Background: Calretinin is a 29 kilodalton (KDa) calcium-binding protein that is expressed in normal and tumoral tissues. The expression of calretinin has been shown in the dental epithelium during odontogenesis and in different odontogenic cysts and tumors such as ameloblastoma. Since the epithelium of calcifying odontogenic cyst (COC) is similar to ameloblastoma and in both lesions, an arrangement of loose cells similar to stellate reticulum is seen, we aimed to investigate the comparative expression of calretinin in COC and ameloblastoma.

A calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic tumour of epithelial origin accounting for approximately 1% of all odontogenic tumours. The intraosseous form occurs more commonly in the posterior mandible whereas the extraosseous form is common in the anterior maxilla. CEOT is often asymptomatic and presents with a painless swelling of the mandible.

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic epithelial tumor characterized by the presence of amyloid material within the tumor that can undergo calcification. CEOT affects individuals across a broad age range, typically between 20 and 60 years, with an average onset age of 40 years. However, it is extremely rare in children and adolescents.

Background: Hybrid Odontogenic Tumors (HOT) are defined by the presence of two or more independent odontogenic tumors that originate from and affect the same maxillofacial site.
Methods: The present study is the first case report of a mandibular HOT consisting of Ameloblastoma, Calcifying Epithelial Odontogenic Tumor, and Ameloblastic Fibroma.
Case Report: A 37-year-old otherwise healthy male presented with the chief complaint of swelling in the right mandibular body.

Pilomatrix carcinoma (PC) is a rare malignant adnexal tumor originating from follicular matrix cells primarily impacting Caucasian males. This review provides a comprehensive analysis of scientific literature on PC through an exploration of 206 cases reported between 1980 and 2024. We discuss the epidemiology, clinical presentation, histopathology, and diagnostic challenges of PC, and explore various treatment methods for this rare malignancy as well as their associated outcomes.
