Abstract
Pulmonary tumor thrombotic microangiopathy syndrome is a rare clinicopathological entity in which tumor cell micro-emboli in the pulmonary microcirculation induced thrombotic microangiopathy. This can cause respiratory failure, and acute or sub-acute right heart failure. Histological features include micro tumor emboli in the small arteries and arterioles of the lung associated with thrombus formation and fibro-cellular and fibro-muscular intimal proliferation. The diagnosis is however extremely difficult to make before death. Thus, most of the observations reported are based on autopsy data. Very rare diagnostic observations made before death suggest the potential effectiveness of chemotherapy. Many details remain to be elucidated, interdisciplinary research is a priority with close collaboration between pathologists and clinicians to better understand this, often fatal, syndrome. It may be that the use of targeted therapies will improve the very poor prognosis allowing survival of several weeks or months after diagnosis.

Abstract
Pulmonary tumor thrombotic microangiopathy (PTTM) is known as a rare and severe cancer-related pulmonary complication. Nowadays, fewer than 80 cases have been reported in the literature and very few cases have been diagnosed antemortem. We describe an autopsy case of PTTM associated with cancer of unknown origin. A 56-year-old male patient came to our attention due to a 2-day history of dyspnea. Analysis of the clinical context in combination with laboratory and imaging tests led us to suspect acute pulmonary thromboembolism. However, the computed tomography pulmonary angiogram was negative for thromboembolism; on the contrary it revealed multiple lymphadenopathy. Microscopic pulmonary tumor embolism was suspected and a lymph node biopsy was planned. However, the patient's condition progressively worsened; death occurred 3 days after admission. After autopsy, histologically extensive neoplastic emboli involved the small pulmonary arteries and arterioles, often admixed with fibrin thrombi. The involved and noninvolved arteries also demonstrated fibrocellular intimal proliferation causing marked luminal stenosis and occlusion. These pathological features were characteristic of PTTM, which should be distinguished from microscopic tumor embolism and should be considered in the differential diagnosis of acute/subacute cor pulmonale and pulmonary hypertension in cancer as well as in noncancer patients. We propose a review of the literature and an algorithm to improve PTTM antemortem diagnosis.

Abstract
Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare clinicopathological entity causing severe pulmonary hypertension (PH). Its histological features include widespread tumor emboli of the small arteries and arterioles of the lung, associated with thrombus formation and fibrocellular and fibromuscular intimal proliferation. Although PTTM has drawn increased attention as a fatal complication of gastric carcinoma (GC), comprehensive studies are still lacking. In order to clarify clinical and pathological features of GC-induced PTTM, recent autopsy cases were analyzed with a review of the literature. Of 36 autopsy cases with GC, 6 (16.7%) were affected by PTTM. Four were male and 2 female, with a mean age of 72.7 years. Three patients presented with PTTM-related clinical manifestations and died of PTTM. They showed clear morphological evidence of PH. The other 3 patients had PTTM as an incidental finding irrespective of clinical manifestations or PH. No patient was diagnosed antemortem as PTTM. All PTTM cases were associated with advanced GC, with a histology of adenocarcinoma of poorly differentiated type (n=4) or signet-ring cell type (n=2). Expression of tissue factor and vascular endothelial growth factor was confirmed immunohistochemically in tumor cells in all cases. The results were all in line with previous studies. In addition, the current study revealed vascular lesions characteristic of PTTM morphology to be present exclusively in the lung. In conclusion, our study shows a 16.7% incidence of PTTM in GC patients, with half of them developing PH and dying of PTTM, confirming a clinical significance as a non-negligible lethal complication of GC. In addition to many known clinicopathological characteristics of PTTM, the current study pointed to some PTTM issues requiring clarification, including the pathogenesis of the exclusive pulmonary distribution of vascular lesions of PTTM. Since details remain to be elucidated, interdisciplinary research is a high priority with a close collaboration between pathologists and clinicians in order to overcome this lethal condition.

Abstract
Anaplastic large cell lymphoma (ALCL) is an aggressive neoplasm of T- or null cell phenotype and is recognized as a distinct clinicopathologic subtype of non-Hodgkin lymphoma (NHL) in the revised World Health Organization (WHO) classification of hematopoietic neoplasms. It is rarely associated with leukemic phase. Most cases with leukemic involvement are the small cell variant of ALCL. These cases often lack the pleomorphism seen in the common variant of ALCL and may be misdiagnosed. We report a series of three patients who presented with leukemic phase ALCL. The patients included an 11-year-old boy, a 29-year-old man, and a 59-year-old woman. The clinical and pathologic features of these cases are reviewed. The patients in our case series with leukemic phase ALCL exhibited rare clinical features. The patients presented with massive extranodal disease involving cerebrospinal fluid (CSF), liver, spleen, lungs, and bone marrow. CSF involvement was documented morphologically as well as by flow cytometry in two patients. Two of the patients had small cell variant and the third patient had common type ALCL. The neoplastic cells in all three patients were ALK positive; however these patients died within months of diagnosis. Leukemic phase ALCL is rare, and behaves in an aggressive manner. Some, but not all, cases in the literature presenting with peripheral blood involvement had small cell variant ALCL, as seen in two of our cases. The leukemic phase of ALCL should be considered when a T-cell leukemia with unusual morphologic features is encountered.

Abstract
Pulmonary tumor thrombotic microangiopathy (PTTM), characterized by widespread fibrocellular intimal proliferation of the small pulmonary arteries and arterioles in patients with metastatic carcinomas, has been reported in only few cases. In childhood, gastrointestinal tumors represent less than 5% of pediatric neoplasms, and carcinomas within this subgroup have been very rarely described, in particular those arising in the stomach. We report on a case of a microscopic gastric signet-ring cell carcinoma identified by serial step sections through the entire stomach at autopsy. The patient was a 17-year-old high school student with severe dyspnea and marked pulmonary hypertension due to PTTM. Although the combination of PTTM with gastric cancer is very rare in childhood, it should be considered in the differential diagnosis of primary pulmonary hypertension and progressive respiratory failure, as indicated by a review of previously reported cases.

Abstract
A 56 year old man with previously unsuspected recurrence of squamous cell carcinoma of the oesophagus presented with dyspnoea. Bronchoscopy and computed tomography suggested bronchopneumonic changes with an infectious cause. He suffered a rapidly deteriorating course and died despite active treatment, including antibiotics and mechanical ventilation. Necropsy revealed a florid pulmonary tumour microembolism mimicking alveolitis. No bronchopneumonia was seen. The emboli arose from loosely attached tumour vegetations in the tricuspid valve. In a patient with known malignancy, tumour microembolism should be considered as an uncommon cause of rapid respiratory failure, refractory to antibiotic treatment.
