of C57BL/6 mice and miniature pigs. Additionally, this method facilitated the investigation of their temporal expression profiles.

Purpose: Eyelid infiltrative basal cell carcinoma (iBCC) is the most common malignant tumor affecting the ocular adnexa, but studies on metabolic changes within its microenvironment and heterogeneity at the tumor invasive area are limited. This study aims to analyze metabolic differences among iBCC cell types using single-cell and spatial metabolomics analysis and to examine metabolic environment at the tumor invasive area.
Methods: Single-cell transcriptomic data of human basal cell carcinoma (BCC) were clustered and visualized using Uniform Manifold Approximation and Projection.

The adult central nervous system (CNS) hosts several niches, in which the neural stem and precursor cells (NPCs) reside. The subventricular zone (SVZ) lines the lateral brain ventricles and the subgranular zone (SGZ) is located in the dentate gyrus of the hippocampus. SVZ and SGZ NPCs replace neurons and glia in the homeostatic as well as diseased or injured states.

A 72-year-old man with advanced locally invasive basal cell carcinoma of the forehead failed several pretreatments including surgery and radiation. MRI was not feasible because of the presence of facial implants. CT scan did not provide clear evidence of vital/avital tumor sites as a result of slow progression and previous radiation treatments.

The red-eared sliders (Emydidae: Trachemys scripta) is characterised by a high adaptability to a variety of environment and threatens the habitat of Japanese native species. The ability to digest a variety of diets may attribute to the high adaptive capacity of this species to various environments, however, the digestive morphology remains scarcely described in red-eared sliders. In this study, we investigated the macro- and microscopic anatomy of the esophagus, stomach, small intestine, and large intestine in red-eared sliders.
