Serpentine supravenous hyperpigmentation induced by the nitrosourea fotemustine.

Two cases of serpentine supravenous hyperpigmentation developing in the area of fotemustine infusions are reported. Histological features showed an increased melanin synthesis and the presence of melanophages without focal degeneration of basal cells or dermal inflammatory infiltrate. Perls' strain was negative. Hypotheses concerning the mechanisms of increased melanin synthesis over the veins are discussed.

Extraocular sebaceous carcinoma.

A 79-year-old man with no history of previous irradiation presented with a large ulcerated tumour of the cheek. The histological features favoured a true sebaceous carcinoma. Neither squamous nor basal differentiation were seen. Sudan stainings were positive. Tumour cells expressed suprabasal keratins and were negative for carcinoembryonic antigen, vimentin and S 100 protein. Extraocular sebaceous carcinomas occurring without previous irradiation are rare tumours which behave aggressively. Treatment regimens are discussed.
