L G Silva, F N Brandão, F Paredes

    Medicina Cutanea Ibero-Latino-Americana
    |January 1, 1976

    Summary

    A rare case of a plantar "mixed tumour," a type of salivary gland tumor, was found in a 39-year-old woman. This foot lesion presented unusually with ulceration and features mimicking pyogenic granuloma or eccrine poroma.

    Area of Science:

    • Dermatopathology
    • Surgical Pathology
    • Oncology

    Background:

    • Plantar
    • mixed tumours
    • are rare salivary gland-type neoplasms presenting on the foot sole.
    • Diagnosis can be challenging due to their unusual location and presentation.

    Observation:

    • A 39-year-old female presented with a 15-month history of a painful, ulcerated nodule on her left foot sole.
    • Clinical examination suggested pyogenic granuloma or eccrine poroma due to location and appearance.
    • Unusual features included lesion depth and a tense, cystic palpation feel.

    Findings:

    • Microscopic examination revealed a
    • mixed tumour
    • of the salivary type with ductal differentiation.
    • No cartilage formation was observed, differentiating it from typical mixed tumors.
    • Literature review identified seven other plantar
    • mixed tumour
    • cases, none exhibiting ulceration or pyogenic granuloma-like features.

    Implications:

    • This case highlights the importance of considering rare salivary gland tumors in the differential diagnosis of plantar foot lesions.
    • The unusual presentation underscores the need for thorough histopathological evaluation to ensure accurate diagnosis and appropriate management.
    • Further research into plantar
    • mixed tumour
    • presentations may improve diagnostic accuracy and patient outcomes.
