ABSTRACT
We describe a patient with a long history of skin lesions clinically and histologically consistent with epidermodysplasia verruciformis (EV) who developed malignant thymoma. HPV-9DNA was found in the macular lesion and HPV-4DNA and HPV-9DNA in the coexistent common warts. Thrombocytopenia and hypogammaglobulinaemia preceded the diagnosis of thymoma. Our patient seems to represent an example of an EV-like syndrome in immunodeficiency.

A patient with a megakaryocytosis associated with a Philadelphia chromosome-positive chronic myeloid leukemia (CML) was found to have a trisomy of chromosome five. To our knowledge, this is the first case of trisomy 5 associated with a Ph + CML, particularly one with a megakaryocytosis. The trisomy 5 may be associated with the resistance to cytostatic drugs found in this patient.

One thousand four hundred sixty patients with 2,590 patient-years of follow-up were treated on 15 protocols for metastatic breast cancer with dibromodulcitol (mitolactol; DBD)-containing regimens since 1976. Twenty-three patients developed myelodysplastic syndrome (MDS) and/or acute nonlymphocytic leukemia (ANLL). The overall risk of developing MDS or ANLL per person is 1.6%. In patients who had received more than 16,000 mg of DBD the risk per person is 6%, and in the high-dose subsets of patients who received no prior radiation or alkylator therapy, it is 7.9%. The risk per person increases to a maximum by 30 to 36 months (5.3%). The high risk was seen despite a study population of metastatic breast cancer patients with a median survival of 16 months. This analysis strongly suggests that DBD is one of the most potent of the reported leukemogenic-inducing agents. Further use of this drug in both the adjuvant and metastatic situation should be reconsidered.

A patient with scleromyxoedema was treated for 6 years with cytostatic drugs. During this time the skin lesions followed a fluctuating but progressive course. After 6 years she developed Hodgkin's lymphoma of the mixed cellularity type. Intensive cytostatic treatment given for Hodgkin's disease resulted in virtually complete disappearance of the scleromyxoedema lesions. The development of Hodgkin's disease is considered fortuitous and not due to the previous cytostatic drugs.

Forty-six patients with acute leukemia were treated with mitoxantrone as a single agent. Twenty-nine patients had relapsed and/or refractory acute leukemia. Seventeen patients with acute non-lymphatic leukemia had received no prior treatment. Twelve mg/m2 of mitoxantrone was given intravenous on five consecutive days. Treatment related side effects included bone marrow suppression, mucositis, alopecia, nausea, vomiting and infection. Cardiotoxicity was documented in 7 patients. This study reconfirms that mitoxantrone is an active agent in acute leukemia with complete response documented in 10 of 29 patients with relapsed and/or refractory acute leukemia (34% response rate, 95% confidence limits 18-53%) and complete response documented in 11 of 17 patients (65% response rate, 95% confidence limits 38-87%) with previously untreated acute nonlymphatic leukemia.

The history and findings in a patient with erythroleukaemia who developed a fungal brain abscess during the agranulocytic phase of induction treatment is reported. The radiological features of fungal infection are reported, with emphasis on the importance of clinical judgement in making the diagnosis. The autopsy findings further illustrate the increasing importance of this previously very rare condition.

Twenty-six previously untreated patients with acute non-lymphocytic leukemia (ANLL) were treated with oral idarubicin and cytosine-arabinoside (Ara-C). The median age of the patients was 44 years (range, 11-72). In 23 of the 26 patients a hypoplastic marrow, with a peripheral white cell count of less than 1,000/mm3 after treatment, was documented. Treatment was well tolerated with minimal symptoms of nausea and vomiting. Diarrhea was observed in three patients and stomatitis in nine patients. Alopecia was documented in only six patients. A complete remission (CR) was obtained in 12 patients (median duration 25 weeks). The median time to CR was 3.4 weeks (range, 1.4-5). Ten of the 26 patients were alive 6 months after the start of induction treatment, while a further four patients who were in the study for less than 6 months are alive and in remission at 5, 4, 3, and 3 months, respectively. Eight of 12 patients in whom bone marrow aplasia was documented achieved a CR; perhaps the drug dosages used in this study were suboptimal.
