Bone Located Centrally Within a Dermolipoma

Subconjunctival Fat Prolapse and Dermolipoma of the Orbit: Differentiation on CT and MR Imaging

“…This finding may represent the histologic feature of collagenous connective tissue contained within the stroma. Although there was a report of dermolipoma containing bone, 13 our series did not show any significant calcific bodies within the lesion on CT scans.…”

“…However, other studies as well as the present one support the isolated feature of dermolipoma. 1,13 On the basis of embryogenesis (ie, an ectopia of the ectoderm to the conjunctiva), it may be more usual to see dermolipoma in isolation from the orbital fat. In our study, CT scans showed subtle soft-tissue strands within 2 of 6 dermolipomas.…”

Epibulbar osseous choristoma with dermolipoma: A case report and review of literature

“…We conducted a systematic literature review on previously reported cases via PubMed using the keywords “congenital subconjunctival mass,” “epibulbar osseous choristoma” and “epibulbar dermolipoma.” Full-text, free-access, English-printed articles with pathologically confirmed epibulbar osseous choristoma and dermolipoma identified 14 cases (Table 1). [8,11–13,17–27] Including our case, age range at presentation was from birth to 38 years with mean age of 11.6 years. Ten cases (66.7%) were females, and 5 cases (33.3%) were males.…”

“…In review of literature, CT images of epibulbar osseous choristoma revealed a cystic mass with fat-like low-density and a high-density radio-opaque mass which is indicative of a calcium component. [8,11,12,[17][18][19][20][21][22][23][24]26] This differentiates epibulbar osseous choristoma from low-density lesions like fat, dermolipoma, or epibulbar dermoid and helps predict the diagnosis.…”
