Xeroderma pigmentosa in siblings: cystosarcoma phylloides in a case of xeroderma pigmentosa.

Xeroderma pigmentosa is a rare autosomal recessive disorder with numerous oculocutaneous neoplasms, neurological abnormalities and extremely rarely associated with neoplasms of organs other than the skin and the eyes. Here we report two cases of xeroderma pigmentosa with numerous oculocutaneous malignancies in siblings born to a consanguinously married normal parents. One of these patients had a cystosarcoma phylloides in association with xeroderma pigmentosa, hitherto not reported in literature.
