    This case study details malignant acanthosis nigricans (AN) linked to cervical squamous cell carcinoma. The rare condition unusually affected the conjunctiva and widespread skin and mucosal surfaces.

    Area of Science:

    • Oncology
    • Dermatology
    • Gynecologic Oncology

    Background:

    • Malignant acanthosis nigricans (AN) is a rare paraneoplastic syndrome.
    • It is often associated with underlying visceral malignancies, particularly adenocarcinomas.
    • Squamous cell carcinoma, especially from the cervix, is an infrequent cause of AN.

    Observation:

    • A patient presented with generalized malignant acanthosis nigricans.
    • Initial lesions resembled condyloma acuminatum on the perineum.
    • The condition progressed to involve extensive cutaneous surfaces and mucosal linings, including the vulva, oral cavity, tongue, and palpebral conjunctiva.

    Findings:

    • The patient's AN was secondary to a metastasizing squamous cell carcinoma of the cervix uteri.
    • The widespread mucocutaneous and unusual conjunctival involvement highlight the aggressive nature of the malignancy.

    Related Experiment Videos

  • This case underscores the rare association between cervical squamous cell carcinoma and generalized AN.

    • Implications:

    • This presentation expands the known clinical spectrum of malignant acanthosis nigricans.
    • It emphasizes the importance of considering gynecologic malignancies in patients with unexplained mucocutaneous changes.
    • The unusual conjunctival involvement warrants further investigation into potential mechanisms and diagnostic significance.
