The spindle cell variant of papillary thyroid carcinoma (PTC) is exceptionally rare and poses significant diagnostic challenges due to its morphological overlap with other spindle cell lesions of the thyroid. We report a novel case of spindle cell variant PTC in a 66-year-old woman presenting with a TI-RADS 4 thyroid nodule, initially classified as Bethesda III on fine-needle aspiration. Histopathological examination revealed a biphasic tumor composed predominantly of bland spindle cells arranged in solid sheets and fascicles, admixed with entrapped thyroid follicles.

Achieving UVA/B-selective, skin-inspired nociceptors with perception and blockade functions at the single-unit device level remains challenging. This is because the device necessitates distinct components for every performance metric, thereby leading to complex preparation processes and restricted performance, as well as the absence of deep UV (UVB and below)-selective semiconductors. Here, to address this, we develop a structure-simplification skin-inspired nociceptor using a reverse type-II CuAgSbI/MoS heterostructure.

Solitary rectal ulcer syndrome (SRUS) is an uncommon, benign condition that presents with a wide range of symptoms mimicking other pathological conditions, often leading to misdiagnosis and delays in treatment. A 60-year-old male patient was diagnosed with SRUS with rectal stricture with the help of colonoscopy, anorectal manometry, magnetic resonance defecography, and histopathological examination. He was managed with high-fiber diet, laxatives, biofeedback therapy, argon plasma coagulation, and stricture dilatation, which effectively alleviated the patient's condition.

Despite advances in antiretroviral therapy, KS remains a significant cause of morbidity and mortality in this population, especially when diagnosis or treatment is delayed. Ocular involvement, although rare, can lead to significant functional impairment.
