This investigation describes the clinicoradiologic, pathologic, and molecular features of a unique soft tissue tumor characterized by a peripheral shell of bone and composed of bland myoid spindle and epithelioid cells that are keratin-positive. Our study cohort consists of 6 men and 6 women, with a mean age of 32 years. The tumors arose in the extremities (n = 9) and proximal limb girdle (n = 3) and were equally distributed between deep and superficial soft tissues.

Amelanotic melanocytic nevi of the oral cavity are uncommon lesions that often present a diagnostic challenge for clinicians, primarily due to their nonspecific clinical appearance and the broad spectrum of possible differential diagnoses. These lesions can mimic a variety of benign and malignant conditions, requiring precise histopathological confirmation. The primary objective of this article is to present a comprehensive case report-tracing the course from initial presentation through diagnostic workup to final diagnosis-and to provide an overview of the current literature on oral amelanotic melanocytic nevi.

Pyogenic granuloma (PG) is a benign vascular lesion that manifests as an inflammatory hyperplasia of the skin or mucous membranes. Although termed "pyogenic," PG is not associated with infection; rather, it represents a reactive lesion arising in response to various stimuli such as low-grade local irritation, trauma, or hormonal influences. Clinically, PGs are typically asymptomatic and display variable growth rates.

Ossifying fibromyxoid tumors (OFMTs) are rare mesenchymal neoplasms with behaviors ranging from benign to malignant. Although most occur in the extremities and trunk, 9-13% are found in the head and neck, such as the oral cavity, scalp, and calvarium. Diagnosis is challenging due to their rarity and histological similarity to other neoplasms.

Introduction: Ameloblastic fibroma (AF), ameloblastic fibrodentinoma (AFD), and ameloblastic fibro-odontoma (AFO) are rare mixed odontogenic tumors. While some authors propose that some cases may evolve into odontomas, other tumors with aggressive clinical features suggest a neoplastic origin. A subset of AF and AFD/AFO harbor the pathogenic BRAF p.
