A 5-year-old, intact male, stray dog was presented in poor body condition, with pallor, muzzle deformity, multiple oozing fistulas with grass awns, bilateral sanguinopurulent nasal discharge and a fleshy friable mass occupying part of the hard palate. A friable mass occupying both nasal cavities was found on rhinoscopy. The dog had moderate nonregenerative normochromic-microcytic anemia, thrombocytopenia, hyperglobulinemia, and hypoalbuminemia. Cytologic preparations of the nasal and oral masses contained a neoplastic population of round cells with intracytoplasmic and extracellular vacuoles. Leishmania amastigotes also were observed, in the cytoplasm of macrophages and, occasionally, within neoplastic cells. A diagnosis of transmissible venereal tumor and concurrent leishmaniosis was made. Treatment with vincristine and allopurinol resulted in complete resolution of clinical signs and disappearance of the masses. The presence of amastigotes in neoplastic TVT cells may suggest an alternative mode of transmission of canine leishmaniosis where these diseases co-exist.

We present a case report that the patient had symptoms suggesting pheochromocytoma, a large tumor (> 50 g) and a single minimally altered laboratorial test, exemplifying a diagnostic pitfall. A 31 y.o. male patient had two acute abdominal events, the last one accompanied by headache, arterial hypertension, facial flushing, perspiration and cutaneous pallor. In another admission, the patient had sustained arterial hypertension and cardiac arrhythmia. From laboratory analysis, the vanililmandelic acid was slightly modified. Scintigraphy disclosed a large adrenal mass suggesting pheochromocytoma. Histopathology confirmed this hypothesis. This report points out that patients with symptoms suggesting pheochromocytoma, even when plasma catecholamines and urinary metanephrines levels are normal, may harbor large tumors with a high catecholamines turnover or that had undergone hemorrhagic necrosis.

The present patient was a 50-year-old male with sudden upper abdominal pain. The patient exhibited pallor, and physical examination revealed a rigid abdomen. Abdominal x-ray revealed free air, and emergency laparotomy was performed to confirm upper gastrointestinal tract perforation. A perforated lesion of approximately 1 cm in diameter was found on the anterior wall at the gastric angle. The area surrounding the lesion was tumor-like, and the posterior wall was fused invasively with the pancreas. Malignancy was suspected; however, considering the patient's general status, greater omentum grafts were opted for. The patient was diagnosed with type III gastric cancer by gastroendoscopy post-operatively, and TS-1/CDDP therapy was started on the 28th day after surgery. After three courses of treatment, the tumor was found to have smoothened, wall consolidation was improved, and a second surgery was performed. During laparotomy, a nodule in the round ligament of liver was found and removed; however, there were no other medical findings that raised suspicion of peritoneal dissemination or liver metastasis. It was concluded that radical surgery was possible, and distal gastrectomy (D 2) was performed. Pathological examination revealed that signet ring cell carcinoma was present on only part of the mucous membrane. The lower and muscle layers of the serous membrane and the nodule in the round ligament of liver were replaced by fibrous tissue, indicating the disappearance of cancer cells. Two years and three months after surgery, the patient exhibited no signs of recurrence.

A 12-year-old, male black and white colobus monkey (Colobus guereza kikuyuensis) from a small community zoo presented with a 6-month history of mild, slowly progressive ataxia and paresis culminating in an acute episode of recumbency, depression, and seizures. The animal was humanely euthanatized. Gross post-mortem examination revealed significant abnormalities including diffuse pallor of the carcass and a firm, pale, 8-cm diameter mass, adherent to the serosa of the proximal duodenum and colon, and embedded within the pancreas and mesenteric root. Histologically, the mass had characteristics of a neuroendocrine or endocrine tumor. Immunohistochemical stains for chromogranin, synaptophysin, insulin, and glucagon were positive, confirming the diagnosis of a mixed pancreatic islet cell tumor. These tumors are rare in all species except ferrets and unreported previously in colobus monkeys.

