Traumatic ulcerative granuloma with stromal eosinophilia is a reactive, self-limiting ulcer within the oral cavity; however, clinically, it mimics a malignant ulcer. Here, we report the case of a 13-year-old boy who presented with a painful solitary indurated ulcer at the lower lip for a week. Histopathological examination revealed an ulcerated lesion with significant infiltration of eosinophils, small lymphocytes, and large lymphoid cells. Further immunohistochemistry showed the inflammatory cells were CD3-positive T cells and CD68-positive, with a minority of the cell population showing CD30 positivity. CD1a-positive dendritic cells were also observed. We discuss the clinical and histopathological differential diagnoses of Langerhans cell histiocytosis and CD30-positive T-cell lymphoproliferative disorders and how to correlate them in formulating the final diagnosis.

The diabetic foot consumes a large number of resources and has a profound negative impact on quality of life, representing the major non-traumatic cause of lower limb amputation in adults. The present report describes a diabetic patient with a recurrent plantar ulcer in the topography of the heads of the second, third, and fourth metatarsals. The patient was treated using the distal metatarsal diaphyseal osteotomy (DMDO) technique in these bones, an Akin-type percutaneous osteotomy in the proximal phalanx of the hallux, and debridement.

Purpose: Corneal pain is one of the most common eye symptoms caused by various types of epithelial injuries, including traumatic abrasion, chemical injury, ulcers, ultraviolet exposure, and infection. However, current therapeutic options for corneal pain are limited. In this study, we synthesized a novel quaternary ammonium compound, N-propylamiodarone bromide (NPA), and employed a rodent model of corneal injury to investigate whether NPA offers prolonged corneal analgesia through transient receptor potential vanilloid 1 (TRPV1) channel-mediated selective cellular entry, without hindering corneal epithelial recovery.

Objective: To investigate whether hydrogen sulfide (HS) protects against intestinal ischemia/reperfusion (I/R) injury in rats by regulating c-Jun N-terminal kinase/activator protein-1 (JNK/AP-1) signaling pathway.
Methods: Thirty male Wistar rats were divided into sham operated group (Sham group), I/R group, and HS donor sodium hydrosulfide (NaHS) intervention group (I/R+NaHS group), with 10 rats in each group. The I/R injury model was established by blocking the superior mesenteric artery with a non-traumatic vascular clip, with 60 minutes of ischemia followed by 120 minutes of reperfusion.

Chromoblastomycosis is an uncommon, chronic granulomatous fungal infection of the skin and subcutaneous tissue. Chromoblastomycosis is most commonly caused by the traumatic inoculation of dematiaceous (pigmented) fungi, most commonly species, species, and species. Chromoblastomycosis usually affects agricultural workers in tropical and subtropical climates.
