The "vanilla fudge" cyst.

E Young, N Orentreich, A B Ackerman

    Cutis
    |October 1, 1976
    PubMed
    Summary

    This study describes a unique white cyst with black pigment, resembling ice cream. Histological analysis revealed two distinct epithelial linings and melanin-producing melanocytes in a specific region.

    Area of Science:

    • Dermatopathology
    • Histology
    • Melanocyte Biology

    Background:

    • Cysts can present with varied histological features.
    • Follicular epithelium exhibits distinct regional differentiation.

    Observation:

    • A white cyst with black pigmentations was observed.
    • The cyst surface resembled vanilla fudge ice cream.
    • Histological examination revealed dual epithelial linings.

    Findings:

    • The cyst lining comprised two distinct follicular epithelial types: infundibular and matrix-like.
    • The black pigment was identified as melanin.
    • Dendritic melanocytes producing melanin were localized to the matrix-resembling epithelium.

    Implications:

    • This finding expands the understanding of follicular cyst histopathology.
    • It highlights the potential for melanogenesis within specific cyst lining regions.
    • Further research may elucidate the developmental origins of such unique cyst formations.
