    Area of Science:

    • Dermatology
    • Oncology
    • Histopathology

    Background:

    • Eccrine poromas are benign adnexal neoplasms originating from the acrosyringium.
    • Multiple eccrine poromas are uncommon, and a linear arrangement is exceptionally rare.

    Observation:

    • A 44-year-old woman presented with multiple, 20-year-standing papular lesions on her right lower extremity.
    • The lesions exhibited a distinct linear pattern.
    • Histopathological examination revealed features of eccrine poroma with unusual extensions and epidermal attachments.

    Findings:

    • The tumor displayed thin, intertwining strands of cells extending into the dermis, reminiscent of premalignant fibroepithelioma.
    • Bud-like proliferations attached to the epidermis were noted, similar to superficial basal cell epithelioma.

  • Dilated cystic ducts, characteristic of syringoma, were observed in the upper dermis.

    • Implications:

    • This case highlights the potential for eccrine poromas to present with diverse histological patterns and unusual distributions.
    • The linear arrangement and overlapping features underscore the importance of thorough histopathological evaluation for accurate diagnosis.
    • This unique presentation expands the known clinical spectrum of eccrine poromas and may inform future diagnostic criteria.
