To explain the marked variation in the reported incidence of how often leukemic cells infiltrate the eye in fatal cases of leukemia, we tested the hypothesis that ocular leukemic infiltration is related to the peripheral leukocyte count during the final hours of life. We reviewed tissue sections, as well as autopsy and clinical records, from 135 patients who had fatal leukemia and had their eyes examined after death at Duke University Medical Center. Infiltrates of leukemic cells were found in the eyes of 42 of 135 patients (31.1%), with the choroid being the most frequently involved site. We detected a significant positive correlation between the ocular leukemic infiltration and an agonal leukocyte count as well as the severity of systemic disease. Differences in the agonal circulating leukocyte count may partly explain variations in the incidence of leukemic infiltrates in different postmortem studies.

Two cases of meningeal invasion by non-myelomatous plasma cell dyscrasias--a plasma cell leukaemia and an extramedullary plasmacytoma--are described. Both were secretors of IgD paraprotein and both were diagnosed in life, characteristics which we have not found in any other published case of plasma cell leptomeningitis. Analysis of our patients and of another 25 cases suggests as predisposing factors of meningeal invasion the male sex, presentation in the form of plasma cell leukaemia, presence of the IgD paraprotein and tumoral involvement of pleura, lung, pericardium and testicles. Aggressive treatment of this neurological complication controlled the meningeal disorder in some cases. However, the majority died of disseminated disease in spite of systemic chemotherapy. Until an effective treatment can be found, able to maintain remission or cure the systemic disease, prophylaxis of the central nervous system in plasma cell dyscrasias does not appear to be advisable.

About half of the general population harbors Candida species in oral flora, and oral candidal infections are common. However, in immunocompromised or immunosuppressed patients, candidiasis may progress to life-threatening systemic disease. Patients with human immunodeficiency virus (HIV), acquired immunodeficiency syndrome, HIV disease, diabetes, or leukemia are particularly prone to serious systemic infection. Chemotherapy for cancer and bone marrow and organ transplantation also provide physiologic opportunities for candidal colonization. Topical therapy has the potential to prevent and treat candidiasis with less risk of side effects and drug interactions than systemic therapy. Among the effective topical agents are polyene antifungal antibiotics and imidazole compounds. Some of these agents have been found useful in prevention of serious candidal infection in high-risk patients; however, more study is needed in this area.

MR is the only noninvasive procedure that can demonstrate changes in the medullary space. If it is combined with bone marrow scintigraphy and conventional x-ray film diagnostics, it can yield a comprehensive diagnosis of bone marrow infiltrations in the regions of the pelvis, thighs and lumbar vertebral column in leukaemia or malignant lymphomas. The T1 relaxation times of the malignant infiltrations are enhanced compared with normal fatty marrow. MR tomography of the bone marrow is particularly suitable for determining the therapy or follow-up control of a malignant systemic disease.

An unusual presentation of a case of myeloblastoma (granulocystic sarcoma, chloroma) as demonstrated by computed tomography (CT) and selective angiography is reported. Our patient, who presented with acute hydrocephalus due to a large posterior fossa myeloblastoma, had no evidence of systemic disease in either peripheral blood smear, bone marrow aspiration, lumbar puncture or further metastatic workup. While no evidence for generalized disease was seen, systemic chemotherapy may help to prevent overt systemic leukemia.

The clinicopathological features of 34 patients with malignant lymphoma or leukaemia where the initial presentation was as an ovarian tumour are described. Nineteen patients died, usually within 1 year of diagnosis, whilst 15 survived, some for long periods. Factors indicating a poor prognosis were rapid onset of abdominal symptoms, the presence of systemic symptoms, bilateral ovarian tumours, advanced stage and a histological pattern other than that of a B-cell lymphoma. For staging purposes the Ann Arbor method appeared a more sensitive prognostic indicator than did the FIGO staging system. It is suggested that primary malignant lymphomas of the ovary are extremely rare and that for therapeutic purposes all lymphomas of the ovary should be regarded as local manifestations of systemic disease.

This report describes an unusual case of bilateral metachronous granulocytic sarcoma of the breast. The patient initially did not have evidence of leukemia and her marrow cell culture in soft agar (CFU-C array) showed normal in vitro growth pattern. The patient was treated with systemic chemotherapy at a time when there was no evidence for systemic disease but she nevertheless developed meningeal leukemia and bone marrow disease 11 and 18 months, respectively, following the initial chemotherapy.

A granulocytic sarcoma expanded the malar region in a patient with proven myelofibrosis over a 22 month period before undergoing rapid increase in size concomitantly with transformation to acute granulocytic leukaemia in the marrow and the widespread appearance of subcutaneous tumour deposits. Rapid response was obtained with local radiotherapy, and the systemic disease manifestations were controlled on combination courses of oral 4'-demethoxydaunorubicin and the epipodophyllotoxin VP16-213. This appears to be the first example of a granulocytic sarcoma occurring in a patient with myelofibrosis.

Pyoderma gangrenosum is a rare occurrence in patients with haematological malignancy. This characteristic but nonspecific inflammatory process with skin destruction occurred in 4 patients with myelodysplasia, in one with acute leukaemic transformation of myelofibrosis, and in de novo acute myeloblastic leukaemia in another. Clinically, the cutaneous lesion in these patients differed from that associated with inflammatory bowel disease, arthritis, or the idiopathic type of pyoderma gangrenosum by having the vesiculo-bullous borders. Histopathological differences were also evident since more superficial layers of the skin were involved in the ulceration than typically encountered in patients with non-malignant systemic disease. Despite the less penetrating nature of this variant, treatment of the pyoderma gangrenosum is unsatisfactory and in the absence of effective therapy for the underlying disease, healing occurred only in the patient with acute leukaemia who achieved complete remission in response to chemotherapy.

The course of a hemopathy may be characterized by the appearance of cutaneous lesions. In such cases a correct histological investigation is needed, especially when the lesions have an aspecific appearance. It is important, therefore, to recognize the cases characterized by cutaneous involvement of typical systemic disease cells. Lymphomas and leukemias are the hemopathies which more frequently present specific and nonspecific cutaneous manifestations (with an approximate incidence of 3-40 and 6-50%, respectively). In the period 1977-1983 we examined 337 patients affected with acute nonlymphoblastic leukemia and 243 patients affected with non-Hodgkin lymphoma, in order to verify the incidence of specific cutaneous manifestations.