A 21-month-old girl was admitted to our Department of Pediatrics to diagnose febrile states lasting for previous two weeks, anemia and increased erythrocyte sedimentation rate (ESR - erythrocyte sedimentation rate). The physical examination revealed the paleness of skin and oral mucosa, silent systolic murmur and hypotrophic constitution. The laboratory tests confirmed anemia and showed increased ESR and moderately increased C Reactive Protein (CRP - C Reactive Protein). The blood culture, the urine culture, the stool culture, the tests of the stool in direction of parasites and the serologic tests carried out in direction of infection caused by Toxoplasma ghondi, Mycoplasma pneumoniae, HAV, HCV, CMV, EBV and Parvovirus B19 were all negative. The chest X-ray picture and ultrasonographic examination of abdomen showed no abnormality. The consulting hematologist carried the bone marrow biopsy out--the bone marrow was poorly cellular. The urinary level of catecholamines and plasma level of neuron-specific enolase (NSE) were greatly increased. The computer tomography scan of head, neck, thorax and abdomen did not confirmed the presence of the tumor. Nevertheless the bone scintigraphy demonstrated the presence of foci of abnormally increased activity in left femur and the right hip-bone--pathognomonic of metastatic disease. During the hospitalization we did not observe the fever, but only the deepening anemia, weakness, irritability, limping and the presence of spectacle-shaped hematomas. The blood parameters temporarily were normal after blood transfusion. The patient was transmitted to the Department of Children's Oncology and Hematology. The trepanobiopsy of the bone marrow showed the presence of metastases of neuroblastoma. The magnetic resonance imaging (MRI) was made, but it did not revealed the presence of the primary tumor. The patient underwent a course of chemotherapy.

An 8-year-old boy presented with a lifelong history of a vascular mass overlying his right mandible with central coarse telangiectasias and peripheral pallor. Histopathologic examination showed a proliferation of blood vessels in the dermis. Ultrasound examination identified a mix of high- and low-flow vessels within the lesion. These findings were consistent with a noninvoluting congenital hemangioma, a rare vascular tumor that is fully formed at birth that subsequently grows proportionately with the patient and does not regress.

The characterization of leukemia-associated chromosome translocations has contributed relevant insights into our understanding of leukemia pathogenesis and has provided new specific tumor markers essential in prognostic assessment and minimal residual disease studies. The aim of this work is to study the frequency of AML1/ETO fusion gene in a series of Egyptian childhood AML cases. The clinical significance and prognostic implications of this aberration, including CR rate, duration of first CR, extramedullary leukemia (EML), and survival are investigated as well. Peripheral blood and/or bone marrow mononuclear cells were available for analysis from 78 children, all newly diagnosed with AML. AML1/ ETO fusion transcript was detected by the reverse transcriptase- polymerase chain reaction (RT-PCR) technique. Patients with de novo AML were treated by 2 courses of induction chemotherapy, followed by 4 courses of consolidation treatment if the patient achieved complete remission (CR). The marrow status was evaluated after each course in order to check bone marrow cellularity and presence of blasts. Patients with less than 5% blasts by the end of the second course of ADE passed to consolidation chemotherapy. Patients with more than 5% blasts by the end of the second course of ADE were excluded from the study. The AML1/ETO fusion transcript was detected by a singleround RT-PCR reaction and was found to be expressed in 15 out of 78 cases (19.2%). AML1/ETO positive patients were 7 girls and 8 boys, with ages ranging from 5 to 15 years. Seven cases (46.67%) belonged to FAB subtype M1, 7 (46.67%) M2, while only one case (6.67%) belonged to M5a subtype. Their total leukocytic counts ranged from 7.1 to 183.0 x 109/l with a median of 21.0 x 109/l. Their hemoglobin concentrations ranged from 4.8 to 10.3g/dl with a median of 7.4g/dl, while their platelet counts ranged from 6.0 to 96.0 x 109/l with a median of 25.5 x 109/l. Lymph nodes were enlarged in 8/15 cases (53.34%), hepatomegly was observed in 4/15 cases (26.67%), splenomegaly in 8/15 cases (53.34%), purpura in 6/15 cases (40%), while pallor was observed in all fifteen cases.Extramedullary leukemia occurred in 4/15 cases (26.67%). As regards the fate of the positive cases, thirteen cases (86.67%) attained complete remission (CR) following induction chemotherapy. Two patients (13.33%) died during induction in active disease. Eight patients were in complete continuous remission (CCR), four patients (26.67%) relapsed and died during relapse, and one patient (6.67%) died in complete remission due to severe neutropenia and infection. On comparing the AML1/ETO fusion gene status with overall survival, no significant difference was found between AML1/ETO positive and negative cases. Likewise, no difference could be found between positive and negative cases as regards disease-free survival (p=0.354). In conclusion, we report a frequency of 19.2% of AML1/ETO fusion gene in our newly diagnosed pediatric AML cases. Positive cases showed good response to induction therapy, as well as high complete remission rates, which are features of good prognosis.

Adult T-cell leukaemia/lymphoma (ATLL) is a rare T lymphoproliferative disorder which is aetiologically linked with human T-cell lymphotropic virus type-1 (HTLV-1). HTLV-1 is endemic in Japan, Caribbean and Africa. The highest incidence of ATLL is in Japan although sporadic cases have been reported elsewhere in the world. We describe a case of ATLL with an unusual presentation which we believe is the first reported case of ATLL in Malaysia based on our literature search. A 51-year-old Indian lady was referred to University Malaya Medical Centre for an incidental finding of lymphocytosis while being investigated for pallor and giddiness. Clinical examination revealed bilateral shotty cervical lymph nodes with no hepato-splenomegaly or skin lesions. Laboratory investigations showed absolute lymphocytosis (38 x 10(9)/L) with a mildly increased serum lactate dehydrogenase. The peripheral blood smear showed the presence of predominantly small to medium sized, non-flower lymphocytes. The bone marrow showed similar findings of prominent lymphocytosis. Immunophenotyping of the bone marrow mononuclear cells showed CD3+, CD4+, CD5+, CD7- and CD25+ which is characteristic of ATLL phenotype. HTLV-1 infection was confirmed by the presence of HTLV-1 proviral DNA in the tumor cells using conventional Polymerase Chain Reaction (PCR) and real-time PCR. Here, we discuss the pathogenesis and characteristics of ATLL as well as the detection of HTLV-1 by real time PCR.

Thrombotic microangiopathy occurs in 5-10% of patients with mucin-producing disseminated adenocarcinoma. A 28-year-old woman complained of fatigue, bone pain, and weight loss. There were pallor, icterus, and tenderness in the bones on physical examination. Microangiopathic hemolytic anemia, leukoerythroblastic picture, thrombocytopenia, and normal coagulation tests were detected. Thrombotic thrombocytopenic purpura (TTP) was diagnosed and therapeutic plasma exchange was performed on the patient. On day 5 a laparotomy had to be performed because of acute abdomen due to the rupture of a corpus hemorrhagicum follicle of an ovary. Signet ring cell adenocarcinoma stained with cytokeratin 7 and mucicarmine was seen on ovaries and bone marrow, after the pathological examination. The primary site of tumor could not be investigated, because of the patient's refusal. Although chemotherapy including cis-platinum, infusional 5-fluorouracil, and calcium leucovorin were administered in two courses, she died from respiratory failure. In conclusion, malignancy and bone marrow involvement should be considered when associated with leukoerythroblastic picture and TTP.

Granular cell tumours are uncommon lesions, although the head and neck region accounts for approximately 50% of all lesions. It is not clear whether or not granular cell tumour is a true neoplasm, a developmental anomaly, or a trauma-induced proliferation. The basic cell of origin is now thought to be neural, although past reports frequently indicated an origin from striated muscle, or less frequently an origin from histiocytes, fibroblasts or pericytes. The tongue and the buccal mucosa are common intraoral sites. The other head and neck site likely to be involved is the larynx. The tumour generally occurs in middle or older aged adults. More than a third of all granular cell tumours occur on the lingual dorsum, usually as a sessile, painless, somewhat firm, immoveable nodule less than 1.5 cm in greatest diameter. Lesions often demonstrate a pallor or a yellowish discolouration and typically have a smooth surface. Histochemical and ultrastructural studies propose the origin of the lesion from Schwann cells, striated muscle, mesenchymal cells, histiocytes and epithelial cells. As most of the granular cell tumours are benign, surgical excision of the lesion is the treatment of choice.
