    Abstract:
    Porphyria cutanea tarda (PCT) may be associated with various neoplasma. Two additional cases are reported here. In the first case, a 58-year old alcoholic man had been presenting for two years with clinical signs of PCT. The diagnosis was confirmed by porphyrin assays in the urine. He also had cirrhosis of the liver. During a routine fibroscopy in search of oesophageal varices, a gastric adenocarcinoma was discovered by chance. Following partial gastrectomy the skin lesions of PCT improved dramatically within a few weeks, leaving only moderate cutaneous fragility. Urinary porphyrin assays performed 18 and 40 months after gastrectomy gave normal results, although no specific treatment had been prescribed. The second case concerns a 67-year old man, also alcoholic, with clinical and biochemical PCT. For the previous 12 months he had received chemotherapy (Adriamycin, then BCNU combined with melphalan, vincristine and prednisone) for multiple IgA K myeloma. The myeloma was active when PCT was diagnosed with, in particular, chronic anaemia. Treatment with chloroquine improved the cutaneous signs of PCT but had no effect on urinary porphyrins after 5 months. Comments PCT has been reported to be associated with cancers. The best known of these cancers is primary carcinoma of the liver (4, 27, 32), but its frequency is diversely evaluated depending on the diagnostic methods (e. g. patient autopsied or not) and on the selection of patients (age, duration of the disease).(ABSTRACT TRUNCATED AT 250 WORDS)
