The second reported patient with simultaneous metastatic epidermoid carcinoma and chronic myelogenous leukemia is described. The difficulty of differentiating the leukemia from a leukemoid reaction is discussed. The incidence of, and importance of looking for, second primary cancers in patients known to have cancer is emphasized.

In summary, LAP is an intriguing enzyme and its control is related to pituitary-adrenal function. A review of the changes in LAP activity which occur in some physiological conditions and in disease states has been presented. The function of LAP, however, is unknown. Table I summarizes those conditions in which the LAP is consistently altered enough so to help in the diagnosis of the disorder. Of prime importance is the differentiation of CML from a leukemoid reaction or agnogenic myeloid metaplasia with a leukocytosis. However, in no instance is the LAP value alone diagnostic of any disease. It remains a laboratory test to be utilized in conjunction with all other available clinical data.

During the period between 1948-1963 a total of 3,200 tumor patients were treated in the First and Second Medical Clinics of Tg.-Mures. In these tumor patients as well as the skin cancer patients who were treated with radiotherapy the authors found in 1.5% of the patients a leukocytosis of more than 20,000. In the last ten years (1964-1974), however, in the Second Medical Clinic only, 5% of 516 tumor patients showed a leukocytosis exceeding 20,000. In the first group of patients (3,200 cases) 0.03% showed more than 50,000 leukocytes, in the other group of 516 patients 0.2% showed more than 50,000 leukocytes. These values point towards a leukemoid reaction. A shift to the left to the myelocytes or beyond in the blood picture was found in the Second Medical Clinic in 10% of patients with carcinoma during the year of 1974. In 6% of the cases erythroblasts in the peripheral blood were seen, too. This deviation occurred often independent of the total number of leukocytes and was of a temporary nature. During the same time (1949-1974) 128 patients with chronic myeloid leukemia were treated in both departments as in-patients. 6 cases (i.e., 4.6%) had a chronic myelosis simultaneous with carcinoma, in one case together with an osteosarcoma. The diagnosis was confirmed in all cases by autopsy.

A case of chronic granulocytic leukemia was diagnosed in a ten year old miniature poodle and was observed for four and one half years. Methods of diagnosis and characteristic features are described. A persistent granulocytosis with a preponderance of mature forms and the absence of a detectable underlying pyogenic process were key diagnostic features which enabled distinction of this neoplastic process from acute granylocytic leukemia and a leukemoid reaction. Other features included dysplastic granulocytes in various developmental stages, marginal anemia and hyperplastic bone marrow (myeloid elements). No blast crisis occurred. This dog was euthanatized in August 1975.

Reactive leukocytosis has been reported in patients with non-Hodgkin's lymphoma of different histologic types. On the other hand, the blastic crisis of chronic myelocytic leukemia (CML) can sometimes be localized outside the bone marrow and simulate lymphoma, particularly when the blasts are of lymphoid lineage and the blastic crisis is the presenting feature of the disease. We report two patients in whom the differential diagnosis between lymphoblastic lymphoma with reactive leukocytosis and blastic crisis of CML outside the bone marrow was raised. They were two males aged 32 and 22 years, respectively, with lymphadenopathy (and one with splenomegaly), who were initially diagnosed of T lymphoblastic lymphoma. In both cases, leukocytosis was detected with myelemia and dysgranulopoiesis in the onset in one of them and when lymphadenopathy reappeared after remission in the other one. In addition, one patient had marked eosinophilia. In the bone marrow there was marked granulopoietic hyperplasia, with a reduction of fatty cells, and the granulocyte alkaline phosphatase index was reduced. However, the cytogenetic study did not disclose the existence of Philadelphia (Ph) chromosome, and bcr/abl molecular rearrangement was also not observed in the molecular study of both cases. We discuss the basic aspects of differential diagnosis between T lymphoblastic lymphoma with leukemoid reaction and T lymphoid lymphadenopathic blastic crisis of Ph-negative, bcr/abl-negative CML.

A male patient, aged 78, was found with chronic neutrophilic leukemia (CNL). The patient showed sustained mature neutrophilic leukocytosis, splenomegaly, a high leukocyte alkaline phosphatase score, elevated serum vitamin B12 and uric acid, myeloid hyperplasia and absence of ph' chromosome in the bone marrow, with no evidence suggesting this condition to be a leukemoid reaction to an underlying disease. In addition to the above mentioned features, some functional characteristics of CNL cells were compared with normal cells. CNL is a very rare disease; some thought it as a variant of chronic myelogenous leukemia (CML). In this report a review of the literature is also included.

A case of leukemoid reaction associated with renal carcinoma is presented. On account of the high leukocyte count and a palpable abdominal mass in the upper left quadrant, interpreted as an enlarged spleen, the primary tentative diagnosis was chronic granulocytic leukemia. Abdominal ultrasonographic scan revealed an enlarged left kidney and subsequent nephrectomy revealed a large hypernephroma. Leukemoid reactions associated with malignant disease are described in general with emphasis on the differential diagnosis.

A case of lepromatous leprosy with erythema nodosum leprosum (ENL) presenting as a myeloid leukemoid reaction is reported. Very high leucocyte count with immaturity of the cells in myeloid series was present in peripheral blood. High leucocyte alkaline phosphatase score, absence of hepatosplenomegaly and transient nature of leukemoid reaction differentiated it from chronic myeloid leukemia and acute myeloblastic leukemia. The possible mechanisms of leukemoid reaction in ENL are discussed.

In vitro culture studies of peripheral blood leukocytes using semi-solid media from 8 patients with chronic granulocytic leukemia (CGL) and 5 patients with granulocytic leukemoid reaction were performed. A markedly increased number of circulating colony-forming units were present in patients with CGL (mean 343 +/- 47) as opposed to those having granulocytic leukemoid reaction (mean 7.0 +/- 4). The colony size was larger in CGL than in granulocytic leukemoid reaction or in normal peripheral blood.

A retrospective study was conducted to analyze the surgical aspects of the splenectomy in chronic myelogenous leukemia. Twenty patients, Philadelphia chromosome-positive, were initially treated with busulfan until remission was reached. Elective splenectomy was then performed and chromosomal studies repeated at four- and six-month intervals yielding the indication for cyclic intensive chemotherapy. There ws no mortality, one episode of gram-negative sepsis with shock, and five instances of minimal complications. The spleen weights averaged 265 g, ranging from 60 to 800 g. All patients had normal coagulation profiles at the time of surgery, but four of them developed a postoperative thrombocytosis without related complications. A specific correlation was noted between postoperative thrombocytosis and splenomegaly (average weight 570 g). Eleven patients showed a high postoperative leukemoid reaction (average 40,500 cells/cu mm). The interval between diagnosis and splenectomy was shorter (average 7.5 months) in this group than for the patients who had a lower granulocytosis (average 19.5 months).
