    A rare lentigo maligna melanoma was found on the glans penis. Fluorescence microscopy aided in identifying atypical pigmented cells, confirming the lentigo maligna diagnosis.

    Area of Science:

    • Dermatopathology
    • Oncology

    Background:

    • Melanoma diagnosis can be challenging, especially in rare locations.
    • Distinguishing between melanoma subtypes requires precise histopathological evaluation.

    Observation:

    • A case of lentigo maligna melanoma on the glans penis and urethral opening is presented.
    • Clinical differential diagnoses included superficial spreading melanoma and lentigo maligna.
    • Microscopic examination revealed atypical, heavily pigmented, dendritic cells in the basal epidermis.

    Findings:

    • Light microscopy showed isolated pigmented dendritic cells.
    • Fluorescence microscopy clearly identified dendritic branching in atypical pigment cells, confirming lentigo maligna.

    Implications:
