[A woman with paraneoplastic dermatoses; signs of recurrent malignancy]. / Een vrouw met paraneoplastische huidafwijkingen; voorbode van een recidief van een maligniteit.

BACKGROUND: Paraneoplastic dermatoses may be the first manifestation of a malignancy. Rapid recognition is therefore important. CASE DESCRIPTION: A 72-year-old woman who had been treated in the past for metastasised neuroendocrine carcinoma and had undergone curative treatment for stage-1c endometrial carcinoma developed three paraneoplastic dermatoses over a 2-year period: acanthosis nigricans, tripe palms and acquired hypertrichosis lanuginosa. Half a year later, cutaneous metastases derived from the endometrial carcinoma treated 12 years prior were discovered. CONCLUSION: The development of three paraneoplastic dermatoses in a short period of time is rare. Acanthosis nigricans, tripe palms and acquired hypertrichosis lanuginosa can develop in association with both neuroendocrine and endometrial carcinoma. The sudden development of paraneoplastic dermatoses is frequently a forewarning of progression of the malignancy.

A 41-year-old man with metastases of a gastrointestinal stroma tumour was treated with an angiogenesis inhibitor. He presented with a distinct painful erythematous hyperkeratotic bullous hand-foot skin reaction. This was thought to be caused by the oral angiogenesis inhibitor and resolved after discontinuation of the therapy. This is a known adverse effect of angiogenesis inhibitors and is dose dependent.
