Epidermotropic metastases from squamous cell carcinoma of the lower female genital tract mimicking primary Bowen's carcinoma.

Epidermotropic metastases from internal malignancies are exceedingly rare. We report a striking example of epidermotropic metastatic carcinoma of the lower female genital tract to the skin of the abdomen and groin. Atypical cells were scattered throughout the epidermis, mimicking Bowen's disease.

'Specific' cutaneous infiltrate of B-cell chronic lymphocytic leukemia at the site of a florid herpes simplex infection.

Background: Specific cutaneous infiltrates in patients with leukemia generally carry a grim prognosis. However, non-neoplastic skin diseases may be associated with recruitment of normal and neoplastic leukocytes circulating in the peripheral blood. In those instances, neoplastic cells may be detected in skin lesions without an adverse effect on prognosis.
