GENITAL VARIANT OF FOLLICULOSEBACEOUS CYSTIC HAMARTOMA

Background: Clinically, folliculosebaceous cystic hamartomas (FSCH) pr esent as skin-colored papulonodules of the face, especially the nose. This is in contrast to sebaceous trichofolliculomas which often presen t as depressed ostia containing terminal or vellus hairs. Observation: A 34-year-old female had a skin-colored multinodular plaque of the la bia majora that demonstrated the histologic findings of an FSCH. These included an irregularly shaped central cystic structure surrounded by multiple sebaceous lobules as well as a fibrous stroma. The epithelia l-lined cyst contained no hair shafts. Conclusion: A single case repor t of a scrotal lesion with a similar clinical appearance and histologi c findings has previously been described as a genital variant of sebac eous trichofolliculoma. However, the report predated the initial descr iption of FSCH. In our opinion, both cases represent examples of the g enital variant of FSCH.
