Abstract

Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin. These nodules are formed by the deposition of lamellar bone and are characterized by osteocytes in the core and osteoclasts around the periphery. Interpretation of osteoma cutis cases has always been challenging especially using conventional two-dimensional (2D) radiographs, owing to difficulty in localization. Cone beam CT (CBCT), with its three-dimensional (3D) capabilities, offers a great tool to help detect and diagnose these calcific entities. We report a case of miliary type OC incidentally detected in the maxillofacial region using CBCT imaging.

Highlights

Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin [1]
The aim of this study is to describe a case of miliary osteoma cutis incidentally detected in the maxillofacial region using Cone beam CT (CBCT) imaging
Multiple small round nodules of homogenous high density were noted. They appeared to be evenly dispersed within the thin layer of skin of the face (Figure 2). These imaging features are most consistent with miliary type OC, which presents as numerous lesions especially on the face of female patients

Summary

Introduction

Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin [1] These nodules are formed by the deposition of lamellar bone and are characterized by osteocytes in the core and osteoclasts around the periphery [2]. Safi et al in a recent publication reported the prevalence of osteoma cutis as an incidental finding detected on CBCT to be 2.27% [10]. They classified the imaging appearance of osteoma cutis into four distinct categories: single nodular, plate-like, transepidermal, and multiple miliary. The aim of this study is to describe a case of miliary osteoma cutis incidentally detected in the maxillofacial region using CBCT imaging
