An unusual granulomatous inflammatory lesion characterised by the presence of ring shaped hyaline bodies accompanied by foreign body giant cell reaction has been mentioned in the literature. A lack of agreement exists on the nature of these hyaline rings. Opinions ranging from their being hyaline degenerative blood vessels to remains of leguminous cells have been postulated. Although the nature and origin of these bodies is uncertain, there is now considerable evidence that they represent, at least in part, vegetable material, especially pulses, that have been implanted in the tissues. An inflammatory oral lesion in a 17-years-old male patient caused due to traumatic implantation of the vegetable matter (sugar cane) has been reported in this paper. Based on the histological finding of a granulation tissue surrounding a hyaline ring the lesion was diagnosed as hyaline ring granuloma.

Pulse granulomas are unusual foreign body reactions to exogenous plant material, featuring the presence of hyaline ring structures and granulomatous inflammation. Pulse granulomas have been reported to occur in the oral cavity, gastrointestinal tract, and respiratory tract. Cutaneous pulse granulomas are exceedingly rare.

Article Synopsis
- Oral hyaline ring granuloma is a rare lesion in the jaw, marked by eosinophilic rings and multinucleated giant cells.
- This condition can occur centrally or peripherally, often due to foreign particles in the mouth.
- The paper discusses a unique case related to an impacted premolar tooth and details its surgical treatment for the first time.

Article Synopsis
- The study investigates fibrocartilaginous dysplasia (FCD), a subvariant of fibrous dysplasia (FD), focusing on its clinical, pathological, and genetic characteristics.
- It included a cohort of 24 patients, confirming FCD diagnoses through various methods and identifying genetic mutations using Sanger sequencing.
- Findings revealed specific radiographic and histological features, alongside shared mutations in both fibro-osseous and cartilaginous components, confirming FCD as a variant of FD.

A taxonomic study of deep-sea polychaetes collected at a depth of 2,805 m off the northern coast of California revealed a scaleworm of the family Sigalionidae with an attached parasitic copepod. The copepod represents an undescribed genus of the family Herpyllobiidae, comprising mesoparasitic copepods chiefly recorded from polychaetes of the family Polynoidae. Blakerius gen.
